Enjoy the intoxicating fragrance of hyacinths and the dramatic blooms of amaryllis (Hippeastrum), 'Paper White' daffodils and other bulbs for Christmas and New Year. These bulbs are readily available and easy to grow in just a few months.
To be in flower for Christmas planting must be done ahead of time;
This method is the same for all forced bulbs, apart from the alternative ways mentioned below:
After planting, the bulbs need a dark and cool period (ideally 9°C/48°F) to encourage the development of a good root system.
This is an alternative method for growing hyacinths. The bulb should be slightly smaller in diameter than the vase so that it sits snugly in the vase. Fill the glass with water to the neck and then place the bulb in the top. The water level should be just below the bottom of the bulb. The plant can then be treated in the same way as potted hyacinths (below).
Your bulbs need to be at a certain stage of development before they can be brought inside for display. Here are some guidelines;
Bulbs such as Narcissus 'Paperwhite' and N. 'Bridal Crown' are not hardy in most parts of the UK, so are best allowed to dry off and stored for replanting in containers later in the year.
Allow hyacinths to die down naturally after flowering and then plant the bulbs in the garden at twice their own height.
Hippeastrum bulbs can be kept in active growth for a few months, then rested and brought into flower again.
The main reasons for poor results are:
