Warm Spells during the Winter

Leave a comment

Everyone’s talking about the wonderful weather we’ve been enjoying the past few weeks. Spring is in the air. Or is it? Whether you like to putter in the garden or be out hiking, the warblers are calling to you. But is it unusual to have warm weather around here in January? Not at all. Just last year before the rains started we had several weeks of Caribbean-like weather. Back in 2009 during the first two weeks of January temps were in the 70’s and low 80’s. Don’t worry. Mother Nature knows how to adjust to changes in the weather- slowing down when it’s really cold and catching up when it’s mild.

Most plants will acclimate to a gradual return to more normal cooler late winter temperatures. We’re lucky here that we don’t get snow ’cause that’s when nature can really deliver a wallop to tender new growth and buds. If winter remains mild plants may bloom a little earlier. Lilacs, apples and grapes, for example,may flower a week earlier. Weeds can really become aggressive and pests and diseases that were held in check by the cold may become more of a problem. Lifestyles of beneficial insects may get out of sinc with the pests they help control.

Plants make the most of warmer weather. Lawns and other groundcovers, for instance, benefit from warm temperatures in winter. Root growth is encouraged in existing areas and young seedlings  planted last fall become established quicker. If temperatures return to winter norms, grasses will "harden off" and be fine in spring.

Fruit trees usually have no problems with a warm streak. A prolonged warm spell could cause low-chill varieties of peaches, plums and cherries to break bud and flower but these conditions are rare.

It’s a similar story for ornamental trees and shrubs. "Most woody plants have evolved to deal with a brief spell of unseasonably warm weather," says Nina Bassuk, woody plant specialist and director of the Urban Horticulture Institute. Buds won’t open during the first warm spell and then get killed by a return to cold temperatures because buds require a period of cold temperatures to break dormancy. Only some may begin to flower prematurely and risk losing those flowers but the long-term health of most plants probably won’t be affected.

Strawberries are oblivious to the weather. Blackberries and some raspberries are another story. Like some fruit trees, their chilling requirements may have already been met, their buds are swelling and they’re ready to take off. A rapid chill could freeze the buds and canes begin to die from the top down. But even if the entire cane dies, healthy new canes will emerge in spring. The early summer berry crop could be lost but fall berries will be fine.

Most bulbs and perennial flowers should come through a warm spell just fine. The buds of these plants are at or below ground level and often protected further by mulch or leaves. Even if temps return for below freezing, late winter cleanup of old stems will get rid of any winter dieback.

Enjoy this hint of spring. It won’t last for long.

New Year’s Resolutions for Gardeners

Leave a comment

Last year I was brave and published my New Year’s resolutions– at least those that pertain to the garden. It’s now the day of reckoning. Let’s see how I did and which ones I’ll  keep for 2011.   In the garden, as in life, simple changes can make a big difference over a long time. I’m adding a couple new ones that are important, too.

Learn something new every day. Whether it’s something new in the garden or elsewhere, keep learning. I’m starting to learn about local mushrooms. They come up in the most beautiful places. I’m looking forward to the Fungus Fair in January.
Enjoy the simple things. Laugh often. Life is not measured by the breaths we take but by the moments that take our breath away.  Everyday is a gift, that’s why we call it the present.


Of the 16 gardener’s resolutions I made last year I can honestly say I achieved half of them.

I did pay more attention to the size that plants grow and believed the tag when it said "spreading habit". But I also found that pruning shears are life savers  when you just have to have that new foliage plant that just came out.

I started making garden journal entries in February instead of January as I resolved. But then I tried to make up for it in March, May, June, October, November and December.  I missed 5 out of 12 months. I get a "C-".

I added more pollen-producing flowering plants to attract beneficial insects which kept the good guys around longer to eat the bad bugs. And I learned what quite a few of the good guys look like.  ( That counts as two resolutions )

I sat in my garden and enjoyed it, not jumping up to rearrange containers. (This one was easy)

I applied to get my little garden certified as a wildlife habitat  with the National Wildlife Federation by making sure I provided food sources, water, cover, places to raise young and used sustainable gardening techniques.

I fertilized my perennials a couple of times this year with organic compost and fertilizer instead of just once and boy were they happy. The trees and larger shrubs really only need a light dose once a year so I was good there.

I wore sunscreen everyday. (My doctor wants a hat, too. Maybe this year I’ll wear one.)

The other half of last year’s resolutions are being recycled as they’re still good ones:

I will not buy a new flower, shrub or tree until I have a plan for it in the garden.

I will sharpen and clean my garden tools so they look spiffy and work better.

I will start a worm bin with my kitchen scraps and a compost pile for leaves and plant debris. (I have so many raccoons it’s like a party out there at night but I’m going to come up with a critter-proof solution.)

I will weed regularly- not waiting until they’re so tall they swallow up my gardening tools when I lay them down.

I will accept a few holes in my plants but tour the garden regularly to identify if a problem is getting out of control and I need to break out an organic pesticide.

I will prune my maples, transplant my overgrown containers and divide my perennials when I’m supposed to.

I will plant more things to eat. Edibles anywhere in the garden feed the body and the soul. (This summer was so cold I didn’t have much luck in my partial shade.)

I will stop rationalizing my plant habit is better than gambling, clothes shopping or smoking.

I will do better to practice what I preach in this column.

Happy New Year in 2011 from The Mountain Gardener

Bees as Pollinators

Leave a comment

Does spring have you thinking about the birds and the bees? Good. As a gardener you need a variety of insects and other creatures to pollinate your plants.

Most fruits and vegetables, except crops like tomatoes, corn, peppers, eggplant, beans, beets and wheat, need bees to pollinate them. Honeybees are vital for the pollination of the rest of your vegetables and fruits.

Honeybees will pollinate a wide variety of crops throughout the growing season. Unlike other insects that might go from cucumber blossom to dandelion to squash flower when the honeybee leaves a hive in search of food, it will feed on only one type of flower- whichever type it tasted first on that trip. That way, it picks up and deposits only one kind of pollen making honeybees particularly efficient at pollinating crops.

A combination of factors has caused the honeybee population to decline in the last 50 years. Honeybees aren’t native to the U.S. Colonists brought them here in the 1600’s to pollinate the apple trees, provide honey and also wax for candles. For centuries their numbers expanded, but since the late 1950’s they’ve steadily declined. They die more easily when disease parasites strike and they’re less likely to survive a harsh winter.

One threat comes from varroa and tracheal mite, two parasites that can kill honeybees and decimate colonies. Another is colony collapse disorder, a disease that quickly kills off bees in large numbers. Scientists are close to figuring out the cause of the disorder which appears to be linked to a combination of nutritional deficiencies, pesticides, virus and other diseases. Entomologists hope that over time, natural selection will result in stronger bees and less threatening mites.

You can help increase the chances of the bee’s survival and ensure your own bountiful fruit and vegetable crops by planting flowers that they like and add more native plants to your property. Some of the plants that are excellent bee attractors include annuals like cosmos and zinnia that are a favorite of butterflies, too. Calif. poppies and sunflowers are also frequented by bees. Perennial plants they favor are Mexican bush sage, lavender, penstemon, asters, rosemary, Russian sage, coreopsis, gaillardia, echinacea, sedum and erysimum. Native plants that attract both honeybees and native bees include ceanothus, toyon, buckwheat, coyote mint, salvia, ribes and sambucus.

Since pesticides are another deterrent to their survival, look for non toxic ways of controlling garden pests.

Remember that the 1600 species of our native bees are also in decline mainly from habitat loss. They are solely responsible for pollinating many of our native plants. Being solitary they do not make a hive but make nests underground, one female per nesting hole and she lays her eggs there. Be sure to leave some unmulched areas near your flowering plants for her to burrow.

Honeybees and native bees need help to survive and we’re the ones who need to give it. Besides planting nectar and pollen sources you can help by buying local honey which support beekeepers.
