Pruning, Thinning and other Early Summer Tasks

Last week the first real taste of summer weather arrived and it was a wake up call for me. Over the past couple of months I?ve planted several new plants that will be drought tolerant once established but for now their root system requires more frequent watering than my established plantings. I?ll have to wait for the cooler weather starting in late September to plant any major additions to my landscaping. But for now I love to be out in my garden and there are lots of other things I can do to enjoy my time outdoors.

Pruning is a good way to spend a couple of hours in your garden. I?m not talking about trimming plants into little balls but the kind of pruning that makes for a healthier and happier plant.

If you grow Japanese maples now is the time to remove dead branches and train your tree to look like one of those specimens you see in the magazines. Thinning cuts build your ideal tree limb structure. If yours is a young tree, though, don?t be tempted to head back long branches too soon. As these mature they give your tree that desirable horizontal branching.

This principle is important to keep in mind when you train any young ornamental tree. Lateral buds grow along the sides of a shoot and give rise to sideways growth that makes a plant bushy.

Summer pruning of fruit trees controls size by removing energy-wasting water sprouts. Summer is also a good time to remove leafy upper branches that excessively shade fruit on the lower branches. Winter pruning is meant to stimulate the tree. Summer pruning uses thinning cuts-where the branch is cut off at its point of attachment, instead of part way along the branch- and these cuts do not encourage new growth but control the size of your tree making fruit harvest easier.

Summer pruning also can control pests like coddling moths, mites or aphids. Just be sure to dispose of these trimmings and don?t compost them.

If you have apricots and cherries, summer pruning only is now advised as they are susceptible to a branch killing disease if pruned during rainy weather. Prune stone fruits like peaches and nectarines after harvest by 50%. They grow quite rapidly. Apricots and plums need to have only 20% of their new growth pruned away.

Be sure to thin the fruit on your trees. That?s another good reason to keep them smaller so you can more easily reach the branches. The best time to do this is when the fruit is still small. Thinning fruit discourages early fruit drop and improves the quality of the remaining fruit. It helps to avoid limb damage from a heavy fruit load. Also it stimulates next year?s crop and helps to avoid biennial bearing. Left to their own devices, a fruit tree may bear heavily one year and then light or not at all the next year. Some types of fruit trees like peaches and Golden Delicious apples are likely to bear biennially if the current year?s fruit crop isn?t thinned.

While I have the pruners out I?ll be shearing back early flowering perennials to encourage another round of blooms. And I?ll add some more mulch to areas that are a little thin. I?ll be checking the ties on my trees to make sure they aren?t too tight and remove the stake if the trunk is strong enough to support the tree on its own.

And I?ll be looking for any pest problems so I can do something about them before it gets out of hand. I?m OK with a few holes here and there but a heavy infestation should be trimmed off or sprayed with an organic insecticide. I inspect the tips of my fuchsias regularly for fuchsia mites and clip off any distorted growth. I hate to spray even organics on them due to the hummingbird activity.

Most importantly, enjoy your time outdoors. If a task is too big to do at one time, break it down into smaller sessions. As they say, take time to smell the roses.

A Little Slice of Heaven in the Santa Cruz Mountains

toolsOutside of the historical agriculture exhibit at the Santa Cruz County Fair I have never seen so many antique farm implements and tools. Vintage tractors and parts were tucked underneath massive black walnuts. The winding driveway was dotted with more equipment, tractor wheels and parts. A storage shed displayed a collection of vintage chain saws and other small tools. California poppies bloomed in small clusters. I was here to visit an old friend in the hills above south Felton near the Toll House resort to see if I could help with advice about his ailing plum trees.

Al HIley has lived in this idyllic location since Vista_from_house.2048he was a boy and that?s a long time as his 92nd birthday is this month. His father bought the 18 acres in 1906. The original house still stands shaded by a grape vine arbor that protects the door and windows in the heat of the day. He lives close by in another house where he enjoys a vista which includes Mt. Umunhum, the Summit and Boulder Creek. Al says he used to be able to see downtown Felton but the redwoods have grown since the late 1800?s when this area was logged.

I had to laugh that Al was asking me for advice. He?s been farming this land starting since WWII ended. His father pAl_Hiley_in orchard2.1600lanted the original walnut trees in the hopes of making a profit from his land but ?he was no farmer?, according to Al. I glanced at the catalogs on the 12? long redwood burl coffee table. You can tell a lot about a person from what they read. Strewn about were several tractor catalogs, Popular Mechanic magazines, Heartland cataantique_chainsaws.1600logs, miscellaneous tool catalogs and a book entitled ?Chainsaws: A History? which touts to be the first book on the worldwide history of the chainsaw.

With his lab, Sonny, at his side, Al and I went out to the orchard to take a look at the fruit trees. Originally in the 1960?s he had about 95 fruit trees. He grafted different kinds of apples onto his father?s trees and planted peaches, and pears as well as plums and prunes. We passed the blueberry bushes which were starting to show some fall color. Nearby grew a fig with a gnarled trunk the likes I have never seen. Loaded with hundreds on hundreds of ripening figs he invited me back to pick some when they ripened.

Al couldn?t verify the exact variety of red apple that caught my eye. It also was? loaded with beautiful fruit. He red_apples.1600got me a bag to pick as many as I wanted to take home and they are crispy and juicy. He grows a yellow delicious apple also but after eating the red variety I didn?t think anything could rival them.

The plum trees weren?t doing as well. They all had some yellow leaves and golden colored sap oozing along the branches. This condition is called gummosis and occurs often in stone fruit trees like cherry, apricot, peach and plum. It can be caused by several very different things.

The tree may have gumming from a pathogen that invades and kills bark and cambial tissue through a wound such as a pruning cut, sun scald or hail. If you scrape the outer bark under the sap the dead phloem will appear cinnamon brown in color Prevention is the key to managing this problem. Keep trees healthy with optimal watering, mulching and nutrition.

gummosis_on_plum.1600Borers can also cause gumming. In a plum tree, weakened trees or places where wounds have occurred will be susceptible. Ooze is often clear. Management of these pests is difficult and may include bark sprays during the growing season.

If you are not sure that a pathogen is causing the gummosis, scrape the outer bark away. If the inner bark is still cream colored and healthy, the oozing is caused by non-living factors and there is nothing you should do. If the wood is tan to brown, it is dead, and was most likely killed by a pathogen.

For my friend, Al?s plum trees I determined that the gummosis was caused by excessive irrigation. Due to the drought, Al had tried to limit watering during the summer. When he saw the trees being stressed he deep watered several times in the past month or so. The apple trees loved it but not the plums. He is happily going to deep water much less often until the trees go dormant.

I left Al and Sonny with the promise that I?d be back when the figs ripened. I?m sure I?ll be needing a fresh supply of apples, too.

Favorite Fruit Varieties at the Farmer’s Market

fruit_from_Farmer's MktAt this time of year it’s easy to get the recommended 9 servings of fruits and vegetables each day. That’s the latest recommendation from the new dietary guidelines released by the Dept. of Agriculture and Health and Human Services. The farmer’s market is brimming now with lots of locally grown produce. I find it nearly impossible not to overbuy, everything looks so yummy. At the beginning of the year I wrote about great varieties of fruit trees available to plant in your home orchard. From heirlooms to old favorites there’s nothing like picking fresh from the tree. Walking around the Felton Farmer’s Market the other day I thought I’d check out what the growers thought were the best kinds and why in their opinion.

Red, ripe strawberries first caught my eye. Jose, told me he grows Seascape Seascape_strawberriesstrawberries in La Selva Beach. His farm is on a well so the dry winter didn’t affect their plants but the recents showers did. The berries absorbed too much water at one time and are not as sweet this week as a result. Esther, a grower from Moss Landing, said she likes the variety Albion at this time of year because they are really sweet and hold up well. Her farm will start harvesting Seascapes later. She said her area didn’t get any showers recently but the March rains caused the berries to rot and the whole crop ready at the time had to be picked and thrown away.

The apricots next got my attention. I love apricots. These beautiful orange colored fruits are full of beta-carotene and fiber and are one of the first signs of summer. I found out from David from a farm in Sanger, California in Fresno County that apricot season only lasts for 7 weeks. His farm grows 6 different kinds including Red Ruby, Castlebright, Patterson, Queen Sweet, Royal Flame and Blenheim. He said his favorites are Royal Flame, Queen Sweet and Blenheim. After tasting some of the the delicious Royal Flame samples I am looking forward to his other favorites.

And then I was in peach and nectarine heaven as I sampled my way through the farmer’s market. David didn’t have to tempt me much with his aromatic samples of Saturn white peaches, which are his favorite. Another booth from a farm in Hickman featured White Lady peaches. Corona said his favorite, the O’Henry freestone, will be ripening soon. I was amazed to learn that this farm grows 100 different varieties of peach and nectarine. His favorite nectarine? Not surprisingly, it’s the Red Top, a yellow fleshed nectarine and the Arctic Rose, the white variety he just happened to have ready with samples available.

Pluots have always been one of my favorite fruits. They are second generation hybrids of plums and apricots although they closely resemble plums. According to UC Cooperative Extension in Sacramento County? pluots are one of the best choices for backyard trees. The flesh is unusually sweet and juicy with complex plum-apricot flavors and the skin in without the bitterness found in the skin of regular plums. I’ll be looking for Dapple Dandy and Flavor Grenade as the season professes.

After taste testing my way through the various booths I came away with way with probably too much fruit and vegetables to eat in one week but I’ll force myself with a huge smile on my face. When I look and smell all the luscious produce I bought maybe those 9 servings per day aren’t so much after all. Just so you know, nine servings translates to about 2 cups of fruit and 2 1/2 cups of vegetables every day.
