2025-06-28 09:00 - 12:00
Speaker Matthias Meilland, Sixth Generation Rose Breeder, House of Meilland
Join us for a webinar presentation by Matthias Meilland, Sixth Generation Rose Breeder, House of Meilland! Since 1935, the House of Meilland has tested its varieties on both sides of the Atlantic. When Robert Pyle came to see the young Francis Meilland in France, in 1933, he told him to learn English and go see his varieties abroad. Francis did and traveled to the US in 1935. Since this era, the Meilland breeding team has traveled the world to see how their new seedlings were performing in different climate and soil conditions. These 90 years of data from Pennsylvania, California, Spain, Germany and France, produced varieties such as ‘Peace’, ‘Bonica’, ‘Eden Rose’ and ‘Papa Meilland’ and also incredible performers such as the ‘Drift ‘roses and many of the mid-western performing Hybrid Teas that embellish your gardens.
We will dive into the selection program, see the winners and losers and we might even take a peek into the future of roses!

Rethinking Late Summer & Fall Rose Health Strategies
2025-08-23 09:00 - 11:00 | ARS Webinar
Speaker: Dr. Mark Windham, Professor Emeritus of Plant Pathology, The University of Tennessee Institute of Agriculture

Join us as Dr. Mark Windham shows us the way to encourage a healthy spring garden starts with actions in late summer and fall. As the days get shorter, rose foliage becomes less effective in converting energy to sugars. Leaves become nutrient sinks (use more nutrients than they produce via photosynthesis). Rose roots have become saturated with starch leading to a change in the rose’s physiology which triggers the slow transition toward dormancy. At this time, plants become more susceptible to many diseases that can overwinter on canes or in debris on the soil surface.
In this seminar, we will look at ways to maintain healthy roses as they begin the dormancy transition. Proper planning and direct actions in the fall will pay dividends for healthy roses the following spring. The seminar will look at cultural ways to successfully maintain rose health in both spray and no-spray gardens.
