When a moth orchid has not flowered, first check whether it is ready to grow a new flower spike. A healthy Phalaenopsis may put out a new leaf or roots after blooming. For a plant in that condition, light and temperature are useful things to check. Soft roots, soggy bark or a damaged crown call for recovery first. Two plants can look similar on a windowsill until you check the growing medium and look for new growth. ## What to check before changing the routine - Confirm that the orchid is a Phalaenopsis and note when it last flowered. - Look for firm leaves and new leaves or healthy growing root tips. - Check light and temperature near the leaves at different times of day. - Check how the mix dries between waterings and whether the pot can drain. ## Is the plant ready to flower again? An orchid that has just shed its flowers and begun a new leaf may take a while to form another spike. Reblooming time varies by hybrid. A young plant or one that has lost some roots needs time to grow. Record when it last flowered and photograph the whole plant. Comparing the next photograph with the first helps you see changes in a leaf or root that you may miss when checking every day. Look at several signs together. Firm leaves, solid roots and fresh growth give you reason to check light and temperature. If the leaves go limp while the bark stays wet, look at the roots. Extra watering without an inspection can leave damaged roots sitting in wet medium. If a plant declined soon after purchase, consider whether it was exposed to frost on the way home, kept in a draft or placed beside a radiator. ## Start with light Bright, indirect light is generally suitable for getting a Phalaenopsis to flower again. In Ukraine, short winter days, overcast weather or a neighboring building can leave a windowsill dim. An east window or a place near a sheer curtain is often brighter than the middle of the room. Move the plant gradually to a brighter spot and check whether the leaves heat up. Spring sun through the glass can be intense, even in a spot that was comfortable in winter. Leaf color gives you a clue to investigate. Very dark leaves in a shaded spot suggest checking the light. A pale patch on the window side after a sudden move can indicate scorch. Compare the same leaf under similar light to distinguish a color change from a shadow. If the window gives too little light, use a plant lamp according to its instructions. Maintain a regular dark period at night and check that the lamp does not heat the leaves. Watch a new location for a few days before moving the plant. See whether it receives diffuse light in the morning and afternoon and whether a heavy curtain shades the pot. A glazed balcony can reduce the light reaching a plant inside the room. On the sill, you may be able to move the orchid away from the radiator without taking it away from the window. ## Measure temperature near the leaves Moderately cooler conditions during active growth can help many common hybrids initiate a flower spike. Keep the orchid in a protected place indoors. Long periods of daytime heat matter, too. Record day and night temperatures near the leaves, rather than watching only the difference between the two. If a radiator warms the orchid in the daytime, briefly airing out the room at night does not reproduce a stable, moderate environment. Keep the pot away from the heater and cold glass. When you air a room in autumn, keep the plant out of the stream of cold air. Once buds are present, keep the conditions as stable as possible. Sharp changes in temperature and drying can harm the buds. If you open the balcony door every day, give the orchid a bright spot outside the draft so you can leave the flowering pot in place. ## Look at the roots and bark before feeding Inspect the visible roots through the wall of a clear pot. Healthy roots feel firm. Dry exposed roots can look silvery and turn green when wet. Soft dark patches and bark that breaks down and stays soggy need attention. Aerial roots extending beyond the rim are normal. Leave them intact and avoid forcing them into wet bark. Check whether water collects in the decorative pot after watering. For a plant recovering from poor root health, focus on the roots, drainage and an airy mix. See how to tell when a Phalaenopsis needs water if you need to reassess that part of your routine. The guide to [caring for an orchid at home](https://dunger.ua/en/blog/orchid-care-at-home) covers the basic growing conditions. Give a newly repotted or weakened orchid time to show new growth before you change several other parts of its care. ## What to do with the old flower spike A new root generally has a smooth, tapered tip with a surface behind it that can turn silvery. An emerging flower spike more often grows from a leaf axil and has a flatter tip. If you cannot distinguish the two, let it grow for a while before cutting anything. Remove a dry brown spike carefully with a sharp, sterilized tool. A side bud can grow on a green spike, though not all hybrids do this. If the orchid is weak or has lost roots, give it time to recover. ## Track the change you made - Photograph the leaves, roots and place where you keep the pot. - Note when you watered and how quickly the bark loses excess moisture. - If the roots are sound and the spot is dark, improve the light and let the plant respond. - If the orchid gets enough light, check daytime heat and drafts before looking for other causes. Change one condition at a time unless the plant needs immediate help to recover. If you move the pot, alter watering and fertilize in one day, you will not know which change it responded to. At your next check, compare the new leaf and root tips against the photographs. Avoid working toward a deadline. Active growth tells you how the plant is doing before it produces a flower spike. For example, if the orchid has firm roots and the room looks bright at noon, see how much light actually reaches its leaves earlier and later. Try one brighter position with similar warmth before adjusting watering. If the pot sits by a warm window all day, take a temperature reading there on several afternoons before moving it to a cooler place. ## There is a flower spike, but the buds are drying If buds have appeared but are drying, look for recent changes. Did the pot move rooms, did the heating come on, or did the mix dry faster than usual? Note when the problem began and where the plant was. If it followed airing out the room, protect the orchid from the cold draft. If the bark is wet, inspect the roots first. Avoid making several changes to compensate for lost buds. A thin stake can support a leaning flower spike. Check where the roots are before inserting it. Fasten the spike loosely without pulling it into position, and leave the tip with the buds at its natural angle. ## Feeding other plants on the windowsill  ### [Complex fertilizer for house plants](https://dunger.ua/en/mineral-fertilizers/small-packaging/for-landscape-design/16-complex-fertilizer-for-house-plants) A moth orchid, a ficus and a dracaena can share a windowsill.
