Q.snowberry bush – pollination/fruit-bearing
do i need two snowberry bushes in my garden in order for them to pollinate each other and bear fruit, or can one bush do it all on its own? thank you.
Since the Snowberry attracts a just about every pollinator out there (bees, hummingbirds and butterflies), there's a good chance that the flowers on a single bush will develop into fruit. If you want a 100% certainty of your shrubs bearing fruit, go ahead and get two, but space them carefully so that they get plenty of air circulation which will reduce the chance of disease.
Don't forget that all parts of this plant are poisonous if ingested, except to the birds who will eat them during the winter months.
