How you propagate an orchid depends on how it grows. A Phalaenopsis sometimes produces a small plantlet, called a keiki, on its flower spike. You can separate it once it has leaves and well-developed roots of its own. An established Cattleya with several growing points can be divided along its rhizome when both divisions will remain viable. That division method does not apply to an ordinary Phalaenopsis with one crown. Before making a cut, identify the orchid and inspect it from the base to the shoot tips. ## What are you looking at? - **A keiki on a flower spike.** A small cluster with its own leaves that may eventually grow roots. - **A new spike or a flower branch.** A shoot without its own leaves and roots is not a young plant ready to move. - **Several growths along a rhizome.** Check whether the plant is a sympodial orchid such as Cattleya, and whether it is large enough to divide. - **One struggling crown.** Focus on caring for the mother plant and postpone propagation. ## How to tell if a Phalaenopsis keiki is ready A Phalaenopsis usually has one main growing point from which its leaves develop. A plantlet sometimes forms at a node on a flower spike. Early on it can be easy to confuse it with a flower branch. Wait until you can identify leaves and see roots emerging from the keiki itself. An aerial root from the mother orchid that happens to pass nearby does not make a keiki independent. Do not rush to separate a plantlet that has only leaves or barely visible root tips. It will have to take up water through its own roots after you detach it. Look for several healthy roots that have developed enough to sit in a small pot without having to bend them sharply. Consider the state of the spike and the mother plant. If the spike is drying while the plantlet still has no roots, examine that situation on its own. Taking the keiki off early does not guarantee that it will survive. ### A plantlet on a spike and growth at the base are different cases You can look at a keiki on a flower spike from several angles and see where its roots start. Growth close to the base of the mother Phalaenopsis may have no obvious boundary. Do not cut through the base as if it were a keiki on a spike. If the point of attachment or the presence of independent roots is unclear, leave it in place. A cut in the wrong spot could damage the mother plant. ## Get a small pot ready before making the cut - **Fit the pot to the roots.** Use a small container that drains freely. Check that the roots will fit without forcing them sharply around one another. - **Prepare a sterile tool.** Use a sharp, sterile blade and sterilize it again before moving on to another orchid. - **Support the keiki.** Cut the section of flower spike holding it without injuring the base or roots. Do not wrench the keiki off. - **Arrange the roots in the medium.** Fill around them with an airy Phalaenopsis medium. Keep the center of the leaves above it and let excess water drain after moistening. Choose the particle size and moisture behavior of the mix for the roots, pot and growing spot. The guide to [orchid growing media](https://dunger.ua/en/blog/orchid-growing-media) explains how to compare those features. A very small plant in a large pot may sit in material that stays damp longer than expected. If roots are fragile or close to the old spike, avoid pressing down on the keiki to force them into the container. See the guide to [repotting orchids](https://dunger.ua/en/blog/repotting-orchids) for a separate look at root inspection and getting the pot ready. ## When an established Cattleya can be divided A Cattleya grows along a rhizome. Its successive growths often have swollen storage structures called pseudobulbs. Choose a healthy, well-developed plant to divide. First trace where the active growths emerge. Plan the cut so each section keeps live roots, several mature growths and a viable growing point. Taking apart individual pseudobulbs merely to fill more pots risks leaving weak pieces. Division can fit into a planned repotting when the orchid is in an appropriate growth phase and condition. If active growth is clearly present on only one side, postpone division rather than taking a second section that may not be viable. Do not assume that all orchids with several stems can be handled like a Cattleya. The genus and any cultivar information on the label help you understand the growth pattern before choosing a method and timing. ## The first weeks in a home growing space Choose a spot with diffuse light and stable conditions. During the heating season in a Ukrainian apartment, the air close to a radiator can be dry, while the area against a window can get colder at night. Find a position out of drafts and away from hot direct sun. Let the state of the medium guide your watering, and let excess water run out of the pot. If a decorative outer container collects water, empty it rather than leaving the inner pot standing in it. The mother orchid and the new pot may dry at different rates. Check them separately rather than relying on the look of bark at the surface. Once the new plant is growing independently, work through the broader routine for [orchid care at home](https://dunger.ua/en/blog/orchid-care-at-home). Record the separation date and take a photo of the roots at the start. Compare subsequent observations without lifting the orchid out of its pot each time. Make the first few checks under similar light so you can tell whether a root changed or only looks different from another angle. If a pot keeps staying wet after the rest of the collection has dried, look at the container, its drainage and the particle size of the medium. There is no need to put it on the same watering calendar as the mother. A written note about the location or pot size is more useful than assuming every member of the collection needs the same care. ### Seed propagation is a separate project Orchid seeds are tiny. In nature, germination often depends on suitable fungi. Controlled propagation uses specialized nutrient media and sterile technique. Scattering seed over the bark in an adult Phalaenopsis pot is not a substitute. If your aim is to keep a copy of a particular plant and a mature keiki is already on its spike, that is a separate and more direct project. If your plant has no keiki, keep caring for it as usual. ### When to postpone the work If the only pot available is too large and the roots are still small, leave the keiki on the spike and gather what you need. Postpone dividing a Cattleya if each piece would have very little healthy growth or you cannot trace the rhizome. If the orchid is declining, check its roots, leaves and growing conditions first. A healthy established parent is a better starting point than trying to save every part of a struggling plant with a single cut. ## Separate feeding for other houseplants  ### [Complex fertilizer for house plants](https://dunger.ua/en/mineral-fertilizers/small-packaging/for-landscape-design/16-complex-fertilizer-for-house-plants) If you keep a ficus and a dracaena beside your orchids, give those plants their own watering and feeding round. This concentrate is an option for those healthy houseplants if they need feeding during active growth. Find your plant in the directions and dilute the concentrate as instructed. For an orchid, check that the product you choose for it suits its type and growing medium. The product page shows the 0.5 L bottle, composition and full directions. Leave it out of keiki separation or rhizome division. Plan groups of houseplants separately rather than carrying care over from one kind to another.

If the spike is damaged or drying, assess its condition first. Leaves without independent roots do not show that a keiki is ready for a separate pot. ### ### ### Share this article ## Related Posts  [Indoor plants](https://dunger.ua/en/blog/categories/indoor-plants) ### Automatic watering for houseplants: choosing and testing a system Choose and test a wick, reservoir or drip setup for your pots before an absence, including excess water and leak checks. 2026-11-06 • 7  [Indoor plants](https://dunger.ua/en/blog/categories/indoor-plants) ### Indoor hibiscus care: light, watering and flower buds Indoor tropical hibiscus care: light, watering, winter conditions, bud drop, repotting and feeding a healthy growing plant. 2026-11-06 • 7  [Indoor plants](https://dunger.ua/en/blog/categories/indoor-plants) ### Soil for peace lilies: choosing a mix and checking the root zone Choose peace lily potting mix, check drainage and wetting, and decide when repotting and feeding are actually needed. 2026-11-06 • 7 Order & Inquiry ## Get in touch  Order mineral and organo-mineral fertilizers directly from the manufacturer.
