Winter treatments for fruit trees and other deciduous varieties offer both curative and preventive benefits. As experienced orchard managers know, these applications eliminate overwintering insects like eggs and adults, significantly reducing the risk of parasitic attacks by clearing out parasites.
Opt for paraffinic oils or rapeseed oils, applying them as a thorough spray over the entire foliage once or twice during winter. These trusted solutions come in chemical or organic farming-approved forms.
The precautions for use remain consistent across products:
– Avoid application during frost, rain, or wind.
– Do not eat, drink, or smoke during treatment.
– Wear protective gear (gloves, waterproof clothing, mask) before mixing the product with water.
– Strictly follow dosage instructions to avoid waste, pollution, or plant damage.
– Rinse equipment thoroughly after use.
– Never dispose of leftover solution down the drain.
– Do not store unused solution; it may degrade.
– Wash thoroughly after treatment.
The arboreal white (tree whitewash) is ideal for trunks and the base of large branches. First scrub with a hard-bristle brush, then apply with a wide brush.
Bordeaux mixture is especially recommended for peach trees to prevent leaf curl. Apply two treatments: one at leaf fall and another at winter's end when buds start to swell.
Apple tree in winter: Always treat outside frost periods.
