Our hilly terrain presents a challenge to uniform irrigation that can result in uneven vine health and vigor. The presentation will include:
– why uniformity is important (even fertigation, over/under watering, uniform vine vigor, etc.)
– irrigation effectiveness is affected by terrain
– testing for uniformity, testing for sediments
– pressure and flow, assessing pumps, pressure-compensating emitters

Drone Spraying Field Demo with FarmX and Ag-Bee
at Ascona Vineyard
FarmX will demonstrate drone based spraying in vineyards. You will see an actual demo of an aerial drone spraying a vineyard (note, water will be sprayed). You will learn the state of the drone spraying industry, capabilities and limitations of drone spraying, what kinds of vineyards drones are most suited to spray, and typical spraying costs. You will also learn how to get started with drone spraying, coverage rates, and application rates that are possible with drones. A single aerial drone can optimally spray up to a 40-acre vineyard, including fungicides, foliar fertilizers and pesticides.
And this will give us an opportunity to get together and compare notes before harvest.
FarmX, headquartered in Mountain View, also provides capabilities for grape monitoring and irrigation automation using a unique soil moisture probe that measures a volume 4′ in diameter, and other crop parameters to provide irrigation recommendations based on the local weather and soil type. In addition, you will hear about how FarmX automates valves, pumps, and more to enable deficit and short cycle irrigation. FarmX ipartners with Ag-Bee, LLC to provide aerial drone spraying services for nut, vegetable, wine and table grapes growers and more.

Storm Preparedness and Damage Recovery, Plus Funding for Vineyard Conservation Practices
– with Rich Casale and Drew Mather, NRCS
We have had some fierce storms, a lot of rain and high winds, in the past couple of months. Rich Casale and Drew Mather of the local NRCS office (Santa Cruz County) will address:
– storm preparedness;
– what to do (and not to do) in an emergency if you experience storm damage
– storm damage recovery practices and/or strategies;
– and NRCS/Farm Service financial and technical assistance programs throughout the year for conservation and other management practices.
You may have had trees uprooted on your property that have compromised soil retention, drainage or erosion issues, etc. And if not yet then it will still be good to know what to do to avoid and address in the future. Plus, you’ll find out about some valuable funding assistance through the NRCS for a wide range of conservation practices, of which some of our growers have benefited from over the years.
If you have particular damage issues that you are interested to have addressed during the program you can email Rich ahead of time at richcasale3@gmail.com .

Harvest, 2019
Spring was long and cold and brought a lot of rain throughout the region and with it pressure from mildew and other fungal diseases in many vineyards. Rain during bloom in some vineyards will affect croploads. For those vineyards that started bloom after the rains the crop is looking very strong. In many vineyards bloom was late, and then budbreak, and then veraison. Veraison started in many vineyards in August, and harvest is later than usual. Although an unusual growing season for many it has resulted in plentiful croploads with excellent fruit. Many growers are enthusiastic about the 2019 vintage.
Harvest 2018
The 2018 vintage by and large is seeing excellent crop loads and stellar quality. Cool temps from early Sept. on allowed for long hang time and for many a delayed harvest that developed fruit flavors. However, the myriad microclimates of the mountains makes it difficult to generalize, and a warm August precipitated ripening and harvest for some. Growers and winemakers are excited by the 2018 vintage and what it promises in the bottle!
