I'm in zone 5 sunny Colorado at 8,000' with less than 10" precipitation a year. I purchased 6 sea berry bushes, all in 1 gallon pots. They did not come with any planting instructions. How much sun, how much water will they need. How deep and wide should I dig the holes? Are they super beautiful and should I plant where I can view them all the time or better as a hedge of some sort? The soil is sandy - what kind of amendments does it need? Mulch and if so what kind and how much? What size height and planting distance should I expect? Thank you!
The usual 3ft wide by 2ft deep should be okay.
Due to your limited rain, I would plant in depressions vs 'hills'.
Plants like 1ft of water per week, so you will have to water that much, mulch to cut down on evaporation.
Add biochar or really any carbon to cut down on water needs of the plants.
Seaberry is rat3d for zone 3 - 8 so your zone 5 is okay.
I have some and I have been eating for 2 weeks now.
Also I now have a ton of babies, they also fix nitrogen
