My hebes won't flower

I have many varieties of hebes in my garden. They have been planted for between 3 and 4 years. The problem is they will not flower. I have cut them back but still nothing. I get the odd flower from some but that is very rare.

Hebes are extremely hardy plants that do not require a lot of special attention. Stop trimming your hebes as it is likely you are removing the flowering stems before they get a chance to flower.

There are many different hebes; some are spring and summer flowering, others autumn and winter flowering. If you know what variety you have planted, you will be able to find out when they flower.

Trim plants after flowering to encourage new growth and flowering. Mulch around plants in spring to help keep the roots cool and moist.
