About Our Google Groups
- Offer your extra plants (except citrus) to others within SLO County.
- Request if anyone has a specific type of plant (except citrus) to give away from within SLO County.
Help prevent the spread of pests within our county. Here are the pests and plants that are of concern and links to learn more about them:
- ACP (Asian Citrus Psyllid) Quarantine prohibits moving citrus plants, curry plants.
Unfortunately, ACP findings in SLO County are on the increase. See this May 11, 2018 article in the Citrus Insider: ACP Found in San Luis Obispo County.
- The following pests can be checked for BEFORE trading plants!
Please carefully inspect your plant, remove any pests and only trade clean plants:
- LBAM (Light Brown Apple Moth)
It's not just on apple trees, it has over 250 plant hosts!
Look for rolled leaves and remove them. The leaf rolling larva is hiding inside.
- Apple Maggot
(not the same as Coddling Moth). Remove any apples from tree before trading.
More on the Apple Maggot.
- Indian Walking Stick
(all over the Coastal areas). Look for notched leaves and inspect at night! One female can lay 1000s of tiny brown eggs which blend into soil!
- Bagrada Bugs
like Cole crops (mustards...), sweet alyssum & candytuft.
- Snails and slugs. Check under plants and pot.
- Ants, aphids, whitefly, mealybugs & scale. Ants and black sooty mold are a sign that the plant also has sucking insects.
- IF you want to bring a plant in from another county, please contact the Pest Exclusion Program at San Luis Obispo County Department of Agriculture for requirements and inspection:

Plants in the Central Coast Area
Fruiting plants that grow in the Central Coast area:
our members share their first-hand experiences.
Las Pilitas Nursery, which we thoroughly enjoyed visiting during our May 2018 meeting, has a wealth of information about native plants on their website, including Incredible Edibles and Drought tolerant native plants for a San Luis Obispo area garden.
At our August 11, 2018 meeting Cameron Newell gave us an overview of the
Xerces Society and the work they do.
He discussed the current state of pollinator and other invertebrate population health,
some of the current initiatives they are implementing and how those relate
to the fruit growing and agriculture industries.
Listen to Cameron's talk on YouTube: Part 1 of 3 | Part 2 of 3 | Part 3 of 3
Thank you Tom S. for recording the video.
Cameron is a Pollinator Conservation Specialist and Bee Better Certified Coordinator from Xerces Society's Southwest Regional Office in San Diego. The Xerces Society is an international nonprofit organization that protects wildlife through the conservation of invertebrates and their habitat.

Q & A:
Q. "I am trying to figure out which peach trees to plant in my orchard. I currently have a May pride and an Elberta. I want to add two or three more peach trees but I want to pick varieties that give me the longest harvest. Do you have any suggestions on good low chill varieties that might help with this?"
A. "You are doing the right thing by planning your harvest times early. My first suggestion would be to go to the Dave Wilson site and look at the harvest chart, it shows harvest times for a wide variety of fruit, note the late peaches, then cross reference with their low chill peach list. You could further narrow by seeing if any of the late low chill peaches are also on their top taste test winners list." Larry Hollis
Q. "I live near foothills in El Cajon, CA, suburb of San Diego. Some of my avocado trees do not have much fruit this year. Also, my Hass had a gazillion leaves and avocados, starting to drop all leaves then all fruit then slowly totally died. At that time I also had a Lamb Hass, tons of leaves, fruit, glorious, then we had temps go over 100 degrees, died in 1 day, just died."
A. All avocados are very alternate bearing so if the crop is small the next year the crop is large. That is the way my Hass and Reed have been producing. My greatest producer is Reed and I pick the fruit from August until January once it has been on the tree 17 months. Sharwil, Julia and Hellen need a little over a year on the tree. I am sorry that your trees have had such a tough time in the heat. The heat made many avocado trees drop their crop. Before a very hot day is forecast the best way to keep the trees alive, pretty and the fruit from falling is to water very heavily so the trees can respire the extra water and not dry out.
