Osmanthus in June: monthly care

Osmanthus burkwoodii requires very little pruning to maintain its naturally rounded, dense shape. It flowers in spring on growth made the previous year, so any pruning should be done in May or June, immediately after flowering finishes. Pruning later in summer or autumn will remove the buds that would have flowered the following spring, so timing matters if you want to enjoy the fragrant white blooms. Use clean, sharp secateurs or hedging shears depending on the size of the job. For light maintenance, simply trim back any shoots that spoil the overall shape or extend beyond the desired outline. You can also remove any dead, damaged, or crossing branches to keep the centre of the shrub open and healthy. Osmanthus burkwoodii responds well to clipping if you're growing it as a formal hedge; shear lightly after flowering to maintain a neat profile, but avoid cutting back into very old, bare wood as regrowth can be slow. If your shrub has become overgrown or leggy, you can renovate it by cutting back harder—up to one-third of the overall growth—in May or June. Spread major renovation over two or three years if the plant is very old, tackling one-third of the oldest stems each year to avoid shocking the shrub. Feed and mulch well after hard pruning to encourage strong new growth. If you don't prune at all, osmanthus will still grow happily, but it may eventually become too large for its space and lose some of its dense, tidy habit.
