How to Propagate the Hemp Stalk Flower? A Detailed Guide to Common Propagation Methods
You may not be very familiar with the hemp stalk flower variety; many friends have never even heard of it. Today, the editor will introduce the propagation methods of the hemp stalk flower. Let's take a look together!
1. Propagation methods of the hemp stalk flower
The hemp stalk flower is mainly propagated by seeds or by division. For seed propagation, sowing in summer and autumn each year is preferable; the seeds mature from June to July and are sown immediately after being collected; they sprout after about 1 week, and when there are 2-3 true leaves, they are transplanted once, and they can bloom the following year. Division propagation is carried out from after flowering to before new shoots emerge in spring, and it is often grown as a biennial; liquid fertilizer can be applied during the growing period.
2. Introduction to hemp stalk flower planting techniques
1. In the south, sowing is mostly done in early spring in plastic sheds for insulation, and after the seedlings emerge they are moved into containers for cultivation for about 2 months, then potted or transplanted out for field planting.
2. The main asexual propagation method is, after flowering in autumn, to cut off the aboveground plants, keep the perennial roots to overwinter, and in early spring of the following year after the new seedlings sprout, carry out division, or before the new seedlings sprout, dig up the old root clumps, cut the roots as propagation material, with each root segment bearing 2-3 buds, and plant them into a sand bed or nursery field.
3. Keep it often moist; after the weather warms in spring, the seedlings emerge and grow into new plants. For cuttings, mostly when the seedlings are about 10 cm tall, remove them from the base and insert them into a sand bed or vermiculite bed, and transplant them separately after they have rooted.
4. Potted plants need dwarfing treatment. The main approach is to water less and apply less nitrogen fertilizer to control plant growth. You can also use the method of mechanically injuring the roots: when the plant is growing vigorously and has not yet entered the flowering stage, use a shovel in stages to cut off the surrounding fibrous roots in place, so that after the main roots are injured their growth is checked. Repeating this several times can achieve the goal of early flowering and dwarfing.
