Our mason bees have mostly emerged and unfortunately our rooftop is almost devoid of flowers. With the exception of a large rosemary plant, and some heather there is very little to keep the bees around right now. At ground level the cherry blossoms are out, so hopefully that vertical distance isn’t too much to prevent them from returning over the next little while.
On the upside, our berry bushes are showing leaves and FAR more flower buds than we saw over the past two years. Red currants, black currants, gooseberries and blueberries have started flowering over the past week and while the flowers aren’t the bright pinks and reds of some other plants, it looks like they’ll be available in abundance. If we’re lucky there are still enough mason bees around to pollinate them as we have yet to see any volume of honey bees or bumblebees.
Here’s hoping that the combination of warmer weather and more abundant berry blossoms will do the trick.
What’s the problem with pollinators? There aren’t enough of them… and they sleep in.
My second year, I added berry bushes to the roof, and added to the count this past season. What I found is that the berries bud and flower much sooner than vegetables in this climate, and apparently much sooner than bumblebees and honeybees surface to help with pollination. As a result, I’ve had very limited fruit production, though this past year I was able to get some improvement by manually making the effort.
I don’t know if the issue is that local pollinators aren’t emerging at the same time, or whether the location, and relatively limited flower options means they don’t visit until blooms are more abundant. Regardless, it’s a problem that I’m trying to deal with on a couple levels in 2019.
First, I scattered wildflower seeds in some beds reserved for non-edibles in hopes that they will emerge and flower to provide additional options for any pollinators that do emerge and visit early in the year.
Second, I’ve purchased a number of solitary bee homes and will be seeding them with mason bees in March, in hopes that the early-emerging mason bees will bridge the time between early flower emergence and the arrival of the pollinators that service the broader pool of fruit and vegetable plants.
If anyone has other ideas I’m all ears, as I’d like nothing more than to have bushes loaded with berries through the spring/summer of 2019.
