I’m using RootGrow - a Mycorrhizal fungi to help the roots and whips grow.
RootGrow - a Mycorrhizal fungi is a once-only treatment that increases the volume of soil explored by the plant by up to 700 times! RootGrow - a Mycorrhizal fungi acts like a permanent fertiliser and ensures rapid establishment BUT does more than a fertiliser in that you can expect healthier plants because the friendly Mycorrhizal Fungi help plants have better growth, vigor, flowering and long term survival via this balanced nutrition system. For a healthier plant anywhere in the garden (beds, borders or hanging basket) or trees - indoors or outdoors, choose from our low cost rootgrow range with the friendly fungi!
Once the RootGrow - a Mycorrhizal fungi is mixed, then we planted the whips.
Still have some more todo, when the weather gets warmer and better!
