Bee-sy!
I love watching bees swarm the stonecrops on nice sunny afternoons. If a garden is thriving, the bees will come to visit, but if you want to entice them further, here are a few pointers.
Avoid using insecticides, pesticides or harsh fertilizers.
Bees like tiny flowers that make it easier for them to collect pollen and nectar, so plant as many of the following as possible to attract them: sedums, catmints, beebalm, lemon balm, goldenrod, lavender, butterfly bush, mint, basil, thyme, rosemary and verbena.
If you can, provide a source of fresh water.
Choose native and heirloom species, they constitute better sources of pollen, which is bred out of the hybrid varieties in the process of hybridization.
Have flowers in bloom for all the seasons. Plant herbs, they love herbs. Make rooms for flowering trees.
Allow the garden to grow a little wild to make the bees feel more at home and provide them with shelter.
