7 things to know before growing Moon Orchid

1. 1Bright, filtered light

   Avoid direct sun and place it where light is soft and diffused, such as behind a sheer curtain. Strong direct light can scorch the leaves, so it helps to adjust its position with the seasons.

2. 2Water sparingly

   As an epiphytic-type orchid, it dislikes constantly wet roots. Water only once the surface of the growing medium has dried, and make sure water doesn't pool inside the pot.

3. 3Choose a well-aerated medium

   Use sphagnum moss or bark chips that let air reach the roots easily. Avoid dense, soil-like media, which can lead to root rot from excess moisture.

4. 4Repot every few years

   As the growing medium breaks down, drainage worsens, so repot roughly every few years depending on root condition. Doing this during a period of stable temperatures reduces stress on the plant.

5. 5Keep it warm in winter

   Being native to the tropics, it is sensitive to cold, so keep it in a warm spot indoors during winter. Because some plants grow flower spikes as long as 30-75cm, a stake can help support the plant's form.

6. 6Caring for the spike after flowering

   Once flowering ends, you can either cut back the spike or let it continue growing for a possible second flush of blooms. Since the spike arches gracefully as it lengthens, training it along a stake keeps the plant looking tidy.

7. 7What to look for in a plant

   Choose a plant with thick, glossy leaves and well-developed roots. Since this is considered suited to growers with some experience, first-time orchid keepers may want to build up basic care skills before taking one on.
