Hi Russ,
If it is any consolation, you have company here in the failure department. Yep….. “been there done that”, also! Looks like I started later than you, didn’t get my first cuttings out of the moss until end of February but, experienced the same joy followed by the dismay of failure you have.
Thought I was doing everything right, about 100% cups full of root and lots of leaves. Then roots started taking on a brownish color. That should have been my first clue things were going south. Like you, think maybe I over mothered my babies, too little water, then too much, even had them on seeding heat pads for a while. Way late in the game I realized I had rot issue, most likely caused by the “fine “perlite”, which had turned to a soggy mush at the cup bottoms. About the same time, Jon posted his thoughts and remedy for this same malady. Also, in hindsight, thinking maybe left the babies in cups too long.
Yes, a real learning experience for my first time. Here’s what I am doing different, 1- Way more cup aeration, more/larger holes in cups. 2- Found a local source for larger perlite and using it liberally. This will surely help eliminate the overwater possibility. 3- Think too, I will move cups up to one gallon sooner, not so compact, let those roots run. 4-Be a little more discriminating as to size of cuttings I root. Short fat ones seem to have a lot more energy and hardier. Tall skinny ones are fragile, dry out easily unless you have a greenhouse and I don’t.
Also, at least for the survivors, they are going outdoors at first chance. I hung up a partial (50%) sunscreen on protected north side of house so; they get filtered sun part of the day. They seem like it there, just by looking at leaves. Figure I will move around the south side for more sun as they acclimate. BTW…… our nights run 55-60 and days70-75 range, plus variable humidity of 50-75%.
Best of luck Russ
