When I did the plants at Lowe's ( I worked for Metrolina the nursery ..and merchandised the plants at 3 Lowe's) each store had a different approach to markdowns...one store would often mark entire carts just unloaded from the truck half price. The orchids all got marked down after a week..If they didn't sell for 50% in that second week they went in the trash. Another store waited for everything to be dead before they marked it down...
sometimes I would suggest markdowns...and sometimes they would listen. Here in Tampa anyway, it seems to be the same story...but I don't see too many orchids getting marked down!
I have just started with Vanda's and am looking forward to repeat blooms!
