January
- Check
stored bulbs and dahlia tubers. Discard the soft or rotted ones.
Sprinkling with water will plump up shriveled tubers.
- Water
overwintering geraniums and fuchsias just enough to keep them alive.
- Spray
cherry trees for bacterial canker. Apply dormant spray to apples and
pears.
- Apply
a dormant spray of lime sulfur on roses.
February
- When
soil becomes workable, prepare vegetable gardens for planting.
- Plant
peas in well-drained soil.
- Prune
fruit trees when the temperature is above freezing.
- On
mild days, plant bare-root roses, berries, grapes, kiwis, and fruit trees.
- Pull
mulch partly away from emerging bulbs and perennials. In mid-month, hunt
hidden slugs.
- Start
broccoli, cabbage and cauliflower indoors.
March
- Prune
and fertilize summer blooming clematis.
- Divide
perennials that will bloom after mid-June.
- Trim
heather and heaths after blooming, just back to below the point where
blooms form.
- Fertilize
established roses when they begin to leaf out.
- Bring
over-wintering fuchsias and geraniums out of dormancy. If needed,
put fuchsias in larger pots with fresh soil. Check for circling or damaged
roots.
- Apply
dormant spray on cane berries before or just after buds swell.
- Spray
peaches and nectarines with lime sulfur to control peach leaf curl.
- Control
slugs around newly planted seedlings.

blueberries, blackberries and raspberries with 5-10-10 fertilizer.
April
- Remove
and destroy tent caterpillar larvae and nests.
- Knock
aphids off roses with a stream of water.
- Set
out transplants of hardy annuals such as primroses, dusty miller and
pansies. Direct sow snapdragons, sweet alyssum, cornflower, clarkia,
calendula, larkspur, and Shirley poppy.
- Plant
dahlias, ranunculus, gladiolus, iris and cannas.
- Dispose
of fallen camellia blossoms to control the spread of botrytis or petal
blight.
- Control
brown rot on nectarines, apricots, peaches and cherries.
- Control
spittlebugs, aphids and slugs on strawberries.
- Protect
dogwood trees from anthracnose.
