  Yellow spots on Amorpho. alba

Dear Jakub,

A friend alerted me to what, in retrospect, is probably your
problem---spider mites! Examine CLOSELY the undersides of the leaves w/ a
magnifying glass for TINY, almost microscopic living beings (mites, which
are Arachnids), as the yellow spots on upper sides of the leaves are
distinctive of the damage done BELOW the leaves by these feeding pests!

The mites infestation wasn't as big as on nearby T. venosum, but there
were few of them on this Am. albus too. But that was before I sprayed
them with acaricide. I'll try to find some shady spot for the plant and
water it more often.
Thank you for all your answers.

Hi Jakub,

An easy way to diagnose for mites is to hold a clean white
handkerchief or piece of paper under a potentially infested leaf and
flick the leaf gently with your fingertip. If you subsequently see
tiny specks moving on the white field then you know you have a problem.

Best,
Bryan
