The LILY NOOK
Guide to the Growing and Culture of
These lilies are hardy to zone 2 and very easy to grow. They come in all
shades and color combinations. These hybrids multiply rapidly and bloom over a
long season. The flowers can be up-facing, side-facing or down-facing, vary in
height and flower mid season.
These dainty flowered ones are fast becoming popular, with as many a 50
flowers on tall erect stems with whorled leaves. These lilies often take a year
to settle in and are known to sulk the first growing season, sometimes not
showing any presence until the next growing season. Once established in the
border or garden they can be left alone for many years. They are the only lilies
that prefer dappled shade.
Orientals, Trumpet and Aurelians:
These varieties are the most exotic and showy of all lilies. These varieties
multiply more slowly. They can be grown on the prairies but it takes a little
more effort on your part of amending the soil and providing heavier winter
protection of straw, leaves and peat moss. We find that Spring planting of these
groups allows them to settle in and are more apt to make it through the winter.
Protecting them from the first frosts, by covering them with a cardboard box
will allow the bulbs to mature more fully for the following year. These large
beautiful scented flowers that bloom late summer will be well worth the extra
effort needed. For this reason we do not offer replacements for failure to grow
on these varieties.
Orienpet - Longipet - L.O. Hybrids:
These lilies are breakthroughs in the lily hybridzing world giving improved
hybrid vigor and large showy flower. They are proving more hardy then their
parents, the orientals, trumpets and longiflorums. However these should be mulch
to aid in over wintering in cold climates. Spring planting of these groups
allows them to settle in and are more apt to make it through the winter.
Species lilies require specialized care due to their different natural
growing conditions through-out the world. Anyone endeavoring to grow these
varieties needs to research their growing requirements. Species bulbs for the
most part are smaller than hybrid varieties, but will produce good quality stems
and blooms. Their delicate, beautiful flowers will be well worth the effort
Lily bulbs are never completely dormant so they must be planted as soon as
possible. If for some reason you are unable to plant your bulbs immediately,
then keep them refrigerated until you can plant them. Store them in a poly bag
in slightly damp peat moss in the crisper of the fridge.
(1) Location: It is important to choose the right location. Lilies
require direct sunlight for part to all of the day. They also require "Well
Drained Soil". A medium sandy loam soil with a reasonable amount of humus is
ideal. Peat moss can also be added. Heavy soils can be lightened with course
sand and peat moss. If using manure make sure it is well rotted and use as top
dress only, otherwise it can cause damage to the bulbs by lowering their disease
(2) Planting: Most lilies should be planted to a depth of 6” and
12-16”apart. Trumpets and orientals should be planted to a depth of 8” for extra
winter protection. Place your lily bulb with its roots down and scale points up.
A little bone meal may be added at this time. Cover with your soil mixture. Pack
the soil in well around your bulb. It is important to thoroughly water your
bulbs in after planting, so the soil settles around the bulb to prevent any air
pockets. Lilies make a nice show if they are planted in triangular groups of 3
(3) Watering: They do not require daily watering but when watering be
sure to water deeply enough to reach the bulb. Avoid wetting the leaves.
Excessive watering will cause your bulb to rot.
(4) Fertilizing: A light to moderate fertilizer (20-20-20) can be applied
just before flowering and after blooming is completed to keep bulbs healthy.
Do not fertilize too late in the fall as bulbs can become too soft and rot.
(5) Labelling: It is wise to mark each bulb planted with a stake and a
weather resistant marker, so as not to damage the lily shoots in the spring when
working around your lily bulbs.
Bulbs may be planted singly in a 6" pot or in
groups of 3 in a larger pot, allow for 4-6” of soil above the bulb. Use a
commercial potting soil mixed with 1/3 peat and 1/3 perlite or sand to allow for
good drainage. A regular application of fertilizer as well as repotting every
year with fresh soil is recommended. Because lilies are never completely
dormant, extra care for winter must be taken. Place pots in a root cellar or
remove bulbs and store in plastic bags with peat moss in a fridge. Bulbs should
not get below freezing.
Do not remove or cutback the spent stalks until complete dieback has
occurred in the fall or it could weaken the bulb. Fall is the best time to
divide your clump of lilies. This is advised to be done every 4-5 years. Use a
spading fork and carefully lift the bulbs from underneath, being careful not to
damage the bulbs. Separate the larger bulbs and replant as soon as possible into
freshly amended soil. Plant the smaller bulblets 2” deep.Asiatic Hybrids:
When cutting a stem, leave at least one third of the stalk to feed the bulb so
it can mature properly for the following year. The best time to cut is early in
the morning. Place in warm water and enjoy their beauty and fragrance!
To prevent staining the pollen should be removed from the anthers of cut flowers. If staining occurs, brush access pollen off lightly and treat the stain with any stain remover or dish detergent . Launder as usual.
Diseases and Pests:
Botrytis - is a fungus disease, which affects the leaves of lilies,
caused by excessive moisture and warm temperatures. The first signs can be brown
spots on the leaves. In severe cases the whole leaf and stem can become infected
and the whole plant decay and collapse. Injury to plants, like frost or hail
will make it easier for Botrytis spores to enter the leaf; spraying is strongly
advised very soon after injury. The disease is not carried by the bulb so it
will not affect flowering the following year. In early stages of infection, if
possible remove noticeable spotted leaves. Spraying is highly advisable, and is
only effective when foliage is dry. A copper spray can be used or natural
remedies such as a baking soda mixture (1 tbsp. per gallon of water) sprayed
weekly on the foliage during wet periods. Good air circulation will help prevent
a outbreak. Planting lilies some distance apart will also control infection. In
the fall clean up and burn dead stems and leaves.
Basal Rot - This fungus invades the bulb through the roots and basal
plate. The symptoms on the growing plants are usually premature streaky
yellowing of the foliage. The disease can become present in warm moist soils. As
a preventive, avoid over-watering during warm summer months and provide good
drainage. As for infected bulbs, you can remove the infected scales, dip the
bulbs in a fungicide solution.
Blue Mold - Because lilies have a high sugar content, bruising or
mechanical injury can cause a penicillin mold to form on the injured part of the
bulb. This is harmless to the bulb and can be carefully removed. The bulb can be
dusted with a fungicide powder and planted as usual.
Virus Diseases - Lily viruses are transmitted largely by aphids. Visible
evidence of virus could be all or some of the following; Irregular mottling and
flecking on the leaves, reduction in plant size and height, distorted growth,
color-breaking in the flowers and leaves, brown ring patterns on bulb scales.
A few tips to help control viruses are: Destroy clumps of lilies that show
severe infection, insuring that all bulbs and scales are discarded. Remove
plants showing infection early in the season. Avoid planting lilies next to
other host plants like Tulips or lilium tigrinum (also known as the Tiger Lily).
Control aphid infections with the use of insecticides.
Lily Beetle - Long prevalent in Europe, the lily beetle (Lilioceris lilii)
has been reported in eastern North America. The larvae and adult beetles feed on
the leaves of lilies. The larva is a yellow grub with a dark head, covering
itself in dark, slimy excrement. The adult is up to 8 millimetres (0.25 inch)
long and bright scarlet with black legs and antennae. Both life stages have
voracious appetites and soon devour entire plants. The eggs are laid on the
underside of the foliage. The following controls are effective: Spray plants
with contact and systemic insecticides; both are effective. Drench soil with a
soil insecticide to kill the mature larvae that live just under the soil surface
in winter. Also, avoid transporting infested soil to other sites. Catch adult
beetles between the fingers and smash them. The lily beetle has only appeared in
a few places on this continent, and with care, it should be possible to prevent
any lasting infestation.
We guarantee our bulbs to be true to name, and healthy upon arrival. However we
cannot be reasonably held responsible for any bulb loss due to circumstances
beyond our control, such as unusual weather conditions i.e. sudden deep freezes
with out snow cover, or prolonged rainfall, soil conditions, cultivation or lack
of care. Guarantee is for garden planted bulbs, not container planting, or any
other types of winter storage in which we have no control.
