A very quick update - I have two flower buds on my cotton plants which look almost ready to open. I think they'll flower within the week.
Apparently the flowers only last two days, so I'll be watching closely to make sure I don't miss them.
I don't know how long it takes after the flower has dropped for the seed pod to form, but I really don't think there's enough summer left to ripen them. Anyway, we'll see - the weather for the next week is still good, and hot, but it is starting to cool down at night. It would be a shame to get this far and not get even a teensy bit of fluff!
P.S. Five minutes after publishing this post, I went to check on the buds again, et voila :-
This is the bud I photographed this morning. It's a beautiful cream colour (but no scent). And the second one isn't far behind it :-
Aren't they gorgeous? Fingers crossed that we now get enough good, warm weather to allow them to form seed pods. It's still 33 deg. C today, but that can change quickly if any bad weather does come this way.
