Ishmael Fleishman Posted April 26, 2023 What is the likely cause of this yellowing along the line of the Areole in this San Pedro - is it variegation or lack of nitrogen or other? Share this post Link to post Share on other sites
Strontium Dawg Posted April 26, 2023 Could be that it's getting strong light somewhere it's not used to, and/or needs nitrogen. Give it a feed of some of your urine every day for a week, and make sure to give plenty of water also, cos salt buildup Share this post Link to post Share on other sites
Ishmael Fleishman Posted April 26, 2023 It is basically winter now and it is a fresh cutting been given to me by a friend and has no roots. Will feeding it nitrogen now really help or will it just remain yellow until it gets some roots of its own. Share this post Link to post Share on other sites
SayN Posted April 27, 2023 Lol - no roots. Useful info to know. That's likely your problem right there. If it was me i'd probably cut the tip a bit higher up, let that callous over winter and replant in fairly inert soil closer to Spring. Share this post Link to post Share on other sites
