Gardening and Horticulture - European Pear Never Flowers

Hi, this is my first visit and post. I planted a Semi-Dwarf Buerre Superfin Euro Pear 7 years ago. It has always been healthy with no signs of any disease or insect problems. However, it is now 7 years in the ground and 10-12 feet tall, but has never had a single flower, let alone pears. Any ideas on what might be wrong or what I could do to kick start this tree into production ???

Beurre Bosc Pear Dwarf requires another tree for pollination. Pollinate with Bartlett or Starking Delicious. www.starkbros.com (http://www.starkbros.com)

If you live where you get late cold snaps, then buds can be frost bitten and there will be no blooms. Pears bloom early, a few weeks before apples. Are there budding forming toward the end of the growing season?

Dwarf trees are 6-8' and take 2-3 years to bear fruit. Semi-dwarf are 12-15' and take 3-5 years. Standards reach 20-25' and take 5-6 years. The times stated for pears to mature enough to become productive are average times. It can take longer. http://www.richfarmgarden.com/pear.html

Thanks for the info. I do have a Moonglow Pear, plus two Oriental Pears and 3 Bradford pears all clustered together. ALL of them bloom and bear fruit except the one tree I described. I have never seen any flower buds on the Superfin tree.
