I planted 10 -5 ft tall techny arborvitae May of 2016 in my zone 5 backyard in a full sun location. My seemingly struggling shrubs have coned and seeded wildly this year. The shrubs are virtually weighted down by this massive production. Are my shrubs dying and showing a last ditch effort to maintain the species? ☹️

Check water requirements.
Are you deep watering them, at dripline ?
I also belive they like to be watered a few times in winter.
A little fertilizer wont hurt.
Then late fall, to early spring. Shape them up with hedge trimmers. They will love you for it ! 😁😁😁

Thanks for your input. I do have soaker hoses set up around each shrub (and water when we don't get an inch a week). Our soil is heavy clay and the rainfall around here has been off the charts so I have not been irrigating much because I don't want to drown them I used a cup of milorganite around each bush in early spring. Have you ever experienced this heavy budding with almost no leaf growth? I have until May 10th to figure this out in case of have to pull 500 dollars worth of trees to get a refund. So confusedπŸ€”

May 10th. Lots of time.
Your weather mild ? You could trim now maybe ?

They do usually alternate bloom.

More info given ! Good 😁

Clay soil 😬 ! Not good.
You need to work some compost or wood chips into soil. Say ! 8 to 12 inches deep, for drainage. Do this from drip line, to 3 or 4 feet out.
If wood chips, mix in some fertilizer.

After that, I'd top dress, with 3 or 4 inches of either. Then every year with 3 or 4 inches of wood chips. Clay wiil decompose chips in year. You'll have some nice soil for flowers around trees. 😁 Thumbs up

1-Inch water per week. Good for vege garden. Not trees. Trees need deep watering. So roots can grow deep.
One inch of water. Generally, penatrates one foot deep.

The transplanting did have a factor in the massive cone production, but your trees are good and healthy. The "myth" that overproduction of seeds is a sign of ensuing death is only true for some plants (in fact, very few in the big scheme of things). It is not uncommon for trees in general (including arborvitae) to go through cycles of heavy fruiting and light fruiting. Next year, all those little cones will be brown, and from a distance the trees won't look so great because of that. But close inspection should still reveal good green healthy leaves, as it does now. Your trees will just grow out of it.

Sometimes plants grow differently in California (for instance) than they do in Wisconsin or Minnesota. Arborvitae do well in clay soils here. Your present watering practice is just fine. But if you want to start weening them off of additional watering, you could do that, too. You can trim if you want, but it is not needed. Here in the north, best to do it before September if you are going to do it.
