How to cut large branches

Tools

• A good pair of pruning shears is probably one of the most important tools. Cuts up to 3/4 inches in diameter may be made with them

Tools

• Lopping shears are similar to pruning shears, but their long handles provide greater leverage needed to cut branches up to 11/2 inches in diameter

Hedge Shears

• Hedge shears are meant only for pruning hedges, nothing else. They usually cut succulent or small stems best. Cut multiple small stems with each stroke.

Hand Saws

• Hand saws are very important for cutting branches over 1 inch in diameter. Many types of hand saws are available. Special tri-cut or razor tooth pruning saws cut through larger branches — up to 4 inches in diameter — with ease

Pole Saws

• Pole saws allow for extended reach with a long handle, but they must be used carefully as it’s difficult to achieve clean cuts with them

When to prune

• Spring flowering shrubs & trees – right after blooming– Flower on last years growth

• Summer flowering shrubs & trees – in dormant season– Decrease opportunity for disease
