Why february is the decisive month for your fruit trees
February may seem like a quiet month for your fruit trees, but it's actually a crucial period for their health and future harvests.
A hidden enemy lurks
While your trees appear dormant, they're harboring a stealthy army of pests and diseases under their bark and in crevices. Eggs of aphids, scales, mites, and fungal spores like taphrina, powdery mildew, and scab lie in wait, ready to feast once sap flow resumes and temperatures rise.
A simple yet powerful solution
One often overlooked gesture can make all the difference: winter oil treatment, also known as horticultural oil or colza oil. This thin film coats the bark and branches, suffocating eggs and young larvae while limiting fungal growth.
When to Apply: February is the ideal window, before buds swell and leaves emerge. In warmer climates, this may occur earlier; in colder regions, wait until late February or early March, when the risk of severe frosts diminishes.A clean canvas for treatment
Before applying oil, thoroughly clean your trees. Remove fallen leaves, decaying fruit, and weak, diseased branches. For heavily infested trees, gently brush off moss and lichens from the trunk without damaging the bark.
Choosing the right products
- Horticultural oils or colza oil
- Savon noir liquid soap for better mixing
- Bordeaux mixture or white arboricole for fungal control
Effective application techniques
Pulverize the solution gently, starting at the trunk and working up to the branches. Aim for a light coating, avoiding excessive runoff. Apply on calm, dry days, without wind or impending rain.
Pruning as an ally
February is also a prime time for gentle pruning. Remove dead, crossing, or poorly angled branches. Disinfect your tools between cuts to prevent spreading disease. For larger diameter cuts, apply a wound dressing to protect against fungal infection.
Dont miss this window
February is the last chance to address these issues before the growing season begins. Neglecting this crucial step may result in a disappointing harvest plagued by pests and diseases.
