I had posted a query on some trouble I had with Arums and leaf curl and die back. Nathan suggested a non ammonium fertilizer which I did. I've attached a picture of one of them that flowered for the first time in a couple of years. I used Schultz's 8-14-9 Nitrogen analysis: 0.7 % Ammonium nitrogen0.4 % nitrate nitrogen6.9 % urea nitrogen It worked out much better although towards the end of the season I'm seeing some of the same conditions with one plant. Here is a flower on the A. korolkowii I think if I repot in all fresh soil it will be better next year. Arnold -------------- next part -------------- A non-text attachment was scrubbed...
