Frequently Asked Questions

AI
Apply fertiliser in early spring as new growth appears and again in early summer after the first flush of blooms. Stop feeding by late summer to allow wood to harden before winter.
Organic options improve soil structure over time and release nutrients slowly, while chemical feeds offer immediate results. Choose organic for long-term soil health, or synthetic for quick nutrient boosts.
Liquid feeds are typically applied every two weeks during the growing season. Granular or slow-release fertilisers usually require application every four to six weeks, depending on the product instructions.
