Sacramento hosts national begonia convention

Hundreds of rare plants available to the public in Sept. 7 sale

It’s a begonia lover’s dream: Hundreds of plants and dozens of experts all in one place.

And next week, that place is Sacramento.

For the first time in four decades, Sacramento will host the American Begonia Society’s national convention, to be held next week at the Crowne Plaza Hotel Northeast. A gigantic plant sale and huge judged show will be open free to the public next Saturday, Sept. 7.

Due to the convention, the Joan Coulat Chapter’s annual Sacramento show and sale will not be held that weekend at the Shepard Garden and Arts Center. Instead, make plans to go to the Crowne Plaza and take your pick from the spectacular assortment of sale plants available as well as admire the award-winning specimens in the national show.

Sacramento hasn’t hosted the national convention since 1978. A lot has happened in the begonia world, including the discovery of new species and the hybridization of thousands more.

“We’ll have speakers from Australia, China, Indonesia,” said show chair Wendy Corby, a longtime Sacramento begonia grower. “People will find out what’s going on with begonias worldwide.”

Two more speakers from China were scheduled to appear at the convention, but were denied visas, she noted.

Begonias have fans everywhere because there are so many different kinds, Corby explained. With more than 1,800 species, it ranks among the largest and most diverse plant families on Earth.

California is a major begonia-growing state. “We have more branches of the (American) Begonia Society in California than any other state,” Corby said. “Texas is second. The reason they’re so popular here is we can grow them outdoors year round. Otherwise, you have to have a greenhouse or grow them indoors. Begonias just love it here.”

Begonias come in a wide range of species such as this angel wing variety
from Wendy Corby's collection.
Show organizers brought in top-class plants from major nurseries and hybridizers for the sale. That includes 300 plants from Kartuz Greenhouse in Vista and 800 from Warren’s Nursery in Los Osos. Dozens of hard-to-find miniature terrarium begonias will be available. Local growers also donated hundreds of their own propagated plants

For the public, show and sale hours are 10 a.m. to 4 p.m. Saturday, Sept. 7. Crowne Plaza Hotel Sacramento Northeast is located at 5321 Date Ave., Sacramento, just off Interstate 80 at Madison Avenue.

Co-hosted by the Sacramento and San Francisco chapters, the convention starts Monday with tours, seminars and speakers each day through Sept. 7. Among the featured speakers are Ross Bolwell, who presents “Begonia Breeding the Aussie Way,” and China’s Wen-Ke Dong, who will tell how “All Roads Lead to Begonia.” Both will be part of Wednesday evening’s programs. Convention registration is needed to attend seminars and tours.

Dig In: Garden Checklist

For week of March 26:

Sacramento can expect another inch of rain from this latest storm. Leave the sprinklers off at least another week. Temps will dip down into the low 30s early in the week, so avoid planting tender seedlings (such as tomatoes). Concentrate on these tasks before or after this week’s rain:

* Fertilize roses, annual flowers and berries as spring growth begins to appear.

* Knock off aphids with a strong blast of water or some bug soap as soon as they appear.

* Pull weeds now! Don’t let them get started. Take a hoe and whack them as soon as they sprout.

* Prepare summer vegetable beds. Spade in compost and other amendments.

* Prune and fertilize spring-flowering shrubs after bloom.

* Feed camellias at the end of their bloom cycle. Pick up browned and fallen flowers to help corral blossom blight.

* Feed citrus trees, which are now in bloom and setting fruit.

To prevent sunburn and borer problems on young trees, paint the exposed portion of the trunk with diluted white latex (water-based) interior paint. Dilute the paint with an equal amount of cold water before application.

* Cut back and fertilize perennial herbs to encourage new growth.

* Seed and renovate the lawn (if you still have one). Feed cool-season grasses such as bent, blue, rye and fescue with a slow-release fertilizer. Check the irrigation system and perform maintenance. Make sure sprinkler heads are turned toward the lawn, not the sidewalk.

* In the vegetable garden, transplant lettuce and kale.

* Seed chard and beets directly into the ground.

* Plant summer bulbs, including gladiolus, tuberous begonias and callas. Also plant dahlia tubers.

* Shop for perennials. Many varieties are available in local nurseries and at plant events. They can be transplanted now while the weather remains relatively cool.
