SUMMER FLOWERING BULBS IN THE HOME LANDSCAPE
|
|||
|
|
|||
|
The addition of summer flowering bulbs to the home landscape adds not only beauty but
|
|||
|
interest. These plants have a particular form as well as brilliant, clear colors. They
|
|||
|
are easy to grow and can be saved and planted year after year. They can be planted
|
|||
|
directly in beds or may be grown in containers. A wide choice is possible in the kinds
|
|||
|
of summer bulbs available.
|
|||
|
|
|||
|
Tuberous begonias:
|
|||
|
available in beautiful red, pink, orange, salmon, yellow or white flowers attaining a size of 12 to 14 inches in diameter.
|
|||
|
The tubers can be planted in flats or pots in March or April to get a faster start, or they can be planted directly in the garden about
|
|||
|
mid-May.
|
|||
|
|
|||
|
If starting them early, use shallow flats or pots that have been filled with coarse
|
|||
|
peat moss. Press the tuber into the peat moss 3 to 4 inches apart with the concave side
|
|||
|
up. Place the flats or pots in a dark room such as the basement at 65 deg. to 70 deg.F.
|
|||
|
As the pink shoots start to develop, add more peat moss so it covers the tubers and move
|
|||
|
them to a sunny window. Keep the peat moss moist, but do not overwater the
|
|||
|
tubers as they rot easily. Fertilize the young plants with a liquid fertilizer
|
|||
|
every two weeks according to the rate on the container.
|
|||
|
|
|||
|
About the middle of May, plants as well as unsprouted tubers can be planted in the
|
|||
|
garden. Select an area that is well drained and partially shaded. Set the tubers
|
|||
|
in the ground so they are just covered and no deeper as they are subject to rotting.
|
|||
|
To allow for plenty of growing space and air circulation, set the tubers or plants
|
|||
|
18 to 24 inches apart. It may be necessary to stake the young plants as many of the
|
|||
|
larger growing cultivars (varieties) become top heavy bloom.
|
|||
|
|
|||
|
Apply a fertilizer such as 4-16-16, 5-10-5, 5-10-10 or 5-20.20 at the rate of 3 to 4
|
|||
|
pounds per 100 square feet at monthly intervals. Water when the soil starts to dry,
|
|||
|
preferably in the morning or early afternoon. This allows the foliage and flowers
|
|||
|
to dry before nightfall and reduces chances of disease.
|
|||
|
|
|||
|
After the frost has killed the foliage, the tubers must be dug, the foliage removed and tubers dried for a few days. Store in peat moss or
|
|||
|
sawdust in boxes or other containers but not plastic bags. Place in a storage space that is dry and where
|
|||
|
the temperature is maintained around 50 F. Do not allow the tubers to freeze.
|
|||
|
|
|||
|
Canna: commonly used years ago where a tall plant with bright red color was
|
|||
|
needed. This plant had luxurious green foliage to support the flower. The plant seemed to diminish in popularity but has begun a revival due
|
|||
|
to new cultivars that offer not only red flowers but pink, orange, yellow and cream. Some even have red
|
|||
|
or bronze foliage. Some cultivars are tall, reaching a height of 7 to 8 feet, while others are a maximum of 18 inches.
|
|||
|
|
|||
|
The rhizomes (underground stems) may be started early, such as with begonias, or
|
|||
|
they can be planted directly in the garden. Usually they are planted directly in
|
|||
|
the garden about the middle of May. Select a spot that is well drained and receives full sunlight. The rhizomes should be planted a couple of
|
|||
|
inches below the surface and 18 to 24 inches apart. Water thoroughly after planting and begin fertilizing as soon as the shoots come through
|
|||
|
the ground. Use a dry complete fertilizer such as 4-16-16, 5-10-5, 5-10-10 or 5-20-20 at the rate of 3 to 4 pounds per 100 square feet.
|
|||
|
Apply once a month during the growing season and water thoroughly after application. Water the plants when the soil begins to dry and
|
|||
|
stake if necessary.
|
|||
|
|
|||
|
Once the foliage has been killed by frost, the dead tops should be removed and the
|
|||
|
rhizomes dug. Be careful not to damage them. Remove the soil and let the rhizomes
|
|||
|
lie on the garage or basement floor for a few days to dry. Then store them in dry
|
|||
|
peat moss or sawdust in boxes, bushel baskets or gunny sacks. Select a spot in the
|
|||
|
basement or where they will be dry and can be kept at 45 to 50 F. Do not allow them
|
|||
|
to freeze.
|
|||
|
|
|||
|
Gladiolus: grown for their magnificent flowers, which come in all colors. There
|
|||
|
are large flower types as well as small. They can be used as background plants in
|
|||
|
the garden or as cut flowers for inside the home. If care is given to a planting
|
|||
|
schedule, flowers can be available from early summer until frost. Therefore, it is
|
|||
|
advisable to separate the corms into various planting dates so flowering can be spread
|
|||
|
out.
|
|||
|
|
|||
|
The first corms can be planted as early as May 1. Set the corms 4 to 5 inches deep
|
|||
|
and 5 to 6 inches apart. If they are grown in rows, allow 36 inches between the rows.
|
|||
|
In two wee%s, plant the next group of corms and continue this procedure until the
|
|||
|
last of July. By so planting, flowers will be available almost anytime during the
|
|||
|
summer. As soon as the plants are 6 to 8 inches tall, apply a complete dry fertilizer
|
|||
|
such as 4-16-16, 5-10-5, 5-10-10 or 5-20-20 at the rate of 3 to 4 pounds per 100
|
|||
|
square feet. This is the only fertilizer that will be needed during the growing season.
|
|||
|
Water the plants thoroughly when the soil starts to get dry.
|
|||
|
|
|||
|
After the foliage has dried in late summer or autumn, dig the corms, remove the soil and
|
|||
|
snap off the dead tops. The old corm or "mummy"may also be removed at this time
|
|||
|
if still present. Spread the corms out on the garage or basement floor and allow to
|
|||
|
dry for three or four days. Place the corms in boxes with dry peat moss or sawdust.
|
|||
|
If a large number of corms are involved, make some boxes that are 3 to 4 inches deep
|
|||
|
with bottoms made of hardware cloth. Store the corms in a dry, cool place at a
|
|||
|
temperature of 35 to 40"F. Check them periodically during the winter for signs
|
|||
|
of rotting or rodents.
