Grass Clippings

Many people wonder what to do with grass clippings. One of the best uses is as tomato mulch. Be careful, though, as a few rules apply. First, you need to let the grass clippings dry out for two or three days. And, second, it is better to mix them with carbon-rich mulch before using. Straw will do just fine. But why? Because straw is too rich in nitrogen and can burn roots.


Mulching the tomatoes with compost is a great idea, but you need to have plenty of it. Have you got any? Then don’t hesitate! Rich in nutrients, compost will boost the growth, fruiting and taste of your tomatoes.


In addition to decomposing quickly, hay also offers an excellent carbon to nitrogen ratio, which is good for tomatoes.

Dead Leaves

Dead leaves make good mulch for tomatoes and are easy to store. Put them in a corner of the garden and use them in the summer. Choose leaves from ash or fruit trees for their good carbon/nitrogen ratio. On the other hand, avoid those of oak and plane tree, because they have high carbon content.

Hemp Mulch for Tomatoes

Also called flax chaff, hemp mulch is recognized in organic farming and is highly effective in protecting the roots of your tomatoes from all temperatures. This organic matter is biodegradable and provides the soil with several nutrients while improving its quality. Spread it in a layer of between 2-4 inches/6-10 cm. Hemp mulch for tomatoes is quite light and you need to water it to stabilize it. That said, it’s best to avoid it in windy areas.

Cocoa Bean Shells
