Within the UK and Ireland there are a wide range of trees grown within nursery stock production in varying species and sizes. From small trees for garden centres in 10-15 litre pots up to Semi Mature Trees in 200 litre up to 1000 litre pots. Trees are potted up bare root trees lifted from the field. Larger specimens may be rootballs.
Maintaining the nutrient supply to large trees, and ensuring trace elements, such as iron are constantly available for best foliage colour. High levels of nitrogen can lead to soft growth which can be damaged in high winds.
Using Osmocote Exact Standard gives your trees the best nutrition package in this environment and will help provide great quality trees. The nutrient release matches the trees demands and ensures balanced growth which ensure the trees establish better when eventually planted out.
Varies depending on species, generally 4 - 7kg.
For pot sizes over 20 litres consult your ICL Specialist who will be able to advise nutritional programmes taking into account all plants needs as well as background nutrient supply.
