Q.
Hi Tui, the lower tomato leaves are turning yellow and brown. The temperature has increased quite rapidly, could this be the cause? Can you help?

Hi Rose, it could be a combination of the hot weather, your plants could have powdery mildew or the leaves are naturally aging and yellowing as the plants grow. The lower leaves can be removed up to the first couple of trusses of fruit to help improve air circulation around your plants. Make sure you keep the water up to your plants in hot weather, you may need to water twice a day in the morning and evening, and adjust watering when temperatures cool. Mulching around your plants will help conserve soil moisture and regular applications of Tui Organic Seaweed Plant Tonic to help stimulate growth, seaweed plant tonic also help plants tolerate temperature extremes - hot and cold.

The lower leaves on my tomatoes are turning yellow and brown. What do I do? Comments
Hi there, my golden queen peaches were attacked by some sort of fruit fly. Every peach was infected with worms and the flesh around the seed has rotted. How can I get rid of them please.

Hi Hazel, this is likely caused by fruit worm caterpillar which overwinter in the soil or in the bark of the tree. They are hard to spray as the caterpillar is inside the fruit which is what is causing the brown centre around the stone. Prevention is the best cure. Maintain a winter spray programme using a spraying oil to control overwintering larvae. Pick up any fallen fruit, prunings and fallen foliage from around the tree, dispose of in the rubbish rather than leaving on the ground under the tree or composting as this gives the caterpillar somewhere to overwinter and the lifecycle will continue. Talk to your local garden centre about a suitable insecticide, if spraying insecticides, timing is very important, the young larvae need to be caught before they enter the fruit.
