Planting and Caring for Flower Bulbs
There
is nothing quite as welcome as those beautiful spring flowers
that seem to emerge from nowhere to welcome the arrival of
spring. Bulb type flowers are really unique plants, because they
spend most of their days resting quietly beneath the surface of
the soil. Then right on schedule, up they come, full of bloom
and vigor, and then almost as fast as they came, they go. Except
for the green leafy part of the plant that tends to linger
longer than we would like them to.
Despite their
short bloom time and unattractive foliage after the blooms are
gone, they are still a wonderful addition to any landscape. But
how should you care for them? First let’s talk about how to
use them in your landscape. Flowers of all kinds are best when
planted in groupings. Many people buy 25 or 50 bulbs and just go
around the yard planting helter skelter. That’s fine if
that’s what you want, but when planted that way they tend to
blend in with the landscape and really don’t show up well at
all. When you plant them in large groups they are a breathtaking
showpiece.
In the early
spring start thinking about where you would like to create a bed
for flower bulbs. Prepare the bed by raising it with good rich
topsoil, and if at all possible add some well composted cow
manure. Do this in the spring while you are in the gardening
mood, you may not be in the fall. Over the summer fill the bed
with annual flowers to keep the weeds down, and to pretty up
your yard for the summer. Come fall all you have to do is pull
out the annuals and plant your bulbs to the depth recommended on
the package.
If you think you
could have a problem with squirrels digging up the bulbs and
eating them, you can also wrap the bulbs in steel wool, leaving
just the tip of the bulb exposed so it can grow out of the
little wire cage you’ve created. Or you can just plant the
bulbs and then cover the bed with chicken wire or plastic
fencing until the bulbs start to grow in the spring.
When the bulbs
come up in the spring and start blooming, you should clip off
the blooms as they start to wither. This keeps the bulb from
producing seeds, which requires a lot of energy, and you want
the bulb to use all of its available energy to store food in
preparation of the bulb’s resting period. Once the bulbs are
completely done blooming you don’t want to cut off the tops
until they are withered and die back. The million dollar
question is how to treat the tops until that happens.
Many people bend
them over and slip a rubber band over them, or in the case of
bulbs like Daffodils tie them with one of the long leaves. This
seems to work because it is a very common practice among many
experienced gardeners. However, Mike is about to rain on the
parade.
I strongly
disagree with this theory because back about 6th grade we
learned about photosynthesis in science class. To recap what we
learned, and without going into the boring details,
photosynthesis is the process of the plant using the sun’s
rays to make food for itself. The rays from the sun are absorbed
by the foliage and the food making process begins. In the case
of a flower bulb this food is transported to the bulb beneath
the ground and stored for later use.
So basically the
leaves of the plant are like little solar panels. Their job is
to absorb the rays from the sun to begin the process known as
photosynthesis. If we fold them over and handcuff them with
their hands behind their back, they are not going to be able to
do their job. It’s like throwing a tarpaulin over 80% of a
solar panel.
In order for the
leaves to absorb the rays from the sun, the surface of the
foliage has to be exposed to the sun. On top of that, when you
bend the foliage over, you are restricting the flow of nutrients
to the bulb. The veins in the leaves and the stem are a lot like
our blood vessels. If you restrict them the flow stops.
You decide.
I’ve presented my case. Bending them over seems to work, but
I’ve spent a lot of money on my bulbs. I want them running at
full speed. What I do is clip the blooms off once they are
spent, and just leave the tops alone until they are yellow and
wilted. If they are still not wilted when it’s time to plant
my annual flowers, I just plant the annuals in between the
bulbs. As the bulbs die back the annuals tend to grow and
conceal them. If one shows through I clip it off. It seems to
work well for me. |
