    Default nubbies inside leaf

    Those little nubbies inside Catt leaves that John has mentioned a couple of times....do those mean that the leaf is not going to sheath or that it will? Or something else entirely?

    not sure what you mean...by the time the leaves open up you'll either see a sheath or you won't. occasionally a sheath will not produce flowers, especially in young plants. vice versa, once in a while you won't get a sheath but you'll end up getting a spike. again, usually in the first-bloom population. but other than those exceptions, sheath = flowers at some point, no sheath = wait til the next growth.

    What about if the sheath turns brown? Any chance of still seeing flowers?

    I have a potinara who produces spike out of sheath that are still green and brown (usually sheath produced from last year). I don't know why this happen, I thought its normal for the plant to do this .

    depending on the plant, some will bloom from green sheaths, and some will rest for a while and then bloom from dry sheaths.

    Lisa, I remove browning sheaths because they take the buds with them if it is from fungus. Just pull straight up and they come away clean leaving the buds inside intact.

    don't some catts bloom all of the time without a sheath? just the buds come right up?

    I have some that do both, but haven't paid all that much attention to regularity of either.

    Sometimes the ones here will develop buds without ever developing a sheath--but that (for me anyway) is very much more the exception rather than the rule. If a sheath starts to turn brown (not dry) before the buds have poked through, I'll pull it apart at the top and peel downwards a little to create an opening. Many times if you don't, moisture will condense on the developing buds inside and blast them. Opening the sheath lets enough air in to allow the moisture to evaporate.

    What about if the sheath turned brown and dry even if its still empty? That is what my NOID potinara is doing again. It usually do this, produce a sheath in late summer and then nothing happens. It might or might not spike in spring out of the dry sheath and from a newly produced still green sheath. Its crazy, makes me confused . Sometimes I think that maybe I am not giving it enough food?
