If you want to put gravel to work with your potted plants, use it outside the pot. Put a layer of gravel in your plant’s drainage tray, or down inside a decorative planter, then sit your plant pot on top. The gravel will hold water and increase humidity, while keeping your plant’s roots up out of the puddle.
Similarly, can I put decorative stones around plants?
As stated previously, using decorative stones on top of soil prevents plant roots from being over-exposed to the sun as well as stopping weeds from growing. This is one of the main reasons why it is so common to see rocks on top of soil as it is a very effective way to keep your plants healthier for longer.
In this way, do I need gravel in my plant pots?
In general, it’s not necessary to put rocks in the bottom of plant pots. One rock to cover the drainage hole is enough – just enough so that the soil doesn’t leach out of the bottom but water can flow freely through the pot. Putting rocks in plant pots doesn’t aid drainage or improve air circulation.
Are decorative rocks bad for plants?
Adding rocks to topsoil prevents water loss by shading the soil and reducing the temperature below it. As a result, less water evaporates out of the atmosphere. Additionally, the rocks prevent drafty winds from removing water out from the soil as it acts as a shield when it coats the top layer.
Pea gravel is generally more expensive than organic mulches and, because of its weight, it is more difficult to install. … Your soil may retain moisture better with pea gravel than with no mulch at all, but the rock is not effective in maintaining even soil temperatures.
Including a permeable membrane between the base of the trench and the top layer of gravel is highly recommended. A membrane will ensure the gravel does not mix in with the base layer of hardcore or the soil beneath, and is also a strong, permeable and will prevent weeds from sprouting through your gravel.
