In 2013 I declared war against the codling moth. Why? I have two beautiful apple trees and by July 80% to 90% of the apples are riddled with nasty, little worms.
Know Your Enemy: The codling moth life cycle is pretty basic. Moths emerge mid spring, fly into apple, pear, walnut trees. They mate, lay eggs, eggs hatch, worms slink to the fruit, burrow in and make a mess. Fruit falls to the ground, worms burrow underground, pupate and wait for mid-summer to do it all again. Sometimes three times!
Disrupt The Life Cycle: I went to UC Pest Notes for advice. They advise cultural modification first. Best to have nothing growing under the tree, pick up any apples that have fallen from the tree. This helps prevent the worms from going underground and pupating. Next, thin the apples in the tree. When the apples are in clusters leave one apple (painful but it helps). Also, space the apples 4” to 6” apart. Prune some of the suckers or branches in the canopy of the tree. This eliminates any infested apples that are hard to harvest.
I cleaned under my trees, thinned and pruned. What if that's not enough? Again, UC IPM's Pest Notes! Along with some graphic photos, these guide supply you with other ways to disrupt the codling moth life cycle.
Be Relentless: So in 2013 I did it all. I cleaned, thinned, pruned, trapped, calculated and sprayed. Then repeated it again for the next codling moth generations. It was a lot of work!
Harvest time arrived and guess what? IT WORKED! I DID IT! I CRACKED THE CODE! Couldn't wait to spread the word! But, before I went on the road,
I decided to use the 2014 apple season to tighten up my presentation.
The 2014 season was a disaster! Worms in almost every apple.
Persevere: I continued through the seasons using the Pest Note's advice and added a few new steps. One year, with a minimal apple crop, I removed every apple I could reach, thinking no apples for the worms = no food, no pupa, no moths. Didn't work. Another year, I spent the summer in my trees trying to remove every infested apple. HA!
2023. I was nosing around YouTube for some apple inspiration, and I found an apple grower in Australia with a few, new to me, codling moth ideas.
This farmer layers cardboard mulch under the tree. Thinking, if the pupa can't emerge as moths, it might reduce the worm population. And when the moths are flying in the tree (a few hours in the evening for 2 or 3 days) this same smart farmer lightly sprays the tree in hopes of wetting the moth's wings to inhibit their flying and egg laying.
Well, I can do that. So, this year I covered all the steps from previous years and added the cardboard mulch and water spray steps.
The first generation for this year has passed. I see little damage. After the second and possibly third generation come and go, victory? We will see.
Stay tuned.

Following our many atmospheric rivers this wet winter of 2023, and with the advent of warmer days, weeds are now germinating in record numbers — and with record speed. This is the time to get the hoe out!
Hoes have been used for hundreds of years worldwide, but it surprises me that many local gardeners seldom consider using them.
It is so much easier and faster to stand upright and slice through the base and roots of seedling weeds than it is to kneel or bend over in order to pull or dig out the roots of mature weeds once they have grown. They can also be used around plants to loosen the soil surface where it has formed a pan or to break up compacted soil to prepare it for planting.
There are numerous types of hoe available, but my favorites are a hula hoe (also known as a stirrup hoe or scuffle hoe) and a Japanese hand hoe. The hula is a long handled hoe which works on the push and the pull strokes to slice through unwanted plants just below ground level. Some have a fixed blade, but I prefer those that have a jointed blade that moves very slightly. It is important to check that the handle is a length that allows comfortable use to lessen back strain.
I also have a Japanese triangle hand hoe with an asymmetrical blade. It is a beautifully balanced tool, and it is great for reaching hard to get-at spots such as around the base of rocks or posts. With practice one can remove a weed growing right out of the base of a wanted plant using the point of the blade. One can also loosen soil by using the blade flat, or prepare a seed drill by using one of the points.
In order to hoe safely and not destroy desirable plants, one needs to be able to identify which seedlings or shoots are unwanted weeds as opposed a cherished plant.
The seed leaves of both weeds and desired plants differ remarkably from the true leaves, so getting to recognize each is vital. One of the benefits of planting vegetables in traditional rows is that you will immediately be able to identify the seed leaves of carrots for example, and know that any other leaf shape in, or beside the row is obviously a weed. With good observation one soon gains enough knowledge to spot a dandelion or clover start, or a carpet of grass seeds that are germinating. Five minutes with a hoe and they are gone forever.
Spotting weeds in beds of ornamental plants is a little more challenging, especially if you garden naturally and encourage flowers to self sow. I am currently full of curiosity about a patch of bright green seedlings that have appeared in a fairly new flower bed. I have hoed out those that are simply too close to other plants, but have left some until I can identify them. I suspect that they are orange milkweed, a plant that I grew for the first time last year. I should be able to tell what they are as soon as the true leaves appear then, if they are worthy of cultivation, I can transplant them into an ideal spot.
I could plant up a good-sized herbaceous border with the many volunteers of different species that have sprung up in my flower beds — catmint, centrathus, larkspur, poppies and columbine — but of course I can't keep them all so I usually dig up and pot on some of the best ones and share them with friends. The rest get hoed.
Keeping weeds from establishing in my decomposed granite paths takes a few minutes once a week using a hula hoe and is a lot more enjoyable than trying to grasp the base of a weed from the surrounding “sand paper” since I find that wearing gloves prevents me from being able to grasp tiny plants.
Although you won't kill a bed of established dandelions by hoeing it is possible to weaken them with regular hoeing, and at least prevent them from flowering until you have time to tackle the tap root removal using a hand weeder.
Hoeing with a hula hoe works on bare soil, but not on lawns or the tougher rhizomes of Bermudagrass or on very stony soil or gravel paths but in the right situation it is a gem of a tool!

As the snow melts and waters recede from our recent series of storms most gardeners are looking at a rather sorry landscape with browned plants, torn tree limbs, collapsed shrub branches, and sodden perennials. One itches to tidy everything up and restore order, but how does one tackle such a large task?
Firstly, do an inventory of damage, taking photographs of any major damage, and then make a list of priorities.
Many trees that were originally planted in tract housing frontages in the 1960's are now 60 years old and have suffered abuse from improper pruning and neglect. In the area where I live, mulberries and ash trees were planted extensively, and repeated topping has caused many of them to produce poorly attached limbs which failed with the weight of snow. In one short road 5 mulberry trees and a cedar lost large branches!
Tree safety is of major importance, so look up and note any torn limbs that might pose danger to the public or yourself. If they are large, out of reach, dangling, or hanging over the highway, a roof, or path their removal is a job for a certified arborist. Often these are in short supply after a storm, so move vehicles away and cordon off the area using warning tape or cones until you can get professional help.
Smaller limbs can be cut back to the main trunk of the tree or to a strong lateral branch replacing the tear with a neat saw cut.
Shrubs and bushes were beaten down by the weight of snow, and if this was not removed hastily the branches will often remain bowed. Some plants seem to have the ability to right themselves but many will need staking or tying back to a strong stem. I have a large euonymus which fell apart with the first snow, the branches lying on the ground, but bit by bit it regained its previous form and the remaining holes in the canopy can be closed with some judicious tying-in support.
Upright plants like nandinas or mahonias may need staking, or else removal of damaged stems at ground level to enable healthy new stems to grow during the summer.
Do not be in a hurry to prune frost damaged plants such as figs, ornamental sages, and roses, but wait until the full extent of the damage becomes apparent after new growth begins in the warmer weather and then choose a strong shoot to prune back to.
Many low growing perennial plants with basal leaves that have died or become a soggy mess, such as strawberries should be cleaned up. Removing dead and decaying leaves and other matter from the crowns, leaving only healthy growth lessens the risk of fungal damage and rot setting in. However with some plants it may be necessary to add protection in the event of a late frost.
Waterlogged soils can easily become very compacted if walked on or driven over by machines, so it is far better to keep off the garden altogether until the soil has had time to dry out.
The sun will shine again! Crocuses began blooming as soon as the snow melted and daffodils are full of promise so we have the potential for a wonderful growing year if we give our poor battered plants a little help.

A summer garden in the hot Owens Valley can produce oodles of Tomatoes, Eggplant, Peppers, Zucchini, Garlic, and Onions. Ratatouille is a classic French Provençal stew made from these exact fresh vegetables. Over the years I've tried making every recipe of Ratatouille I could find and while some were better than others none was as good as the Ratatouille from Provence where it had its origin. On a trip to Provence last month, I made it my mission to find out how it is made there and why it is so much better than any I've made here.
Several helpful hints I found:
- Use equal quantities (by weight) of Tomatoes, Eggplant, Peppers, and Zucchini
- Cut all the above vegetables in ½” cubes
- Mise en Place: Cut ALL vegetables before you begin to cook. This will keep everything cooking at the correct amount of time without the worry of the phone ringing or other interruptions.
- There is a certain order that the vegetables are added to the pot. Follow this order. After the addition of each vegetable, cook for 15 minutes before adding the next vegetable.
Best of All: Ratatouille can be frozen. You must let it cool all the way before freezing it. It should be thawed in the refrigerator. I tried this and it works!
Ratatouille de Provence
The recipe:
- Extra Virgin Olive Oil
- Chopped Onion –1-2 large
- Minced Garlic – About 1-2 Tbs
- Tomato Paste – ½ Small Can
- Fresh Basil chopped
Use 1½ pounds of each of the following. Cube everything the same size. About 1/2 inch. For smaller or larger batches, select fairly equal quantities (by weight) of the following.
- Sweet Peppers
- Eggplant
- Zucchini
- Tomato (cored and seeded, but leave skin on)
Cook the following slowly at a Medium Low heat.
- Sauté Onion in extra virgin olive oil until soft. Add Garlic at the end just before Step 2.
- Add Peppers to Onion and cook 15 minutes, stirring as necessary.
- Add Eggplant and cook 15 minutes, stirring as necessary. Add more oil if needed.
- Add Zucchini and cook 15 minutes, stirring as necessary.
- Add Tomato, Tomato Paste, and Basil. Stir to combine. It will seem like there is not enough liquid. There is! Cook slowly to release liquid.
- Continue cooking until done and you have a desirable consistency. Vegetables will still be distinguishable and have some texture.
- Taste for salt and pepper.
Let cool. Serve at lukewarm, room temperature, or cool.
Refrigerate for 3 days or freeze.
Freezing: It is recommended that you freeze in usable quantities. Ratatouille must completely cool before freezing. Pint-size freezer jars are great for this. Leave one-inch head space. Be sure to label with product name and date.
If frozen, let thaw slowly in the refrigerator.

Every year I try to plant something I haven't grown before. I skipped raising vegetables this year, but I planted some red abutilons that I bought on a whim so that I would still feel a little bit like a gardener in spite of taking the year off.
The variety I purchased was a patented hybrid called Lucky Lantern Red®. Botanists and lawyers would call these Abutilon x hybrida ‘Nuabred' PP25443, but that name won't sell plants! Abutilons have several common names but “flowering maple” is often used in California. Since most of these common names are just as many syllables as the botanical name I don't tend to use any of them. Abutilons are in the same family as mallow, hibiscus, cotton, and okra. (Malvaceae)
Abutilons were once popular with plant collectors, but less so now. When I was young I usually encountered them as houseplants. I thought they were cool because they often had a virus that causes them to have intriguing, variegated leaf patterns, only I didn't know that was really just a disease symptom. It turns out mosaic viruses are not really a topic covered in middle-school science class.
Maybe this interesting plant is gaining in popularity again. After all, I found it in Bishop of all places! Several recent varieties are on the market that make for colorful additions to landscapes, with bigger and brighter flowers than older types.
We can grow abutilon in our area, but this being the Eastern Sierra, growing it comes with some caveats. For one thing, you can mostly ignore its label. Plant it green-side-up and keep it watered and you'll be fine. Pinching the tips will encourage more branching.
Many members of this family love the heat. Abutilons tend to like it cooler. Bright sun is great, but mine look stressed when the temperature gets above 90°F in the sun. Here's a good rule: abutilons like the same conditions that make tomatoes happiest.
In May, I planted 4 of them. My two plants that get some mild shade in late afternoon are about 2 feet tall and have a somewhat bushy form. They are about the same size as my miniature roses. The one on my shaded porch is OK and looks better than I expected. The plant in full sun all day that gets very hot: not so much. It's about 12” tall and looks a lot like Bill the Cat. All the plants, no matter where they are planted, are covered with pendulous, red flowers about 2-1/2 inches in diameter.
Although whiteflies are not uncommon on abutilons, I haven't seen too many pests on my plants this season, except for the one planted in full shade which has a few, but not enough to fret about. According to the label they are supposed to be pollinator friendly. I haven't seen any insect activity around the flowers, but hummingbirds have been checking them out all summer.
Beside looking a little wilted in the heat of the afternoon, they have mostly been free of problems. The only problem I have seen on all plants is some mild magnesium deficiency.
I'd give abutilon in Owens Valley a passing grade as an annual, but there are better choices if you desire more visual impact.
Don't count on abutilons becoming a permanent fixture in your landscape, but if you're looking for something out-of-the-ordinary that never stops flowering, it may be a good choice as a summer annual in our area if it gets a break from the heat in the afternoons.

* 'Lucky Lantern' is supposed to be hardy to Zone 8. That means in a mild winter it may survive in Lone Pine or points south. Maybe.
