Hyacinths are ideal for spring bedding, being relatively short they are perfect for the front of borders and for containers.

Hyacinths should be planted in the autumn in a well cultivated, well-drained soil. A good root system is essential, they enjoy a cool temperature and even moisture in the early stages after planting. Plant the bulbs 10cm (4″) deep and 5-8cm (2-3″) apart. Shallow planting can cause the bulbs to split and produce smaller flowers after the first year. Hyacinths in the border can generally be left undisturbed for three to four years before they will need division.

Caring For Hyacinths in Spring

As the Hyacinths emerge in the Spring some varieties may require staking to prevent them from flopping over in heavy rain. The stake should be inserted along the stem and pierced straight into and through the bulb. Tie to the stem just below the flower head.

Growing Hyacinths in Pots and Containers

Hyacinths do equally well planted in pots and containers for the patio but it is important to use good quality soil. Choose a sunny spot and remember that it is essential during dry periods in the growing season that they are sufficiently watered. Lack of water will result in stunted and shrivelled flower heads. In the case of a severe frost give them some protection, covering the container with a plastic liner is one easy option.

Growing Hyacinths For Indoors

Excellent results can easily be achieved provided a few basic rules are followed. The first essential is to develop a good root system as this must support the plant throughout its life. This is achieved by cool temperature and even moisture.

Preparing Hyacinth Bulbs for Potting

The slower the process the stronger and longer lasting the plants will be. Use good quality bulb fibre and avoid soilless compost, this can become very compact and is difficult to keep evenly moist. Bulbs should be planted so that the top quarter of the bulb is visible above the soil line. Make sure the container is well watered. Potting should not be too firm, otherwise there is a tendency for the bulbs to push themselves out of the compost as they form their roots. If the hyacinths grow secondary shoots, these may be cut off at the lowest point.

Method 1 – Place Hyacinth Bulbs in a Plunge Bed

The best method is to pot them and place the pot or bowls in a plunge bed against a shady wall or fence and cover with 15cm of soil or compost. The ideal temperature in the pit should not exceed 7-10º C.

If ornamental bowls are used they may be wrapped in newspaper, this will eventually become soft and the top growth will be able to penetrate it without any harmful effect.

Method 2 – Place in a Dark Place

Alternatively, the bowls may stand in a cool dark place such as a cellar or garage. The ideal temperature in a dark place is 7-10º C.

If this method is used it is essential to keep the soil evenly moist.

When to Bring Hyacinths Into the Light

Do not remove until the flower bud stands well out of the neck of the bulb, the shoots should be 6-8cm high. If removed too early the bud will become stuck and growth will cease. Whilst at this stage remove the bowls to the light. Keep in a temperature not exceeding 21º C. and away from all forms of direct heat.
