Preparing hyacinth bulbs for indoor planting

When buying flower bulbs always choose large, healthy looking bulbs with no blemishes.

This will ensure that the bulbs have plenty of stored nutrients for long lasting flowers.

You can purchase bulbs that have been pre-chilled for immediate planting or if you buy regular bulbs you’ll need to keep them cold for at least 6 to 10 weeks before you plant them.

You can place the bulbs in a cool basement, garage or refrigerator but keep them away from fruits and vegetables because the ethylene gas that they produce can damage the bulbs.

HOW TO GROW HYACINTHS INDOORS

After the bulbs have been chilled for 6 to 10 weeks it’s time to plant them.

Choose a small container with drainage holes at the bottom.

Hyacinths will grow in shallow pots, even with half the bulb exposed at the top so you don’t need a deep pot.

You can plant one bulb in each pot or plant a clump of bulbs in a larger pot. Just make sure that the bulbs aren’t touching.

Fill the pot with a good quality, well draining potting mix and water well.

Hyacinth bulbs will rot easily if they’re overwatered, so let the soil dry out a bit in between waterings.

Place the pot in a cool spot in the house until the leaves begin to appear.

As leaves emerge, move the pot to a sunny windowsill and give it a feed with a slow-release bulb fertilizer.

It normally takes about 3 weeks for the flowers to open after the first leaves appear.

Hyacinth flowers usually grow 8 to 10 inches (20 to 25 cm) tall and they’re self supporting, so you shouldn’t need to stake them. 

If you notice a flower flopping over you can support it with a small stick.

Occasionally you’ll get two or more flower heads from the one bulb.

Growing hyacinths in water indoors

Hyacinths can even be grown indoors without soil.

The easiest way to grow hyacinths in water is to use a hyacinth vase, which will prevent the bulb from rotting.

They’re specially made so the bulb can sit without touching the water, while the roots dangle below.

To plant a hyacinth bulb in water you’ll need to chill the bulb just as you would if you were planting it in soil.

After chilling, place the bulb in the vase with the water level just below the bulb.

Leave the vase in a cool, dark place until roots and shoots appear.

When the shoots are about 3 to 4 inches (7 to 10 cm) tall, move the vase to a sunny spot.

Replace the water regularly and turn the vase every few days to prevent the flowers leaning over towards the light.

Caring for hyacinth bulbs after flowering

Hyacinths that have been grown in water won’t flower again because they use all of their energy to bloom without soil.

Water grown hyacinths should be composted once they’ve finished flowering.

Hyacinth bulbs grown in containers can be treated as annuals and replaced each year or you can remove the spent flowers and allow the leaves to die back naturally.

The bulb will use photosynthesis to store nutrients for the next season.

After the leaves have died back, the bulbs can be moved to the garden where they may bloom again the next season.

Indoor hyacinth problems

Hyacinths grown indoors can be affected by a number of different insects so it’s a good idea to check the leaves and flowers regularly and if you notice any insects, treat the plant with neem oil.

Yellowing or browning leaves are usually a sign of overwatering and it may indicate that the roots have started to rot. [1]

So there are my tips for growing hyacinth flowers indoors.

With the right care you can have beautiful hyacinths blooming in your home no matter what season it is.
