Indoor Plant Fertilisers

Indoor plant fertilisers are specially designed to provide gentle, balanced nutrition for houseplants growing in containers with limited soil. Unlike outdoor fertilizers, these formulas are less concentrated to prevent root burn, often come in liquid form for easy absorption, and include essential micronutrients tailored for indoor plants. They also offer balanced NPK ratios for healthy foliage and flowering, with a gradual nutrient release for consistent feeding.

Do indoor plants need fertilizer?

Yes, regular fertilization is beneficial for indoor plants. However, they require less frequent feeding compared to outdoor plants due to slower growth rates and a controlled environment. Fertilizing is particularly important during the growing season (spring and summer), while most indoor plants need little to no fertilizer during their dormant period in fall and winter. Over-fertilization can cause nutrient imbalances, so it’s essential to follow the manufacturer’s instructions or seek advice from a horticultural expert.  

Which fertilizer is best for indoor plants?

The ideal fertilizer for indoor plants depends on the specific needs of your plants. A balanced, water-soluble, or liquid fertilizer is typically a great choice for a wide variety of houseplants. Look for specialized indoor plant fertilizers with a balanced ratio of essential nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—along with added micronutrients like calcium and magnesium. Organic options, such as fish emulsion or seaweed extract, can also provide excellent results, especially for those seeking eco-friendly alternatives. View our full range of NPK Fertilisers
