The Best Time and Method for Propagating Podocarpus by Cuttings: A Detailed Guide

Podocarpus (Podocarpus macrophyllus) is a rather precious ornamental tree for courtyards and also an excellent material for stump bonsai, but its seed sources are scarce and its growth is slow. It sets seed slowly, and seed propagation is slow. Therefore, to speed up its propagation rate, many people choose cutting propagation. Let's learn about podocarpus cutting propagation together with the editor below.

1. Cutting Time

Podocarpus cuttings can be taken in both spring and autumn. In southern regions, spring from April to May is suitable, and autumn from September to October is suitable. Before taking cuttings, prepare the materials needed for cutting in advance: a knife, branches, cutting soil, a cutting pot, clean water, a spray bottle, rooting hormone and other materials. These are all needed for podocarpus cuttings.

2. Preparing the Pot and Soil

For the soil used to root podocarpus cuttings, you can use coarse river sand directly, or mix garden soil with river sand to make a growing medium; make sure the soil is loose and has excellent drainage. Before cutting, the soil needs to be disinfected, for example by exposing it to the sun or disinfecting it with a disinfectant. The pot for podocarpus cuttings can be somewhat larger; if you are taking many cuttings, choose a larger pot.

3. Selecting the Cuttings

For podocarpus cuttings, choose semi-lignified young shoots, or you can choose thick, sturdy old branches, depending on the actual situation, but the branches chosen must be robust and free of pests and diseases. After selecting the branch, cut it off and keep the wound smooth; it is recommended to cut the base of the branch at a 45-degree angle, and at the same time remove the leaves at the base of the branch so that it can be inserted into the soil easily. To help the cuttings root as quickly as possible, before planting you can soak the podocarpus cuttings in a rooting solution for 2-3 hours, which helps the cuttings root.

4. Taking the Cuttings

The cutting process for podocarpus is not complicated. Put the prepared soil into the cutting container, keeping the surface level, then spray a little water on the soil to keep it moist. Next, insert the podocarpus cuttings directly into it, keeping a spacing of about 3-5 cm between branches and inserting them to a depth of 3-5 cm, and press the surrounding soil firm. After cutting, water thoroughly once, then place it in a ventilated, shady spot for care. After cutting, keep the environment sufficiently humid, water and mist frequently, and control the air humidity at around 80%. Generally, they will root and sprout in 30-40 days.
