CNGA's 6th Annual Field Day at Hedgerow Farms

Hedgerow Farms hosted the 6th annual California Native Grasslands Association (CNGA) Field Day on Friday, April 19th. It was a sold-out event with over 130 people in attendance, including the many volunteers who help make the event happen. Thank you to everyone who attended and also thank you to the volunteers! A special thanks to the sponsors: Bay Natives, Delta Bluegrass, Dow AgroSciences, Pacific Coast Seed, and S & S Seeds. 

It was a full day with two tours, lunchtime speakers, a visit to a nearby restoration site, and a social hour at the end with fantastic music from the Putah Creek Muckrakers (thanks!). Below are some of the highlights.

Walking Tour

The walking tours focused on small-scale restoration and landscaping projects and techniques. We walked through fields of milkweed, Asclepias sp., and spotted a monarch caterpillar on Asclepias speciosa. Monarch caterpillars feed exclusively on milkweed plants.

One of the stops highlighted several species that are often used when replacing traditional lawns with native, drought tolerant alternatives. These include Carex praegracilis and Carex pansa which look the closest to traditional lawns. We also looked at a native meadow which is more natural look.

Kimora Ward with UC Davis talked about native pollinators at another stop on the tour. She is with the Neal Williams Lab and is looking at  which pollinator plants preform best in our area. She and her team are monitoring the pollinators that are visiting different native forbs, including plots on our farm. She has also been working on developing an ideal pollinator mix. 

Straw Bale Tour

The second tour loop was a driving tour on straw bales to look at some examples of large-scale restoration projects. There was a stop at a roadside to view a hedgerow and roadside planting. We also looked at the contrast between vegetated canals and "clean" canals as well as a tailwater pond. Both vegetated canals and tailwater ponds improve water quality and reduce soil erosion.

This tour spent a lot of time in a large restored area on the west side of the farm. The restoration on this site began in 1990. We have been using it for grazing, seeding and herbicide trails since then. The area has some Stipa (Nassella) pulchra, purple needlegrass, that are over 20 years old.

Richard King talking about rangeland management.

Richard King is a retired USDA-NRCS rangeland specialist. He spoke about the importance of managing rangeland for long-term health. He argues that more attention needs to be put on building the health of the soil to create healthier rangelands and that grazing can be a useful and beneficial way to manage native grasslands.

Lunchtime Speakers

At lunch there were several featured speakers. John Greenlee works extensively with natives and naturalized plants in landscaping applications. He is the author of The American Meadow Garden: Creating a Natural Alternative to the Traditional Lawn. He highlighted several species and varieties he likes to work with, inclduing the "sexy" Bouteloua gracilis 'Blonde Ambition.'

Dr. Paul Aigner,  co-director of the UC McLaughlin Natural Reserve, spoke about the unique challenges that come with managing sites with serpentine soils. 

Rachael Long, Director of the Yolo County UC Cooperative Extension gave her annual update on beneficial insects and hedgerows.

Field Visit: Citrona Farms

The afternoon field visit was to a restoration site that was seeded with native grasses in the early 2000s.  The site was burned in September of 2012 and the native grasses have recovered very well. Dr. Drew Rayburn with UC Davis talked about his research on monitoring restored grasselands. He is monitoring many sites throughout Northern California including this one.  He is also developing and testing new cost effective ways of implementing restoration in grasslands.

Thank you again to everyone who attended! We hope to do this again next year. Thank you Phil Hogan for allowing us to use his wonderful photos. 

Spring Is Here!

It has been way too long since our last post! Last fall was a very busy planting season, there were orders coming in regularly all the way through the beginning of this year. While that was fabulous for business, it meant that the blog fell to the bottom of the to-do list. The farm received very little rain so far this winter, but a lot of things are still greening up and beginning to bloom. Here are a few photos from the past week:

The first bloom on the Ray Hartman Ceanothus

Lupinus albifrons, silver bush lupine, is one of the first flowers to bloom

Calandrinia ciliata, red maids, is another early blooming native that likes disturbed soils

Phacelia tanacetifolia, lacy phacelia

Layia chrysanthemoides, smooth tidy tips

A field of Achillea millefolium, yarrow

We also have lots of flowers available in plug plants from our nursery:

Our on-site nursery is full of great looking plants

Clarkia purpurea, purple clarkia

Spring is a great time to plant plug plants.  They will need some source of water until they get established. Some of the species not shown that we have include: Symphyotricum chilens (Aster chilensis), California aster; Eschscholzia california, California poppy; Grindelia camporum, gumplant; Oenothera elata ssp. hirsutissima, evening primrose; and Sisyrinchium bellum; blue eyed grass. Please contact us if you would would like pricing or availability.

Clarkia concinna, red ribbons

Monardella villosa, coyote mint

Madia elegans, common madia

The grass fields are also starting to flower:

Nassella pulchra, purple needlegrass, from Malibu

Poa secunda, one sided blue grass from the
Carrizo Plain National Monument
