Key Early-Season Treatments for
Tree Nut Health and Yield
As growers wrap up their postharvest
nutrition programs and
preparation for the dormant
season, it's a good time to start
planning for the year ahead and
looking at post-dormancy
treatments and activities to ensure
a successful 2025 season. A strong
start in the spring will set the
stage for healthy tree growth
and higher yields.
" In spring, nut set is especially
important, so applying calcium,
boron and zinc at pre-bloom, full
bloom and petal fall will set trees up
for success, " said Francisco Rivera
Guerrero, agronomy and
formulations manager at OMEX®
USA. " Regional deficiencies in
copper, iron and manganese are
also critical to address with early
spring nutritional sprays. "
Supporting Tree Health
Francisco offers direction regarding
a few products that can help
growers set their trees up for a
healthy and profitable season.
Cell Power® Slyce®: When
trees come out of dormancy, it's
essential to keep the soil near
field capacity for optimal water
and nutrient uptake. Using
Slyce® early on aids in water
penetration and movement into
the root zone, where it's needed
most. Once trees reach about
60-75% full leaf-out, they begin
absorbing water and nutrients
from the soil on their own.
Cell Power® LifeOmex®: When
temperatures are colder than
usual, or there's a lack of winter
rain and salinity becomes an
issue early in the season,
LifeOmex® helps reduce the
damaging effects of Reactive
Oxygen Species (ROS), which can
harm crop cells and reduce
photosynthesis. LifeOmex is also
beneficial for crops with heavy
loads, as it helps reduce nut
abscission layers after bloom,
leading to better nut retention.
Boron and Zinc Products:
Boron and zinc are essential in
the spring. Boron supports
pollen tube formation and
germination, which increase nut
set, while zinc is crucial for auxin
biosynthesis, which plays a key
role in flower primordia
formation.
Cell Power® Cytomex™:
Applying Cytomex™ in the fall
before dormancy can help
increase return fruitfulness for
the following season. Leaves
tend to grow larger and earlier
in the season with Cytomex™,
which is a blend of seaweedbased
metabolites that support
various growth pathways. It
maximizes root branching and
growth, creates balanced
vegetative growth in spring and
enhances bloom and bloom
retention.
Cell Power® SizeN®: SizeN® is
most beneficial from late bloom
to nut set, applied once a month

at a rate of 1/2 gallon per acre. It
encourages root branching,
which creates a robust support
system for the tree. Additionally,
it increases nut size, weight,
yield and the consistency of nuts
produced.
" Most of our products blend well
with other nutrients and
chemistries, allowing growers to
integrate them into their programs
flexibly, " Francisco said.
He went on to recommend that
growers continually evaluate the
earliness and vigor of their trees
following the application of any of
these products.
" After the typical nut-drop period,
reduced nut abortion and increased
retention indicate positive
responses to our products, which
can lead to higher potential yields, "
he added. " Early-season preparation
is crucial, but our goal is to maintain
yield through the entire season. "
To achieve the best results,
Francisco recommends a year-long
OMEX® program, as abiotic/biotic
factors rob the crop of its full
genetic yield potential. The purpose
is to limit these losses and maintain
the yield potential throughout the
growing season.
