I only tied the main stalk to the trellis and the 2 or 3 bigger branches.
When I tied more up the branches bent and kinked up/split with the weight of the pods.
Let your plant grow for 1 year untrimmed.The end of the 2nd year trim only the smaller branches.
You'll get a more uniformed growing bush rather than a vine type plant that way.
If you trim it too early it won't bush out as much.
They also grow mostly in the fall through spring.They don't like hot weather and won't bud or fruit in 80+ degree weather.Pods tend to cook and the buds and leaves fall off.They come back once it cools off.
They like watering a lot but not wet soaking wet soil.
They LOVE 5 parts fine orchid bark , 1-2 parts Peat and 1-2 parts perlite for soil.
With a bark based soil you HAVE to give it a weak (1/10th mix) of fish emultion almost every week.The bark eats up nitrogen.
I give mine a weak mix of Iron and zink,fish emultion,seaweed extract and calcium concentrate a couple times a week during growth , budding and fruiting.
Soil mix lasts about 5 yrs. but orchid bark is expensive.
Manzanos are $10.00 LB. here so it's worth the $$$ on 5 yr. soil with the amount of pods I get and only having to re pot every 5 or so yrs.
My tree hab. lasts 7 or so yrs. in this soil mix before I had to re pot it.
Top pots off with peat every year as it shrinks when the peat breaks down.
When I repot I just mix old soil with bark and peat-the perlite doesn't break down.Use peat and bark thats as close to matching in size as you can.It will airate the soil better-screen it if you can.It works better but isn't a must do.
