I don’t know about you, but don’t watermelons tend to conjure up images of holidays to Spain or Greece. That's where watermelon stalls provide welcome relief on the side of a hot and dusty road! Juicy, nutritious and refreshing, there remains something slightly exotic about them and perhaps they’re a rare treat that you’ve only ever tried while abroad, or once in a while from a supermarket. But have you ever thought about growing your own watermelons here in the UK?
In fact watermelons are believed to have originated in Africa where growing conditions are ideal for them to thrive in the wild. Yes, they do need warm and sunny conditions in order to well. But that doesn’t make them impossible to grow in the UK and once they get started, they are in fact relatively maintenance free.

Spend a little time choosing a watermelon variety that will be most suited to the conditions where you live. We do occasionally have very hot summers, but let’s face it, not that often, so be realistic. There are some varieties that perform ok in cooler climes.
Your watermelons are going to need well drained soil with a pH of about 5.5 to 7, a well prepared spot and lots and lots of sunshine. You will not be able to grow them outside until the ground is warm (at least 60-70 degrees) and as always you’ll need to prepare the soil well in advance by digging in lots of good compost and organic matter.
As an easier alternative you might want to consider growing them in growbags and containers in your greenhouse or under a cloche but just always bear in mind, that they will not thrive if it’s cold and they will need lots of sunshine. If you want to eventually plant out, start them off indoors in containers in late spring and don’t plant out until June and well after the last frost.
Plant your watermelon seeds about 6 cm deep and then watch the magic happen. They are part of the vine family and so they’ll grow vigorous vine type leaves. Unless you want to support and net your watermelons (and remember that will mean supporting the growing fruit too), it is best to leave them sprawling on the ground or around the container or grow bag.
They’ll need about 3 foot each to spread out and make sure you continue to keep them covered at night once outside until July.

Water them well but make sure you allow them to drain properly between waterings. If it turns out the summer isn’t all that you hoped for in terms of long sunny days, then give your melons a helping hand. Put them under a cloche, wrap them in a fleece or perhaps move them back into the greenhouse.
Towards the end of the summer, as the watermelons swell, gently tap the side and if they sound hollow, they’re ready to harvest. Just cut them off at the stems and if you’re lucky you should get about two watermelons per plant. Enjoy your melons and as they are annuals, don’t forget to save the seeds for next year’s planting.
China is the largest producer of watermelons in the world and in 2012 produced 70,000,000 tonnes of them!
Watermelon seeds were found in the tomb of the pharaoh Tutankhamun and so can be dated back to the Egyptians if not even earlier.
The rind of the watermelon is edible if not very tasty! In some parts of the world they pickle it, fry it and stew it because it’s very nutritious!
