How Do You Care For Dendrobium Aggregatum?

Dendrobium aggregatum is an epiphyte native to North-East India, Indochina, and Thailand. Plants have been discovered at elevations higher than 500 meters, however they can also be grown in warmer to intermediate environments.

The plant is adaptable to a range of environments as long as it receives adequate light, water, and a winter rest.

Lighting: The Den. aggregatum requires a lot of diffused sunshine (about 35-50 percent shade). Most will thrive in the same light circumstances as most cattleyas.

When the pseudobulbs acquire a reddish color, the plant has received all of the light it can stand and should be left alone unless it begins to sunburn. The amount of sunshine should be kept constant during the plant’s winter slumber (do not give it less light).

Temperature: In their natural habitat, these orchids receive mild to warm daytime temperatures in the spring and summer, and generally lower temperatures in the winter. This plant can thrive in a wide range of climates, with daily temperatures reaching the 70s and 80s.

However, it is not uncommon for this variety of dendrobium to withstand temperatures in the upper 90’s during the summer months if the weather is humid). Winter night temperatures range from 45°F to 60°F.

Watering: Watering may be the most important aspect of success with these orchids. During the late spring, summer, and early fall, their native environments are fairly damp.

Rainfall can be rather heavy for a few months, although it gradually diminishes in the late fall, and the winter months are relatively dry. When the plants are actively growing, water them on a regular basis; mounted plants can be watered daily provided the air circulation is good.

Reduce watering gradually after the new pseudobulbs have formed in the fall, and allow the plant to dry between waterings.

Fertilizer: These dendrobiums thrive from regular feeding when they are actively growing. Any balanced, water-soluble fertilizer can be used, diluted according to package guidelines.

During the active growing season, we feed once each week. Reduce feeding in the fall and fully stop when the plants are dormant in the winter. Feeding should be resumed when the plant begins to develop again or when flower spikes appear.

Winter rest: Den. aggregatum requires a winter rest period. For a few months (November-January), the plant should be exposed to 50–60-degree temperatures at night, with somewhat warmer days.

Watering: Should be gradually reduced, and fertilizing should be discontinued entirely. If the pseudobulbs display considerable shriveling, the plants should be watered sparingly throughout the rest time. Some shrinkage is normal, and the plants may be partially deciduous.

Sun exposure should be consistent from the growth period to the rest period to ensure spring flowers and growth.

pH Range: 5.5 to 6.5

Soil Range: Bark to Bark

How do you grow dendrobium aggregatum?

This plant requires basic care, including: Inspect pseudobulbs regularly to check for any damage or signs of rot. Remove the damaged or dead parts before new growth develops.

Repot each year into a slightly larger container, using fresh soil, which should be worked into the base of the plant with one hand during repotting. Dendrobiums can reach 20″ in height indoors and also require a similar amount of space outdoors in part shade.

Pests/diseases: Diseases such as powdery mildew and spider mites can affect this plant easily. It is generally recommended that hobbyists quarantine their plants for several weeks to ensure that they are not bringing in any pests or diseases.

How do you look after Dendrobium aggregatum?

Dendrobium aggregatum is an epiphyte native to North-East India, Indochina, and Thailand. Plants have been discovered at elevations higher than 500 meters, however they can also be grown in warmer to intermediate environments.

The plant is adaptable to a range of environments as long as it receives adequate light, water, and a winter rest.

Because of its epiphytic nature, this plant thrives best when mounted. A media such as cork, fern bark, or teak is typically utilized. Mounting plants allows them to dry completely between waterings and allows air to circulate.

Orchids, like humans, dislike having ‘wet feet.’ If you are mounting your orchid yourself, make sure to wrap it in a layer of sphagnum moss to keep it from drying out too quickly.

The majority of people use fishing line to secure the plant, however quilting thread and wire are also useful. Once the plant has established itself by embracing the mount with its roots, the ligatures can be removed.

If potted, use a medium that drains fast and thoroughly. Dendrobium’s dislike having their roots disturbed, so it is better to anchor the plant in a substrate like lava rock.

How do you propagate Dendrobium aggregatum?

Propagation of dendrobiums can be done by several methods. Some hobbyists start their propagation with leaf cuttings or pseudobulbs.

Leaf cuttings are generally taken from mature leaves that have not yet begun to grow, and the cutting should be about 3″ long and 1/2″ wide.

When the leaves have been taken from the plant, they should be allowed to dry for several days before planting. The cuttings can be placed in a small container filled with sphagnum moss and misted frequently.

Those who wish to try the leaf method can take just a few leaves from the plant, which should be about 4″ long. After cutting, the leaf is allowed to dry for several days before planting.

A more effective way of propagating dendrobiums is by taking pseudobulbs. The pseudobulbs of the dendrobium can be cut from the parent plant, and these should have a growth bud near the top. The cutting should be no more than 2″ long.

When taking the cutting, tie a piece of fishing line to it, which will allow you to hang it over a small container filled with water until roots begin to grow. Once this happens, you can plant the cutting in a small container filled with cactus/orchid soil and mist regularly.

Where can I find Dendrobium aggregatum?

Actual flowers are rare in the cultivated hybrids. Most of the blooming plants that we see today were raised in tissue-culture labs and look nothing like their natural cousins.

The leaves may be green or variegated. Many clone plants also persist with a single pseudobulb (instead of two, as they do in nature).

The best way to find this plant is by visiting botanic gardens and plant shows, where specimens will be growing outdoors. You can also purchase them online.

How do I identify my dendrobium aggregatum?

Dendrobium aggregatum is an epiphyte native to North-East India, Indochina, and Thailand. Plants have been discovered at elevations higher than 500 meters, however they can also be grown in warmer to intermediate environments.

This plant can be identified by its characteristics. It is an epiphytic, evergreen orchid with a single leaf growing from a miniature pseudobulb. In the spring, racemes of 4-to-12-inch length produce the flowers.

They grow on a bark slab or in slatted baskets with epiphytic orchid potting mix. It is a temperate-growing orchid that requires humidity and some shade from late spring to summer, as well as full light the rest of the year.

It should be Kept dry during the winter. Flowers look their finest in compact containers.

How do you make a dendrobium aggregatum corsage?

Dendrobium aggregatum can be made into a corsage by taking a leaf from the plant and a small sheet of plywood.

Using floral tape, make a tapered loop at the top of the plywood sheet, then roll it down the length of the leaf.

Using screws attach both ends to the plywood sheet. Make another corsage by using a leaf from the plant and another plywood sheet. Attach the leaf to the plywood sheet in exactly the same way as above.

When you want to wear your corsage, attach thumbtacks to each end of the corsage, then use tape to secure them in place.

How do you make a dendrobium aggregatum lei?

Dendrobium aggregatum can be made into a lei by tying it together with cut-flowers or ribbon. For the interior tie, assemble your stems and leaves. For the exterior tied, string cut-flowers or ribbon together.

Hold both ends of the lei by folding them in half and inserting a pencil between both ends. Knot and tie securely with floral tape. When you want to wear your lei, use thumbtacks to secure it onto a collar, shirt or wrap.

How do you prune a dendrobium aggregatum?

In regards to pruning, dendrobium aggregatum plants should be done so in the fall season. You should remove any dead or damaged leaves, pseudobulbs that are withered or brown, and cut the stems with several inches of growth into a woody leaf node.

Pruning helps promote new growth, and can help keep plants from looking overgrown. It is also beneficial if you plan to take leaf cuttings from it. Make sure the leaf is dry before taking it.

Through regular pruning, plants can be kept in a small size and also kept healthy and growing well. If you do not prune them, they will generally look overgrown as they grow and develop a tangled appearance.

How do you repot dendrobium aggregatum?

Terrestrial Orchids in Pots: A good drainage system is essential.

• Combine three parts fibrous peat, three parts coarse grit, one part perlite, and one part charcoal.
• Choose a pot that will hold roots and around 2 years of growth, but no more.
• Check to see whether it has a drainage hole.
• Place the orchid in the container so that the crown is slightly below the rim.
• Fill the pot with wet soil mix, tamping it down to harden it. There is no need to add crockery to the bottom of the pot, but you may choose to cover the hole in the bottom with a small piece of wire mesh or other permeable fabric.
• Epiphytic Orchids in Pots Because epiphytes prefer conditions in which their roots can be exposed, tight pots and close-contact soil mixes do not perform well and will cause rot.
• You can also use a commercial orchid mix and combine 3 parts dust-free, medium-grade bark, 1-part coarse grit or perlite, 1 part charcoal, and 1 part peat moss.
• As with the terrestrial orchid, choose a pot large enough to accommodate roots and roughly two years of growth, but no more.
• Check to see whether it has a drainage hole. Even better, use an orchid planter with vertical vents down the sides.
• Hold the orchid over the container so that the crown is slightly below the rim. Fill pot with moistened bark mix, tamping to firm with the other hand.
• Some epiphytes prefer to grow on a mound or slab of bark rather than in a pot.
• Tie the orchid in place with fishing line until the roots have attached.

Constant humidity is required. Support Staking is required for orchids with long bloom stalks. Staking is most effective when done while the stem grows and before the buds emerge. When potting orchids, many growers prefer to put a stake, although this is entirely up to you.

How do you revive a dendrobium aggregatum?

Dendrobium aggregatum plants can become overgrown, or sickly looking in appearance. If this occurs, the plant can be brought back to life by removing all of the dead or damaged leaves and stems, then allowing plenty of room for new growth.

You should also remove any brown and withered pseudobulbs from your plant as well.

These problems can occur if your dendrobium was overwatered when being watered regularly. If you water the plant too frequently, it can wash out the nutrients in its leaves, which will then result in their browning and wilting.

If this happens, you will need to repot your plant with fresh soil and make sure that you do not overwater again.

How do you water a dendrobium aggregatum?

A lot of water is required for mounted plants. This, of course, is affected by air humidity and temperature. The plant should not be allowed to dry out.

After watering, potted plants should be allowed to completely dry out. This should take no more than a day or two in a well-drained medium.

Orchids are extremely sensitive to excessive salinity; therefore, distilled rainwater (also dependent on region conditions) or reverse osmosified (R/O) water should be used if the water has been softened or contains a high concentration of minerals.

How many times does dendrobium aggregatum bloom?

Dendrobium aggregatum is an epiphytic orchid, and thus it is also a monocarpic orchid; which means it blooms only once.

In order to produce the flower, plants need to go through a flowering process that uses all their energy. The bloom time range is mid spring to late spring, and the flowers last approximately 1-2 weeks.

Den. aggregatum bears exquisite orange or yellow flowers that hang from a slender inflorescence. The inflorescence grows from around the base of the pseudobulbs and takes many weeks to develop enough to bloom, which can be excruciating for even the most patient gardeners.

Flowers can live anywhere from a week to a month if properly cared for and kept under high humidity. In average, an inflorescence2 will have ten to twenty blooms, while younger plants may have fewer. This plant’s inflorescences do not rebloom and should be removed once they have dried and become brown.

If your dendrobium continues to bloom after the first time, this indicates you are over-watering it.

Is dendrobium aggregatum a houseplant?

Dendrobium aggregatum is a houseplant; however, it can be performed in a hanging basket if desired. It has distinct foliage besides the blooms, and it can be grown under direct sunlight in a moderately warm window.

As with all plants, when you have an orchid that was not grown indoors, it is best to maintain the same environment as you had when growing it indoors. Keep the air humidity levels at 70-80%, and provide temperatures between 70-80 degrees.

Is dendrobium aggregatum edible?
