There’s much to do in the September garden!
by Terri Sonleitner Law
UC Master Gardener
Q. I’m unsure what gardening activities I should be doing now. Any suggestions? Sam S., Atascadero
A. September’s a great month in the garden and there’s plenty to do. Although some days may be summertime hot, days are shortening, shadows lengthen, and fall colors begin to appear in the landscape with the arrival of the Autumnal Equinox on September 22nd.
- Fall is our best planting season! Select healthy trees and other permanent plants, considering your site, drainage, and soil requirements. Consider selecting and planting California natives and be sure they have enough water until rains begin.
- You can plant fall-blooming perennials, such as asters, chrysanthemums, daylilies, and salvia, which add fall color to the garden and will be in good supply in September.
- Divide and replant spring-blooming perennials, such as bearded iris, that produced few flowers or were smaller than usual. Share the extras with friends and neighbors!
- Mulches decompose in the warm months, so it’s a good time to add more to the garden. It’s also a good time to check your watering system to make sure it’s working properly and not wasting water.
- Fertilize trees, shrubs, groundcovers, roses, and warm-season grasses.
- If your lawn is in bad shape due to drought stress, insects, weeds or other reasons, and you want to spruce it up, September is a great time to do so.
- A light pruning of roses will reward you with another round of lovely blooms once daytime temperatures have moderated.
- There is life after basil! Plant some perennial culinary herbs such as parsley, rosemary, sage, thyme, or winter savory.
- The kitchen garden is a busy place. Continue harvesting summer crops. Many delicious and nutritious cool season vegetables can be planted now from seed or starts: beets, cabbages, carrots, kale, kolhrabi, lettuce, mesclun mixes, mustards, green onions, peas, radishes, spinach, turnips and rutabaga.
- Lastly, don’t forget to take some time to enjoy the warmth and renewal the changing seasons bring to your September garden.

Q. I am interested in growing an avocado tree. What should I be aware of before I plant?
Aedan G.
By Andrea Peck Master Gardener
A. The first step to planting anything is to make sure it is well suited to your specific climate. Your climate zone and microclimate will determine which plants will grow well in your garden. The avocado tree originated in the tropical climates of South America and may not be well suited to some cool coastal climates. If possible, purchase your tree in the spring, after the last chance of frost to give your tree a good head start.
The avocado tree requires delicate treatment during planting. Make sure the hole is as deep as the root ball and twice the diameter. Once planted, the tree ball should rest about one inch above the surrounding ground to prevent excess moisture from reaching the trunk. Irrigate your new tree immediately after planting.
Botanically, the avocado flower is unique. Each flower has a female portion which opens for a few hours on one day. On the second day the flower sheds pollen and is now acting as a male flower. Honey bees transfer pollen from male-stage flowers to female-stage flowers. Pollination activities and fruit set are improved when more than one tree is planted within close proximity.
Pollination is highly dependent on temperature. Temperatures around 70⁰F are ideal for flowering. Colder temperatures, even in the 60⁰F range, significantly lower fruit set while sudden hot spells may cause fruit drop.
The avocado’s smooth, creamy and subtle taste continues to rise in popularity as a culinary treat. The avocado packs a nutritional wallop as well. It is known for its cholesterol-fighting monounsaturated fats and its high vitamin and mineral content.

Worm composting is slow, but it's great for your plants~ It's worth it!
Vermiculture by Jim Borland, Master Gardener
Q – I've heard it's possible to get good compost from worm manure.
Is this true?
Curtis Reinhardt, Shell Beach
A – Yes, you can let worms eat your kitchen scraps and convert it into fertilizer. It's called vermiculture which is a fancy name for worm composting. You need only a few things to get started: a worm bin, newspaper bedding, kitchen scraps and, of course, your little red wigglers.
The worm bin is an aerated container and will be lodging for your worm farm. It may be made from a covered plastic tub, Styrofoam, metal, wood, or you can purchase a commercial worm bin. Your bin will need holes in it for air circulation as well as holes along the bottom to drain excess moisture.
The composting worms most often used are Eisenia foetida, commonly known as red wigglers, and can be purchased at garden centers, bait shops or from suppliers on the Internet. This type of worm has adapted to living in decaying organic material, and they thrive in rotting vegetation.
You can create bedding for your bin with shredded paper such as non-glossy newspaper, office paper or cardboard. Prepare your worm bedding by wetting the paper and wringing it out until it is like a damp sponge. Fluff up the paper and bury some kitchen scraps in the worm bin. Avoid food that contains yeast, onions, meats, oils, citrus or dairy.
The bin may be placed outdoors in a protected place but keeping it indoors works fine in harsh climates. To keep your worms happy you need to think about temperature, moisture, and ventilation. Add fresh kitchen scraps to the bin about twice a week, covering the newly deposited waste with an inch or two of bedding.
Bacteria and fungi exist in the worm bin and help break the food down. The end result will be vermicompost (worm castings), an excellent nutrient-rich food for growing healthy plants. Worm compost is ready to use when it is dark in color and all the vegetation has been digested. You will then harvest your worms and prepare some new bedding for another cycle. Use your vermicompost to fertilize house plants or those in your garden. An for more information, there is a book called "Worms Eat My Garbage" by Mary Appelhoff.

Worm Composting - Composting on a Small Scale
By Lee Oliphant, Ed.D., Master Gardener
Traditional composting is not for everyone. Some folks just don’t have the space for composting bins but would love to have some of the “black gold” plant food that composting provides. If you want to try composting on a smaller, more concentrated level, worm composting (or vermicomposting) might be the answer for providing food for your plants while recycling kitchen scraps and newspaper or shredded office paper. The resultant castings provided by worm composting is a nutrient rich additive to soil. The leachate caught from the box can also be diluted and used to water ornamental plants.
Worm composting requires a shady, cool place for your worms to live. You will need only a few things to begin worm composting: a worm bin, newspaper bedding, kitchen scraps and, of course, your little “Red Wigglers” (Eisenia foetida).
Your Worm Bin
Commercial worm bins are available or you may begin your worm composting you might want to purchase a simple 5 to 10 gallon plastic tub with a lid that snaps shut. Worms like darkness, so an opaque bin is best. Drill 1/4 inch holes around the bin about 4 inches down from the top and 2 to 4 inches apart.
Worms thrive in temperatures between 50 and 75 degrees. Options for bin locations are the garage, basement, a shady deck or area in your garden, or in a garden shed. In the winter, make sure that the box is sheltered from the rain. The worms require oxygen and will easily drown!
Worm Bedding
In their natural habitat, “Red Wigglers” live in piles of fallen leaves above the soil surface. The best bedding in your bin is shredded paper such as uncolored newsprint or cardboard. Prepare your worm bedding by wetting the paper and wringing it or drain it until is like a wrung-out sponge. Separate the damp strips.
Worm Food
A pound of red worms need about a pound of scraps each week. They eat just about any part of fruits and vegetables, coffee grounds and filters, tea bags and watermelon rinds. To begin, layer about a pound of scraps over the bedding. Do not put meat, oils, cat or dog feces, or dairy products, citrus peels or bread that contains yeast in your bin! While worms can survive longer without food, they enjoy a weekly feeding.
The Worm Crew
”Red Wigglers” Eisenia foetida (not to be confused with earthworms) can be purchased at garden centers, bait shops or from suppliers on the Internet. You will need less than a half-pound of worms to begin your worm composting. Worms need to be separated from their casting about twice a year. One method for separation is to push the decomposed material to one side of the bin and remake the worms’ bed with paper and kitchen scraps. Worms will eventually migrate to the freshly filled side of the bin leaving you with fresh compost.
Another method for those of us who can’t wait for the wigglers to meander to “greener” pastures so that castings can be harvested is to expose the open bin to bright light or sunlight. The worms will dive for darker quarters. After a few minutes, remove the top inch (sans worms) and repeat.
Your Payoff
Worm compost is ready to use when all vegetation has been digested. It is very concentrated. You can sprinkle and dig it into freshly cultivated soil or mix one part worm compost to four parts potting mix. .
There are many informational resources for worm composting available. California Department of Resources Recycling and Recovery has an excellent resource page. “Worms Eat My Garbage” by Mary Appelhoff is a book that provides extensive coverage on the subject. Her Web site is wormwoman.com.

Did you find some weird larvae in your worm bin?

Soldier Fly Larvae seems to appear in my worm box throughout the year. Once you recover from their ugliness, you will find that they are excellent composters and the flies are never even seen!
