Tree Fruit with Vegalab
Tree fruit is a long-season, high-value crop where disease, mite and nutrition pressure carry over year to year, and where residue and export standards are strict. Vegalab's natural programs are built for low-residue use with zero pre-harvest and re-entry interval where registered.

What the tree-fruit crops have in common
Tree fruit is a perennial system carrying a crop on wood laid down the previous season, which is the fact that governs everything else. This year's yield was substantially determined last summer, when the buds that will flower next spring were initiated. A stress event in July shows up as a light crop the following May, and by then nothing can be done about it — which is why post-harvest management matters as much in these crops as anything done during the season.
Bloom is the pivot point of the calendar. It is when yield is set through pollination and fruit set, and simultaneously when the crop is most exposed: fire blight enters through open flowers, brown rot infects blossoms and stays latent until the fruit ripens, and frost at the wrong moment removes the crop outright. Protecting bloom is the highest-leverage week of the year across apples, pears, cherries, peaches and citrus alike.
The group also shares a fruit-finish problem that nutrition drives. Calcium moves in the xylem and only into tissue that transpires, so it reaches leaves easily and fruit poorly — which is why bitter pit in apples and cracking in cherries are calcium-distribution failures rather than calcium-supply failures, and why soil applications so often disappoint when the fix has to reach the fruit itself.
