How to grow squash. Mine are only about 3 to 4 cm, although there are several on the bush they don't get any larger. If left on bush they rot. I cut off the leaves with the mildew to let the sun in to the fruit. Jan

Answer: Hi Jan

Squash is a warm season crop and requires thorough soil preparation with organic matter and pre-planting fertiliser which will see the plants through to flowering. After flowering commences, scatter a mixed fertiliser around the base of the plants. Repeat this side-dressing at 4-5 weekly intervals while plants are bearing.

The button squash are best harvested when they are 5-10 cm in diameter. They will crop over a long period of time so make sure you keep up the fertiliser to encourage more flowers, hence, more squash.

Powdery mildew is a problem on cucurbits so it is important to give your plants plenty of sunshine and water the ground around the plants rather than the leaves to prevent this disease from taking hold. Mancozeb is registered for use on cucurbits to control powdery mildew. Any infected leaves that have fallen on the ground should be picked up to limit spread of disease.
