How to Grow Australian Tea Trees (Leptospermum laevigatum)
Fertilize A Leptospermum Laevigatum Australian Tea Tree
Choose a granular balanced fertilizer, such as 15-15-15. Fertilizer for blooming plants, such as a 7-9-5 mix, also is a good choice for Australian tea trees and is preferable if your soil is lower in phosphorus than potassium. Mix thoroughly until the fertilizer is dissolved completely. Water the tree thoroughly with the water and fertilizer mix. Saturate the ground under outdoor plants from trunk to drip line.
