How to Prune Garden Shrubs?

Garden shrubs can be generally divided into view of three types as flower viewing shrub, fruit viewing shrub and branches viewing shrub, and different shrubs should taken different . pruning methods.

Shrubs grow for viewing flowers, commonly there are jasminum nudiflorum, forsythia, xanthina, Bauhinia, cloves and so on, and their flower buds are formed on the branches in the first year, so the prune job should be carried out after flowering in May and June.

Summer pruning should be carried out mainly with purpose of thinning branches and trimming shapes, cutting out crossed branches, leggy branches, dense branches, insect pest branches and dead branches, to facilitate ventilation and light transmission, so that make nutrient more concentrated; Remained flower branches may be shorten thus to help them grow more rapidly, which is also benefit for its flowering in the coming year.

For summer flowering shrubs such as roses, hibiscus, Chinese wolfberry, crape myrtle, etc., which are generally blossomed out on new shoots grow in the spring of that year, so the pruning job should be carried out after defoliation in the winter. Cut off too dense branches, dead branches and pest branches etc.

When thinning branches the stubs can not be left too long, generally should cut begin from the branching point, cutting with an inclination angle of 45 °, the incision should be kept smooth. Weak branches should be cut heavily while heavy branches should be cut lightly, 4-6 buds may be remained on each branch, the rest be cut off partly.

When pruning shrubs growing both for viewing flowers and viewing fruits, keep branches 5cm-20cm left, the rest part be cut off, thus to facilitate it grow more new branches in the next year.
