Hyacinths produce showy, fragrant blooms in the
early to mid spring. They arise from a bulb planted
in the autumn and have the ability to continue for
years while producing bulblets to expand their size.
Like most bulb plants, hyacinths
must have good soil drainage to prevent fungal rot
diseases. They do not do well in extremely dry
soils. Although they will still perform in a
slightly shady site, they would prefer full sun.
The general rule for
that they should be planted in a hole about 2-3
times their height. Therefore, if the bulb is 2
inches tall, you need a 4 inch deep hole in
soils and a 6 inch deep hole in sandy or loamy
soils. Hyacinths are generally planted in the fall.
When the foliage appears in the
spring, you can topdress the bulbs in the garden
with a complete fertilizer. Remember that it takes
time for the fertilizer to penetrate the soil down
to the bulb and is only useful to the plant as long
as the leaves are still green.
Root Rot - This causes a deterioration of the
bulb and eventual death of the plant. Generally this
type of rot only occurs in soils with poor drainage
that allows the bulbs to be soaked in water for long
periods of time.
As long as the hyacinths are
rated as hardy for your particular climate zone,
they should need no special winter care. Leave them
in the ground and enjoy them the next spring.
