Big, colorful, clustered blooms are what make the florist hydrangea plant so special. These blooms are what people are looking for when buying a hydrangea. They come in a variety of different colors which make them a perfect decor statement in any home.

Care Requirements

LIGHT

Your florist hydrangea requires a lot of light when growing indoors, so make sure to place it in bright indirect light. Please don’t put it in direct sunlight as you could burn the beautiful flowers. 

WATERING

Water your florist hydrangea frequently when the plant is blooming but be careful not to overwater. It’s best to decrease the amount of water after blooming but never allow the potting mix to become bone dry.

TEMPERATURE

Florist hydrangeas like to be placed in an area with cooler temperatures. Cooler temperatures will help extend the life of their beautiful blooms. Keep these plants be kept in temperatures below 80° F. They grow best in temperatures between 50° and 60°­­ F.

FERTILIZER

Feed the hydrangea every week while the plant is blooming, using a water-soluble fertilizer diluted to half strength once the blooms are spent feed monthly. 

HUMIDITY

These plants love higher humidity, so placing your florist hydrangea in a bathroom or kitchen is ideal. 

PET FRIENDLY

Mildly toxic if eaten in large quantities. Keep away from dogs, cats, and children.

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.
