Use It As Compost Fertilizer

Tips To Keep In Mind While Making The Compost

Unless the compost is precisely made, your fiddle leaf fig might not be able to absorb all the benefits that the coffee has to serve. So, make sure you follow the below-enlisted tips while preparing it:

The compost should not be runny in consistency. It must be dry and lightweight.
To dilute the nitrogen presence, add sticks, bark, and dried leaves to the coffee grounds.
Do not overdo the compost, else it might show adverse effects on your houseplant.
Since the compost already retains water, you must not add any extra water to it.

Liquid Fertilizer

Another great way of adding coffee grounds to your fiddle baby is in the form of liquid fertilizer. Instead of adding coffee directly, make a fine liquor using coffee and water, and leave it for one to two weeks. Do not forget to stir your liquid fertilizer every two to three days. After the coffee breaks down, refine it and add it to your fiddle leaf fig plant. Doing this frequently can harm your plant and damage its roots. However, make sure to observe the results, and continue the process only if your plant responds well. While preparing your liquid fertilizer, make sure there is no cream or sugar in it.
