Growing tomatoes in a grow bag
A grow bag
is a mini-garden in itself. It offers many advantages over growing tomatoes directly in the soil or in large containers. In addition, growing tomatoes in grow bags is one of the most popular ways to grow tomatoes in the UK. Here are some of the reasons why!
Benefits of grow bags
A grow bag is a self-contained, disease-free environment that provides the best possible start for young plants.
A quality grow bag contains all the nutrients needed for the first six weeks of growth.
It can't be blown over by the wind, unlike a cauldron!
It contains enough soil to grow three tomatoes.
The grow bag helps protect the plants from slugs, snails and other critters that like to nibble!
Grow tomatoes in grow bags and use grow bag pots.
Best tomato varieties for grow bags
The ideal variety to grow is a tall, cordoned and indeterminate tomato plant. These are plants that grow tomatoes from tall stems on trusses.
Optimal placement of grow bags
Because tall species need support, it is ideal for growing against a fence or wall. Support canes are used to support tomato plants, which are then tied to hooks/nails on the fence or wall.
Of course, sunny areas are best for tomatoes, but if your garden faces north, place them in as bright a location as possible. Cherry tomatoes can still grow successfully without full sun if the plants have enough light.
How to grow tomatoes in grow bags
Loosen the soil
When you bring your grow bags home, you will find the soil is very compact. Roll it back and forth on the ground to loosen the soil inside. It is important to loosen the soil before planting so that a lot of air gets into the soil. This will help the roots to grow better if there is enough oxygen between the soil particles.
Insert a pencil hole and two at each end of the grow bag so that excess water can escape. On a cold night, you don't want your best tomato plants buried in concrete!
However, it is important that the entire soil area is moist so that the roots can absorb soil nutrients. Dry soil will often lead to tip rot and other problems.
If a hole is inserted in the middle/side of the grow bag, water may escape before the entire soil area is watered.
Space three holes evenly across the top of the grow bag, about 6 to 8 inches in diameter. Loosen the soil underneath. If there is some perlite, add a handful of perlite and push the soil underneath to the sides to create a decent-sized hole.
Remove the baby tomatoes from the pots, loosen the bottommost roots slightly, and plant them in the grow pockets.
You do not need to water the pockets for the first planting. Simply give each plant a pint of water. After a few days, they won't need any more.
Young tomato plants do not need a lot of water. After the first watering, let them continue to grow without more water for a few days so their roots can grow and establish.
The more water the roots have, the less air there is in the soil. Roots need water and air.
In addition, the roots will grow as they search for water. If there is too much, the root zone will become smaller and less developed.
Planting bag optimization
Make sure the soil is loose before planting
Add drainage holes at both ends of the grow bag
If possible, add a small amount of perlite to each plant
Do not over-water
After the first watering, look for water while allowing the roots to develop and grow
Place pots in grow bags for watering
Use grow bag pots to increase growth

Growing tomatoes in grow bags is a great way to get very good results each summer.
Tomato plants can produce hundreds of tomatoes, even outdoors, if they grow well and the weather is good!
