Greenhouse Sales

Greenhouse Sales Closed for Summer:

After a great spring, the Thompson School Greenhouses will close for sales after Saturday, 6/20.  We will re-open for Mum, houseplant and succulent sales on Friday August 28.  Although we will not be selling plants over the summer, we will still be here, and all are welcome to stop by and see what’s going on, including our new hydroponics and aquaponics work.

We at the Thompson School Greenhouse would like to thank all of our friends and customers for a great spring, and to let you know that your support and purchases help make possible the hands-on, effective learning experience through which our students excel.

~ Tip of the Season ~

90% of the time, Durham’s typical Last Spring Frost is around May 13.  Although frost sensitive plants like New Guinea Impatiens should stay indoors until the “last frost date”, frost tolerant plants like pansies and perennials can be planted outside now.
