The First Tri-Mester Planting Season
JANUARY
While other parts of the country are firmly entrenched in winter, the acacia trees, pansies, camellias, succulents, and other blooming plants are saying, "Spring!" to us. Take note of the plants that look lovely this time of year if your garden needs a January boost.
Think About Deciduous Fruit Trees. You can prune anytime this month, if it's not raining. If you have rain on that Saturday you set aside, consider it an opportunity to inspect and sharpen your pruning tools.
Spraying Savvy. Organic dormant sprays are now widely available, if you choose to treat your trees. Spray after pruning and before your trees bud out. Spray when there is no rain expected to get the maximum benefit.
Save Space for Perennial Veggies. Make way for strawberries, artichoke, asparagus, and horseradish. All of these vegetables will produce year after year with little care and can be an attractive part of the landscape.
Flower Power. Camellias and azaleas look great this time of year and add lots of color to the garden. It is a good time to buy camellias because, unlike most plants, they like to be transplanted when they are in bloom.
Tree Shopping. Now is a good time to shop for deciduous trees. Without their leaves, it is easy to see the structure of the tree; improper pruning when the tree is still in the can at the nursery may be impossible to correct later. Shop at a nursery that has a good selection of the tree you want and talk to the nursery staff about the best structure for that particular tree.
Perennial Pleasures. There are many attractive perennials that can go in the ground now: centaurea ("Dusty Miller"), many species of daisies, digitalis ("foxglove"), penstemon, achillea ("yarrow"), and agapanthus ("lily of the Nile").
What Not to Plant. Right now, avoid tomatoes and other warm season vegetables and warm season grasses, such as bermuda. You should also resist any bulbs that are soft, very light for their size, or already growing.
FEBRUARY
The days are getting longer this month and rain should be expected. Watering won't be a chore if Mother Nature helps out. No need to irrigate if the temperatures are seasonable (the average high temperature at the coast is 65 degrees, 68 degrees inland) and it rains every 7 - 10 days. February is still a month of dormancy, but spring surely feels like it is upon us.
Radiant Roses. You can still successfully plant bare root roses. By mid-month, you should begin irrigating all of your roses, if there is no rain. Water and mulch deeply to get your roses off to a good start.
Thin Out Old Canes on Climbing Roses. Any sort of pruning can be a dangerous activity, but add thorns, and you really need to be careful. Take time to begin with eye-protection, gloves, substantial shoes, and long sleeves and pants; take time when you finish to mulch your roses.
Plant California Poppies. But before you do, make sure that rain is expected. Rake an area of bare soil, broadcast the seed, and hope for rain. The poppies are eye-popping in bloom, and can reseed from year to year.
Don't Fertilize Natives. Though most plants will be ready for fertilizer sometime this month, natives are the exception. Don't fertilize natives or other Mediterranean-climate plants, but keep planting them as long as the cool weather continues.
Cool Camellias. You've probably noticed camellias blooming over the last month or so. The red, white, and pink blossoms brighten up the winter months and do well in pots or in the ground. Unlike most plants, camellias are best transplanted when blooming, so now is a good time to plant one in a shady spot.
Evergreen Transplanting. Evergreens transplant well now, while the weather is still cool and the soil is damp from rain.
Lose the Legs. Cut back leggy fuchsias and begonias in the ground by one-half or more. Fuchsias and begonias in pots should be cut back so that there is only a few inches of stem. Feed lightly and see how bushy and beautiful your plants become.
Feed Citrus and Avocado. Make sure the soil around the tree trunk is bare to the root line. Allowing a lawn to grow up to the trunk of your ornamental citrus or underplanting with flowers may result in the equivalent of strangulation.
Veggie Delights. It's still too early for heat lovers such as tomatoes to be set out — even if you find them in nurseries. Look for beet, broccoli, dandelion (and most other leafy greens), cauliflower, onion, radish, and carrot.
MARCH
Iris, azaleas, ranunculus, and many types of wild flowers are in bloom as spring takes hold. Water needs will increase with warmer weather and longer day length. It is likely that we will still get some significant rainfall this month, so check before you water, and don't water if the top few inches are wet. Extra time spent mulching now will insulate your plants from unseasonable temperatures, whether hot or cold.
Veggie Delight. Beet, carrot, leafy greens, radish, and turnip are cool-season plants that are almost guaranteed to do well if you plant them at the beginning of the month. By mid-month it may be too late to plant these crops from seed.
Feeling Hot, Hot, Hot. These heat lovers may languish if you put them in now: basil, beans, corn, eggplant, tomato, squash, and melon. Warm-season plants can be put in the ground as soon as temperatures rise; by next month they are a sure bet.
Still Time For Roses. It's not too late to plant bare root roses, if you can find them. You are more likely to find bushes bursting with new growth, at a slightly higher price. Roses are hardy plants for the most part and a little drought won't bother an established plant. However, for best bloom and pest-resistance, water deeply at least once a week, twice if your soil is sandy.
Watch For Aphids. These small sucking insects that are the same color as the plant they are damaging. Aphids can be effectively controlled with a strong blast of water from the hose. Ladybug beetles are the aphid's predator; it's a good sign when you see them in the garden.
Bedding Buddies. Many beautiful bedding plants can be found in the nursery now: marigolds, ageratum, lobelia, petunia, and flax. When you purchase annuals at the nursery, look for small plants that are not in flower. Chances are the small plants are not too root bound and will establish and grow more rapidly. Small plants are also less expensive.
Landscaping Ideas. Assess damage from winter storms now that the weather has turned mild. If rain eroded a slope, consider planting a mix of annuals, perennials, bushes, and trees. California native plants do a great job of holding soil and they attract wildlife. Lemonade berry, scrub oak, matilija poppy, yarrow, California lilac, and buckwheat are all good choices. Non-natives that will do the job well include rockrose, rosemary, and acacia.
Lovely Lawns. Lawns usually look great this time of year — both warm and cool season grasses are growing. This is a good time to start a lawn from either sod or seed, but be vigilant about watering until your turf is established.
APRIL
April is the month when gardens are likely to be at their colorful best. Innumerable bedding plants, perennials, and landscaping plants are flowering now, and they may inspire you to plant during this spring planting season. Despite all of the full-grown plants you see at the nursery, don't ignore the seed rack. April's warm days will help you sprout seeds quickly and there's still a chance of rain.
Consider Azaleas. You can see many beautiful plants in bloom now, and like the camellias you saw in January and February, azaleas are dormant when they bloom. Now is a good time to transplant azaleas; after blooming they will develop new growth.
Wonderful Wisteria. These showy, fragrant vines are appealing throughout the year and are drought-tolerant once established. If you plant wisteria, be sure to put a sturdy support in place before the plant goes in the ground. Wisteria can get very big — and very heavy — in short order.
Poinsettia Power. If you have poinsettias in the ground, you should prune them down to two or three dormant buds this month or next. Look for the old wood on the stem and prune back to two joints above that wood. Abutilon and hibiscus are two other tropical shrubs that may be heavily pruned now to shape and renew them.
Orchard Opulence. Almond, apple, apricot, fig, grape, kiwi, jujube, nectarine, persimmon, plum, and pomegranate may all be successfully planted now. Carefully consider the growing habit and eventual height of the tree when choosing a site.
Search Tree Bases For Suckers. Use the edge of a sharp spade to knock off these bright green sprouts. If you do not remove them, they will weaken the tree and distort its shape.
Valuable Veggies. Beans, carrots, cantaloupes, corn, cucumbers, lettuce, summer squash, tomatoes and watermelon may be planted this month. Coastal and inland lows hovering around 50 degrees, and highs reliably around 70, account for the mix of both summer and winter vegetables. Consider what space you have and add sets or seeds of vegetables.
Buy Winter Annuals. Purchase snapdragons, primrose, stock, and the like only to quickly — and briefly — fill in a space in the border. The warm weather means these lovelies will bolt and set seed soon. Better to wait until next fall to plant them.
Time for Annual Planting. For the heavily irrigated border, try petunia, bedding begonia, coleus, impatiens, and asters. Less water is required for marigolds, sweet alyssum, portulaca, cosmos, and gloriosa daisy.
Natural Natives. Some natives are still blooming in gardens and undisturbed areas. This is a good time to visit parks and demonstration gardens to see native plants. If you have native plants that have bloomed, you can collect the seed now and keep it in a cool, dry place until next rainy season.
