Best Time To Grow Tomatoes:

We all know tomatoes are warm-weather sun-loving plants. So they need a hot climate to grow at their best. Here are some factors you can use to see if time is right for tomato plants:

  • If the temperature of nights stays above 50-degree Fahrenheit or 10-degree Celcius, the time is right.
  • If you are growing seeds in the greenhouse and have some heat source, you can sow seeds early as long as the temperature is optimal. 

When not to grow tomatoes?

Some people start to grow tomatoes early, so they can get an early harvest. But this is not going to work out, because tomatoes plants will produce flower but not gonna produce fruits. Tomato plants need 55 plus degree or 10 degrees Celcius (night time temperature) to produce fruits. If you have a greenhouse and heat source, then you can grow them a little early. 

When is too late to grow tomatoes?

If you wait a little too much longer to start growing, and wondering if your plants will produce fruits or not. Then you have to choose varieties of very little growth time. Varieties with a growth time of 60 days or less are best. If the first frost time of your area is less then 60 days, this may be a problem for you. Again if you have heat source you can go for it. 

Seeds Or Seedlings?

Let’s be honest with each other. Growing with seeds and watch them grow is the most satisfying thing ever. In 5-12 days the seeds of tomatoes germinate. And in 6-8 weeks the seedling will be ready to transplant in Grow Bags. 

But if you wanted to cut this time, you can always buy some seedling from the store. Starting with seedling will save you time. And you can choose the healthiest seedling from the store. The only con of seedling is, there are not many varieties available in store to go with. If you have no problem choosing the same varieties over and over, then I suggest you go with the seedlings.

Step 2:

Add some clay pebbles at the bottom of your grow bag. If your compost is good and has well drainage percentage, there is no need to add pebbles in grow bag.

Step 3: 

Add soil in grow bag. You can add compost in the bag. Good compost is highly recommended. You can buy good compost from stores or you can make your own compost. 

Step 4:

Now the compost in the bag, shake the bag to loosen it up. You don’t want compact soil in bag.  Shake until the soil inside the bag loosens up.

Step 5:

If your grow bag has drainage holes at the bottom, then skip this step. If your bag doesn’t have holes, then pick a scissor and make some hole at the bottom. These holes are necessary for the release of excessive water. 

Step 6:

Now place your grow bag where you want. We are growing tomatoes and tomatoes are sun-loving plants. So pick a place where sunlight is abundant. You can put grow bag on the roof and balcony too. 

Step 7:

Now Pick a healthy seedling with healthy roots. Plant the seedling in grow bag. Scoop out the compost and make some room for seedling and plant it. Cover all the roots of the plant with the soil. 

Step 8:

Water the plant. Grow bag plant will need some extra water for best growth then potted plants. Any time you see the soil is drying, water the plant. Soil moisture is very necessary for the growth of tomato plants. 

Step 9:

As plant growing and gaining some height, some kind of support will be required. There are so many different kinds of support you can give to your plant. 

  • Simply use a rope to support the plant.
  • Make some wood trellis to support.
  • Or you can buy a trellis to support the plant. 

How To Use Compost Grow Bag To Grow Tomatoes?

Step 1:

Buy some good kind of compost from the store.

Step 2:

Shake the compost bag to loosen up the soil in it. Do not plant the seedling in compact soil. 

Step 3:

Cut the slot from 3 different places out of the bag. Do not cut too many. 3 slots are enough in a bag. 

Step 4:

There are two ways you can plant the seedling of tomatoes in the bag. First, plant directly in the soil or use some growth rings. If you wanted to use the growth ring, then push the ring in the soil a little bit. And then plants the seedling.

Step 5:

Now water the plant. If you are using a growth ring, then watering is easy and more beneficial then another way because the water goes straight to roots. 

Cons Of Using Compost Bag Directly As Grow Bag:

  • There is not much area for roots to spread in the soil.
  • The hight of the bag is only a few inches (2-3). Which is not in case of other special grow bags.

Best Practices For Growing Tomatoes In Grow Bags:

Protect Plants From Pests: Because grow bags are very close to the ground, the pests and sludges can easily crawl to plant and destroy them. So use some kind of grow bag tray or anything that keep sludges away from young plants.

Nutrients: There is only a limited supply of nutrients available for the plant in the bag. Tomatoes plants are heavy feeders. So after running out of nutrients, we need to add some extra nutrients. Add some all-purpose vegetable feed in the soil. 

Water Supply: The optimal supply of water is the most important thing if you are growing in grow bags. Too much water can cause tomato splitting and less water can kill the plants. Little and often is the best way to give water. 

Cut Leaves: Every leaf or stem which is touching the soil, cut them. Because they can easily attack by the fungi and harm the whole plant. So cut them off the plant.

Prevent Diseases Of Tomatoes Plants: 

There are so many diseases of tomatoes. I’m not going to discuss all the disease, that will require another article. But here are some tips you can apply to save the plants from disease.

Change The Soil In Grow Bags: Pathogens of tomatoes live in the soil. So it is good if you change the soil or rotate the crops.

Pinch of Leaf: Leaf or stem which touch the soil, pinch them off. They can be the start of fungal infection. 

Wet Tomato Foliage: When the foliage of tomatoes is wet, do not work in the garden. You can transfer the pathogen from one plant to another. 

Burn The Disease: At the end of the season, do not use the diseased plant in the compost pile. Burn them or through them away. 

Pests Of Tomato Plants:

Green Aphid and whitefly are tiny pests of tomato. They cluster underneath of leaves. It is better if you remove them with your hands or just cut the effective leave. If the attack is severe, then spray on plant. Water with a small amount of washing up liquid will do the trick.

Harvesting The Fruit:

The best way to check if the tomato fruit is ripe or not is to taste it. Pick one and taste it, if it is okay, then harvest other fruits. You can also use colour as an indicator. But the colour depends on the variety you are growing. 

Fresh tomatoes always taste good. Do not harvest green tomatoes. If frost is here or you wanted to harvest all of them for some reason then separate the green one and put them in a warm place until the ripe. Piling up is not a good idea, single layer in some container and a warm place, about 22C or 77F temperature is best.
