Propagating standard roses is an extremely valuable skill that any horticulturalist or hobbyist can master. Before we get into the details of propagation, lets have a quick recap on the botany of a standard rose.
The rose can be divided into 2 parts: the lower part is called the rootstock, and the upper part is called the scion. As the name suggests, the rootstock contains the root system and bottom part of the plants stem. The scion includes the top parts of the stem, the leaves and flowers.
All commercially propagated roses have 1 thing in common: the rootstock and scion will be different cultivars. The processes of rootstock and scion propagation are very different. Therefore, we are going to dedicate a tutorial to each process. In this post, we are going to focus on the rootstock propagation. In part 2, we will discuss scion propagation.
For rootstock propagation, you are going to need:
Rootstocks are most commonly propagated by cuttings. From your mother plant, cut a stem that is about 1cm thick. The length of the cutting can vary from 10cm to 1m, depending on your preferences. If you want more cuttings of shorter length, you must remember it will take longer for them to mature. Longer cuttings will mature faster, but your stock will be less.
Pop your gloves on and strip the stem, leaving the top 2 leaves. You will then need to remove all of the buds along the stem. Using a sharp knife, carefully remove all of the buds. Any buds that remain intact can regrow and lead to bushy growth.
After you have removed all the buds, soak the cuts in fungicide, dip the cut end into some rooting hormone and place in some soil so that roots can start to grow.
After about 6 weeks in a warm, humid environment expect your rootstocks would have rooted. Once sufficient root development has occurred, you can move on with the budding of the scionwood.
