two shrubs

[mikkib]

I have two plants. One is healthy the other yellow and droopy. They are planted beside each other and get the same care. What does it need?

[thugulike]

The sick plant may have a vine weevil in the pot. Vine weevils eat the roots. Try and pull at the plant gently. If it comes away in your hand then the roots have been eaten. You must go through the soils and destroy the grubs which are white or they will spread.

Other than than maybe the drainage in that pot is different?
