Indoor Plant Fertilisers

FAQ

Which fertilizer is best for indoor plants?

The best fertilizer for indoor plants largely depends on the specific needs of the plants you're growing. However, a balanced, water-soluble or liquid fertilizer is often a good choice for a broad range of indoor plants. Specialized indoor plant fertilizers that contain a balanced ratio of the essential nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—are generally recommended. You can also find formulations with added micronutrients like calcium and magnesium for specific plant needs. Organic options like fish emulsion or seaweed extract can also be beneficial.  

Do indoor plants need fertilizer?

Yes, indoor plants do benefit from regular fertilization, but they typically require less frequent feeding compared to outdoor plants due to their slower growth rates and the more controlled indoor environment. Over-fertilizing can lead to nutrient imbalances, so it's important to follow the manufacturer's guidelines for application. Fertilizing is especially beneficial during the growing season (spring and summer), while most indoor plants require less to no fertilizer during their dormant period in the fall and winter.   Remember to always follow manufacturer guidelines or consult with a horticultural expert for your specific indoor plants' needs.  

Top tips for looking after your indoor plants

 

1. Right Light: Understand the light requirements of your plants. Some need bright, indirect light, while others thrive in lower light conditions. Position them accordingly.
2. Water Wisely: Overwatering is a common mistake. Use a watering schedule tailored to each plant's needs and consider using a moisture meter to avoid overwatering.
3. Humidity Levels: Some indoor plants, particularly tropical varieties, thrive in higher humidity. Consider using a humidifier or placing a water-filled tray near the plant.
4. Fertilize Carefully: Use specialized indoor plant fertilizers and follow manufacturer guidelines. Over-fertilizing can harm your plants.
5. Regular Cleaning: Wipe the leaves with a damp cloth to remove dust, which can block sunlight and reduce the plant’s ability to photosynthesize.
6. Proper Drainage: Make sure your pots have drainage holes to prevent root rot. If using a decorative outer pot, ensure it doesn't trap excess water.
7. Temperature Control: Keep plants away from hot or cold drafts, radiators, and air conditioners. Most indoor plants prefer a consistent temperature.
8. Pest Check: Inspect your plants regularly for signs of pests like spider mites or aphids and treat as necessary.
9. Repotting: As plants grow, they may outgrow their pots. Repot your plants every couple of years or when you see signs of root crowding.
10. Pruning and Deadheading: Regularly remove dead leaves and spent blooms to encourage new growth. Some plants may also benefit from periodic pruning to maintain their shape.
