Tulip bulb reflorification?
My garden has about 200 tulips planted, but only about 40 in any given year produce blooms, mostly the old Darwins and Emperors, so I end up with a lot of yellows and reds (bor-ing!).
However, I have great leaf production from the non-bloomers so I know they are still alive and some of these are really fine and fancy types. I acknowledge that some are in the wrong locations (too much shade, competition from tree roots, etc.) and I understand that many varieties are really not re-bloomers.
That said, I would like to see if I can dig up the non-bloomers and give them another chance.
Is there any protocol for revitalizing or resuscitating a tulip bulb's blooming potential?
