This past week found us all embracing the rains falling from above. A whopping 14.76 inches of rain fell at Lake Lagunitas. The 41,924 acre-feet of water stored in our lakes before the storm rose to 50,748 acre-feet after. Are we out of the woods regarding the drought? Can we return to our old ways of thinking about how we use water? No. We are in much better shape after the storm, but we can’t let the rain make us complacent. Keep up the great work you are doing. Keep focused on conservation!

It was easy to stay focused on conservation with Brad Lancaster, the guru “water stretcher” extraordinaire, speaking in the Bay Area on Monday night and Tuesday morning. Tuesday morning found the room packed as Brad shared his experiences and findings in such places as Saudi Arabia, Israel, and South Korea. Some of the sites he spoke of lived successfully on as little as four inches of water a year!

Brad spoke about how these countries focused on graywater use as well as capturing and storing rainwater. He talked about using plant materials that were indigenous to the region and about grading to create bioswales so water slows down, spreads out, and sinks into the soil instead of running off. He talked about creating sponges of our soils by letting clippings lay where they fall to allow for natural composting.

His lectures were so detailed it would take several blog posts to cover all the points that he discussed. Therefore, once I get home, I plan to spend several weeks exploring in more detail the topics he covered.

I must admit, being in Marin in February was a double treat. First, the rains seemed to lift everyone’s spirits. Secondly, everywhere I went, Daphne odora was in bloom. The fragrance wafting through the air intercepted me entering the bank on Fourth Street in San Rafael, walking toward the building where Brad spoke, and even visiting my daughter’s home. Daphne is the perfect plant for me. Deer don’t eat it; it thrives in the deepest shade with minimal water; it blooms at the time of year when most other plants lay dormant; and, oh, that fragrance can stop you dead in your tracks! It is a plant that thrives on neglect. Pampering it will leave you disappointed.

Flowering quince

Flowering quince

There is another plant that captured my attention while in Marin. Chaenomeles, otherwise known as flowering quince, is a beautiful plant that is rarely seen in gardens anymore, yet carries many of the same favorable qualities as daphne. Deer don’t bother it; minimal water is needed to keep it looking good; and it comes in beautiful shades of red, orange, pink, coral, or white. The difference in the two plants is flowering quince is much happier in the sun and, while lacking fragrance, it will thrive in temperatures well below zero—a plant after my own heart. It didn’t take long before I was driving to the local nurseries choosing just the right plants to live in Lassen! Of course, while there, I couldn’t leave without picking up bareroot edible crops such as asparagus, seed potatoes, and onion sets.

Water HarvestingA busy week in Marin has come to a close and finds me preparing to go back home with my head filled with new ideas about how to approach rainwater harvesting and graywater use, and a burning desire to get my hands in the soil to plant new-found treasures. I can only hope our heavy rainfall at home provides workable soil that is no longer frozen!

Wishing you all a very Happy Valentine’s Day.

Is it really January? The skies are crystal clear and the breezes are warm and gentle. This beautiful weather is drawing me away from what I should be doing in the garden right now. I should be checking the nurseries stocked with large bare root assortments of roses, fruit trees, perennial vegetables and ornamentals. I should be perusing seed catalogs and planning for the spring vegetable gardens, but the balmy weather is causing me to fawn after plants that would perish in cold wet weather. This false spring is a temptress!

The unusual weather has led several people to wonder if water rationing is on the horizon. In fact, just thinking about “rationing” brought me back to the ‘70s in Marin when we took extreme measures to save our landscaping. I still have unpleasant memories of hauling buckets of laundry water out to my plants. I wonder now if we had worked harder at conserving our water before that drought, could we have saved more plants from their demise?

The good news is that, thanks to last year’s heavy rains, our reservoirs are only a little below their average capacity for this time of year, and there’s still plenty of time for more rain. But the long dry spell is a reminder of how unpredictable our rainfall can be from year to year and hence why conservation is always important. The more we save now, the less chance of needing to ration water in the future. The question is, why wait? Here are some things we can do right now:

First, attend the Laundry to Landscape class this Saturday, January 14, to learn how to divert laundry water to the garden. Every load of wash could mean several gallons of water rerouted to plants, and every gallon diverted is water saved in our reservoirs and for the salmon. My earlier vision of sore biceps in the ‘70s fades as I consider the ease of minor plumbing changes today.

Next, call to schedule a free Green House Call with California Youth Energy Services. They will check for both electrical and water efficiency and even give your home a mini retrofit with water-efficient showerheads, compact fluorescent lamps (CFLs) and more.

While the weather is so wonderful, check the thickness of mulch around plants to slow the evaporation of moisture from the soil. For new plants, choose water-wise varieties that can provide lots of color without guzzling the liquid gold to survive. When planting them, add a healthy amount of organic matter to the native soil for better moisture retention. Do use the precious resource for edible crops and work the soil with lots of composted materials before planting the vegetable garden this spring.

Irrigation systems are another source of waste if not kept in prime condition. Consider if some spray systems could be converted into drip systems now. A good QWEL irrigation landscape contractor could help here. You might consider turning the irrigation system on—especially if your plants are in need of a drink anyway—to note what needs fixing before irrigation season. Walk around each station while it is watering to make sure emitters aren’t plugged or popped off the tubing. Check spray heads to make certain they are directed toward the area you want watered. Invest in a smart controller to take the guess work out of how long the system should run to keep your plants healthy. We didn’t have smart controllers in the ’70s. This is yet another tool to ease the thought of rationing.

How many water saving ideas can you think of? Please share those ideas with everyone who reads the blog. I will post your tips weekly. The beauty of saving now is we still have several months left for potential rain, and meanwhile we are developing some great habits. I am willing to bet those of us who lived through the ‘70s drought are still implementing many water-saving practices we learned back then!

Frost Damage and Pruning

Since I discussed pruning techniques in the past two weeks, it would be prudent for me to warn that this is not the time to prune frost-tender plants such as bougainvillea and citrus. Despite the temperate days, a hard frost could present itself at any time and do some serious damage. Those tender plants would be left unprotected with their top growth missing. This type of plant must wait until late March or April to see a set of pruning shears. More pruning detail for these plants to follow at that time.

Have a great weekend.

Yet-to-be-pruned peach tree

Yet-to-be-pruned peach tree

Last week’s blog discussed the basics of pruning and included some safety rules. Please review the ten rules here if you missed that post before you begin pruning.

Winter fruit tree pruning is important in that a tree left unpruned will eventually fail to produce fruit. This week let’s tackle the basics of pruning fruit trees. I say basics realizing that I am attempting to condense a subject that fills books.

The age of your tree will determine how you approach the job. A young tree needs to develop strength in its branches and trunk to support the weight of the fruit it will carry when the tree is mature. Begin by determining the natural shape of the tree. Some trees such as apples, pears and sweet cherries grow with a central leader. They have one main trunk and develop alternate branches to form an open goblet allowing light to come into to the center of the tree. In contrast, peaches, nectarines, apricots and plums require an open center method of pruning: Choose three to five well-distributed side branches and remove the central leader. They will look more like an upside-down bowl.

For all fruit trees:

  1. Begin pruning your fruit tree by following the basic rules from last week’s list.
  2. The lateral branches need to be spaced out equally throughout the tree.
  3. Remove the weaker of two branches growing on opposite sides of the trunk to achieve alternate spacing of branches.
  4. Peaches and nectarines need about 12 inches of spacing between the branches. Apples and pears will need about 18 inches.
  5. Remove lateral branches that form a tight crotch at the base of the branch.
  6. Determine where you want the bottom branch because branches will remain at that height in maturity. Consider, in future, if you want to walk under the tree and reach for the fruit or have the fruit at a lower elevation for easy picking. At a minimum, keep the lower branches at least three feet from the ground.
  7. Cut at an angle a quarter-of-an-inch above an outside node to prevent new growth from growing to the inside of the tree.

It is important to understand that some trees bear their fruit on old wood, while some bear on new wood. For example, apples, apricots, pears and plums grow woody spurs no more than four inches long. Apples form on those spurs, so it would behoove you to protect that wood from your pruning shears! Pears, apricots and plums will bear fruit on old wood and one-year-old lateral shoots, so don’t be afraid to snip back one-third of this past year’s growth to shape the tree and encourage more wood for next year’s fruit production. Peaches and nectarines grow on new wood, so be careful to prune back no more than one-third of the new branch shoot to maximize fruit production. Please find more details and examples of your specific variety of fruit tree on the internet or in a good pruning book. You will find a wealth of information out there.

The last part of the job involves raking up and removing all wood, dead leaves and debris around the tree to prevent disease. For example, shotgun-hole fungus will continue to transmit to the new leaves if the dead leaves are left on the ground. If last year’s leaves look like someone shot them full of holes, do not compost them!

The big job is done. Pat yourself on the back and start thinking of the wonderful bounty that awaits you!

Last week I mentioned the need to water plants due to severe dry wind conditions. Wind, like intense heat, can be a water robber that saps life-sustaining moisture from plants. Both elements can have the same ill effect: Plants are unable to transpire fast enough, causing the tips and edges of the leaves to dry up. Intense heat can be corrected by proper mulch and irrigating during the wee hours. However, wind must be treated in a different manner.

What can you do if wind is a problem in your garden? First, reflect on various types of wind screens that will protect plants. You can construct fencing or use plant material to achieve this goal. Our gut instinct is to put up a solid fence to protect the area. However, take note if you are attempting to create a wind block. A solid fence acts to wind just as a low-lying wall acts with ocean wave. The wind or wave action rides up on the barrier and slams down on the opposite side, creating more damage than anticipated. Design the fence so the wind has the ability to move through the fence rather than meet a solid board wall. Similarly, if you use plants for screening, plant various types and heights to create multiple layers allowing the wind to be diffused.

Implementing these methods will allow you to experience a gentle breeze rather than gale forces that are hard on plants and make it difficult for you to enjoy your garden!
