Growing tomatoes in greenhouses can deliver bumper crops — but only if you use the right techniques. Even with the best will in the world, sometimes our tomato plants can fail to deliver the results we’re looking for.
Rather than giving up your hopes of red, ripe, tasty tomatoes, you might just need to make a few simple changes. Here, grow bag retailer, Compost Direct, share the three things that could be stopping your tomatoes from growing in your greenhouse.
Have you chosen the right varieties?
There are many varieties of tomatoes out there, a lot of which are divided into field, garden and greenhouse categories. If you’re disappointed with the growth of the tomatoes you’ve planted, it could be because you’re growing a field or garden tomato in a greenhouse. These have different requirements to tomatoes that are suited to growing in greenhouses, so it could simply be a case that you’re not supplying them with the right level of sunlight or nutrients.
Have you allowed for air movement?
If your tomatoes are planted too close together, you may spot problems with their foliage. For example, grey mould, early blight and leaf spot are common, as well as dying or yellowing leaves. The cause of many of these foliar diseases is a lack of air movement, caused by a build-up of humidity.
When planting, make sure they’re correctly spaced out. You may not be able to fit as many plants into the space, but ultimately the plants you do grow will grow stronger and be more fruitful, providing you with a greater overall yield. Fewer plants also means reduced maintenance, which will be useful if you’re splitting your time across multiple vegetables.
Have you rotated your plants?
Rotating your crops is important after each growing season. If you haven’t changed the location of your tomatoes from the previous year, they could be suffering from a lack of nutrients. Different plants need more or less nutrients than others, so rotating reduces the chances of soil deficiencies.
You can avoid this issue completely by using grow bags in your greenhouse, which will deliver the nutrients your tomatoes require.
Don’t give up hope on your tomatoes. By getting savvy in the garden and following our tips, you can enjoy tasty bumper crops this year.
