Zucchini Leaves Going Yellow From Centre
This is our second lot of zucchini plants this year. The plant starts to grow and look healthy, then the new leaves from the centre of the plant start to turn yellow. We have completely dug up the garden, put heaps of lime, dianamic lifter, compost, and other fertilizer in before replanting, but the same thing is happening. Anybody got any suggestions?
