PREPARATION FOR WINTER
BY GLADYS JEURINK
Different plants need different care to prep them for winter. 1.
The Camellia is a late winter bloomer that needs acid soil and a
fair amount of shade. They also tend to grow tall and skinny so I pinch
out the top to try to make it branch and sprinkle a few sulfur pellets
on the soil to lower the pH. It also needs to be in a loose potting soil
that is damp but not wet.
After the buds are formed try not to move the plant as it may just drop
all of them. 2.
Azalea’s are small shrubs. Some are hardy but the florist type
Azalea usually is not. The most common florist type is the Indian Azalea
(Rhododendron simsii), hardy to zone 8-12. It is another plant liking
acid soil so as I bring it in I scratch a tablespoon or so of sulfur
granules (not dust) in the top of the soil. It also likes humidity so
having several plants close to each other helps. To keep a Christmas
gift in bloom requires that it be kept cool, moist but not wet, and
brightly lit but not in direct sun. Too much sun or too little water
will cut short the blooming season. 3.
My Angel Trumpets are in 20 inch pots in an area protected from
as much wind as possible as it tears the long (12 inches to 14 inches)
trumpets. The plant blooms for a time, then takes a rest period when it
grows and then blooms again. In a long summer one can get a number of
bloom periods. They can be
cut back and placed in a cool room for winter but that huge plant, plus
the heavy pot are not easy to move around. The last few years I have
taken cuttings with no flower buds and as small as practical.
I have a yellow and a pink and may start several of each but
usually they have little trouble rooting. I do use a rooting hormone.
In the green house they grow very fast so I try to have them very
small to start. 4.
Peruvian Daffodils (Hymenocallis narcissiflora) are not hardy in
Nebraska and must be dug before a frost. I cut the tops off, separate
the loose soil, and put them in boxes of vermiculite in an unheated room
in the basement. Bulbs need to be dry in winter to avoid root rot. They
are also known as Isemene, or Spider Lilies.
As you might have guessed they are natives of South America.
They do well in florist bouquets so the growers plant bulbs
spread out over a number of weeks as they bloom almost immediately after
planting on stems about 24 inches long. The flowers are large (8
inches), white, with a large cup and 6 narrow petals (spider legs?).
When planting, the nose is just at the soil surface.
Mine grow in the very high shade of a cottonwood tree but not
near the trunk. Bulbs need to be dry in winter to avoid root rot. 5.
Another bulb to dig in the fall is the Giant Star of Bethlehem (Ornithogalium
thyrsoides). Books and catalogues say they grow 3 feet tall but mine
usually get 5 to 6 feet tall with slender 24 inch leaves.
There are no leaves on the flower stems that bloom from bottom
up, starting at 2 1/2 feet until it reaches 6 feet.
They are planted about 4 inches deep but in loose soil so are
easy to dig. Some of you
may have the short form (Ornithogalium nutans or Ornithogalium
umbellatum) that can become invasive as they are hardy here. They have a
single waxy white flower with a black center while the Giant has many
clustered on the stem and take a week for all of them to open.
Like the Isemene, the bulbs need to be in a cool, dry place in
the winter. Copyright 2015 |
