Thin out to 2 ft. apart. They may also be increased by shoots torn
from the stems of old plants. As well as flowering early in spring,
they often bloom in the autumn. Height, 1-1/2 ft.
Walnuts.--The Nuts for raising young trees may be planted at any time
between October and the end of February, 3 in. deep and 1-1/2 ft.
apart. Train to a single stem 8 to 10 ft. high, removing all the side
branches as soon as they make an appearance. The following year they
may be planted in their permanent position, which should be high,
yet sheltered from frost. Two of the best tall-growing varieties are
Thin-shelled and Noyer a Bijou. The Dwarf Prolific makes a good bush
tree.
Wand Plant.--See "Galax."
Wasps.--To destroy Wasps rinse a large bottle with spirits of
turpentine, and thrust the neck into the principal entrance to their
nest, stopping up all the other holes to prevent their escape. In
a few days the nest may be dug up. The fumes of the spirit first
stupefies and eventually destroys the insects.
Water-cress.--Sow in prepared places, during spring, in sluggish
brooks and moist situations; or it may be grown on a shady border if
kept moist by frequent waterings. It may also be grown in a frame in
September from cuttings placed 6 in. apart, sprinkling them daily, but
keeping the frame closed for two or three weeks, then watering once a
week. Give all the air possible in fine weather, but cover the frame
with mats during frosts. It is best when grown quickly.
Watsonia.--Plant the bulbs during January in sandy loam with a little
peat. They flower in April. Height, 1-1/2 ft.
Weeds in Paths.--These may be destroyed by strong brine, applied when
hot. Or mix 1/2 lb. of oil of vitriol with 6 gallons of water, and
apply, taking care not to get the vitriol on the hands or clothes.
Weigelia.--Free-flowering, hardy, deciduous shrubs, the flowers being
produced in profusion along the shoots in April, and varying in colour
from white to deep crimson. The plants will grow in any soil, and
require no special culture. All the varieties force well, and may be
increased by cuttings. Height, 6 ft.
White Scale.--See "Scale."
Whitlavia.--A hardy annual, needing no special treatment. It may be
sown in autumn, and protected during winter in a frame, or it may be
raised in spring in the open ground, where it will bloom in June.
Height, 2 ft.
Whortleberry.--See "Vaccineum."
Wigandia Caraccasana.--A stove deciduous shrub which thrives best in a
mixture of loam and peat. Cuttings in sand will strike if placed under
