Rose is only going to thrive and produce masses of flowers if it has a happy root system and the best way to do this is to create a living soil profile.
I hear you ask what is a LIVING SOIL PROFILE, well the best way to explain it is to imaging the floor of an Amazon rain forest which is alive with fungi and microorganism which help break down any depries which fall on to the forest floor i.e leaves, branches and even trees. The resulting compost is nutrient rich and provides the forest plants and trees with all the minerals and nutrients they need to thrive
So how do we replicate this and no we do not have to plant a Amazon rain forest. The secret is in the two layered mulching process.
