Repotting dendrobium orchids

REPOTTING: Your dendrobium prefers not to be disturbed, so only repot when the plant has filled the pot and then, preferably in the spring.

What kind of soil do Dendrobium orchids need?

Soil Requirements for Dendrobium Orchids They are epiphytic so they don't require potting soil. Use an orchid-suitable medium that is mixed with fir bark or perlite and peat moss. The most essential requirement for the growing medium used is that it must be well-draining and that it holds enough moisture.

Do Dendrobium orchids like to be root bound?

Dens do like to be root bound so do not repot in too large of a pot. Our Dendrobium Mix is made of inorganic material to allow the dens to grow undisturbed for many years. Often, when you purchase a den it looks as though it is potted in a piece of bark or wood.

Do Dendrobium orchids need clear pots?

If you're growing moth orchids (Phalaenopsis) you need to grow them in clear containers to allow their green roots to photosynthesise. Dendrobium and Cymbidium orchids don't have photosynthetic roots, so can be grown in opaque pots.

Should I water orchids before or after repotting?

About an hour before you want to start repotting a plant, water it thoroughly and completely. This will give the roots a chance to soften and become pliable. If they have attached to the pot surface, they can be removed more easily. If they have to be untangled, they are more likely to bend than break.

Should I soak my orchid before repotting?

Prepare some cinnamon (yes, the kind you use to cook with, as in cinnamon buns) or sulfur. You will need them to dust the roots after they are cut to disinfect them. Soak your orchid in a bucket of water for half an hour or so to loosen the potting medium and make the roots more flexible.

Do Dendrobiums like full sun?

Dendrobiums need lots of light, but not direct sun. A lightly shaded south window is best. East or west facing windows are satisfactory if bright (avoid direct sun except at the beginning or end of the day). Dendrobiums can withstand hot weather if adequate ventilation and humidity are provided.

What is the best medium for Dendrobium orchids?

Use a commercial orchid potting medium, which generally contains peat moss, perlite, or fir bark. Or make your own using those ingredients. Make sure the medium has aeration and is well-draining, so the roots aren't left in too much moisture for a lengthy period of time.

How often should I water my Dendrobium orchid?

Since Dendrobiums are often large plants in small pots, they should be watered relatively frequently, sometimes as much as twice a week. Your plant should be almost dry before watering, though. Seasonally, water Dendrobiums less in the fall and winter, and gradually more as temperatures rise in the spring and summer.

Why are my Dendrobium leaves falling off?

Exposure to ethylene during shipping. Orchids naturally produce the hormone ethylene as a byproduct during leaf senescence. The presence of this hormone accelerates the process of leaf drop.

Should I cut Dendrobium stem?

However, Dendrobium orchids don't like their stems to be cut, even after the flowers fall off. Instead, allow the bare stems to produce blooms again next year. That said, dead stems and roots can be removed to promote healthy growth.

Why do Dendrobium leaves turn yellow?

Yellow Leaves as a Natural Occurrence Some types of dendrobium orchids are deciduous. The leaves will yellow as the plant pulls the nutrients out of them and then all the leaves on the cane fall off. While this seems traumatic, it is a natural process for these types of orchids in their cycle to rebloom.

Do orchids like big or small pots?

Most orchids require a 4, 5 or 6 inch pot. There are seedlings and miniatures that require smaller pots, older specimen plants and some genera (Cymbidium, Phaius, large Cattleya) that often require 8 inch pots or bigger but the majority of orchids sold in groceries, box stores, florists and the like are not these.

Do orchids like deep or shallow pots?

Most orchids do prefer shallower squat pots, as their roots don't like all the moisture retained in deep pots and they just don't need the depth anyway as their roots spread out, not down.

How do you care for a potted Dendrobium?

Mist regularly and feed every third watering during the growing season. In winter, move your Dendrobium nobile orchid to a cool, bright position with a temperature between 10-13°C (50-55°F), and water only if the stems start to wither. They need as much direct light as possible in winter, to allow the stems to ripen.

Why is my orchid dying after repotting?

The most common reason for a dying orchid is from root rot, caused by either too much water or the wrong type of potting mixture that doesn't allow for drainage. If your orchid is losing all of its leaves or all the leaves are turning yellow, this is a sign of crown rot or stem rot and it may not be able to survive.

Do orchids go into shock after repotting?

The only time you do not want to repot a Phalaenopsis orchid is when the plant is in bloom. If you do so, all the blooms will drop off due to stress and transplant shock.

What is the best mix for repotting orchids?

Fir and Monterey bark is the most commonly used potting media for orchids. It is long-lasting, porous, and free-draining. Clay pellets are commonly added to mixes to prevent compaction and add drainage.

Do you trim orchid roots when repotting?

When repotting your orchid, usually once every year or two, you may find that some of the roots are not very healthy. You should remove these roots before returning your plant to its pot. With your sanitized shears, trim dead roots about an inch above the point where they have begun to die.

Should soil be wet when repotting?

Question: Do you repot when the soil is dry or damp? Answer: It is best, and easiest, to repot from moist soil into moist (but not soggy) soil. “Moist” meaning the plant hasn't just been watered, nor does it need to be immediately watered–it will need watering in another day or two.
