Propagation methods
The plant Galeopsis ladanum L. var. ladanum can be propagated through both seeds and cuttings. The methods are discussed below:
Propagation from seeds
The seeds of the Galeopsis ladanum L. var. ladanum can be sowed in seed trays in the spring season. The seeds should be sowed in well-draining soil with good organic content. The seed trays should be kept in a warm and bright place and watered regularly. The seedlings will usually emerge within 7-14 days of sowing. Once the seedlings have grown to a height of 5-6 cm, they can be transplanted into larger pots or directly in the ground.
Propagation from cuttings
The stem tip cuttings of the Galeopsis ladanum L. var. ladanum can also be used for propagation. The cuttings should be taken during the summer season from the mature stems of the plant. The cuttings should be around 8-10 cm in length and should include at least two nodes. The lower leaves of the cutting should be removed, and the cutting should be dipped in rooting hormone powder. The cuttings should be planted in well-draining soil, kept in a warm and bright place, and watered regularly. In about 4-6 weeks, the cuttings will develop roots and can be transplanted into larger pots or directly in the ground.
Both propagation methods are effective, and the plants developed from these methods will grow well in the right growing conditions.
