Can I plant grevilleas in Osmocote Premium Potting Mix?
No. Because all the Osmocote potting mixes contain Osmocote Exact, phosphorus- sensitive plants such as grevilleas, banksias, hakeas, proteas, waratahs, etc may be adversely affected. Instead, for these plants, choose a mix that has no added fertiliser and enrich it with Osmocote PLUS Native Gardens.
