Dendrobium loddigesii

Also known as: Loddiges' Dendrobium or Dendrobium seidelianum Dendrobium loddigesii var. album in the subfamily: Epidendroideae

Native to: China Hong Kong

General Information

Loddiges' Dendrobium is a miniature to small sized sympodial cool to warm growing epiphytic, lithophytic or terrestrial orchid belonging to the sub family Epidendroideae native to China and Hong Kong. It is named after the English Botanist in the 19th century.

Plant Description

Sympodial. Grows to 10-18cm. Each new growth has numerous thick lance shaped, oblong shaped leaves that grow to 4-6cm long. Pseudobulbs grow to 8-15cm. The plant tends to climb or sprawl with each new growth and forms pendant or arching growths

Flowers

Numerous long lasting, fragrant blossoms appear

Fragrance

The orchid is fragrant.

Substrate(s)

• Coarse

Care Notes

This orchid goes into a dormancy phase during winter, during this phase it is best not to provide water unless the plant is starting to look thirsty. The lack of water increases the chance of flowering in spring, and also reduces the likelihood of any rot forming. Do not resume watering until new growth has appeared and is growing strongly.

Often a period of intense growth occurs after dormancy. During this time the amount of light, water and fertiliser the plant receives will directly impact the amount of growth that occurs during this time, and in the case of seedlings, will reduce the time required to reach maturity.

It's recommended to heavily reduce the water amount at the middle to end of autumn to trigger dormancy. Leaves on older bulbs will begin to drop during this time while the newer bulbs continue to mature until terminal leaves appear at the tip of the pseudobulbs.

Repotting can be done any time of the year though it's best to do it in early spring when new growth is appearing as this also means new roots will appear to help the plant anchor into the new media and offset any damage to established roots during the repotting process.

Climate

These orchids grow in cool climates, at low altitudes, in cool plains, forests or coastal scrub.

They are forgiving of humidity variances as long as temperatures are kept on the cool side. They can do well outdoors in the garden in cool and temperate areas, though it is important that they are protected from warm dry winds. They can enjoy morning sun especially in winter but will need protection from the hot sun in the afternoon and during summer. With some acclimatisation they may be able to receive more sun.

 

Grows at low to high elevations. Rainfall ranges from 30mm to 394mm per day, heaviest in June and lightest in December. Humidity ranges from 67% to 83%, highest in May and lowest in November. Temperature ranges from 7C to 24C, highest in July (19C to 24C) and lowest in February (7C to 11C).

Watering

These orchids prefer a constant supply of moisture, with a slight drying out between waterings. Saucers can be placed under pots to retain moisture during hot weather, however the saucers should be removed or let to dry every 1-2 weeks to prevent rot. Keep an eye on the plant especially in hot weather and look for cues of under/overwatering and adjust accordingly.

Fertiliser

dormant-medium-demand-orchid Apply fertiliser regularly at half strength year round. Use a high Nitrogen fertiliser during Spring and Summer. Use a high Phosphorous fertiliser during Summer.

Potting

These plants can be sensitive to repotting though should not require repotting regularly. Repotting should be done when the mix has broken down to the point that it doesn't absorb water or holds onto water for far too long, usually the plant shows a decline in growth as well. Repotting is best done after the growing season when the plant has died back.

The mix should be free draining, with a blend of 30% inorganic ingredients such as coarse sand, gravel or perlite, mixed in with about 70% organic ingredients such as peat, leaf litter or decomposed bark. Avoid commercial potting mixes as they can vary wildly and may contain "wetting agents" that can hold onto water for loo long, causing rotting and stunted growth.

 

This plant does well mounted to Stone slabs.
