It's February and the earth is beginning to warm up. The daylight hours are getting longer. Spring might just be here already!
Spring flowering shrubs are in full bloom all over town (see article left). In the garden Hardenbergia and Winter flowering Jasmine vines are in full bloom, the roses and clematis are beginning to leaf out, the bluebells and daffodils are pushing their green tips through the earth, and violets are blooming.
Azaleas are sending out the first buds of the year from the branch tips so it’s time to feed with a high phosphorus fertilizer from now until they are finished blooming.
February is a month for maintenance and preparation. There is pruning and fertilizing to be done. A lot of what you do this month will reap benefits when the warmer months arrive.
Stay ahead of those weeds!!! We have had a warm winter and everything is growing fast including weeds. If you don’t keep the weeds down now you’ll be sorry!
Finish clearing up old leaves
and debris from under roses and deciduous trees. This debris is a breeding ground for insect lava and fungal diseases and should not be left on the ground.Once you have cleaned it all up, spread a generous layer of mulch to feed the soil and prevent weeds.
Working with nature by using organic products is good for us and good for the plants. Incorporating earthworm castings into your soil is a great first step to going organic. Earthworm castings are a rich, all-natural source of organic matter with lots of nutrients and moisture-holding capabilities. Castings improve the soil structure and increase fertility making them the most enriching soil conditioner available.
This month you will see gardeners de-thatching lawns all over town in preparation for warm-season grass. (FYI – Early fall is de-thatching time for cool-season lawns). Thatch is the layer of matting between the soil below and the blades of grass above. A layer of thatch up to one half inch is okay, but thicker than that is not healthy for a lawn. To keep thatch down to a minimum, don’t mow more than one half of the length of the grass height at one time, and allow the clippings to lay where they fall. The clippings will decompose and will provide a good source of nitrogen to feed your lawn. Feed your lawns, and patch bare spaces with seed amendments, Topper or, if you are old school, Steer Manure.
If you want to transplant or plant shrubs, perennials, grasses, fruit trees, citrus trees, herbs, or roses, February is the month to do it! Get these plants into the ground while the weather is still nice and cool. They will experience very little stress and have time to establish themselves before the heat of summer.
Many succulents and cacti bloom at this time of the year. February is a good time to repot them if they have out grown their pots – just make sure that they have finished blooming.
Plant azaleas and camellias now while they are in bloom, amending the soil with acid planteing mix.
You can still plant winter crops:
lettuces, broccoli, greens, sugar snaps, and cabbage, and you can also still plant cool season annuals such as pansies, cyclamen, primroses, sweet peas and snapdragons.
Tomatoes: We have been so warm that the spring crop of tomaoto plants are here early. We have 8 varieties now with many more to come. It feels so like spring what are we waiting for? Go ahead and start planting!
Get your herb garden started! We have a comprehensive range of new season herbs in 4" pots - all can be planted or potted up now.
Time to start seeds for flowers and vegetables for transplanting in early spring. Seeds to sow outside – ageratums, alyssum, bachelor’s buttons, calendulas, candytuft, celosia, columbines, coreopsis, English daisies, delphiniums, dianthus, forget-me-nots, four-o-clocks, hollyhocks, larkspur, lunaria, pansies, California and Shirley poppies, salvias, snapdragons, stocks, sweet peas, sweet William, and native wildflowers.
Seed Planting Tip: Don’t plant seeds too deeply. Seeds planted too deeply will never reach the soil surface. One of the biggest mistakes made by a beginning gardener is planting too deeply. As a general rule, the soil that covers the seeds should be only three times their thickness. Small seeds, like carrot or lettuce seeds, need only a one-eighth-inch covering of soil at the most.
When annuals such as pansies start to get spindly, pinch back the weakened growth and promptly remove faded flowers. Then feed with a liquid foliage fertilizer. This will make the plants become full and lush again.
We have had very little rainfall this winter and the ground is very dry. Water conservation is vital! However the temperatures are still low and plants and trees do not need as much water as when it is hot. Water your garden in the early morning or in the evening so as to reduce evaporation. If we get some rainfall make sure your irrigation is turned off, but keep an eye on your garden in case we have a hot spell. This is a great time to do irrigation maintenance and repair. Contact our landscape department for all your irrigation needs.
Plumerias have dropped all their leaves with the cold weather. If you want to take cuttings of your plants, this is the time to do it, before the new leaves start to develop. Let the cuttings dry up at the cut end and wait for a week or two before planting.
Pruning winter flowering vines and shrubs like Hardenbergia and some Ceanothus after they bloom gives them a nice clean look, and a head start on next year.
If plants such as liriope and other blade-leaf plants look ragged and unsightly, you can shear them to the ground now before new growth appears and wait for their new leaves to take over.
Cut your cannas and gingers down to the ground now.
Time to give your fuchsias and begonias a hard pruning. Fuchsias bloom only on new wood and need to be cut back annually to produce new growth. Cut back hanging basket plants to container’s edge or 4 inches above the soil. Cut back shrub fuchsias by half or more. Prune begonias to keep them from getting leggy. Cut cane and angel-wing begonias to pot level or three or four nodes from the ground. Prune wax begonias 1-2 inches from the ground.
Buddleias, more commonly known as Butterfly Bushes, need to be hard pruned now. Most plants can’t handle the heavy pruning that these plants can. You can cut back 75% of the plant now and keep pinching the new growth to promote thicker growth over the next few months.
If plants such as agapanthus, coral bells, daylilies, Japanese anemone, Shasta daisies, become crowded or had sparse
bloom last season, it’s time to divide them. Dig up clumps, pull or cut them apart and replant the sections, or share them with your friends. This is easier to do after a good rain or watering the day before.
