Had landscaping company put these in a year ago, added irrigation 3 months ago, still can't figure why 3 are green all the others yellow. Is it the clay dirt or soil type, lack of fertilizer?

You should do a soil test to see if anything is lacking in nutrients, or possibly too much or not enough PH for those plants to thrive.

Wouldnt rule out too much water if this is a recent development after adding irrigation and all the rain we have had.

I have a ton of boxwoods and they can be funny. some die for no reason, some partially die for no reason. some may get too much water and die. Some thrive even though they sit right next to a dying one. wish I knew.

Were they green when you planted them? Almost looks like sunshine ligustrums.

They were all green when planted, only 3, all next to each other, stayed green. Maybe the soil there was different. Thought about using fertilizer spikes to see what happens. Did have a few just die, looks like a blight or disease.

Do a soil test first before you fertilize them further. They’re cheap and your get your results back quick

It’s related to drainage. Boxwoods don’t like to stay damp. It is a soil thing/planting depth thing and complicated by the irrigation

You can elevate the boxwoods that are doing bad to help but I would dig a trench along the base of the boxwoods that are doing bad to the drainage pipe and backfill with road gravel to allow them to dry out

Cut a stem and see if there’s any black wood in the cross-section. If so you have boxwood dieback. It usually only takes a whole branch, not the whole bush like your photo, but a lot of nurseries missed this pathogen the last couple of years and it could have infected your entire plant.

Mine are way more mature than yours, but I noticed after our hard freezes this winter that all of them looked yellow-ish like that, but the leaves looked healthy. They're almost fully transitioned back to green now though.

But I'd say if the leaves look healthy on your yellow ones, could be a possibility?

Were those 3 green ones yellow prior to the irrigation being added? Or were green all along?

I do have 2 that look dead, just sticks branches and very few leaves(out of sight on other side of sidewalk), and will replaced, seems like they never looked strong from the start.
The drainage was put in with the plants( 3 green ones) because that section had no way to drain except over sidewalk and i wanted to give water a way to flow under sidewalk. That cant be coincidence that where the French drain with gravel is located is the same spot the only "healthy plants are". Just didn't know these plants required good drainage.

The dead ones are in a corner that holds water

Plus they are being crowded. Id dig the ones up by the steps cause ya have other plants rite next to them.

Dwarf youpon hollies are a good alternative to box woods. You can plant close together as a hedge or space them. They grow in a natural ball shape with a little pruning now and then to shape them. They seem impervious to heat, freezes, and water issues in my experience.

Guess soil testing is easiest thing to begin, and then go from there. Thx for all the replies and suggestions. Youpine looks like a good choice too
