Trim lavender after it has flowered

Sub shrubby perennials such as lavandula (lavender) and santolina (cotton lavender) can also be trimmed once flowering is completed.

Lavender stems become brittle and unproductive with age and, even with regular annual pruning, it’s a good idea to raise new plants from seed after seven years with eventual replacement in mind.

Dwarf lavender munstead hedge lines either side of the driveway, attracting countless bumblebees from June to late August.

Now it’s almost flowered-out for the year, the annual trim is due.

This pruning is reasonably severe without cutting into the old wood, leaving some new growth in place.

Rosemary bushes dotted around the garden serve the kitchen and are just great to brush past, releasing their fragrance.

Now is a good time to reduce rangy specimens, whose soft tips are often caught by winter frost anyway. Cotton lavenders grown in this garden need a little protection too.

The recent wind and rain has flattened some of the plants to ground level, giving us full view of the centres and embryo shoots. Tempting though it is to chop away all top growth and reveal them now, the cautious approach is a decent trim, leaving a protective layer in place.

No need to waste the prunings from these fragrant perennials either, rub them into small pieces, sew together in a sachet and keep as a permanent reminder of summer!
