Good Bad Bugly
Invite Your Friends to the Party
By Mary Tran
UCCE Master Gardener of El Dorado County

OK, so you planted a garden so you could have fresh veggies to eat and a nice place to hang out. But then those pesky aphids and caterpillars and beetles and scale-insects and their kin arrived and made a mess. Just like last year.

Naturally, you don’t want to spray your plants with nerve poisons and other toxins. Who wants that stuff in the garden? But what can you do about the pests?!

Let’s be practical. First, avoid attracting pests; take it easy when applying fertilizers, and keep the garden tidy. Do this be cleaning up fallen fruit, removing the weeds, etc. Second, welcome the “natural enemies” of your pests to the garden and let them do the work for you. I call these insects the Friends of the Garden. Some act as parasites, laying their eggs in the eggs and caterpillar bodies of other insects. Some are predators - they eat your pests for lunch.

How to welcome the Friends of the Garden to your party?

Avoid spraying them with pesticides. Learn to recognize your guests. Check ipm.ucanr.edu > Publications > Landscape and Garden Resources > Natural Enemies Gallery for photos of the bugs you want to welcome. In addition, plant the trees and bushes that will support the Friends year round. The University of California has provided a list of plants that, together, are recommended for providing this support. See “Natural Enemies Handbook,” by M.L. Flint and S.H. Dreistadt, published by University of California Press, 1998, page 46. From this list, I have picked out some that do best with our dry summers. Here they are:

Yarrow, Montrose Rose
Yarrow, Montrose Rose
To cover winter and early spring:
Ceanothus, also called California wild lilac. Can be grown as a bush or tree. Has white to blue flower spikes in spring. Likes full sun, doesn’t like to have its feet (roots) wet too much, and can handle winter frost.

Cercis, or Redbud. Tree 25-35 ft. tall. Has abundant pink bloom in the spring. Likes full sun but some shade is ok.

To cover spring and summer:
Achillea, or Yarrow. Low perennial. Has generous bloom in pink and purple. Likes full sun. Good for cut flowers, but leave some for our Friends of the Garden.

Coffeeberry. Evergreen shrub, up to 15 feet tall, 8 ft. wide. Has red-black berries. Is not fussy about soil, likes full sun but is shade tolerant.

Toyon. Large shrub/tree, to 25 ft. tall. White flower clusters in summer, red berries in winter. Likes full sun but is ok with some shade.

To cover fall into winter:
Baccharis or Coyote brush, also called chaparral broom. Grows as a ground cover or as shrub 3 to 9 ft. tall. Flowers are white to yellow. Is deer- and possibly fire-resistant. One of the few winter bloomers.

If you cannot find these plants at your favorite nursery, you might take advantage of the special plant sales offered by UC Davis Arboretum (http://publicgarden.ucdavis.edu/plant-sales), the California Native Plant Society (https://www.eldoradocnps.org/news-events/plant-sales), and the UCCE Master Gardeners of El Dorado County (http://mgeldorado.ucanr.edu/Calendar/).
