Welcome to a new decade! Although it’s winter on our farms, there’s still a lot going on…
Recent weather has provided some crucial chill hours to our trees and vines. Chill hours occur when the temperature is between 32°F and 45°F while our trees and vines are dormant. Each variety and type of fruit has different chill hour requirements, which can range from approximately 100-800 hours. We currently have more than 700 chill hours logged on our farms. That’s around 200 hours more than we had at this point last year. January rainfall on our farms is average for the Central Valley. Once the chill hours have been reached and the weather begins to warm, our trees and vines begin to come out of dormancy, signaled by buds and blooms.
Weather in California’s Central Valley has its own unique attributes. One of the things that sets us apart is tule fog. No ordinary mist, tule fog is radiation fog, which forms when humidity is high and the ground is cold with little to no wind. This dense ground fog often forms in the days following rain in the Central Valley, causing sections of very low visibility – often 1/4 mile (.4 km) or less. This low visibility leads to “foggy day schedules” at our local schools as school buses and parents wait for visibility to increase for safe driving conditions.
The trees in our high density orchards have now grown to a point which opens the door to a new method of tree pruning utilizing a platform instead of ladders. In comparison with ladder use, the platform saves time and increases safety for our field crews by eliminating the need to climb up and down a ladder and then move it a few feet to start the process again. The platform is beneficial for many farming activities in our high density orchards, including pruning, thinning, and harvest. We are excited to see how this new piece of equipment will increase our efficiency throughout the tree fruit cycle this year.
High density planting, shown above, allows our farm crews to prune, thin, and harvest the organized rows with greater efficiency. Now that these trees have grown large enough, we will bring in a platform pruning system to prepare them for winter and the coming season. This new method of farming will ultimately result in an even better quality of product and more efficient system of delivery for the California stone fruit system.
Our weather has finally caught up with the calendar. Since Thanksgiving, we’ve received about 2.59″ of rain, which is more than 20% of our annual average. Sunday, a thunderstorm dropped quite a bit of hail in some spots on our dormant farms. The forecast shows no rain through the weekend, with precipitation popping up again toward the end of next week. We’ve had a some foggy mornings this week, which are likely to continue due to ground moisture.
Traditional pruning is quite labor-intensive, and we are always looking for ways to improve upon the process. This year, we are using a pre-pruner in preparation for pruning our grape vines. The pre-pruner thins out excess growth and performs a basic cut on vines, significantly reducing the amount of time crews need to spend on pruning. This should allow crews to more easily access the vines for targeted pruning, making the overall process more efficient.
Over the Thanksgiving holiday, some precipitation finally materialized in our area, allowing us to complete grape harvest just before the rain began. The lack of any early rain this year was highly unusual, but it seems that we’ve gotten back on track. We are removing rain covers in our grape vineyards and pruning in our stone fruit orchards, taking breaks to enjoy “farmer’s holidays” during the welcome rainy weather.
Pruning is in full force in our traditional tree fruit orchards, as pictured above. As you can see, the trees are bare of leaves, allowing our crews to distinguish between older wood and fruiting wood. We will soon begin pruning in our high density planting orchards, which is a slightly different process. Pruning allows us to prepare for the next season by maintaining the shape and structure of the trees.
HMC Farms table grape harvest is rapidly winding down. The weather has continued to cooperate with our harvest, helping to maintain excellent grape quality. It looks like we may finally see some precipitation in the middle of next week. The forecast shows high temperatures in the 60s with some chilly overnight lows to start Thanksgiving week.
