Du Comice (Royal Riveira) Pear Trees
I planted this pear tree (Du Comice - or Royal Riveira) about 8 years ago, and it has grown wonderfully. It is about 10-12 feet tall and looks great, but it has never produced any blossoms. I was just wondering if there was something that I could do to encourage it. I have put in fruit tree fertilizer stakes from time to time - but nothing happens. does this type of tree need some special nutrients or fertilizer? Just wondering Paul Harder

I don't think your problem is related to a lack of nutrients. In fact, too much fertilizer could be part of the problem. Nitrogen promotes vegetative leaf growth, not flower production. So I would hold off on fertilizer your tree anymore for a couple years.

Temperatures fluctuations in late winter can cause flower buds to lose cold hardiness, and result in buds dying before they have a chance to bloom. Or if trees are fertilized in fall, before leaf drop, winter hardening off could be delayed and result in flower bud death.
These are just a couple possibilities.
