Repotting dendrobium orchid

Dendrobiums are best repotted after they have flowered, just as their new growths are appearing between October and early December. If their roots are in good condition, simply transfer the plant to a larger pot and fill in with new mix.

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.

Where is the best place to put a Dendrobium orchid?

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.

Should I mist my Dendrobium orchid?

Yes! Orchids generally love humid conditions because they're a tropical plant. The easiest way to recreate their humid home is by misting them with a spray bottle.

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.

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 Dendrobiums be watered?

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 do Dendrobium leaves fall 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.

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.

When should you not repot an orchid?

Most orchids need to be repotted every one to two years, but you should wait until the blooming cycle is complete to take this step. Once your orchid enters the resting period, watch for the signs that it has outgrown the current pot.

How long do Dendrobium orchids live?

Like other orchids, Dendrobium orchids can survive indoors for between 10 to 15 years with good care. To care for this popular group of orchids, keep them in a space with temperatures between 68-85 degrees Fahrenheit during the day and 65 to 75 degrees Fahrenheit during the night.

How do I get my Dendrobium to bloom again?

Temperature and Humidity Nobile Dendrobium need cool night temperatures in the fall and winter months in order to stimulate flower bud development. Maintain day temperatures of 70°F to 75°F (21°C to 24°C), and night temperatures of 50°F to 60°F (10°C to 15°C) until buds appear.

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.

Do Dendrobium orchids Rebloom on the same stem?

Re-blooming the Dendrobium Orchid Dendrobium species can flower again on a new pseudobulb which forms in the spring. When this new pseudobulb has developed, it can produce one or two new branches. The compactum species flower on new pseudobulbs, but also on the same cane.

What to do when Dendrobium finished flowering?

Once blooming has finished, increase watering, begin regular fertilizing, keep it in temperatures of between 65-85 °F (18-30°C) and ensure it gets plenty of bright light to maximize vegetative 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.
