My tomatoes' new leaves were almost white and stunted. Leaves burnt off,new leaves are green but still stunted

However, the plants are full of flowers and fruit, and some of the plants have new normal leaves. I added boron to the soil as advised on the radio. I have this problem most times I grow tomatoes. I also try to pick a different spot in the garden each time.

Answer: Hi Marie,
There is a viral disease called Tomato Yellow Top. The virus is spread by the potato aphid and by the green peach aphid.

Infected plants are stunted, the leaves appear stiff and upright and markedly chlorotic. The leaf size is reduced and the margins of the leaf tend to curl downwards. Often flowers fail to set fruit and the flower buds can be killed following infection. It can affect the yield if plants are infected in the early stages. Fortunately no symptoms are produced in the fruit.

It is important to keep your plants free of insect attack in early stages. Monitor them daily and if you see any aphids present on your tomato bush, spray with a product called Nature’s Way Insect & Mite Killer to control these sap sucking insects.

Keep your tomato bushes well watered and fertilised with Yates Thrive Concentrate Tomato Food on a weekly basis. This product is high in potassium to stimulate fruiting.

It is always a good idea to do a crop rotation. I am sure at this stage if you continue to monitor your plants and give them the correct nutrients they need, you will still be able to harvest a good crop of tomatoes.
