If a plant keeps getting scale that's probably an indication that the
plant is weak or not in good condition.

Apparently, yes. Healthy plants are able to fight off most of the
organisms and microorganisms that would like to make a meal of some
part of that plant, and to do this a healthy plant uses chemical or
physical methods. It is when the plant is stressed or in poor
condition that opportunistic invaders are able to get a foothold and
overwhelm the plant's defences.
