How to grow Lilies
There are many kinds of lilies with some
differences in requirements for growth. By selecting an assortment
varieties the home gardener can have a succession lily blooms from
June through September.
SOIL AND SITE: Good drainage is
essential for all lilies. If the soil is not naturally well drained,
gravel should be placed in the bottom of the bed. The soil must also
be granular and well supplied with plant food nutrients. Some types
of lilies require a damp location. The European Lilies thrive best
in alkaline soil. The American Lilies and those from Himalaya and
Japan seem to prefer acid soil. Most lilies seem to succeed in full
sun, although partial shade, especially at midday, preserves the colors
and prolongs the flower-ing season. Lilies also want lots of air around
them. They shouldn't be crowded.
PLANTING: The soil should be dug
down to 1 foot and Fertilizer mixed and worked thoroughly into the
soil. Sand, leaf mold, peat moss, or other material may be needed
to adjust the soil, and should., be mixed in at this time. In most,
sections of the country the Ameri-can-grown bulbs should go in the
soil about mid-October. The Madonna Lily is usually planted in August
or early Sep-tember. Imported bulbs which arrive too late in the fall
can be planted in heavily mulched soil or potted up and kept in the
cold frame. The size of bulb, type of soil, and manner of root growth
are all factors in planting. A general rule is to set bulbs three
times their own depth. Bulbs planted in sandy soils should be 2 inches
deeper than in clay soils. Space small lilies 6 to 7 inches apart
and larger ones 1 foot apart.
SUMMER CARE: Keep soil free of weeds
by shallow cultivation. Take care not to break the tender growth.
A summer mulch of leaf mold or peat moss will keep weeds out, conserve
moisture, and keep the root cooler. If dry weather comes in July or
August, soak the planting down to 6 inches once a week. Feed Fertilizer
Complete Plant Food at least once during the summer, using 1 pound
for each 25 square feet of bed. Stake when necessary, being care-ful
not to drive the stake through foliage. After blooming, the plants
need the leaves to manufacture food reserves for storage in the bulb.
GROWING FROM SEED: Lily seeds may
be sown as soon as they are ripe. Sow seeds in cold frame and allow
them to grow until bulbs are formed. Keep seedlings shaded the first
year.
DISEASES: Lily mosaic is a preva-lent
and virulent disease. When it appears on a plant there is only one
thing to do-dig up the plant and burn, thus keeping it away from healthy
plants. This disease is carried by a virus and a fungi-cide will not
give protection. There are several fungus diseases, such as botrytis
blight that is com-monly found on lilies, which can, be controlled
by regular preven-tive dusting.
