Drought Tolerant Gardening

Leave a comment

arctostaphylos.1280Last fall I wrote about the predictions for winter rains in our area. The Farmer’s Almanac predicted our “winter will be much rainier and cooler than normal”. Weather bloggers online posted an impressive number of charts and figures predicting “a general dry trend”. NOAA said we had an equal chance of precipitation totals going either way.

Even my favorite predictor, the Sandhill crane, who started it’s annual migration to the San Joaquin Valley several weeks earlier this year, seems to have gotten it wrong. The timing of their migration has been a good predictor of both wet and dry winters. This year the early migration predicted an early winter with plenty of rain and snow.

Every snowboarder, gardener and nature lover knows we are in a great drought that started last winter. Information about the California drought is all over the news. We are sure to get a few storms in the coming months but there will be no “Miracle March” from what I see and hear from the experts at NOAA and NASA. This extreme weather event will bring voluntary or possibly mandatory water rationing. What can we do to make the most of the water allotted to the garden and not let expensive mature landscaping die unnecessarily? How can you make your garden more drought tolerant?

1) Group plants in your garden according to their water needs. Some can survive on rainfall bush_poppy.1600alone after their second or third season while the perennial beds, vegetable garden and fruit trees will require a different schedule. Late winter or early spring is a good time to transplant those plants that use more or less water than their neighbors.

2) Examine your irrigation system and watering plan for efficiency and minimal waste. Watering in the early morning is the most efficient way to maximize absorption whether you water by drip system, sprinkler, soaker hose or by hand. The water soaks deep in the soil without risk of evaporation. It bolsters the plant for the day and has dried from leaves by evening reducing the risk for foliar diseases like mildew. Plant roots are also more receptive to watering in the morning. Water slowly, deeply and infrequently so there is no runoff. This also allows plants to grow deep roots that can go longer between waterings.

Mulches are a good choice for areas with less than 33% slope, Vegetation works well on areas with less than a 50% slope. Mulch can be organic-such bark chips, straw or grass clippings or inorganic gravel or cobbles. All protect soil from erosion and conserve soil moisture. Organic mulches keep plant roots cool, encourage earthworms and other beneficial organisms and prevent weed growth. Your plan should be to slow, spread and sink water back into the ground whether it be from rainfall or irrigation.

Of all the types of mulches, recent studies have shown that ramial bark chips are one of the best mulches to improve soil health. Ramial chips are those from trees and brush, from branches up to about 4″ in diameter with or without leaves. Deciduous hardwood is best but all chips are good These chips contain a high percentage of thin young bark and young wood. This is what makes them so valuable to the garden. Young wood is the trees factory for producing protein, glucose, fructose, lignin and polysaccharides. It’s an important source of nutrients for living things at all levels according to a study by 2 soil scientists, G.? Lemieux and R.A. Lapointe.? You can obtain these kind of chips free from tree trimming companies like Davey Tree who is probably working nearby chipping roadside brush for PG&E.

Water makes up 90-98% of every plant we grow. It’s needed for photosynthesis, as well as reproduction and defense against pests. Improving your soil’s ability to absorb and hold water should be a priority when you’re out in the garden. Help ensure the health or your trees and garden by following these steps.

2014 Gardener’s New Year Resolutions

Leave a comment

OLYMPUS DIGITAL CAMERAI plan to turn over a new leaf in 2014. I’m talking about gardening. The rest of my New Year’s resolutions are too numerous to list here!? I wish I could tell you that I’ll never put in another plant that might freeze during the winter. I wish I could tell you that I’ll really start that compost pile this year and duke it out with the raccoons. I wish I could tell you I’ll make more garden journal entries and not rely on sketchy memories. But the reality is gardening shouldn’t be so much about regrets. It’s about the delight we get from coaxing plants from the earth. A garden reflects our lives- always room for growth as well as reflection.

We gardeners are eternal optimists. Why else would we plant a tree or a seed or a garden? I have viola_Etaingrown wiser as the years go by and although a few things froze this month, most will grow back come spring. Some might require a little more patience than others but by April or May most will be looking great. If there are some new transplants, for instance, that suffered because they didn’t have time to establish a strong root system before the deep freeze, I’ll look at it at an opportunity to fill that space with something even better.

I was able to visit some very unique gardens this year and see beneficial insects and beneficial plants at work. When I design a garden I now include even more pollen producing flowering plants to attract beneficials.? This way I keep the good guys around longer to deal with the bad bugs and aid in pollination. Knowing what the good insects look like is important in helping me identify a problem that may be getting out of control.

I’ve kept a garden journal since 1994. In the spirit of full disclosure, some years I do pretty good with it. I add photos and seed packets and lots of info about the weather and how everything did. Other years I’m more hit and miss with my entries. But without the journal most of what happened would be forgotten if not for these scribbled notes. Reading them over returns me to the quiet pleasures of mornings in the garden, of first bloom and the wonder of a hummingbird hovering at eye level.

This year record what does well in your garden.? Were the fruit trees loaded with fruit as you’d hoped?? How many times did you fertilize them?? Did they flower well??? How many bees did you see pollinating them?? Should you add more plants to attract them?? Insect or disease problems??? Room for more?? What kinds would extend your harvest season?

Make notes of what other edibles you want to include in the garden this year.? Bare root season starts in January making it easy to plant grapes, blackberries, strawberries, raspberries, blueberries, artichokes and asparagus.

Make notes about how productive the tomatoes and other veggies did this year. Did you add enough compost to the beds to really feed the soil and the microorganisms?? Did you rotate your crops to prevent a build up of insect and fungal problems?

Think about how the perennials in your garden fared last year – the successes and not so great results.? Make a note if there are any higher water usage plants among the drought tolerant ones.? Come March, move them to a spot you’ve allocated a bit more water.

I wish I could tell you that I would die happy if I could grow a dry farmed Early Girl tomato next year that tastes like summer. That’s my fondest wish for 2014. Doesn’t sound impossible, does it? Enjoy your garden. Set realistic goals. After all, who cares if there are a few weeds here and there when you’re sitting under a shade tree with an ice tea next July. Enjoy a beverage of some kind often in your garden. That clean up or transplanting will be there tomorrow.

Happy New Year from The Mountain Gardener.

Caring for Ornamental Grasses

Leave a comment

rolling_hillsI’ve lived in California my entire life and have traveled on many a back road enjoying the scenery, the trees, the flowers, the birds. Discovering a new road, the road less traveled, is half the fun of any journey. It was close to sunset recently when I found myself on one of those roads. Actually I kinda got lost on my way to Aunt Rosemary’s house and ended up on the back side of Mt. Diablo. Serendipity, the occurrence of events by chance in a happy or beneficial way, was on my side.

With the winter sun skimming the tops of the rolling hills and a meadowlark announcing his presence in the row of walnut trees growing along the road I was reminded of the seasons here in the mild winter areas of California. The setting sun filtered through the grasses tawny in late fall. These grasses are just one of the many ornamental grasses that grace our gardens. With winter coming on, some go dormant, some are evergreen and some are deciduous. How should you take care of the grasses in your garden?

If your grass is big like a miscanthus and now sports that beautiful wheat color as it goes dormant, you can enjoy the show to provide structure to the winter garden as well as seed and cover for wildlife. Come February or early March, before new growth starts from the base, tie the stems into a bundle with twine or a bungee cord and prune down to 10 inches using sharp hedge shears or electric hedge pruning shears.

But what about those other grasses and grass-like plants? How do you keep them neat looking and fresh throughout the year?

If it’s small and goes dormant, like Japanese forest grass, Japanese blood grass or Fountain grass, you hakonechloa_winter.1600can prune them anytime now until early spring. I like to leave them to provide winter interest through the holidays but there will come a day in January when the winter storms will start blowing the leaves everywhere. Then I’ll prune the stems down to 3″ for the shorter grasses or 6″ for the taller fountain grasses. If I prune too low there’s a danger of cutting into the crown of the plant. Moisture then tends to settle into the crown and can rot them out.

Then there are the spiky grasslike plants like New Zealand flax or Cordyline that stay evergreen but can look ratty after a long, hot summer or cold winter. Prune these anytime for cleanup or size reduction, midspring for rejuvenation.

Select the oldest or most damaged leaves and cut them from the base out one by one. To control size, cut out ton more than 2/3 of he tallest leaves at the base. If your plant has severe damage and needs total rejuvenation wait until midspring and cut down to 1 foot. It will regrow in about 4 months but may need retrimming as the leaves grow out.

Like the flaxes, clean up can be done anytime but pruning for rejuvenation should be done early to midspring.

If your grass is looking a bit disheveled, comb out the old stems. Rubber gloves work great for this as the spent foliage clings to the rubber and comes out easily. If you need to go for the big chop to bring it back to its former glory, wait until early spring and cut back by 2/3. Cutting back too much will allow moisture to gather in the crown and cause rot. Rejuvenation pruning shouldn’t be done more than every 2-3 years as small evergreen grasses have less vigor than grasses that go dormant. Mexican feather grass is the exception and can be pruned back hard anytime its needed.

So that’s all there is too it. Decide if your grass is large and goes dormant, small and goes dormant or large and stays evergreen and take it from there for beautiful ornamental grasses year round.
