gth to tender leaves
and buds.
For the fungus mildew, half an ounce of sulphide of potassium mixed in a
gallon of water and applied by a syringe is recommended (Wright).
Finely-powdered quick-lime mixed with sulphur (double the quantity of
the former), and distributed by a special bellows (see before, page 39),
is also said to be a good remedy.
ORCHARD HOUSE
For dimensions see under pears. Plums are best in pots or tubs, as they
can be taken out when at rest. They are very liable to attacks from
aphides, but the insecticide for pears in pots is good also for plums.
The house must be fumigated, and the trees syringed on the least
appearance of aphis. Place the pots on bricks (_v._ pears). When growth
is being started the temperature should be from 45 deg. at night to 50 deg. by
day. Soft or tepid water should be given freely. Fumigate again just
before the flowers come out. As the buds increase, raise the temperature
5 deg. to 10 deg. and syringe once or twice a day with tepid water. But a dry
atmosphere is important while the trees are in flower. Admit air as well
as bees in the forenoon, and pass a camel-hair or light brush over the
flowers about the middle of the day. When the fruit is set, syringe at
least once a day; if the weather is hot, twice or even three times a
day, and give all the air possible. Thin the fruits (if the crop is
large) with scissors; mulch and feed with weak liquid manure (see
pears). The shoots must be pinched if the trees are of any age, at the
fifth or sixth leaf. Not much heat is needed generally, but when the
stoning period is passed, the ripening process may be hastened by a
higher temperature. The house may be closed at an earlier hour if
necessary. Avoid extremes. As the fruits ripen, cease gradually to
syringe, but keep the house moist by sprinkling water over the paths,
etc. Choose the choicest dessert sorts: Early Transparent, Dennistoun's
Superb, July Greengage, Jefferson, Count Althann, Coe's Golden Drop,
Guthrie's Late Green, Angelina Burdett, Bryanstone Gage, and Golden
Transparent; and if darker colours are desired: Early Prolific, Belgian
Purple and Czar. Bryanston Gage was recommended by the R.H.S. in 1892,
and is a very richly-flavoured dessert variety, but is not a good
cropper in the open, and needs a wall or house.
DAMSONS
are often very valuable, and also make good outside hedges. Bradley's
"King of the Damsons" is the best. The fruit is large, the tree
