Pollinators for Amelanchier

a_s_hermann

I have bought 2 Amelanchier lamackii 'Rainbow Pillar' last year, which I put in containers on my first floor balcony. They flowered beautifully this spring, but I didn't see a single animal anywhere near them at any time and therefore there's not a single berry.
I have salvia on the balcony as well and there's bees up there now, so it doesn't seem out of reach for insects.
Does anyone know what the problem might be and what I could do about it? It was rather cold this spring, but we did have a few sunny days with insects out...

It could have been because pollinators are declining.. and, at least for my June berry, it was flowering the same time as the fruit trees.. so there was probably plenty of other 'easier' food for them then.  

Next year try to hand pollinate, using a soft paint or makeup brush.

Some different plants to extend the period of the year when there is some flowers there might also help. Primroses and viburnum tinus for example are good for flowering in the not so warm months of the year and the more months there is something for the pollinators to visit the more likely they will be to call by.
