Before proceeding directly to the issues of cuttings, I would like to briefly define 'precious orchids'. This is a group of orchids, decorative with their leaves, usually with a variety of patterns with shiny veins, shimmering gold, silver or copper, on a solid or multi-colored background of a velvet leaf. Although some genera do not have any patterns on the leaves, the velvety leaves are present.
Macodes aff. sanderiana
Ludisia discolor sp.
Most precious orchids are moisture and heat-loving plants, the optimum temperature for them is 22-29C. When dry, they throw off the leaves and lose their decorative effect.
Examples of precious orchids
As a rule, the most common jewel in our flower shops is Ludisia discolor.
Using her example, I want to show how I multiply jewels. This is necessary if your bush is lush enough and you want to swap plants with someone or give someone the same plant as yours.
It should be noted that, unlike other orchids, precious orchids have a creeping branchy stem (pseudobulbs), so this method is only suitable for precious orchids.
On the stem of ludisia, you can clearly see internodes, with large pimples, these are the places from which roots will appear later during grafting.
Not to be confused with budding buds.
For successful grafting, it is necessary that the grafting has at least 2 nodes.
In the photo, I highlighted with brilliant green, the options in which places you can cut off the stalk. Either below or above.
After that, the cut site is allowed to dry. And either they immediately put it on wet sphagnum and in the greenhouse, or, as I do, I put the stalk in a glass of water.
After 10-14 days, roots appear. All jewels are fluffy.
After the appearance of roots, an already independent plant should be transplanted for permanent residence in the simplest substrate - sphagnum moss, preferably green.
Now you can feel free to give or change.
Precious orchids are recommended to be grown at high humidity in terrariums or greenhouses, as well as in hanging baskets, in sphagnum moss.
I feed Ludisia with mineral fertilizers for orchids. Any company except Pokon will do. Kemiru luxury is also praised.
To water, as such, I do not water it, I soak it. Together with all the other orchids. I take a basin, pour the settled water, add half a bottle of fertilizer and "throw" the pots there for half an hour.
To prevent the earth from floating up, you need to pour water along the side of the pot.
In mid-late October, I cut back the feeding for Ludisia, start feeding every 2 waterings, and in winter after 3.
The problem is that in September the weather is good and the plant is still vigorous, so feeding is needed. Another thing is when it is damp, gray and rain is dripping. Then from a lack of light and a drop in temperature, the plant "falls asleep", and in such a coma it absorbs the least of everything, including fertilizers.
