This tree wash is made from a blend of natural plant and fish oils, it has been formulated to remove the debris, dust, and dirt from trees, the insects then find it very difficult to secure their eggs onto the washed plants and trees thus stopping overwintering plants. Directions for use: For best results apply during calm dry conditions from late September through to February. For fruit trees, treat after leaf fall and prior to bud break in spring. Loosen the cap and squeeze gently to fill the measuring chamber. Mix 50ml per litre of water and apply as a fine spray, thoroughly covering all bark surfaces, ensuring the crooks of branches or stems where pests may harbor are not missed.
