Yellowing leaves are a sign of nitrogen deficiency. Fertilize with cow manure. If your watermelon plant has yellow leaves and the fruits are beginning to rot, Southern blight may be to blame. There is nothing you can do for Fusarium Wilt but remove the plant from the garden.

The soil here is extremely sandy so we make compost and loosen the soil (basically make a hole for seedlings and enrich it with 300ml of compost). I've never planted watermelons and would like to (cabbage and radish work wonderfully here). What irrigation is better - overhead or drip? How much water per day/week? (we plant without wastage). Is it okay if I use mulch - we do it for everything else to preserve the soil. It gets to about 45C in summer... is that okay?
