A balanced, slow-release fertilizer should be used. It is advisable to fertilize this plant once every two months, starting from the beginning of the growing season and stopping in late summer.
It is important to avoid over-fertilization to prevent the plant from producing a lot of foliage and not enough flowers.
Pruning of Thesium junodii A.W.Hill
Thesium junodii A.W.Hill does not require much cutting or pruning. Only cut back the plant in spring, shortly after new growth emerges. You can trim to remove any dead or diseased foliage. It is essential to maintain the desired shape of the plant.
During the growing season, it is advisable to pinch back any terminal buds that have wilted or faded, to encourage bushier growth. Pruning, in general, should be minimal.
Propagation of Thesium junodii A.W.Hill
Thesium junodii A.W.Hill can be propagated through seeds and cuttings.
Propagation through Seeds
The first step in seed propagation is to collect the seeds from a healthy Thesium junodii A.W.Hill plant. The seeds can be sown directly into the soil or in pots filled with a well-draining potting mix. The seeds should be covered with a thin layer of soil and watered regularly to maintain moisture. The seedlings should emerge within a few weeks and can be transplanted once they are strong enough to survive in the new location.
Propagation through Cuttings
Thesium junodii A.W.Hill can also be propagated through stem cuttings. The best time to take cuttings is during the growing season, when the plant is actively growing. To take cuttings, choose a healthy stem and cut a 4-6 inch piece of stem that has several nodes. Remove the leaves from the lower half of the stem and dip the cut end into rooting hormone powder. Plant the cutting in a well-draining potting mix and water regularly. The cutting should root within a few weeks and can be transplanted once it is strong enough to survive in the new location.
