Growing Cactus From Seeds (Best Tips)

By: On:

A cactus is a great addition to the home, thanks to its shape, size, and impressive flowers. Since no cactus is the same, it is a unique and decorative way to add interest to your living space, whether on the windowsill or grouped on a shelf. Let us see the tips for growing cactus from seeds.

Native to America and normally found in drought-prone areas, cacti or cacti are perfectly adapted to live in the intense heat and desert environment, which means that they can definitely survive the hot, dry conditions of a centrally heated house. It is perfect for those who have less green fingers, as they only need moderate watering; in fact, it is better underwater than in water.

Growing Cactus From Seeds

Growing Cactus from Seeds

The germination time of the seed depends mainly on the species and the location where you are growing your cactus. When you choose to grow cacti indoors, they are more likely to germinate quickly. Interior is a more controlled environment and seed germination can take anywhere from three months to several months.

On the other hand, if you decide to grow your seeds outdoors, they take years to germinate. Here, cacti will have to wait for the ideal humidity and temperature to grow, as opposed to indoors, where you have the option of placing them on a window shade with light shade.

Cactus seedlings need proper care and protection. They need sun protection in the early years until they reach about 7 centimeters in length. Placing them indoors or in a shady spot is the best way to assist seed germination.

When they are about 1 inch long, you can start presenting them in the sun. Increase the light intensity and keep them off if they start to burn. If after some time you leave them comfortably on the windowsill consistently, it may be time to take them outside.

#1- Purchasing the seeds

The first step in planting cactus seeds is to buy them. Most garden supply stores sell seeds and you also have the option to buy them online. The great advantage of shopping online is that you can select your favorite species with a simple click on your laptop and delivery is made to your door. Some stores even sell seeds in packages of different species.

The other option would be to choose your own cactus seeds that are already in bloom if you grow them. Seed pods are usually brightly colored buds that produce flowers. Once the flowers fall, what remains is the pod.

Planting your seeds in late winter or early spring is the best time, as it will give seedlings plenty of time to grow during the summer.

#2- Harvesting the pods

As mentioned above, if you decide to harvest the seeds yourself, you must remove the fruits. It is recommended to remove the pods that are still damp, but not wet. The seeds are usually close to the pod.

After removing all the ripe fruits from your cactus, you need to remove the seeds. With a knife, cut the pods and scrape the seeds. Seed color varies from different species. Some are usually black or have some reddish spots. They also vary in size; some are extremely small.

#3- Exposing the seeds to the sun

After moistening the soil and covering the seeds with sand, it is necessary to cover them with a transparent cover or plastic wrap. Place your seeds in a strategic location, preferably indoors, where they have access to the right amount of sun. Consider placing them on a sunny window sill.

Monitor your seedlings carefully. If they start to turn purple or red, they are likely to burn in the sun. Reduce the amount of access to light.

#4- What to do when germination begins

As mentioned above, cacti grow slowly and you need the patience to observe them throughout the process. After planting and with adequate light and temperature, you should see your seedlings begin to germinate. It may take a month or more for this.     

#5- Transplant

When the seeds grow a lot, now is the time to transplant. Choose the potting container wisely, as you need one that drains quickly. You need one with drainage holes so that during watering, excess water is drained to prevent root rot.

How long does it take for Cactus to grow from the Seed

How long it takes for cactus seeds to germinate depends on the species and where you grow them. When you start growing cacti indoors, conditions are often more controlled than the unpredictable weather outside, so seeds can germinate more easily, anywhere from three weeks to several months.   

On the other hand, if you are planting seeds outdoors, they wait for the ideal temperature and humidity conditions to germinate, which can take several years.

Indoors, they usually germinate best when sprayed on the top layer of a tray with moist cactus soil that is placed on a slightly shaded window sill with a transparent lid on top. 

Fastest growing Cactus from seed

Echinopsis terscheckii is one of the fast-growing cacti that grow from seeds. Echinopsis terscheckii is not one of the largest species of Echinopsis; this attractive, fast-growing columnar cactus reaches heights of twenty-five feet or more.

Mature plants will develop side branches or arms 25 cm in diameter and eight to fourteen deep ribs with yellow spines. In late spring, it produces bright, white night flowers 20 centimeters long with outer segments from dark red to green.

Use as a substitute or in combination with the saguaro cactus, where a plant with a strong vertical accent is needed. Plant the cactus in open spaces, where you have plenty of space to grow and mature. This large cactus can also be used as an exotic plant in xeriscape gardens. The cactus is native to northern Argentina.                                                   

Easiest Cactus to grow from seed

Euphorbia Trigona is one of those easy to grow cacti from seeds that make every grower feel like an expert. Also known as a cathedral plant, this cactus can grow over 2.5 meters in height, but it grows slowly and is unlikely to grow more than one meter indoors.

Small green leaves grow between the thorns on the striated stems, and if you grow the Rubra variety, the leaves are reddish-purple. If you plant it in well-drained soil and water it twice a month, your African molasses can live for decades.

They need full sun to partial shade. Euphorbia Trigona needs water twice a month. They have reddish-purple leaves.

How to grow Cactus from Cutting

Cactus is easily propagated from cuttings. In most cases, you will get faster and more predictable results by harvesting seedlings than by planting seeds. It is more common to propagate cacti indoors, but you can also do it outdoors.

How to grow Cactus from Cutting

Since you cannot control the external conditions, take special considerations when choosing this method. When planted correctly, most cuttings will take root in four to six weeks.

Grow Cactus from Leaf

  • Select a healthy leaf of the cactus to cut, preferably a new leaf from the current or previous year. 
  • Cut the section at a 45-degree angle to the mother plant to prevent moisture from accumulating in the mother’s wound, promoting rot.
  • Align the cut wound with the knife so that the cut angle is perpendicular to the shank.
  • Leave the cut aside for at least 14 days to allow it to develop a callus where it was cut.
  • Immerse the hardened cutting edge of a compound for rooting plants to assist in the production of roots.
  • Bury the stake between a third and a half of the stem to prevent it from falling. Choose a partially shaded outdoor location, such as under a tree, to plant most cacti. Choose direct sunlight for the species Cereus peruvianu, Lophocereus, Pachycereus, and Stenocereus.  

How do you Propagate Cactus Leaves

  • You can propagate cactus leaves by adopting these methods:
  • Water infrequently, as cacti are susceptible to rot when over watered.   
  • Examine the plant in late spring for new growth. With a clean knife, cut a stem that contains three new leaf segments.
  • Place the cut on a paper towel in a dry place, away from direct sunlight. Allow the cut end of the segment to dry for 24 to 48 hours. The cutting of the cutting avoids rot and disease during the rooting process.
  • Fill a 4-inch-diameter pan with a well-drained, sterile potting mix. Use a pot that has at least one drain hole. Water the potting mix until moisture drips from the drain hole and the mix is ​​evenly moist.
  • Insert the cut end of the 1-inch cut into the potting mix. You can plant up to three seedlings in a 10 cm pot.
  • Insert two wooden skewers into the soil on opposite sides of the pot. Place a plastic bag over the pan. The skewers prevent the bag from touching the seedlings while retaining soil moisture and air humidity during the rooting process.
  • Place the pot in a warm room where the seedlings can receive bright but indirect sunlight, as sunlight can burn the leaves of the rootless cactus. Remove the bag and water the soil if it starts to dry during this period, but do not overwater, as this can cause the seedlings to rot.
  • Remove the bag as soon as the seedlings take root, which usually takes three to eight weeks. Rooting is evident when new growth begins at the cuttings. 

Can you cut off a piece of Cactus and plant it

Yes. Cacti can produce new plants from cut pieces of the main cacti. The method of cutting depends on the shape of the cactus. Varieties that produce segmented leaves or stems generally propagate from these segments.

Some cacti, such as those of the barrel type, produce new smaller plants around the base of the main plant. You can remove one of these smaller plants to make it a new cactus. Removing the cut and transplanting it properly prevents damage to the original plant and helps ensure that the new cactus grows well.

  • Cut a segment of the cactus with a clean knife, select the segment of the new vegetation, and cut through the segment joint. Remove small plants from the base of a cactus by cutting the base of the new plant just below the surface of the soil.
  • Place the cactus stake on a paper towel in a dry place, away from direct sunlight. Position the segment and barrel cutouts so that the cut side is exposed to the air and does not touch the towel. Let the cut heal overnight, minimizing disease problems, such as cutting roots.
  • Fill a 4 to 6-inch diameter pot with pot soil formulated for cacti. Select pots with drainage holes at the bottom so that the soil does not retain too much moisture.
  • Insert the cut end of the cactus segment piece into the soil just enough for the piece to stand on its own. Push the barrel stakes into the soil so that the bottom 1/4 to 1/2 inch of the cut end is buried in the soil. Water the soil enough so that it just stays moist. Too much moisture causes the transplanted cut to rot.
  • Place the pan in a warm area that receives indirect, bright sunlight. Water the soil when it is almost completely dry, keeping it just moist. Cactus cuttings usually take root in three weeks, which is indicated by the new growth on the stake.

How often should Cactus be watered

As they grow, cacti and succulents should be watered at least once a week. Some people water more often than that. During each watering, wet the soil well so that the water comes out of the ‘drainage holes’ of the pots. When the weather cools and the length of the day decreases, the plants enter a period of rest.

During this time, increase the interval between watering and let the mixture to dry between watering. Some people say that during dormancy, cacti and succulents should receive enough water so that they do not show signs of wilting.

Use common sense here. If your plants are kept indoors, on the windowsill in a heated room during the winter, they will need more water than if they were to spend the winter outdoors.

“Cacti” is short for a specific family of Cactaceae plants , but that general term cove a wide variety of types that live in drastically different habitats and have very different needs. Many, like those of the genus Ferocactus, are typical hardy desert inhabitants who need little water, but the genus Echinopsis (from the pastures of South America) and the genus Oreocereus (from the high mountains of the Andes) need a little more of water. The genus Epiphyllum (from the jungles) – a cactus that has roots in trees instead of in the soil – likes colder and more humid habitats. The decision on how much to water depends on:                          

  • The type of cactus you have
  • What is your normal growing season
  • The temperature, soil and conditions typical of its original habitat
  • What kind of temperature, soil and conditions are you growing up in now   

Can you propagate Cactus in the water

Yes. You can propagate cacti in the water. A pencil cactus can easily propagate in water. After making a cut, immerse it in fresh water to stop the flow of latex. If you need to use tap water, let it sit for 48 hours to allow the salts and chemicals to evaporate.

Fluoride is especially harmful to young seedlings, as it travels through the plant in the water and settles on the edges of the leaves. This causes the edges of the leaves to turn brown, which will spread if you continue to give the plant fluoridated water.

Keep the water level just below the plant’s stem. When you are ready to root the callused stake, let it float in the water, without touching it. This creates a stimulus to stimulate the development of the roots. Wait patiently for a few weeks for the root system to grow. Place it in a crescent light or bright light outside.

How long can a Cactus live without Soil

They will survive without land. But will they thrive? Not for long. Think of it as fun short-term projects that shouldn’t last long.

Cactus comes from dry areas, deserts and semi-deserts. Conditions that is normally too severe for other plants to survive, such as high temperatures and little rain, have made these plants extremely resistant and adaptable but not make them able to survive without soil.

Is it bad to have Cactus at Home?

According to basic Feng Shui principles, placing cacti in the living room, bedrooms or main entrance can make it a place of conflict, rather than a place of cooperation and harmony. A cactus can cause bad Feng Shui if it is placed in the wrong area.

Putting cacti in the room can disturb sleep and peace. While plants bring positivity to your home, cacti are an exception. Cacti are beautiful plants with strong protective energy, but their spines are a problem.

Like pointed objects, they look like thousands of tiny arrows that fire energy into the surrounding space. That is why cacti should never be placed in a living room, bedroom, or front entrance.

The living room is an area to relax. By placing a cactus there, they can constantly “nudge” it with its sharp points, causing all sorts of discomfort.

A bedroom is where you find comfort and peace while sleeping. You don’t want any form of negative energy to disturb your peace and sleep. If you have a cactus in your room, it can be “poked” from time to time.

Putting cacti in the kitchen can spoil the flavor of the food. The kitchen is a place where you cook and prepare drinks for family and guests, and you don’t want your dishes to taste bad.

Putting a cactus in the kitchen would likely spoil the flavor, as it emitted negative energy that could be transferred to the meals you are preparing and, eventually, to the people who eat the food.

Do not place your cacti too close to the entrance or the front door. You want this area to be as free as possible so that fresh and refreshing energy can enter your home.

Does Cactus need Sunlight

Cactus that do not receive sufficient light exposure may also turn pale or return to their original green color. In contrast, plants that receive adequate exposure to light demonstrate their true beauty by displaying a wide range of vibrant colors.

Typically, most cactus species need at least four to six hours of sunlight to thrive. These plants love to be in bright, sunny places. Plants that do not receive sufficient exposure to light can show a wide range of signals.

Perhaps the most common sign that your plants are not getting adequate light is the blanching/stretching. This is a process by which plants stretch to seek more light. Although it may seem like an excellent self- adapting mechanism, isolation produces weak stems and can result in poor growth.

Too much sunlight is what causes sunburn and sun damage in cacti and other succulents. The unfortunate thing is that sunburn can happen quickly during a heatwave or when temperatures soar. Sometimes, the process can also happen gradually.

The first sign of sunburn is the appearance of brown/yellow spots on the plant’s surface. Fortunately, if you notice the signs of solar stress early, the effects can be easily remedied to prevent further damage to the plants.

Simply move your plants to a shaded area or place them next to other taller plants to protect them from excessive sunlight. If you do nothing, even after noticing the signs of solar stress, some cacti will fry and die.

Can you replant a Cactus without Roots

Yes. You can replant a cactus without a root because it can survive without it. Cacti can produce new plants from cut pieces of the main cacti. You can even grow a new cactus from a broken cactus.

How long can you go without watering a Cactus?

 Typical desert cacti can survive up to two years without water. This is because it has developed thick rods that store a lot of water and have a protective cover that prevents water loss. However, this does not apply to indoor cacti because the conditions are quite different. Indoor varieties require frequent watering, depending on the species.

As resistant as these desert plants are, they cannot survive without water forever. Science tells us that a cactus is a living being and all living things need water to survive. These desert plants generally use the water stored in their roots and the stem is much more efficient compared to non-desert plants.   

They do not give up by evaporating the water as easily as other plants, since they have no leaves. This may make you think that cacti have developed deep roots to help them get more water from the soil.   

Instead, they have an extensive, shallow root system that remains just a few inches above the ground. The roots can also extend a few feet from the plant to help collect as much water as possible. They also tend to take root more quickly when the rains come and wither and cease as soon as the dry season begins to help you store your water supply.

What does an Unhealthy Cactus look like

Some signs appearing on your cactus that show you are not healthy for the plant.

  • Discoloring cactus: A cactus will acquire a shade that is not its nature. Depending on where the problem comes from, the color change may start at the top end of the stem segments or at the base of the soil. Death is guaranteed if quick action is not taken.
  • Fallen leaves on cactus: The death of some leafy cacti (such as the epiphile ) is indicated by leaves pointing downwards that lack vigor. This gives the cactus an overall unhealthy appearance (because it is, right?). It will also appear underwater, even when you are excellent at turning it off.
  • Soft segments around your cactus: The color change above can be accompanied by soft segments of the stem that look swollen. It also means that they can break easily with minimal applied force. Try to pull out a thorn. It is a dying cactus, if you can pull the specialized leaves.
  • Soil instability for cactus potting: You will know if the plant is lean. Not folded, just the entire plant tilted to a specific side. A dying cactus is shaky in its potting mix and may look like it is about to fall; well, it will definitely fall if you move it, for a bad case. The existing ones may be too weak to adequately support the plant. This assumes that you have placed the plant pot correctly.
  • Bad smells coming from your cactus: Now, this is a very bad sign. A bad smell means that a large part of the cactus is completely rotten and there is nothing you can do to save it. In other words, he is no longer in the process of dying; in fact, he has passed away. All you can do now is to get rid of your fighting cactus plant and get a new one, either from a purchase or from a friend.
  • Inadequate culture medium: If you didn’t receive the note, your usual potting soil is a no-go zone for a cactus. It just retains water for longer than your plant prefers. So, even if you water properly, the soil mix will delay you a few steps. Long periods of humidity are good conditions for rot. And before you know it, your plan shows signs of dying.

How do I know if my Cactus is Healthy

If you want to check the health of your roots, carefully pull the plant out of the soil. Healthy roots must be white. If you can see the actual color of the stem, you will not have much trouble determining how your cactus is doing, because there will be a change in which the “healthy” green will change permanently.

How to cut a Cactus and replant

There are a few different ways to propagate succulents. Here are some simple steps to follow to cut and replant your cacti successfully:       

Step 1: Disinfect your tools. Use a sharp knife or razor blade. Pruning shears are not ideal for making clean cuts. You want a clean cut and avoid uneven edges or cactus fabric. Make sure that the knife or blade you are using is clean and sanitized to prevent the spread of disease. You can wash them with warm soapy water or use alcohol wipes to disinfect them. Take care to disinfect each time you cut, cleaning the tool to prevent the introduction of fungi and diseases.       

Step 2: Protect your hands and fingers. When handling prickly and prickly cacti, it is always a good idea to wear gloves and use tools such as tweezers or pieces of cloth to protect your fingers and hands.

Step 3: Cut one of the pads. Select a cushion to cut. Ideally, you want to choose a healthy plant for the best success rate. Avoid using tampons with visible signs of stress, illness or discoloration. Sometimes pillows break easily. Just grab a cactus pad with your tweezers or a piece of cloth to break the main plant’s cushion. You can also use a sharp sterile knife to cut one of the pillows.

Step 4: Let it dry. After the cut, let the pads dry for a few days to allow the wound to heal and go numb. Keep away from direct sunlight while drying.

Step 5: Immerse yourself in the rooting hormone (optional). Once dry, dip the cut portion of the pad into the rooting hormone. This step is optional and you can decide to skip it entirely.

Step 6: Plant the stake. Prepare a potting mix suitable for well-drained cacti. You can plant the dry cut in the potting mix by gluing the cut part into the soil. About ⅓ of the cut should be on the floor. Pack the dirt around the cushion to secure it so that it doesn’t tip over.

Step 7: Water in moderation. Wait a few days before wetting the newly placed cushion. You can spray the soil every few days or when the soil looks dry. Once the roots are established, decrease irrigation and let the soil dry before irrigating again.

Step 8: Stay out of direct sunlight. Place it in a well-lit place, but protect it from direct sunlight until the roots are established. You have a new plant. The roots will take several weeks to establish. A few months later, you will notice new growth and have a new plant. You can slowly increase the amount and intensity of sunlight to avoid burning the plant.
