Can I use Osmocote in conjunction with liquid fertiliser?
Yes. While Osmocote steadily provides all of the plants’ nutritional needs, you can also give them a quick boost with an occasional foliar fertilising using a liquid fertiliser such as Miracle-Gro All Purpose Water Soluble Plant Food. For Australian native plants you can use Miracle-Gro Water Soluble Azaleas, Camellias and Rhododendrons Plant Food and for vegetables, Miracle-Gro Water Soluble Tomato Plant food is excellent.
