Plants get energy from the photosynthesis process, but plant food (fertiliser) provides additional nutrients that can keep your plant strong and healthy.
To stay in the best health, plants benefit from nutrients, principally nitrogen, phosphorus and potassium. Over time potted plants will use up the nutrients in their potting soil and therefore, it is beneficial to top-up these nutrients using fertiliser.
There are different types of fertiliser suitable for different plants. The most suitable fertiliser for the majority of indoor plants is a balanced liquid fertiliser, which will sometimes need to be diluted to half strength. In general, your plant will only require fertiliser during the growing season (Sprint to Autumn). We have specific care instructions for every plant on its product page.
- Plants need feeding when they are growing, so more in Spring, less in Winter
- Plants that grow more quickly need feeding more frequently and slow-growing plants (e.g. Cactus) less frequently
- Water your plant thoroughly a few days before adding fertiliser, as your plant will absorb nutrients through its roots, so moist soil will help spread the fertiliser
- As with many areas of plant care, it is better to be too cautious than too bold with fertilising your plant, so it is often best to half dilute fertiliser before feeding your plant
- Flowering plants will need fertilising more frequently
