If you start before about the
middle of September (but the sooner the better), you can have flowering Hyacinth
bulbs for the house in flower at or just after Christmas. If you
can get them planted before November, then they will have a chance to start
growing before it begins to get very cold which will help them to flower all
the earlier, they'll certainly be up early in the new year and long before
the outdoor ones have woken up.
Plant - In containers,
borders or beds NOT naturalized in grass.
Depth - 5-8"
of soil above the top of the bulb, less in clay, more in sandy soils.
Depth in containers
- The top of the bulbs should emerge from the compost, broad and shallow
containers are most common and popular, but after much experimentation
I have found that container grown Hyacinths do much better in deeper containers
- a normally proportioned plant pot is fine. The deeper the roots go, the
higher the flowers and leaves seem to reach too. Moss can be used to cover
the bulbs from about half way up to almost the tip.
Cultivation - after
flowering, remove seed heads so not to waste resources, water once with
double strength liquid fertiliser, plenty of it to reach the bulbs and roots.
Leave leaves to die down
naturally - don't tie the leaves, cut them or otherwise damage them
in any way, this is when the bulb is built up again for next years flowers,
any interference will stop this and give smaller, weaker or blind flowering.
Leave at least 6 weeks for the leaves to do their job, if possible don't
touch them at all until they are completely brown and shrivelled and can
be pulled up with little resistance.
Container cultivation
- if the containers are to be brought indoors, grow them on somewhere cool
but sheltered an unheated greenhouse, conservatory or similar is ideal.
Let them grow as tall as possible before bringing them indoors as they may
get leggy and even not flower if brought in too early. They will last longest
in a cool but bright position. Support will probably be necessary.
After the flowers are over,
put them outside in a sheltered position and grow / water / feed as normal
for bulbs. They will not perform as well the next year, so don't even
bother trying, bulbs for indoor containers should be bought fresh each year.
When the leaves have died down, they can be left to dry out and planted
in the garden in the autumn as outdoor bulbs. They won't be very good
in year 2, but will be fine from 3 onwards.
