What Fertilizer Do I Use on Avocado Trees

Avocados need nitrogen, first and foremost, and a little zinc. You can use a citrus tree fertilizer as an avocado fertilizer or go organic and use compost, coffee, fish emulsion, etc. Avocados are hardy in USDA zones 9b to 11 and in those regions soil is generally sufficiently nutrient rich to support an avocado.

When should I fertilize my avocado tree?

If you need to apply fertiliser or manure before planting, do so 6 months before so it’s broken down and taken up by the soil before planting. These fertilisers pose less risk to tree roots. You should never use nitrogen, potassium or animal manures on or just before planting.

Is blood and bone good for avocado trees?

Planting Notes: Plant in spring to early summer. Soils that call for additions such as gypsum, lime, sand etc. to improve the drainage are generally not suitable for avocados. … Applications of lime / dolomite / rock phosphate and blood and bone are also beneficial depending on the natural soil nutrient level.
