Equal parts peat moss, potting soil and sand

Hyacinths are flowering bulbs that come in a variety of colors such as pink, white, yellow and blue. Typically grown outdoors, they bloom in spring and are a fresh reminder of warmer days to come. However, when planted indoors they can be forced to produce bulbs any time of the year, thus adding color and a mild fragrance even in the winter.  

Follow these steps to grow hyacinth indoors.

Step 1 – Hyacinth Bulbs

When purchasing bulbs from a nursery, keep in mind that a larger bulb will yield a bigger flower, some up to 12 inches tall, so make sure your bulbs are the same size.

Step 2 – Container Selection

Hyacinth bulbs can grow in plastic or clay pots, so select the type that suits you. Make sure the pots have adequate drainage holes and place a few broken pieces of crockery over them to prevent clogging.  

Step 3 – Container Preparation and Bulb Planting

Place a mixture of equal parts moss, potting soil and sand into the container. Moisten the consistency and press it down. Keep adding more until it reaches an inch below the rim of the container.

Plant the same size bulbs in the container with their pointed edge up. Place them as close as possible, but do not let them touch one another or the edges of the container. Press the bulbs gently so their tips are just below the rim.

Fill the container with more mixture until it is ½ inch below the rim. Press down again and water the container well.

Step 4 – Container Location

Place the container in a cool dark place indoors, such as a garage or a cellar, for ten to fourteen weeks to allow the production of a good root system. Make sure you water the container frequently.

After fourteen weeks, acclimatize the container by moving it to a dim corner for a few days and then placing it in full light.  

Step 5 – Bulb Care

Use any household fertilizer at half the recommended strength to feed your bulbs every week. Keep your potting mix moist, allowing the top ½ inch to dry between watering.  

Turning the container every few days will allow each side of the plant to get equal amounts of sunlight and help the stems grow straight. In two weeks, the stems will elongate and flower buds will emerge from the neck of the bulbs. Placing the container on a sunny windowsill or patio will help prolong the bloom.

Keep the room temperature between 65 and 68 degrees F to enjoy your hyacinth's bloom for a good two weeks.  

Step 6 – After the Bloom Period

After flowering, plant the bulbs outdoors for another show of flowers in a few years. Attempts to force the same bulbs indoors will be futile, because they cannot be used as houseplants again.
