hey farmer.....i never lost one yet...lol....i just do not like to transplant to many times...i keep it to just 1 tansplant..as it always takes a few days for them to adjust....
roots stay white but wrap around the bottom of the cup...then i basically loosen up the soil and i get rid a lot of that soil...then i unwind some of the roots that are spun around the bottom and put them into their final resting place..
but hey..whatever method works ...
keep it green my friend
p.s. i am still learning...
