Acacia pravissima is a woody shrub/ tree that grows up to 4m in height, it does well on heavy clay soils and is great for a subtropical forest garden situation. it is light and airy and can easily grow anywhere around heavy feeders, fix nitrogen, be chopped and dropped and also have flowers that feed the native and other beneficial insects, in particular some of the psyllids that we need! They handle a light frost but do not like heavy frosts so not an option in cold climates.
Forest Gardens are orchards designed in such a way so the needs of the heavy bearing heavy feeding fruit trees are taken care of in the design.
We do this by:
- Ensuring no more than 60% of the canopy space is taken up by heavy feeders. We prefer 40%.
- For every square metre of heavy feeder canopy there is 0.8 of a square metre of nitrogen fixer.
- For every square metre of heavy feeder there is 1 comfrey plant.
- You have all seven (7) layers of the forest garden present.
- You have as wide a range of mineral accumulators present.
