Shelling Out Useful, Real-World Almond Knowledge

As we continue to move into almond bloom, the time to start is now. Every month brings new needs and new possibilities to your orchard, so we’ve done our best to put together the following advice for your almonds.

Avoid Boron During Open Pollination

During pollination, pollen tubes are trying to reach the ovule of the flowers to form seeds. Boron is a critical element for pollen tube initiation and elongation. Foliar boron applications in almonds and other deciduous crops have been shown in university research to enhance the pollination and fertilization processes with the end result being higher yields.
The preferred timing for foliar boron application in almonds is post-harvest and again prior to bloom in the spring. Waiting until bloom to make foliar boron applications is too late and no positive response would be expected from this application timing.  

The best practice for spring-applied foliar boron is to apply at pink bud and discontinue once full bloom has set in.



Making Waves with Nutritional Efficiency 

FOLI-GRO® TIDALWAVE is a seaweed-based nutritional product that can act as a food source for soil microbial populations.

Fight Bloom-Time Diseases the Right Way

Be Mindful of your FRAC
With bloom fast approaching, it's time to start thinking about how you are going to protect your flowers and young, developing fruit. Make sure you are selecting the correct foliar nutrients and fungicides. Your Wilbur-Ellis representative will work with you to ensure that you are targeting the right disease at the right time and with the right product.
Every fungus and disease is different, so make sure you are identifying the disease correctly. Double check that you are using the proper mode of action and rotating FRAC groups between sprays to minimize the potential to develop resistance. Ask your Wilbur-Ellis representative to help develop the most appropriate early-season disease prevention strategy for you, with a focus on minimizing the development of disease resistance

Possible diseases include:
  • Brown Rot
  • Shot Hole
  • Scab
  • Jack Rot
  • Anthracnose

Bee Mindful

Do your research BEFORE spraying– there is now an excellent new tool where you can register and identify beehives near you. Be sure to check out this new tool at before you spray.

Wilbur-Ellis advocates to be cautious and avoid application while pollinators are actively foraging, if at all possible. Please work with your local Wilbur-Ellis representative and local beekeepers regarding this topic.
If you choose to make a spray application, do so during bee periods of minimal bee activity, such as nighttime or when temperatures are cool.

Early Season Root Flush and Fertility

Almond root activity begins in advance of bloom – once trees develop a canopy, they become dependent on new root growth for water and nutrient uptakeCalcium, a secondary macronutrient, promotes new root growth only after being taken up behind the root cap of new feeder roots.

Liquid calcium fertilizers in combination with products such as NUTRIOTM UNLOCK and TILL-IT® 707 may further stimulate early season root growth. 
  • NUTRIO UNLOCK provides beneficial rhizobacteria that colonize new root growth, enhancing nutrient uptake and providing improved root vigor.
  • TILL-IT 707, a combination of slow-release nitrogen, protein hydrolysate, seaplant extract, and PURIC humic acid, is a new product designed to stimulate soil microbial populations and provide further aid to the tolerance of abiotic stresses.

Prepare to Succeed

During Taco Leaf Stage
As we move into full leaf expansion, your trees are at their highest demand for nutrients – this is a critical time to start a soil fertilization program. Root flush is also occurring at this point in time, putting the tree in a massive growth phase. If infection with phytophthora has been a problem in the past, you will need the right products to prevent the spread of this disease to your new root growth. Work with your Wilbur-Ellis representative to find the right protection and nutrients for your orchard’s needs.
