KNOXVILLE, Tenn. – Hydrangea is a popular shrub throughout much of the U.S., so the plant is a natural choice for nurseries to produce for wholesale markets.

In July and August, faculty from four regional universities will present a day-long workshop for nursery professionals focused on how to produce excellent hydrangeas. Hydrangeas from A to Z will feature educational sessions on potting substrates, fertilizers and bluing; pruning; propagation and breeding; disease management; and more.

An afternoon session is planned to include hands-on demonstrations with hydrangea crops. Participants will see first-hand the effect of lime and aluminum on pH and flower color. Also featured will be plant growth regulators, pruning techniques, container substrates, and comparisons of fertilizer and irrigation rates on plant growth and quality. A hands-on disease ID session and Q&A with speakers and industry representatives will allow attendees to explore issues in depth.

The workshop will be presented three times:

July 21st - McMinnville, Tennessee
August 2nd - Virginia Beach, Virginia
August 4th - Smithfield, North Carolina

The cost to attend any session is discounted to $35 for participants who register prior to May 31. The cost is $50 for those registering June 1 - July 15 for the Tennessee workshop and $50 for those registering June 1 - July 28 for the Virginia and North Carolina events. Registration for each event will close after the prescribed deadline. Space is limited and no on-site registration will be available.
