The watermelon in my garden is growing extremely slow. I planted the seeds a month ago and now only have small sprouts with a few leaves on each plant. it has been very warm here and we have had quite a bit of rain but everything else in my garden is more or less thriving. does anyone know why my watermelon may be growing so slow and what i can do to speed up growth?

thanks

Where are you located? It would help to know your zone and conditions.

Cucurbits (family including melons, cucumbers and squash/pumpkins) all tend to start slow but once they take off, look out! You can almost watch them grow and they will take over an area fast.

Make sure it has plenty of water and sunshine – they like full sun and good airflow.

Welcome to the Organic Gardening Forum. I can't help much with watermelons because they won't grow here where I live, but I would urge you to add some information to your profile that will help us help you. In the location field, please tell us your USDA climate zone if you know it, and your general geographic location. See the information as it appears in my post for example.

The bug problems you mentioned in your other post and the uneven results you are having with your plants suggest that your soil is not yet in good health. Building soil health is a process that takes a while. It will involve adding organic materials and possibly other soil amendments until your soil has a good mix of mineral and organic components, and beneficial soil critters.

Compost and mulch are almost always necessary additions to your soil, but to be sure, you should contact your state university's agricultural extension department. They will almost certainly have a website that will tell you how to submit a sample of your soil for testing. The results of your soil test will guide you as you build better soil.

Further to your bug problems, organic gardeners try to avoid even the so called "safe" and "organic" pesticides because they indiscriminately kill both the pest insects and also the beneficial insects. You know about the bees, but there are others that feed on the pest insects and they usually arrive shortly after the pests. In a healthy garden the pests and their predators generally maintain a balance that minimizes damage to your plants.

Part of organic gardening is discovering plants that are more attractive to pests than the vegetables you are growing, and that can withstand the pest damage. For example, this year I learned that the grasshoppers that invaded my greenhouse really like bolted spinach and radish leaves where they do no damage and are easily spotted so that I can vacuum them up with my shop vac.

Hello and welcome. I find that watermelons don't really take off until the temps have been consistently high and then, like Matt said above, they can grow up to a foot a day. Mine have yet to put out a lot of vines but I have several melons already due to the week of extremely hot and humid weather we recently experienced.
Good luck.

I always figure that cukes take off the first of July, and watermelon take off the 1st of August. Before that you can use the space around them for lettuce or spinach or radishes. Something that grows quick, and is done when melons and cukes start taking up space.

However, do not plant too close to the melon or cukes. Mrs.K
