Nobile Dendrobium Orchids

  • COLD HARDY
  • EASY-TO-GROW
  • WINTER BLOOMING

The Nobile Dendrobium orchid is a genus of the Dendrobium orchids. Dendrobiums are native to the far east and grow epiphytically on tree branches from the warm lowlands to the cool highlands up to 4000 feet. Kept dry, they can survive in winter down to 35 degrees. Most blooming occurs from February to April.

Care Requirements

LIGHT

Nobile Dendrobium orchids require lots of light. No shade is required during the winter months, and only about 30% shading is suggested during the summer months. With this amount of light, good air circulation is a must to keep leaves from burning.

WATERING​

A direct relationship exists between temperature, light, and watering. As temps begin to rise in the spring, watering should be gradually increased. In the warm summer months, water frequently to keep plants from drying. As temps decline during the fall, reduce watering. During the cold winter months, water only enough to keep the canes from shriveling – about 2 or 3 times a month. Water temps should feel tepid to the touch.

TEMPERATURE

Nobile Dendrobiums orchids prefer temperatures ranging from 55 – 85 degrees. Lower temps around 50 degrees for about a month are needed to initiate flowering. Try placing the plants in a cool window or outside to initiate flowering. Stagnant air should be avoided with all orchids.

FERTILIZER

Use fertilizer sparingly with all orchids. Nobile Dendrobium orchids like to have a high nitrogen mix to initiate plant growth. If potted in a bark mix, use 30-10-10. Withhold all fertilizer in winter.

Our Advice

 Do not overpot Nobile Dendrobium orchids. The plants usually appear to be too small a pot—bark mixed with charcoal, sphagnum moss to maintain healthy roots. Osmunda and tree fern can all be used as potting media.

Care Requirements

LIGHT

Hydrangeas do well in partially shaded areas like under a large tree or on the side of a house. They like to receive sun in the morning, and the partial shade is in the heat of the afternoon. In Colorado, too much full sun will cause them to get sunburned.

SOIL

Hydrangea shrubs need to have well-draining soils that is rich in organic matter. Most Colorado soils will benefit from the addition of peat moss and compost that helps retain moisture. The pH determines the colors of the blooms. Acidic soil will give you blue flowers, and alkaline soil gives you pink flowers.  

FERTILIZER

If hydrangea shrubs are given too much high-nitrogen fertilizer, they may grow full and lush, but there will be fewer flowers. If the soil is rich, fertilizer is not needed. Otherwise, a light application in March or April may be warranted.

WATERING

Make sure to water your hydrangea shrubs regularly. Those big blooms require a lot of water to stay lush and full. About one inch of water throughout the week is ideal. If they receive more sun give them at least two inches during the hotter summer days.

Our Advice

  • Allium flowers need full sun for the best blooms. 
  • Plant allium bulbs when temperature is consistently in the low 60’s or lower. 
  • Allium bulbs and flowers enjoy having soil that is well-draining and has organic matter. Amend the soil with top soil, compost and organic material. 
  • Fertilize when planting the allium bulbs with either Espoma Organic Bulb-tone or Hi Yield Dutch Bulb Food. Applying fertilizer at least 3″ below bulb will make sure the roots get the most from the fertilizer. 
  • Plant allium bulbs 4 – 6 inches deep with the old roots facing the ground and the pointed end facing up. 
  • Water the planted area immediately after planting but no additional watering in fall or spring is necessary. 
  • Apply a 2 – 3 inch layer of  mulch to the planing area in mid to late fall.
