Once digested, it turns into a reservoir of energy that doubles the yield. In our article of the day, we will tell you about these few foolproof ways of using rice to have lots of courgettes this summer. So, give it a try!
Place the rice at the foot of the courgettes
To put this method into practice, nothing could be easier. It is enough to take a few spoons of rice grains, find them in the pantry, bury them at the foot of the zucchini and then water. Once in contact with water, the starch comes out providing energy to the courgettes or houseplants. Yes, you can also put rice in your flower pots. In addition to being an excellent fertilizer, rice also promotes drainage. Be careful, however, we remind you that it is a slow-release natural fertilizer. This method should therefore be performed once every two months, at most.

To enjoy rice as a quick-release natural fertilizer, consider rice water. To increase your cucurbits, use it once every 2-3 weeks. How to prepare it? There are a few options for getting the most out of it in the vegetable garden.

Of course, you can remove the activated charcoal and simply ferment the rice grains in a good amount of water. That’s how!
