It's time to fertilise your garden. But why fertilise? What type should you use, and how? These are important questions, as proper fertilizer use directly affects plant vitality. Plants need extra nutrition to thrive through all growth stages, from budding to fruit production. They exhaust soil nutrients and need energy for strong roots, leaves, and photosynthesis. Fertilizers provide this essential support.
When to know it’s time to fertilise garden plants
Fertiliser isn't about keeping plants alive—it's about helping them thrive. Think of it as a boost for growth and overall plant health.
-
Healthy soil often provides all the nutrients plants need. If you've mulched and cared for your soil, you might not need additional fertiliser.
-
While garden beds may thrive with minimal fertilisation, container plants need consistent feeding due to their limited soil access.
-
Start fertilising your plants in spring as they awaken and begin actively growing. Continue throughout the summer, but stop as they wind down for the dormant season.
-
While trees and shrubs often thrive without fertiliser, you can give them a boost with a yearly application in early spring if needed. Fertilisers are primarily used for plants that require more nutrients, such as fruits, vegetables, and bedding plants.
What fertilisers to use
Nourish your soil with a variety of organic fertilisers like garden compost, well-rotted manure, mushroom compost, and seaweed.
-
Synthetic fertilisers offer a concentrated dose of nutrients, delivering a potent boost to plant growth. They come in various forms, including pellets, granules, powders, and liquids.
-
Controlled-release fertilisers use a clever coating to provide a steady supply of nutrients. The porous granules allow water in, triggering a gradual release of fertilizer into the soil over time.
-
For a natural and sustainable approach, choose slow-release organic fertilisers. These break down gradually, providing a continuous source of nutrients for your plants.
Explore the world of liquid fertilisers! You can purchase seaweed or plant-based concentrates to mix with water, or create your own using comfrey or nettles steeped in water.
How to apply fertilisers
- Read the label: Instructions vary for different fertilizers.
- Dilute if needed: Some fertilizers require dilution before use.
- Apply as directed: Follow the instructions for soil application or direct application.
- Use responsibly: Never overuse fertilizer.
- Choose safe products: Ensure your fertilizer is safe for wildlife, pets, and children.
