We received a total of 3.39″ of precipitation in the month of January. Compared with the past two years, this January had significantly more precipitation. January 2019 had a total of 2.83″ of rain, and January 2020 saw just 0.77″ in the entire month. We hope that this is a good sign for this year’s annual rain total in the Central Valley.
HMC Farms had the honor of partnering with the California Farmworker Foundation to begin to provide COVID shots to our farmworkers this month. Speaking about the event, Harold McClarty commented, “We have all struggled during these very difficult times. We are very grateful and supportive of all the work this organization has done for farmworkers. It gives us some hope that we will persevere and continue to move forward with our work to support the nation’s food supply.”
Blossoms are opening up in our stone fruit orchards and along the rest of the famous Fresno County Blossom Trail. This is arguably the most beautiful time of the year in the Central Valley, drawing people from near and far to drive or bike along the trail and take in the beautiful pink and white blossoms filling orchards for miles. For more information on the Fresno County Blossom Trail, visit their website here.
We are grafting in some of our stone fruit orchards. If you’ve ever driven past an orchard that looked like a bunch of stumps with only one limb, chances are you’ve seen grafting in progress. Grafting is the process of adding a new variety to existing rootstock. This allows us to harvest the new variety in a shorter timeframe by utilizing the rootstock that’s already in the ground instead of starting from scratch with completely new trees. Look closely at the photo above and you will see what appear to be sticks coming out of the cut portion of the tree. Those sticks are actually called scion wood, and are the June Time peach variety that will soon grow in this orchard. The remaining limb, called the nurse limb, is left on the tree to help keep it alive until the grafted scions are growing well, and it will eventually be removed.
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.
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.
