How to Grow and Care For Miniature Orchids at Home

If you’re looking for an easy way to bring a pop of color into your home, mini orchids are perfect low-maintenance plants to grow. These flowers are slightly smaller than their full-size counterparts and they have similar care requirements. Because of their size, however, there are some subtle differences we’ll help walk you through. Keep reading to learn more about caring for your flowers, pruning at the end of the season, and repotting your orchids so they continue to thrive.

Things You Should Know

Water your mini orchids once a week when the soil feels completely dry to the touch. Let the excess water drain out from the holes in the pot.
Keep your orchids in an east-facing window so they’re out of direct sunlight. Maintain temperatures around 65–85 °F (18–29 °C) and humidity levels at 50%.
Apply a ¼-strength dilute of 20-20-20 fertilizer each week after you water your orchids to provide nutrients throughout the growing season.

Water your mini orchids once a week when the potting medium dries out. Stick your finger or the point of a sharpened pencil 2 in (5.1 cm) into the potting medium. If the soil still feels wet, then leave your mini orchids alone for now. If the soil is dry, water your plant by pouring about 1.5 fluid ounces (44 ml) directly onto the soil. Let the water move through the potting medium and let the excess drain out from the bottom of your pot.^{[1]

Mini orchids are tropical plants, so they thrive in warmer conditions. For best results, maintain the temperature on the high end of the scale during the day and drop it to the lower end in the evenings. Never allow the temperature to drop below 55 °F (13 °C) since this could stress out your flowers and keep them from blooming.^{[10]

Research source}
4
Keep the mini orchids at around 50% humidity. Mini orchids thrive in humid conditions, so try lightly misting the plant every 1–2 days to help increase the humidity. Alternatively, set a tray of pebbles and water underneath the water to naturally increase the humidity. If you need to raise the humidity even more for your orchids, run a humidifier in the same room during the day.^{[11]

- Keep a humidity meter near your flowers so you can easily track the moisture levels in the air.
- Avoid leaving your flowers near open windows or air vents since it could reduce the humidity around the orchids.
5
Fertilize your mini orchid weekly with a diluted 20-20-20 mix. Use a fertilizer mix that’s urea-free and has a balanced mix of nitrogen, phosphorus, and potassium. Mix 1 part fertilizer with 3 parts water to dilute the mixture to ¼-strength. Each week after you water your mini orchids, follow up with the diluted fertilizer to ensure the flowers grow in strong and healthy.^{[12]

- Avoid giving your orchids fertilizer when the soil is dry since you could burn the roots and prevent them from absorbing water or nutrients.
- Skip fertilizing your orchids during the winter months when they’re not actively growing so you don’t stress out your plant.^{[13]

- Avoid removing any leaves that still look healthy since they may still provide water and nutrients to new growths on your mini orchids.
2
Prune phalaenopsis orchids above the stem’s second node for more blooms. Phalaenopsis, also known as teacup or darling orchids, is the only type of orchid that can bloom twice during the same growing season. Once the flowers dry out and shrivel, gently twist them to remove them from the stem. Then, use a sharp knife or gardening shears to cut just above the second node, which is where leaves or flowers grow from the stem. Within a few weeks, your orchid will have a second round of flowers.^{[16]

Research source}
- If you leave phalaenopsis orchids without cutting them, flowers may grow back in the same spots as the old ones, but they may not get as large as before.
- Mini piccola, cattleya, and cymbidium orchids only bloom once for the season, so they won’t rebloom if you try pruning them.
Once all the flowers have dried out and shriveled on the first or second bloom, your orchid is done flowering until the next season. Use a sharp pair of pruning shears to cut the stems back down to the soil. During the next season, your orchids will grow back in and have new blooms.^{[17]

Repotting

1
Move your mini orchids to a larger pot every year. Mini orchids have fast-growing roots, so a yearly repotting helps ensure your plant stays happy and healthy. If you notice that leaves are dying out more quickly or that “air roots” are growing out from the pot’s drainage holes or above the soil, then it’s time to repot your plant.^{[18]

- Leaving your orchids in the same pot could stress the roots and make them brown or soggy.
2
Get a well-draining pot that’s 1–2 in (2.5–5.1 cm) wider than the old one. Mini orchids have fast-growing roots, but they don’t like to be compact inside of the pot. Measure the pot that your orchid is currently planted in, and choose a slightly larger one for repotting. Make sure the pot has drainage holes at the bottom so water can drip out and prevent the roots from becoming soggy.^{[19]

The spikes are the tall solid stems where the flowers grow and bloom. If the spikes still look green and healthy, snip 1 inch (2.5 cm) above the top-most node on the stem. When the spikes look yellow or brown spikes, then cut them 1 inch (2.5 cm) above the bottom node instead.^{[22]

Remove the mini orchid carefully from its current container. Gently squeeze the sides of the orchid’s current pot to help loosen up the roots and potting mix. Then, gently grab the base of the orchid with one hand and the pot with your other. Tip the mini orchid to its side or upside-down, and slowly squeeze or rotate the sides of the pot until the clump of roots comes free.^{[23]

- Try not to pull the orchid straight up and out of the pot since you’re more likely to damage the roots or leaves.

- Leave healthy roots that are white or green and feel firm so your orchids can grow in strong in the new pot.
- Keeping old potting mix between the orchid’s roots can increase the chances of rot forming.
7
Move your orchids into the new container with the potting mix. Scoop some of the potting mix you soaked into the bottom of the pot as the base layer. Then, set your orchid in the middle of the pot so that the base of the lowest leaf dips below the pot’s rim by ¹⁄₂ inch (1.3 cm). Slowly add the remaining potting mix around the orchids to fill in the container until the entire root system is covered.^{[26]

- Periodically tap the side of the container with your hand to help the potting mix settle it.
- Try gently lifting the orchids up by the stem after filling in the potting mix. If the pot starts to slip, add more mix and gently pat it down to make the orchid fit more securely.
8
Water your orchids lightly. Set your orchid inside of another pot or on a saucer and pour water onto the potting mix until it’s full. Let the orchids sit in the water for about 10 minutes before removing the container and letting the excess water drip out from the drainage holes.^{[27]

- Avoid letting the orchids sit in the water for any longer since they may become waterlogged and root rot may form.

My recommendation for orchids (and all epiphytes,) is to use rainwater if you can. There's something really magical about all of the microbes and good stuff in rainwater that really helps orchids get satiated and well-nourished.

The good thing about outdoor orchids is that you hopefully shouldn't need to do very much as long as they're in the right environment outside. Orchids like dappled sunlight. They naturally grow on rocks and tree trunks. So putting your orchid in a nice hanging basket or wiring it to a tree should work great. Of course, if you don't get a lot of rain or humidity, you'll need to water the orchid yourself.
