Tim, My first year I didn't use it on the semps and they were definitely less advanced. I don't do a control group because I want them ALL to grow. The time for comments is WIDE OPEN Tim.
LOVE the historical photo! I think Lynn is about to sing "I believe in Quick Start". BTW there are LOTS of transplanting type fertilizers. I got tuned into Quick Start by an iris grower in St. Louis as it allowed him to get 100% first year bloom on iris seedlings. It works on all my seedling crops.
