I have a 10 year old well established Sago that has not produced all year. There are no signs of fungus. I have five others that are doing fine. Suggestions?
Sago Not Producing
If the plant is getting everything identical to the others, (including it's container) it should be fine. Are you giving it adequate and appropriate fertilizer?
And this might sound strange, BUT, when I can't find a reason for a particular plant not growing as it should, I threaten it. Yes, it sounds a little weird, but it has worked.
