April: To Do
Oh, and if you really think that I actually do all of these
things, you are terribly confused. Sometimes I even (gasp)
do things that aren't on this list.
I can only guarrentee this list is accurate for the things that
I grow. I do not grow every item on this list. This list
is targetted to Sunset Zone 14,
specifically, and I think it is good for all of USDA Zone 9. In
addition, it is probably pretty accurate for USDA Zones 10-11.
April in Livermore is usually beautiful and warm. Last year, 1998,
it has been wet which is very unusual for us, and we had a frost on
or about April 15th.
General (or it never ends)
- Pests: Aphids are attacking! Hose them off
with water. You can also purchase ladybugs, or try the
chemical route: insecticidal soap, diazinon, malathion, or
orthene. I recommend against using any of the chemical on
plants you intend to eat. Be sure to read all warning
labels.
- Water weekly.
- Weed.
Trees, Shrubs, and Vines
- If you missed the bareroot planting season, you can still plant
container grown stock and subtropical trees.
- Prune conifers in active growth.
- Prune spring bloomers, like camillias, after bloom
is finished.
- Mulch broadleaf evergreens.
- Pick up camillia blossoms. This will prevent petal blight
next year.
- Shear hedges.
- Water new plants, at least, weekly. If we have a hot spell, you
will need to water more often.
- Fertilize new plants when they begin to grow. I use a
general fertilizer, whatever was on sale, for all of my garden
except for my roses, where I use a systemic, and my acid loving
plants, where I use a acid feeder.
- Layer or take softwood cuttings from established trees,
shrubs, and vines.
Roses
- Fertilize monthly. I prefer to use a systemic fertilizer.
- Mulch.
- Deadhead faded flowers. I cut back to a five-part leaf that is
growing in the direction that I want the rose cane to grow.
Ground Covers
- Fertilize established groundcovers or top-dress with compost.
Perennials
- Plant summer and fall bloomers.
- Plant tropical and subtropical species.
- Pinch back mums.
- Provide stakes for tall plants.
- Feed or top-dress with compost new plants when they start to
grow, and feed or top-dress established plants.
- Mulch.
Bulbs
- Finish planting summer bulbs.
- Feed when shoots appear.
- Divide and transplant spring bulbs, like daffodils, when leaves
turn yellow.
- Feed spring bulbs when they finish blooming.
- Deadhead, but leave foliage.
- Note where you want to plant bulbs next year.
Annuals
- Plant cosmos, impatiens, petunias, and zinnias.
- Start seeds.
- Feed.
- Pull up winter annuals when they look fatigued.
Container Gardens
- Plant summer veggies, tender herbs, and flowers.
- Move tender plants back outdoors.
- Feed.
- Support climbers.
Kitchen Garden: Vegetables and Herbs
- Plant tender veggies like eggplant, lettuce, pepper, and tomato
seedlings, and tender herbs, like basil.
- Harvest early crops.
- Feed.
- Put out stakes and other supports for plants like tomatos.
- Turn compost pile.
Fruit
- Plant tropical fruit.
- Feed fruit trees.
- Stake brambles.
- Thin citrus, apples, and peaches. I like to keep 4-8 inches
between each fruit. If you don't do this, you risk breaking
branches that are heavily laden.
- Cover berries and nuts with netting.
- Prune. You are looking for damaged or weak growth, perhaps from
winter storms, fire
blight and other diseases, and awkward growth. Diseased
branches should not be composted.
