Is it neccessary to mulch my watermelon beds or can I plant the seeds without it. I live in North West

Watermelons thrive with plenty of old manure and a good water supply. Mulch will help to retain water and keep the roots cooler.

What kind of manure or fertilizer is good for watermelon in Durban, south africa

Watermelons are like pumpkins and do well with plenty of manure and water. Before you plant them dig a hole as deep as you can without going into the hard clay. Put some old newspapers or denim jeans in the bottom of the hole and then add as much old rotted animal manure and household scraps into the hole. Cover the hole in the the topsoil leaving a mound. When it is time to plant the seeds in the mound and give them a good watering. Your watermelons will grow well and the newspaper or old jeans will help hold water.

I planted seeds about September 2016, and we live in Mpumalanga , Witbank. The first melons are forming, we have had good rain fall this year, I am just starting out farming, and am proud to say to see that all my crops of all types of vegetables have bared fruit and vegetables in such a short time. I am planning to do a larger quantity and the water outside our place never dries up, what do I do to improve my crops. I hope that my request will get help with regards to the water issue, water lies daily on the surface, we are not sure if there is a bore hole. Thank you Hermann Jacques Keyser.

It is great to see your enthusiasm for growing food. The four needs of all living things are Sunshine, Food, Water and Care. Sunshine is free so we need to provide the other three. Adding old manure in the Autumn, providing consistent water and mulching in the summer to conserve water and help control weeds will all help produce good crops. The other things are - planting the right variety for the time of the year and removing weeds which use the food and water in the soil. If you look up the Dept of Agriculture or Primary Industries in the internet they will have people or Information Sheets thet will help. All the best with your plans.

If you do not have access to cow manure, but nitrogen rich fertilizers or otherwise, pour a mixture of 2 water and 1 urine on the plan roots...it has worked for me for more than five years
