When we use Square foot gardening tomatoes plantations are even more easy and rewarding since they use up small spaces to grow more plants and give higher yields increasing efficiency. When using square foot gardening we have to start with raised beds of 4 feet by 4 feet or 4 feet by 8 feet and then we have to divide this bed into small areas of a square foot each.

We can also use wooden frames of the square foot with 6 to 7 inches depth for that matter. Then we plant one kind of plant in each square foot and depending upon our need for the plants we can use any number of square foot areas to plant the trees we want to. So let us start to discuss how to grow tomatoes in square foot gardening.

#1. Temperature requirement

For Square foot gardening tomatoes, the temperature requirement is very important. Being a plant that loves warm growing conditions, tomato plants don’t do well in cool soil. These plants do not like frost and cannot tolerate the frosty cold seasons therefore we must start our planting season during the spring season after the last frost when the soil temperatures start increasing. The ideal soil temperatures for growth are 70 degrees to 90 degrees Fahrenheit

So after the spring when the temperature starts to increase we can grow our tomato plants as they don’t like temperatures falling below 55 degrees Fahrenheit. The right time for you to start planting tomato plants will differ according to the zone of America that you live in.

Some areas will get the right temperature for growth till April and may so you can decide the right time according to the temperature conditions of the area that you live in.

#2. Sunlight

Another important factor for Square foot gardening tomatoes is the proper amount of sunlight. Tomato plants love good sunlight conditions to grow well. In order to have a healthy harvest, we must provide the crops with the sunlight of 6 to 10 hours each day.

When the plant will get such direct sunlight conditions it will thrive to give higher yields and in case of the low amount of sunlight the plants will tend to survive but the yields will be likely to reduce accordingly.

When you are deciding the place to grow your tomato plants choose such a place that gets abundant sunlight of 6 to 10 hours per day and also choose a site where there are no tall trees or plants next to the tomato plants that may block the sunlight coming on them or the rest of the garden.

#3. Potting mix

One of the main factors that make a square foot gardening successful is the potting mix. When we are using square foot gardening ways then we are planting the crops in limited space to provide maximum yield and hence it is important that the potting mix or the soil that we are using should be very rich in quality to provide all the required nourishment to the plants and help them grow well. 

A great option of using a potting mix for great nourishment is that we can use compost, vermiculture, and peat moss in equal ratios. This mixture is great for providing the required nutrients to the plant. We can also amend the soil with a good amount of compost.

However, the potting mix that we use should be well-drained so that they do not cause waterlogging in the plants that might damage them.

#4. Spacing and planting seeds

For planting the tomato plants in a square foot gardening, we can directly plant the seeds in the ground during the right planting season. Also, we can also plant the seeds indoors 6 to 8 weeks before the average last frost season and then transplant the seedlings when the outside temperatures rise to match the temperature requirements of tomato plants.

These seeds or even seedlings can be purchased from the online market or the local markets. However, as a recommendation beginners can start with buying transplants or seedlings from the market. We can make a hole in the soil and plant the seeds or the seedlings in it and cover it up with a potting mix and water it.

Even though it depends on what kind of tomatoes you are choosing to plant and grow, most of them are climbers and need some support system to grow well in the form of vines.

So at the time of planting the seedlings or seeds, we can also add stakes, sturdy poles, or any such support systems so as to avoid damage to roots later on adding them. The usage of supports like trellis also helps in utilizing the space vertically.

In a single square foot space, we can grow a single plant and they can give about 20 pounds of produce each.

#5. Water requirements

Water is a very important component of a successful tomato garden. We should make sure that we provide the plants with ample water to grow and especially during the dry weather as they will require more water in dry weather than usual.

Make sure that the plant does not be water deprived but also we should take care that we don’t overwater the plants. 

Overwatering the plants can cause the roots to rot and damage the crop. For that matter, we must take the soil or potting mix that has good drainage so that the crop doesn’t rot and get damaged. Also in case there was rain in a particular week, see that we water the plants only if sufficient to prevent overwatering.

#6. Pruning 

When we are growing tomatoes it is a good option to prune the leaves of the plant to save the energy on maintaining tones of leaves that the plant can utilize to give more yields. This pruning of leaves will also prevent the tomato plant from wilting and dying and hence we should prune the leaves regularly for healthy produce.

We can prune the lower leaves of the tomato plant and make the plant go deeper in the ground since the plant has the ability to grow more roots on the submerged stems and hence it makes the plant stronger. Also when the plant is pruned it gives way to the sunlight to enter the plant and we know that good sunlight is important for good produce.

#7. Harvesting

It depends on many factors that the cultivator has to take care of as already mentioned to make sure they get good produce and harvest. However, depending upon the type of tomatoes you are growing ideally the harvesting time may range from 60 to 80 days.

When the harvest time comes you can pick fresh tomatoes right from your own garden and savor or store them as you wish to.

All of this will lead to stunted growth and the plants will die in the end due to lack of sufficient resources. Lastly, you should know that every plant needs space for themselves to bear good fruits and good growth. Well, giving them their space will be the best thing.

Frequently Asked Questions

1. How moist should soil be for tomatoes?

Keeping the soil moist is of utmost importance. It is believed that the soil needs to be moist and damp for at least 6 – 8 inches below the ground so that the water reached the roots for good. Also, moisture does not mean overwatering the plants. It will ruin everything and even rot the roots from the ground. Giving an ample amount of water is necessary. Moreover, the right kind of potting mix for the base is important as well since the best ones keep the soil moist as needed.

2. Why are my tomato leaves curling up?

As we have discussed several times. Tomato plants need proper resources for healthy growth. If the winds are too high, low humidity, dust, etc can lead to damaging the tomato plant. With too much heat and low moisture, your plant can start to curl up or better say gry out and dampen the process. You will experience it with other plants too when due to too much heat the leaves tend to roll up and dry out.

You might have known by now that Tomatoes do like moist soil at all times. But too much water in the soil can be very harmful. If you are planning to water the plants at night, we would recommend not to continue with it. The main reason is that during the day time after you have watered the plants, the heat of the sun leads to evaporation of excess water.

However, this is not the case at tonight’s time and hence the water will remain intact in the soil for the entire night and rot the roots one by one. You may never want it so it is always better to water them before 12 pm so that everything works out for the best.

4. Do tomatoes like wet or dry soil?

Well, tomatoes like moist soil to be precise. Not too dry but not too wet as well. There is perfect potting soil that retains water and keeps the soil moist at all times.
