--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
glass and in heat. It flowers in April. Height, 10 ft.

Windflowers.--_See_ "Anemones."

Winter Aconite (_Eranthis Hyemalis_).--This is one of the very first
of flowers to bloom, being in advance of the Snowdrop. In the bleakest
days of winter this little flower covers the ground with its gilt
spangles. Plant in early autumn. Any soil or situation suits it, but
it does best in a light mould and a moist, shady position, or under
trees. Most effective when planted in masses. The tubers may remain
permanently in the ground, or they may be lifted and divided in
summer, as soon as the foliage dies down. Flowers are produced from
December to February.

Winter Cherry.--_See_ "Physalis."

Winter Heliotrope.--_See_ "Tussilago."

Wire-worms.--Before using mould for potting purposes it is advisable
to examine it carefully and pick out any Wire-worms that are in it.
For the border the best traps are small potatoes with a hole c
