Have you chosen the right varieties?

Tomatoes come in many different varieties, the bulk of which can be divided into three categories, namely field, garden and greenhouse tomatoes. Your disappointment in the growth of the tomatoes you planted could be as a result of growing a garden or field tomato in a greenhouse. They each have different requirements to those tomatoes suited to growth in a greenhouse, so it might very well be a simple case of not supplying them with the right nutrients or sunlight levels.

Have you allowed for air movement?

Tomatoes planted too close to each other are prone to developing problems with their foliage, like the formation of grey mould, leaf spots, early blight and even dying or yellowing of the leaves. Lack of air movement is often the cause of many of these foliar diseases, caused by the subsequent build-up of humidity.

Make sure they’re correctly spaced out when planting. This could mean you might not be able to fit as many plants into the space, but at the end of the day the plants you do manage to grow will be more fruitful and grow stronger, providing a greater overall yield. Fewer plants also come with reduced maintenance, which comes in very useful if you have multiple vegetables across which to split your time.

Have you rotated your plants?

The rotation of your crops is important following each growing season. If the location of your tomatoes hasn’t been changed from the previous year, they could be suffering from a lack of nutrients. Rotation reduces the chances of soil deficiencies as different plants require more or less nutrients than others.

If you use grow bags in your greenhouse, this issue can be avoided completely. Grow bags make sure of the delivery of the required amount of nutrients to your tomatoes.

Don’t lose hope and give up on your tomatoes. Simply get savvy in the garden and follow these tips to enjoy tasty bumper crops this year.
