How to make plants green again

Both professionals, as well as home gardeners, are aware that there is no one reason why plants lose their luster and color. If you look for a broad classification for the reason why leaves lose color they are

  • Nutrient deficiencies: nitrogen, sulfur, phosphorus, iron, manganese, oxygen (from waterlogging)
  • Toxicities: phosphorus, pesticides, over-fertilization
  • Other causes: wrong light, root rotting, pot bound, high temperature, naturally pale new shoots.

How to make plants green again by treating Nutrient deficiencies

All said and done when it comes to zeroing on the causes of discoloration or dullness in the leaves of plants, a thorough diagnosis needs to be made. This is not something that can be done in a day, it requires careful examination of the plant and an understanding of the conditions in which the plant is growing.

External conditions like over or under watering are easier to detect as compared to mineral deficiencies. Most discoloration happens when leaves lack a chemical called chlorophyll, this chemical is vital for photosynthesis. The minerals required for the production of chlorophyll are present in the soil and absorbed by the roots.

It can so happen that some minerals in the soil are missing. This is when the right amount is not absorbed and the plant cannot produce enough chlorophyll. This is when discoloration takes place.

How to make plants green again by treating nitrogen deficiency?

Nitrogen as an element in the soil has the greatest impact on the color of leaves. This is one mineral that is required in substantial quantities but in most soil types is always missing. This is the reason most fertilizers come with a higher quantity of nitrogen. Nitrogen is essential in the production of proteins, enzymes, and chlorophyll.

Nitrogen deficiency starts in the older leaves. These start to turn pale green eventually turning yellow with or without a red tint. The overall growth rate is reduced and the plant seems dull.

Nitrogen deficiency in the soil can be tested by using home testing kits available at local stores and over the internet. If you are skeptical of getting a test done at home the local extension office offers testing services at a small fee. You can get them to come in and test your soil.

After testing and getting positive results of deficiency there are two ways in which you can tackle the problem. One is by going the organic route and the other by choosing a non-organic solution.

Organic correction of the nitrogen levels in soil takes time and results in a more even distribution of nitrogen in the soil. Some methods of increasing the nitrogen level in the soil organically include

  • Adding compost manure to the soil
  • Planting green manure crops such as peas, beans, etc.
  • You can also add a coffee ground to the soil 

Non-organic methods of increasing the nitrogen content of the soil is faster and can be achieved almost instantly. When choosing fertilizers to boost nitrogen content look for those that have a high first number.

The contents of fertilizers are numerically represented in the form of a ratio for example 10-10-10 is the NPK ratio. A higher first digit means a higher composition of nitrogen in the fertilizer.

Note: Non-organ fertilizers act fast and boost the level of nitrogen level of the soil almost instantly but also fade away quickly. Reapplication is advised in most cases.

How to make plants green again by treating phosphorous deficiency?

Phosphorous like nitrogen is important to plants for photosynthesis. The role of phosphorous is to capture, store, and convert the sun’s energy into biomolecules.

This process goes on from germination to maturity of the plant and hence and deficiency in the phosphorous levels in the soil causes an overall decline in the health of the plant.

Visually you can identify phosphorous deficiency when the leaves are abnormally dark green or reddish-purple along the edges.

Phosphorous is mainly used in flowers, fruits and for seed production, a deficiency will normally show as a purple hue on leaves. This is normally on the oldest leaves they will eventually turn yellow. The plant will also have a stunted growth

This is normally noticed in colder temperatures, in early spring for example places where the PH of the soil is below 5 you see a deficiency of phosphorous. Dry soil can also induce a deficiency in younger plants.

Other factors that contribute to phosphorous deficiency are soil compaction, herbicide injury, insect pressure, and poor soil health.

The phosphorous levels can be tested in the same way you would test nitrogen, using a home testing kit or getting an official test report.

Once positive you can add organic manure, this can take time to act on the soil but will provide a wholesome solution to plants. If you prefer a non-organic solution you can look for fertilizers that have a high phosphorous content.

How to make plants green again when they suffer from potassium deficiency?

Potassium is another major mineral that is present in most fertilizers. The reason this mineral is important is that it helps plants absorb nutrients from the soil required for optimal growth.

In comparison to the other two, it is not very important to plants but its deficiency can be noticed almost immediately.

When testing for potassium deficiency you can combine it in a single test by getting an in-depth analysis of the soil. You could also get a self-testing kit that gives you results in minutes.

If you notice that the mature leaves of your plants are yellowing around the edges and nitrogen infusion is not doing the trick. It probably is time you give the soil a potassium boost. This can be by adding organic manure or kelp meal or greensand. You could also look for non-organic fertilizers with a higher potassium content.

You will not need to do much as the addition of potassium will eventually happen when you feed the soil with other fertilizers.

When it comes to planting discoloration due to minerals, other than the major 3 we have other minerals. These not only cause the plant to lose color but also stunts growth. Here is how to make plants green again when the soil lacks minerals. Here is what you need to look out for and how to deal with it effectively.

If this is the case it can be treated naturally by adding blood and bone manure, and organic fertilizers containing nitrate, ammonium, or urea. This will increase the nitrogen content and make the plant green again.

#2 The leaves of the plant turn yellow between the veins and the plant suffers from slow growth.

When the leaves of your plant start to turn yellow between veins it is indicative of the fact that the plant lacks magnesium. These are considered to be secondary nutrients needed for plants in large quantities.

When there is a deficiency of magnesium in the soil younger leaves begin to show yellowing first. The veins of these leaves remain green but are faint.

The best solution for this situation is to spray the plant with a manganese chelate solution. If this does not reduce the symptoms, you could also try an iron chelate spray.

In the next section, we will look at other reasons why plants lose color. This includes Toxicities like phosphorus, pesticides, over-fertilization, and Other causes including wrong light, root rotting, pot bound, high temperature, and naturally pale new shoots.

Leave tend to change color ranging from a light yellow to burnt brown especially if the plants are overfed. This generally happens when too much fertilizer is added to the soil or when the salts in the soil are not washed off completely.

This may happen when you do not estimate the size of the pot and add in too much fertilizer or use it too many times in a garden. Either way, this causes the leaves to burn and wilt.

Over-fertilisation in some cases can cause paleness in the youngest leaves and tender parts of the plant. You will also notice the tip burning of older leaves.

The only way to make this better is to reduce the amount used and wash out excess.

The same is the case with pesticides. As we know it pesticides even the ones marketed as organic come laced with chemicals. They are used to keep insects and pests off the plant but while doing so they also form a layer on the leaves of the plant.

When you do not wash them off or use fertilizers that are too strong, they burn the leaves causing brown to black patches. This can be controlled by watering down the chemicals and at the same time keeping an eye on the ingredients and staying away from harmful chemicals.

Other factors that can cause discoloration in plants include

Overwatering plants cause oxygen deprivation. This in all senses is a recipe for disaster. When the plant does not receive enough oxygen it starts to turn yellow. This is a greater concern when you have potted plants and the mix used is not light enough or you do not have drainage holes at the bottom of the pot.

Overwatering or waterlogged soil not only reduces the amount of oxygen the plant receives but also increases the chances of root rot. This will eventually cause the plant to discolor and wilt over time.
