Avenue tree cultivation focuses on growing varieties of trees that are suitable for planting along avenues, roads, streets, but also in parks and gardens. The trees are typified by their characteristic upright shape. This is achieved by training and pruning the trees during the initial years to obtain a branch-free lower trunk, good secondary growth and a full crown.

Hardening off

Towards the end of the growth season (end of August/early September), the focus is on accumulating reserves in preparation for winter. The so-called hardening off process begins. The transport of minerals from the leaf to the trunk and the side branches demands extra availability of potassium. To supply sufficient potassium at the end of August/early September, Soiltech developed the foliar fertiliser Optima Leaf-K. The product contains easily available potassium in a high concentration (28% K2O). Optima Leaf-K promotes secondary growth and increases the hardiness of the crops.

Advice in this stage:

Foliar application 3 x - Optima Leaf-K: 5 litres/ha (every 14 days)

Stage 7 Leaf drop
Stage 7

Leaf drop

As soon as the natural process of leaf drop has started, it is recommended to promote it. Applied in high concentrations, the copper foliar fertiliser Optima Leaf-Cu+ has the side effect of accelerating leaf drop in autumn. Spraying the leaves of dry trees during sunny weather benefits the desired result. Take care to time this treatment well – only start foliar application when 10% of the leaves have dropped. Treating too early with Optima Leaf-Cu+ will stop transport of reserves for winter hardiness prematurely.

Advice in this stage:

Foliar application 1 x Optima Leaf Cu+: 6 litres/ha
