Why do plants need food?
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.
What type of food do plants need?
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 (Spring to Autumn). We have specific care instructions for every plant on its product page.
- Plants need feeding when they are growing, so typically in Spring and Summer
- Plants that grow more quickly need feeding more frequently while slow-growing plants (e.g. Cactus) need feeding less often
- 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 overly cautious than too bold with fertilising your plant, so it is often best to dilute your plant feed by twice the amount the bottle recommends before feeding your plant
- Flowering plants will need fertilising more frequently
