It's National Pollinator Week and you might be wondering where your pollinators are. 

“I'd love to attract honey bees, bumble bees and other pollinators, but what can I do?" you ask. "Where do I start?"

So we asked world-class garden designer Kate Frey of Hopland, a two-time gold medal winner at the prestigious Chelsea Flower Show in London, co-founder of the American Garden School, and co-author of The Bee-Friendly Garden (with Professor Gretchen LeBuhn of San Francisco State University) for her advice.

Few people are as passionate about pollinators and pollinator gardens as Kate Frey.

We heard her speak at the Native Bees Workshop last September at the Hopland Research and Extension Center, Mendocino County, and we tagged along on her guided tour of her one-acre spectacular garden at her Hopland home, where she and husband Ben and assorted pets reside. We also heard her speak on "Gardening for Bees, Beauty and Diversity" May 14 at Annie's Annuals and Perennials, Richmond.

Kate is highly sought as a speaker, whether it be at sustainable landscape programs,  gardening seminars,  or at UC workshops. Among her affiliates: University of California entomologists Robbin Thorp, distinguished emeritus professor at UC Davis, and Professor Gordon Frankie of UC Berkeley. (Read what Frankie has to say about native bees.)

So, what to do first? Kate offers these tips:

Create healthy gardens that require no pesticides by using the right plant, right place approach, add quality compost to all plants and irrigate adequately. 

Choose appropriate plants for your water, soils, exposure, climate, and if annuals, season!

Think in terms of abundance, not minimalism. Plant at least a 3-x-3 foot area of each plant, or repeat the same plant throughout your garden. Each honey bee colony needs an estimated one-acre of flowers to support it.

Goal: 12 months of bloom. Plants can be annuals, perennials, shrubs or trees.

Make sure plants do offer floral resources, as many landscape plants don't.

Have patches or repeated plants of the same flower.  Honey bees practice floral constancy.

Include water for honey bees

Sunny spaces are the best.

Provide bee-block nests and mulch-free nest sites for native bees.

All great advice! Indeed, we should think of pollinators as not mere "visitors," but permanent residents. Plant what they like and they will come. To ensure that they will stay stay, leave soil bare for ground-nesting bees, such as bumble bees. And don't forget those bee-block nests, or bee condos, for leafcutter bees and blue orchard bees.

Asclepias milkweeds, all

Asters, Aster x frikartii 'Monch' A. ericoides ‘Monte Casino', A. laterifolius Lady in Black' 

Agastache, ‘Black Adder' ‘'Purple Haze' Rosy Giant' ‘Tutti Frutti' and many more

Arbutus unedo, Strawberry tree

Arctostaphylos, most Manzanita

Calamentha nepetoides, Calamentha

Ceanothus, all California lilac

Epilobium, California fuchsia. There are many good cultivars

Eriogonum fasciculatum, California buckwheat

Gaillardia, Blanket flower

Helianthus bolanderi, native shrubby sunflower

Monardella villosa,  Coyote mint

Nepeta faassenii, all nepetas,  Catmint

Origanum,  flowering oregano, all. Origanum 'Santa Cruz' and 'Bristol Cross' are good.

 "Bee gardens make people happy," Kate Frey and Gretchen LeBuhn write in their book. "Whether you enjoy a brilliant chorus of saturated color, a tranquil sanctuary from the busy world, or a hardworking edible garden, there is a glorious, flower-filled bee garden waiting for you."

Yes, we all need a happy place. And so, too, do the pollinators.
