"HOLLOW-CORING" was an old trick of the hyacinth growers' trade; it's a way to persuade a single bulb to produce five or six separate flower heads. Tom Maxey, managing director of Groom Bros, bulb growers of Spalding, learnt the technique in Holland, where he was as an 18-year-old apprentice.

The hyacinth bulbs are lifted and dried in July. Only the biggest, 7ins or more in diameter, are suitable for treatment. "You turn each bulb upside down," he explained. "Then you use a special knife to cut out the base of the bulb - you leave the roots intact."

Treated bulbs are stored in special chambers at 20C (68F). The warmth encourages them to make new basal growing points. In October the bulbs are taken out of storage, planted and grown on until the following July. Then they are lifted again, graded and kept in the same warm stores until they are sold. They are generally available from mid-August onwards. If you plant them in late August or early September in pots, they will bloom indoors by the end of January.

These specially treated hyacinth bulbs cost pounds 3.67 each from Groom Bros, Peck's Drove Nurseries, Spalding, Lincs PE12 6BJ (01775 722421).
