A quick search suggests many possible causes as you mention. You could take a photo or a cut branch to garden centre and see if they could help diagnose water vs nutrients. Planters are harder to keep adequately watered especially in hot weather. Often a flood followed by a drought over and over again especially if the plants are big and have filled up the soil with roots. I think that would be hard on the roots over time. Or water runs out of planters too fast.. saucer could slow that down. If you have a very tall planter and the soil is too deep and the water in the soil is so low that it is below the roots. Saucer may help with that. I fixed that once by jerry rigging a reservoir for water in the bottom part of the pot and a wick to make the pot self watering. Less flood/drought and more consistent watering. Room for a few gallons of water down there. Or install some drip irrigation so steadier slower water supply.

Thank you for this info Beryl. I am trying to find a deep root moisture meter from a professional supply house.
Seems I either over – water or under water.
There are 3 6Ft shrubs in planter 3Ft height x 8 Ft long.
We have a drip system and the fellow said to water until the drain hose drips. — Who knows!
Does anyone know who I can call to give me some info on Emerald Cedar shrubs in a deck planter.
Too much water, too little water or root rot!
Mine are developing yellow tips.
Is there an Arborist I can contact?
Thank you!!
