Black Leaf Forty is good. Formerly I was able to get a
solution called Nicotine, but I understand that is out of the
market now, and not to be had. I was told that it was mislabeled,
or misbranded, and the Government, as usual, stepped in and
stopped its sale. That other preparation was better than the
Black Leaf Forty. Then again, r use tobacco dust, cover the
ground, or lightly sprinkle it over the ground. I did not do it
this year, however. It has a tendency to choke the aphis. The
main secret of getting rid of them is to get at them good and
early. That is almost all that is necessary. If you do that,-you
will not have very much trouble.
Now, about planting time. A good many growers seem to
advise-that is, a good many nurserymen seem to advise-spring
planting for Wisconsin; I believe that is a mistake. The best
success I have had was from fall planting, strange to say. The
plants seemed to go through the following winter better than the
plants that were planted in the spring the year previous. Those
plants did not seem to get a good start, even though I gave them
an unusual amount of care. The situation is this, that the warm
weather comes on very fast, and we really have very few spring
days here; one day it is cold, and the next day it is hot, and from
winter you might almost say that we go into summer. That is
the reason, I believe, from my experience, that fall planting is
advisable. The plants have a better chance. A rose will grow
in cold weather. They set better, and you can buy better plants
in the fall, which is also an incentive. If you wait until spring
and order them, the chances are they may arrive very late, if not
too late, for the plants to get a good start, even though all other
things are equal. One of my friends has always made it a prac-
tice to plant in the fall. He has been very successful, and as
the result of his experience I have changed from spring to fall
Now, I believe that what I have said covers all of the essen-
tials. Of course, there are a few other little things that must
be taken into account, one of which is not mixing up the varieties
too much. And you do not want to plant a very vigorous plant
in front, and a less vigorous one in the back, and things of that
kind. Try to keep the varieties separate, if you possibly can.
It is better, and you will have better results.
