From L-R clockwise: Hairy-footed flower bees on Comfrey; wallflowers in rooftop planters; primroses for short-tongued bees; lungworth (pulmonaria) for long-tongued bees
If, like me, you didn’t get round to March tasks because of the rain, don’t worry, do them at the beginning of April instead. At least the dandelions, alkanet and other ‘weeds’ for bees will have grown well with all that rain followed by early April sunshine. Here’s a recap of the tasks to do.
Gardening for bumblebees:
- Leave a patch of the garden wild for nesting sites and don’t disturb a nesting site if you find one in a compost bin, under a shed, or even in a watering can (it will only last until the end of the summer).
- Put up a box for blue tits. After the chicks have fledged, the box may be inhabited by tree bumblebees. The colony will vacant at the end of summer, so the blue tits can use it again next spring.
- Plant dead-nettles, primroses, forget- me-nots, and rosemary to provide food this month for short-tongued bumblebees.
- Leave ‘weeds’ like dandelions and alkanet to grow. They provide much-needed pollen and nectar in early spring. And you’ll see lots of different bees coming to feed on a clump of alkanet.
- Sow seeds inside now to create more flowers later in the summer. Sweet peas, sunflowers, cosmos and Anise hyssop are some of the easiest to grow in pots. Try growing on a heated mat until the seeds germinate. I’m also going to try chives, viper’s bugloss and cornflowers outside.
- Don’t mow the lawn to let clovers flower.
- Ditch the weed killers, like Round-up, and any pesticides and bug sprays you may be using on your roses, or any other plants.
Gardening for solitary bees:
- Plant lungwort, wallflowers, early-flowering comfrey and flowering currants (Ribes) for long-tongued hairy footed flower bees. Red mason bees and mining bees, with shorter tongues prefer flowering fruit trees, willows, spurges, alkanet and forget-me-nots, and mining bees.
- Leave old mortar untouched as hairy-footed flower bees may be nesting here.
- Make cob bricks with holes in that hairy-footed flower bees could nest in instead.
- Install bee-hotels in a warm location at least a metre off the ground, where red mason bees (Osmia bicornis) can check-in and lay their eggs. We like to use these type of bee hotels with the cardboard tubes. You can take the cocoons out of in the winter and clean them. Leafcutter bees may use the hotels during the summer.
- Install a bee observation box which many different solitary bees may nest in over the season, including large-headed resin bees (Heriades truncorum) , common yellow-faced bees (Hyleaus communis), and blue mason bee (Osmia caerulescens) . The box comes with a removal panel which allows you to observe the life cycle of the bees.
- Leave a patch of bare earth for mining bees to burrow and nest, and where red mason bees can collect soil to plug their nests.
- Leave a pile of tiny pieces of grit that resin bees may use to plug their nests.
Bees to See in March
Here are tips for identifying the different species bees you will hopefully see in March in your garden, patio pots or window boxes if they are planted and maintained for bees.
