Beware: Pokeweed berries are toxic

Ghosts, haunted houses, bats and other scary images are in season. But do you know what really makes me shudder? Seeing ripe pokeweed berries at child height.

Usually pokeweed berries grow in grapelike clusters, but
sometimes they appear in clumps like this.

American pokeweed ( Phytolacca americana ) is an invasive plant with a long history. It's a native of eastern and southeastern states that has spread over the years to parts of California, including the Central Valley, according to the UC Integrated Pest Management program, which just last week updated its public information page on pokeweed.
"Pokeweed is found in riparian areas, oak woodlands, forest edges, fence rows, forest openings, pastures, under power lines, disturbed areas, vineyards, orchards, cultivated fields, parks, and ornamental landscape," the IPM pokeweed page notes. You'll notice that a lot of those sites are hangouts for birds.
The plant has some uses: The berries' juice make wonderful dye, apparently, and also has been used for ink. Historically the leaves were considered edible; one of its alternate names is "poke salad."
But UC IPM is unequivocal in its warning against consuming any part of this plant:
"Although sometimes eaten, the entire plant is poisonous and should be considered with extreme caution. The leaves and stems of young pokeweed plants can be ingested only after repeated blanching; without proper preparation, pokeweed can cause a variety of symptoms, including death in rare cases."

A single pokeweed plant can produce up to 7,000
seeds annually.

Say you've discovered one of these plants in your garden and want to cut it down. First of all, don't put any of it in your compost bin or the green waste container. And wear gloves, since the ripe berries burst easily and stain fingers. Put a large trash bag over the stem with the ripe berries, and then cut the stem so the berries fall into the bag, not on the ground. When you have cut off all the berry clusters, tie the bag and put it in the trash bin. Then dig out the rest of the plant with a shovel, going after the taproot, and discard that, too.
In the spring keep an eye out for new sprouts. As with any invasive weed, the best organic advice is "Just keep digging."
Chemical controls are possible, UC IPM notes, but that's mostly for agricultural eradication; if you're curious, the instructions can be found at the page linked above.
And if a child eats the berries -- stains around the mouth will be a giveaway -- contact Poison Control immediately. There's a poison control for pets , too.

Garden Checklist for week of Jan. 19
Dress warmly in layers – and get to work:
* Apply horticultural oil to fruit trees to control scale, mites and aphids. Oils need 24 hours of dry weather after application to be effective.
* This is also the time to spray a copper-based oil to peach and nectarine trees to fight leaf curl. The safest effective fungicides available for backyard trees are copper soap -- aka copper octanoate -- or copper ammonium, a fixed copper fungicide. Apply either of these copper products with 1% horticultural oil to increase effectiveness.
* Prune, prune, prune. Now is the time to cut back most deciduous trees and shrubs. The exceptions are spring-flowering shrubs such as lilacs.
* Now is the time to prune fruit trees. Clean up leaves and debris around the trees to prevent the spread of disease. (The exceptions are apricot and cherry trees, which are susceptible to a fungus that causes dieback if pruned now. Save those until summer.)
* Prune roses, even if they’re still trying to bloom. Strip off any remaining leaves, so the bush will be able to put out new growth in early spring.
* Clean up leaves and debris around your newly pruned roses and shrubs. Put down fresh mulch or bark to keep roots cozy.
* When forced bulbs sprout, move them to a cool, bright window. Give them a quarter turn each day so the stems will grow straight.
* Browse through seed catalogs and start making plans for spring and summer.
* Divide daylilies, Shasta daisies and other perennials.
* Cut back and divide chrysanthemums.
* Plant bare-root roses, trees and shrubs.
* Transplant pansies, violas, calendulas, English daisies, snapdragons and fairy primroses.
* In the vegetable garden, plant fava beans, head lettuce, mustard, onion sets, radicchio and radishes.
* Plant bare-root asparagus and root divisions of rhubarb.
* In the bulb department, plant callas, anemones, ranunculus and gladioli for bloom from late spring into summer.
* Plant blooming azaleas, camellias and rhododendrons. If you’re shopping for these beautiful landscape plants, you can now find them in full flower at local nurseries.
