May in the Garden with Glendoick's Ken Cox

MAY is peak gardening time.  Garden Centres are packed with plants.

Everything is starting to grow now: buds swelling, blossom opening, leaves unfurling.

You might need some fleece to protect your early flowers and bedding plants on frosty nights in inland gardens. 

Try to take fleece off again before it gets wet as heavy wet fleece can do more damage than not having it.

May is the month to plant:


May is peak Clematis month. From rampant Montanas to more stately Raymond Evison varieties.


Perennials and Alpines

A huge range in now. coming into flower Aquilegia (columbine), Scabious, Iberis, Aubretia, and lots more


Massive range in now. Bush, Climbers, Shrub. Patio Roses will be in later on, at the end of May.


April and May are the months to plant herbs. Plant out the hardy ones: thyme, mint etc first and leave the more tender herbs such as basil till early June.
