Compost is much better than fertiliser for melons, marrows and cucurbits. Fertiliser actually depletes the soil of life and is generally over applied to veggie beds and either stunts plants or burns by trying to force them too much. Your edible plants will always flourish in good quality compost, especially water melons.

Our watermelons get to the size of rockmelons then go yellow and get no bigger, what's the problem? How many should we have on the one vine please? JJ

I am growing a variety of watermelon called "red rocket". These are supposed to be, according to the tag, large oblong-shaped with a high yield, however, the only 2 fruit I have growing are just the size of small rockmelons and appear to have stopped growing. The oldest of these 2 is about 5 weeks now. Are my expectations of what is called large fruit and high yield too high, or do I need to do something to help them along. I have recently used Dynamic Lifter For Fruit and Citrus in the patch but am unsure if this will help. The other problem is that, although the plant is very vigorous and has plenty of flowers, it doesn't seem to fruit, even though I've used the brush trick to help pollinate. The only thing I can think of is that it doesn't get a lot of sun, but if this was the problem would that not also affect the quantity of flowers and health of the vine?

hello, last year 2019 i grew red rocket melons, i got melons up to 17 kg, grew in part shade up to full sun, they simply need full sun and heat, even under 30% shade cloth no good, heaps of flowers and melons, plus grow other plants that give you more flowers for pollination and bees, even ants will pollinate, happy growing

our plants are growing everywhere but now some leaves have gone lighter in colour. What does this mean?

You need to cut back your plant so you get less fruit and more growth to the fruit, this will give the plant a boost. the cutting back should be done when the flowers come on the vine.

YES A BIG YES this comes from a grower once they start to set fruit they need water
