Solid fertilisers for foliage plants: read the instructions

Choose a solid fertiliser by its formulation and intended use, not just its form. Follow the dosage specified for the product and growing volume.

Granules, sticks and other formats

Check whether the product promises gradual release, where it should be placed and how often to use it. Do not generalise a duration across brands or assume that a natural product can be used without measuring.

Consider the substrate

Record nutrients already in the mix and products used recently. Adding solid fertiliser as well as liquid may lead to an unintended combined dose. The liquid versus solid guide distinguishes useful checks.

Choose for a foliage plant

Compare fertilisers for houseplants with the selection and dosage method. If your plant shows symptoms, first read the deficiency-checking guide.
