January To-Do’s for the Santa Cruz Mtns

Leave a comment

A new year in the garden. I'm already starting to make journal entries for January. Not much to shout about in the weather department. We've had dry Decembers before but if January turns out to be the start of 6 weeks of Caribbean-like weather like last year we'll never catch up.

The weather affects how things grow as much as the soil that plants grow in. Remember the cool spring and summer we had while you waited for your tomatoes to ripen? I was just looking at the weather forecasts for 2010 that the Farmer's Almanac predicted. Last May when I first wrote about them they were way off for the first half of the year and at best were hit and miss for the latter half. October did bring rain for us as predicted but they hedged their bets for November calling for "bands of showers" off and on during the month. December for us brought lots of frost and a heavy wind storm.  Although the frost was predicted by the Almanac, I didn't see any "light to moderate rainfall" in December. I put my trust in the satellite map, internet weather sites and my own common sense to judge when to start planting, pruning and transplanting for the season.

This year I'm going to start off right by noting on my calendar at the beginning of each month just what I need to do to ensure a happy, healthy garden.

Here are the tasks to do in the garden in January:

  • Plan for spring. Bareroot fruit, nut, berry and ornamental season runs through the end of February. Don't miss this inexpensive way to add to your edible garden or your landscape.
  • Cut back hydrangeas if you haven't already done so. Apply soil sulfur, aluminum sulfate or other acidifier if you want to encourage blue flowers. You must do this before they set flower buds or it won't help.
  • Prune fruit, nut and shade trees and spray with horticultural oil, lime sulfur, liquid sulfur or copper dormant spray. You should get one more spraying in about Valentine's Day. This is actually the most important one as it's just before bud break. Don't use lime-sulfer on apricots, though.
  • Cut back summer flowering deciduous shrubs and vines.  Don't prune spring flowering varieties like lilac, flowering cherry, plum and crabapple, rhododendrons, azaleas, camellias, weigela and spirea until after flowering but you can cut some during flowering to bring in for bouquets.
  • Control overgrown honeysuckle, potato vine, morning glory, trumpet creeper and pink jasmine by thinning now or even cutting back low to the ground if  they are a big tangled mess.
  • Prune roses towards the end of the month. I'll tell you how to do this later but it's not as hard as it sounds.
  • Bait for slugs and snails

And here are the tasks you should not do in January:

  • Don't cut back grasses yet if you get frost in the area where they grow.
  • Wait to prune back perennials that may have their new foliage damaged in a late frost
  • Wait until February to prune frost  damaged shrubs  if you can tell how far down the die back goes otherwise wait until growth starts in the spring.
  • Wait to prune fuchsias and other perennials until February.
  • Don't fertilize houseplants until March. Because they are resting at this time of year, they use little water.  Don't overwater.  Be sure they are dry before watering.

As always, if you have any questions, feel free to email me. I'd love to hear from you.

Art & Landscapes @ the DeYoung & Palace of Fine Arts

Leave a comment

Still thinking of what to give that special someone for Christmas? Recently I spent the day at the De Young Museum enjoying the Renaissance paintings on loan from Venice, Italy. Also got over the The Palace of Fine Arts for the exhibit of the the Impressionist, Passarro.

 The paintings are powerful and inspiring. I was especially drawn to the landscapes. Looking at the pomegranate, olive and apple trees gave me some ideas for holiday presents.

Because Venice was literally built on a forest of tree trunks driven into the mud of a marsh it's geography is unique. In a city built on water, plants were highly valued and nurtured on terraces and courtyards. There was a longing for natural settings and this is clear in the the Renaissance painters work. Mediterranean plants from the mainland were brought over to grace the houses of the wealthy. Laurel trees, signifying purity and chastity, are often depicted in these masterpieces.

What a great gift one of these masterpieces  would make. But what if you don't have millions to buy an original? Here are some other ideas to consider.

The landscapes depicted in many of the paintings inspired me to work on my Christmas list.  I'm a gardener starved for color, life and greenery.  It was 29 degrees in my garden in Felton this morning and I know many of you experienced even colder temps after the brightness of the stars on a clear overnight sky.

Thick frost finished off this year's garden- what was left after the wind storm anyway. Even the more sheltered places look a little winter weary this year. Winter is here a tad early for our California gardens. Make the most of those empty spaces in your garden and those of the fellow gardeners you'd like to remember during the holidays.

Are your containers looking a little sad about now? A little bleak and bare? Then so are everybody else's. Why not go beyond cabbages and pansies and give some inspiration with colorful textural combinations that will last through the darkest days of winter.

Native plants grow well in containers. Sure most are great drought tolerant additions to the garden but have you thought about putting them together in a container for giving to someone on your list? Any of the cool blue succulents in the dudleya family look breathtaking planted in blue glazed container. A manzanita like Dr. Hurd  looks quite dramatic in a large pot. Don't worry about if the plant will outgrow the container eventually. You are essentially planting a giant bonsai and root pruning every few years will keep both of you happy and healthy. Drainage is the most important aspect of planting most natives so be sure to add pumice or lava rock to your planting mix.

What else would make a good gift? There's always a new pair of gardening boots for that special gift but if you're thinking smaller, maybe a dry arrangement from seed heads, pods and foliage from your garden in a thrift shop container would fit the bill. Leaving dried perennials and grasses to overwinter in the garden is a present for our birds who appreciate the banquet. There's no need to tidy up unless they've collapsed in a slimy heap. Take advantage of the excuse to kick back over the holidays and enjoy yourself.
 

California Native Plants, colorful foliage

Fall Color for the Santa Cruz Mountains

Leave a comment

The end of daylight savings time signals to me that autumn is really here in our mild California surroundings. We may not have as many fall color foliage trees and shrubs as other states but we love ours just as much.  Besides we don’t get snow two days before Halloween. Can you imagine? Enjoy these crisp mornings and warm days and to make your garden more compelling, try mixing in trees and shrubs with bold leaves and a wide range of autumn color.

Bright trees and shrubs add color flashes to fall gardens. Sasanqua camellias have already started blooming and will continue to flower throughout the winter. In addition to asters and rudbeckia, Japanese anemones are the stars of the border at this time of year. The electric blue flowers of dwarf plumbago contrast with reddish leaves as night temperatures dip. Summer Snowflake viburnum, Encore azalea, Endless Summer hydrangea and loropetalum are blooming now, too.

But what about vivid foliage in the garden? Which plants put on the best show in our area? Here are some of my favorites.

We are all familiar with the brilliant fall color of Japanese maples. Bloodgood is probably the single most popular upright purple-leaved variety seen in gardens. Beautiful in color and form, it’s easy to grow and fits nicely in the smaller garden.

A great tree for the gardener interested in edibles is the Fuyu persimmon. This beautiful small tree is ornamental with glossy green leaves and also offers a dramatic fall display in shades of yellow, orange and red. Bright orange fruit begins to develop in late October and clings to bare branches usually through December. The tree looks more like it’s covered with holiday ornaments than fruit. And have you priced persimmons in the store lately?

Blueberries are a must for the edible gardener. They can used to make a beautiful hedge that provides showy red or yellow fall color.  Because of our colder winters here in the mountains, we can grow both northern highbush which are self-fertile and southern highbush which produce better with another type to pollinize them. They can be great foundation plants around the home as well as in the garden.

A vine that lights up with the onset of autumn is Rogers Red California grape. If you have an arbor, wall or fence that need covering quickly, this is your plant. The green and gray leaves are transformed in autumn into great draperies of rich, scarlet red leaves with clusters of summer fruit turning all shades of purple.

Japanese barberries are deer resistant, low water-use small shrubs that make them superb hedge plants, background plants against fences and foundations or accent plants. Red or lime colored summer foliage changes to orange, red or amber in the fall. I love the graceful growing habit of many of the varieties but there are pillar forms and also dwarf types.

Bright foliage on trees like red maples, liquidamber, Chinese pistache, ginkgo, ornamental pear, cherry or crabapple, dogwood, goldenrain, locust, katsura, oak, redbud, sumac and witchhazel all add to the fall drama of the landscape.

Light up your garden as the light fades and the days shorten. I know my garden needs a greater variety of fall color than just the Japanese maples in pots on the deck and the barberries. Maybe I’ll add a purple smoke bush with leaves than turn luminous scarlet to add color flashes to my fall garden.
