Containers for Tomatoes - Surface Area

In the UK we usually grow our tomatoes in containers.

There are many different shapes and sizes of container for tomato growing, each having its own pros and cons. For example, grow bags are great for tall varieties and have a large surface area for oxygen absorption by surface roots.
The disadvantage with such a large surface area and shallow depth of soil is that soil or compost dries out quickly.

A high sided pot is great for trailing tomatoes to tumble over the sides, keeping the tomatoes off the ground. However, it has a much smaller surface area than a grow bag so to optimize a tall pot, adding perlite or vermiculite can be useful in getting air down into the root area.

If you are new to growing tomatoes, it's a good idea to know the best time to sow in your part of the world to get the best results.

There are a lot of different tomato varieties which need the right container or position.

For example, tall tomato plants do well in grow bags, tumbler type tomatoes are great for hanging baskets and tall sided pots/containers. Dwarf bush varieties do very well on the kitchen windowsill.

Various Media For Sowing Tomato Seeds

Usually, tomato seeds are sown in seed compost but there are a number of other ways to sow tomato seeds that may be more convenient and a lot less messy than using compost.

Rockwool, sponges and Jiffy Pellets are great for sowing tomato seeds.
There are a number of advantages by using each of these media.
  • Less messy
  • No pricking out
  • Better moisture and air holding capacity than most seed compost
  • Potted on without disturbing roots
Seedlings are potted on with the cube, sponge or pellet so there is no root disturbance and they can be potted into potting compost, rockwool or any suitable media for growing tomatoes.

When To Sow Tomato Seeds

The short answer is eight to ten weeks before your last frost - but why do we sow at this time?

Sowing tomato seeds at the right time can help avoid a number of problems that are caused by low light levels.

Leggy tomato plants
Sowing too early means that plants struggle through shorter days, and in their search for more light, become leggy.

Leggy tomato plants with thin stems will produce fewer tomatoes, so it's important to grow healthy stocky seedlings and young plants if you want a good crop.

Fewer flower buds
The other issue with low light levels is the amount of flower buds that are encouraged by light. Less light means fewer flowers and eventually tomatoes.

In conclusion
It is true that a plant sown a little later in the spring can catch up and do better than a plant sown earlier that has had to struggle through short days and cooler temperatures.

Of course, with grow lights and correct temperatures, tomatoes can be sown and grown any time of the year!
