Propagating plants by cuttings 101
Should I use softwood, semi-hardwood or hardwood cuttings and when?
Propagating plants at home with cuttings is relatively easy and in this time of climate change we need all the plants we can get. It is also quite satisfying being able to say I propagated it myself. The time of year of taking cuttings and the species are both important factors. Some species don’t strike readily from cuttings and seed is needed.
Cuttings are pieces of plants made to form roots, and when they do grow roots, they are said to strike. The cutting when placed in propagating sand should form a callus on the cut end and then grow roots from the callus. Striking roots may take a few weeks to a few months.
This article will cover the soil or propagating sand to use; the moisture and temperature; tools; cutting material; the types of cuttings and timing; and some species of plants suitable for cutting propagation.
A propagating sand for use in containers needs to be a clean, coarse grained, sharp sand. Sharp meaning each grain of sand is angular in shape, not round, reducing the tendency to pack together. Good drainage resulting from large pore spaces is required, this allows for more aerated soils which are less suitable for fungal growth.
