How to Propagate Lophocereus marginatus plant?
1
For seed propagation, collect the seeds from the ripe fruits. Clean them carefully and let them dry for a couple of days before planting.
2
For cutting propagation, use a sharp knife to cut healthy and disease-free cuttings from the parent plant. Allow it to callous over for a day or two before planting.
3
Plant the seeds or cuttings in a well-draining medium. Make sure the cutting is positioned upright in the soil. The success of planting is improved if the temperature is maintained around 20 to 25 degrees Celsius.
How to Repot Lophocereus marginatus plant?
1
Lophocereus marginatus, also known as Mexican Fence Post, needs to be repotted when its roots are noticeably coming out of the bottom of the pot or when the plant is noticeably too large for its current pot. Also, if the plant seems to struggle with growth, it might be time for a larger home.
2
Mexican Fence Post prefers a pot which provides ample room for root growth but is not so large that it will slow the plant’s growth. Moreover, the pot should have good drainage to prevent waterlogging. Terra-cotta pots, which naturally wick away excess moisture, are a good choice.
3
A loose, well-draining cactus mix is optimal. It will provide ample room for root growth and prevent waterlogging. Regular potting soil is too dense for this plant, which needs excellent drainage to stay healthy.
