Cymbidium Orchids

  • EASY-TO-GROW
  • GORGEOUS COLORS
  • HARDY FLOWERS

Cymbidium flowers last for several months, and they typically bloom early in the year to brighten a winter day. They are hardy enough to withstand a few degrees of frost. Cymbidiums are grown outdoors in many parts of the country. Cymbidium orchids have an oriental look with their grass-like leaves and the flowers high above the foliage. Flowers have excellent, lasting qualities and come in every color but blue.

Care Requirements

LIGHT

This is the single most important factor for good growth. Lack of light is the most common reason for a blooming size plant to fail to produce flowers. These plants like as much light as possible without burning their leaves.

WATERING​

A hot, wet summer is fine as most cymbidiums originate from monsoon areas. A bit dryer during the cool winter season is preferred. The best way to judge water needs is to pick your plant up and water according to weight. A dry plant will feel very light.

HUMIDITY

Adjust humidity by seasons. Higher in the summer growing months, around 50-70%, and lower in the winter, around 40-50%.

FERTILIZER

Feeding is largely dictated by seasons. More fertilizer with higher levels of nitrogen during the summer months and a small amount of balanced fertilizer during cooler months.

TEMPERATURE

Cymbidium orchids will tolerate extremes but remember, a good rule of thumb is if you are comfortable in the growing area, then your plants are going to be comfortable, too. Daytime temperatures should be kept below 86 degrees. Night temps should be between 40 – 65 degrees. Plants prefer the lower end of these temperature ranges during bud formation and flowering. All orchid flowers last longer if kept on the cooler side.

Our Advice

Potting Cymbidiums should be done at least every two years. Cymbidiums prefer a more moist medium than most orchids. A mix used for paphiopedilums or seedlings will usually work just fine. The good culture of all orchids must have good air circulation. Proper ventilation reduces the chance of disease and helps flowers to last longer in good condition.

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.
