Plant hyacinth bulbs in glasses during October or early November and you should have fragrant blooms to welcome in the New Year. Be sure to buy ‘prepared’ bulbs, and not the cheaper garden hyacinths. Prepared bulbs receive special temperature treatment before they go on sale, which initiates flower bud development. You can choose from a range of flower colours, and grow them in either clear or coloured glasses of various shapes and sizes.

Fill each hyacinth glass with water to just below where the bulb’s base will sit, then put the bulb in place. Make sure it doesn't touch the water, but sits just above it. Place the glass in a cool (below 10°C), dark place for six weeks for roots to form.

Once the main shoot is about 7-10cm tall, move the glass into full light and watch the flower gradually develop.

Turn the glass around by a half-turn every day, to prevent the plant growing towards the light and toppling over. Top up the water as necessary.
