Moreau Community Garden Gardeners

Your help is needed.

While in the garden this morning I notice that we need to spread the wood chips over the cardboard by the squash mounds near the picnic tables, the mounds need to be weeded, too. Anyone who can give a hand, it will be appreciated.

Also, when you weed your plots, do not leave the debris in the pathways. There is a bin for plant material. Pathways should be just wood chips. Thank you.

Cucumber Beetles Spotted

Striped cucumber beetle adults have arrived in our garden plots. If you are growing squash, cucumber, zucchini or other cucurbit you should be looking for eggs under the leaves closest to the soil.

The eggs are oval and yellow to amber-colored. If you find eggs, remove and destroy them.

The beetles – which are yellow with black stripes – are currently feeding on leaves. Soon, if not already, female beetles will lay eggs. Once the eggs hatch the larvae will feed on the roots and pupate in the soil. Come August, the cycle will be complete and what are now eggs will be adults.

What Damage Do They Do?

They eat leaves and roots. Mature cucurbits can handle some damage. If beetle numbers are high the damage can mean reduced yields. A secondary problem with cucumber beetles is that they are vectors to a disease known as bacterial wilt. If you notice leaves turning a dark green, wilting and then dying, this is a symptom of bacterial wilt. Some plants – such as pumpkins – are more susceptible than others to this disease.

How Do I Know if My Plants have Bacterial Wilt?

Cut a section on the stem. Hold the stem together and then slowly pull it apart. If bacterial wilt is present the sap will appear string-like between the cut ends.

How to Control and When

Striped cucumber beetles are most active evenings and through the night. Since it is most effective to spray the beetle directly this would be the ideal time to apply a spray of Neem Oil. If you find beetles on your squash apply neem oil in the next two weeks. In addition to aiming at the beetle, be certain to spray under the leaves at the base of the plant where eggs and larvae are likely to be located.

A labelled spray bottle of Neem Oil will be placed in the shed in the next few days for everyone to use.

Never, Never, Never spray in the heat of the day. This can kill a plant. Wait until evening and aim for contact with the beetle.

Squash Bugs . . . Yikes

I don’t know when I’ve seen so many squash bugs in a garden then what we are experiencing at the Moreau Community Garden.

Last Thursday I pulled between 20 and 30 out of one plot. And I didn’t get them all because there were some that saw me coming and flew off.

This is bad news for the zucchini, squash, pumpkins, cucumbers and some melons as squash bugs carry bacterial diseases that will kill these plants. Please check your plot carefully. They tend to congregate near the base of the plant and the underside of leaves.

How to Control

I use a yellow pail filled with soapy water and knocked the squash bugs into the liquid to drown. Then I hand-pick the copper-colored eggs from the leaves and finally I spray with neem oil, which is in the shed.

You can’t just use neem oil. It has to be a three-prong attack.

Please stay on top of this. Otherwise there will be yellowing and eventually wilting of the entire plant as these bugs carry bacterial diseases that are deadly to the plants they infest.
