My guarana just started flowering
To revise my earlier posts from last year now i have experience growing it, I planted it in 6.0ph soil and it grew slow at first but then just took off, I fertilize it with happy frog acid lovers just to give it that little lower PH. Its planted where it receives full sun most the day with periods of shade from taller trees throughout. I don't water it, its fine between rain cycles. Its seen down to 40F with hardly any signs of stress, so as they get older just like any tropical plant it can tolerate more cold. So this is my observations, also nothing bothers it, so its a tough easy plant to grow.
Here's a picture of mine taking off, i planted it in march as a few foot long bush wrapped around a wooden trellis, now its extending over 10 feet and rapidly growing. its more of a vine than bush but if it doesn't have anything to grow on it just climbs on itself forming a sort of bush.
I am still unsure if you can eat it raw, also does anyone know if the red pulp around the seed can be eaten or has any use?
