Water the bulbs well following planting. This will help settle the soil in
the planting bed plus provide needed moisture for the bulbs to start
bulbs must root before cold weather. Avoid overwatering at planting
time, since this can result in bulb rot.
Average spring conditions should provide enough moisture for your bulbs.
However, if the weather is unusually hot and dry, a weekly deep soaking
will produce larger, longer-lasting blooms. For both spring and summer bulbs,
start watering when the flower buds first appear on the plant if the soil
is dry. Remember that the bulbs may have been planted 15 to 20 cm deep, and
the water needs to soak to that depth. Through the bud, bloom and early
foliage stage, add about 2-3 cm of water per week, if this amount has not
been supplied from rainfall. Water with a soaker hose to keep water off the
bloom. Shallow-planted bulbs will rot quickly if overwatered in the heat of
