Amaryllis Bulbs

  • FAST BLOOMING
  • GOOD FOR INDOOR FORCING

Amaryllis bulbs are prized for their exotic trumpet-shaped flowers. They add dramatic color to homes and gardens and make wonderful gifts to gardeners from beginners to experts. Amaryllis bulbs prefer to be kept on the dry side prior to forming a bud. Water only when the soil is dry. When a bud and stem have formed water more frequently, still taking caution to avoid over-watering.

Care Requirements

LIGHT

Amaryllis flowers like to be in full sun to partial shade

SOIL

Amaryllis bulbs do best in well-draining soil. Use a soil that has organic material like peat moss or compost. 

FERTILIZER

Amaryllis bulbs do not need to be fertilized. 

BLOOM TIME

Amaryllis flowers will bloom within 6 – 8 weeks from being planted. 

PLANTING DEPTH

Planting amaryllis bulbs between 1 – 2 inches in depth is perfect for them. 

PLANT SPACING

Amaryllis bulbs grow best in containers. 

Our Advice

  • Amaryllis flowers love a sunny location but can tolerate some partial shade.
  • Amaryllis bulbs and flowers enjoy having soil that is well-draining and has organic matter. Amend the soil you are planting in with organic material such as compost, manure or we suggest peat moss.
  • The diameter of the pot should be about 1 inch wider than the widest part of the bulb and twice as tall as the bulb to allow space for good root development.
  • Set the bulb in the pot so the roots rest on the potting soil. The bulb should sit up above the edge of the container.
  • Water immediately after planting and let the water drain freely until the soil is moist.

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.
