THE DAHLIA
Plant Dahlias in May, or June,
or July? Why should we defer planting if it can be done in May, and will not
May give better results than late June? The time to plant Dahlias is a much
debated questions among the experts even. There are probably many factors
that control the answer. The matter of location is a big factor. For
instance, it is beyond question that in some sections it makes not the
slightest difference whether the roots are set out in early May or early
July. Where early May planting can be done, the plants begin to flower about
the middle of July, and under disbudding continue bloom8ing until frost, yet
in a neighboring district the best results will accrue from planting as late
as it is possible to keep the plants out of the ground. Many good Dahlia
enthusiasts devote part of the Fourth of July to the ceremonial setting out
of Dahlia roots. |
Why? Because in some sections the
wood from early growth becomes so hard that it cannot continue the succulent
development - that is essential for the production of good flowers. In other
words, in certain localities late planting tides the plant over the early
August drought so that it continues a normal, succulent growth later,
whereas by early planting under such conditions, the early August drought
produces a fatal hardening of the tissues. It matters not how thoroughly the
ground is cultivated, nor how frequently it is done, Dahlia plants stop
growing and the main stalk becomes too hard in sections where the late July
and August drought is accompanied by excessive heat. Under such
circumstances flower development is made impossible unless the plants are
then cut back hard; that is to say, clear to the bottom pair of leaves so
that the subsequent development of the plant is from soft, young growth made
from the base.
Fresh succulent growth is essential for the production of Dahlia flowers.
If you must plant your Dahlia roots in May (and it is very hard not to do
so) if you have not had success with them of late years try the new practice
this year of cutting them back during the early part of July. |
Green plants or dormant roots?
Again a matter of opinion. Many experienced growers say that there is no
advantage one way or the other, while others claim that the green plant—that
is a plant that is rooted from a cutting taken in heat in spring—will give
exhibition quality flowers. The Dahlia has long been a favorite garden plant
in England. Indeed it has been largely developed to its present perfection
in that country, and there nothing but green plants are used when flowers
are wanted.
My own experience during the past few seasons in Pennsylvania has
led me to favor green plants, but this statement needs qualifying to the
extent of saying that as far as the ultimate quality of the flower is
concerned the results are the same. The cutting back system has one
disadvantage, that is the inclination of some plants to throw out numerous
suckers from the old root after the original top has been cut back. This, of
course, is the result of stimulating into growth the latent eyes which under
normal conditions would have remained practically dormant, but which the
check of cutting back stimulates into action. These must be watched for and
removed, cutting them well below the soil level. This is important in order
to get air and light freely circulating around the growing stems. |
