It's the scary season for this invasive plant

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.

Those dark purple berries are toxic to humans, dogs, livestock and other mammals. The birds who eat and carry them around, conveniently reseeding the plant, somehow are immune to the poison. Gardeners, you may be growing this plant for a lot of reasons -- it IS pretty, with its white flowers and red stems -- but if it's near where children or dogs walk or play, please reconsider.

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."

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

Pokeweed is invasive and a survivor. Its seeds remain viable for up to 50 years, according to the UC IPM page. Once established, it has a long taproot and doesn't require regular water. It dies back after the first frost, then re-sprouts in spring.

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.

Dig In: Garden Checklist

For week of Sept. 24:

This week our weather will be just right for fall gardening. What are you waiting for?

* Now is the time to plant for fall. The warm soil will get these veggies off to a fast start.

* Keep harvesting tomatoes, peppers, squash, melons and eggplant. Tomatoes may ripen faster off the vine and sitting on the kitchen counter.

* Compost annuals and vegetable crops that have finished producing.

* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.

* Fertilize deciduous fruit trees.

* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.

* Transplant cabbage, broccoli, kale, Brussels sprouts and cauliflower as well as lettuce seedlings.

* Sow seeds of California poppies, clarkia and African daisies.

* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.

* Divide and replant bulbs, rhizomes and perennials. That includes bearded iris; if they haven’t bloomed in three years, it’s time to dig them up and divide their rhizomes.

* Dig up and divide daylilies as they complete their bloom cycle.

* Divide and transplant peonies that have become overcrowded. Replant with “eyes” about an inch below the soil surface.

* Late September is ideal for sowing a new lawn or re-seeding bare spots.
