October garden dates/ GFE classes/ all about aphids from Emily

Upcoming dates in the garden:

Fall Plot Checks
October 15- Baker Beach and South Baker Beach gardens
October 16- Ft. Scott, Portola, West Washington, MacArthur, and Lendrum Court gardens

I'll be looking for vegetables that are flowering/seeding or overgrown and/or excessive weeds or weeds making seeds. If your garden needs a clean up or re-fresh, you have two weekends between now and the plot checks to pay it a visit. And there is even a garden resource day before plot checks!

October Garden Resource Day at the Ft. Scott Community Garden
Saturday October 13, 10am-1pm
We will have compost in buckets you can borrow and a few seedlings to give away. There is also a pile of mulch if you want to spread woodchips around your garden plot.

The pumpkins are still ripening, so we'll plan to have the Fall Pizza Potluck and Pumpkin Party in November. Stay tuned for an Eventbrite RSVP.

The intern corner:

This week, in the garden, our greenhouse seedlings became invested with aphids, so Jean and I ended up having to give most of our plants a bath to remove them. In addition to our plants in the greenhouse, I’ve recently been encountering a lot of plants established in the gardens being infested as well.
            Aphids are small, teardrop-shaped, sucking insects that are most commonly grey or light green and are frequently found on the undersides of leaves. Aphids insert their piercing mouthparts to feed on plant sap. This may eventually cause the plant leaves to wilt and turn yellow. Once they have fed on the plant sap, they excrete a sugary liquid called “honeydew”. Ants love honeydew, so if you spot a plant invested with aphids you’ll probably begin to witness an increase in the presence of ants. The problem with ants is that they protect aphids from their natural predators. Ants and aphids form a mutualistic relationship where the ants literally start to farm the aphid for their honeydew. A fungus called sooty mold can grow on honeydew deposits that accumulate on leaves, turning them black. Aphid numbers can build until conditions are so crowded, or the plant is so stressed, that winged forms are produced. These winged forms fly off in search of new hosts and the process is repeated.

            Early detection is essential when trying to control aphids in your garden plots. When you’re watering, take a few minutes to check your plants, especially the undersides of the leaves. If you happen to have an infestation on your plants there are a couple of steps you can take to help remediate the problem. You can remove the leaves that have a heavy infestation, wash the aphids off with a very strong spray from a garden hose, or use a soap spray that’s approved for use in organic gardens. Remember, aphids tend to attack young or weak plants so maintaining good gardening practices such as watering and fertilizing will help protect your plants, or, if infested, will help to reduce stress by these insects.
