THE GARDENING WORLD. 
dwarf-growing one, it would be worth your while 
getting a sufficient quantity of the tree Box to 
renew the edging. The operation might very 
well be performed in March. It might have been 
done with advantage about the end of September. 
Plum Trees Going Off. 
Please state what is the cause of my trees going 
off in this way, cuttings enclosed. Is this what 
is termed American blight? (Novice.) 
There is very little chance of getting American 
blight on Plum trees, as we have never seen the 
insect upon any of the stone fruits. The speci¬ 
mens you sent us must have been badly affected 
early in the year, and the young growing shoots 
must also have kept the insects on during the 
summer months. Very little is now left on the 
leaves except the excrement and the cast-off skins, 
and judging from these your trees must have 
been badly affected with the Plum Aphis (Aphis 
Pruni), which is exceedingly destructive to Plum 
trees during the period that the trees are making 
their young growth. We refer to the mealy 
aphis of Plums which has also another scientific 
name. You can recognise them, however, by 
their crowding together in dense clusters upon 
the under sides of the leaves, and by being more 
or less covered with a mealy substance secreted 
from their bodies. The juice which they excrete 
from the tubes at the end of their bodies is also 
of a very sticky nature, and this falling upon the 
leaves beneath them causes them to become black 
on the upper surface in a short time, owing to 
a fungus which grows on this sugary secretion. 
This will give you a clue to the enemy, but you 
will have to look for and attack it in the early 
part of the season, while the trees are still making 
their growth. You may expect to find them in 
May and June, and the sooner you attack the 
aphides before they have had time to render the 
leaves filthy the better. A ready method of 
getting rid of a. large number of them would be 
to cut off the tips of infested shoots that are not 
wanted for the increase of the tree. These should 
be burned and not thrown down where the 
aphides may pass into the winged state and fly 
back to the trees. The trees should be syringed 
by means of something that will sicken or destroy 
the aphides, though they are rather hard to kill 
on account of the mealy substance covering them. 
One simple wash .would consist in steeping, boil¬ 
ing, or infusing a pound of tobacco in two gallons 
of water, and adding a \ lb. of soft soap or Gis- 
hurst compound after it has been dissolved in 
hard water. After the solution becomes cool, 
and you have strained out the tobacco, the trees 
may then be rather forcibly syringed with this 
insecticide, making sure that it goes underneath 
the leaves, and as much as possible into the folds 
of those, which have been curled up by the agency 
of the aphides. If this operation is performed at 
the first appearance of the attack very few of the 
leaves will be rolled up, and the enemy will be 
more easy to exterminate. This could be done 
late in the afternoon of one day, and the trees 
washed with the garden engine or syringed next 
morning, applying the water forcibly. If the 
aphides are not all destroyed the operation could 
be repeated in the course of a day or two. After 
this is done properly the leaves will then keep 
their healthy condition till the end of the season.
