Some of the properties good potting soils have are as follows:
balanced nutrient contents and low salinity levels to encourage the development of healthy and long-lived plants
an optimal pH level adjusted to the plants’ requirements
a good structure that ensures high water holding and drainage capacities to prevent the plants from dying from lack or excess of water, depending on water supply
substantial absence of weed and plant-damaging substances.
For natural protection: bark mulch
For ideal production, spread a layer, up to approximately 5 cm thick, of bark mulch over a weed-free surface.
Bark mulch is available in different particle sizes – fine, medium and coarse.
Fine bark mulch should be used for roses. It can be used for mounding up and then spread over the entire flower bed in spring.
Medium to coarse mulch should be used for trees and shrubs.
