Worcester Cty. Evergreens in pots
I want to grow some evergreens, including hollies, in pots on my deck in 4-6 hrs. of sun. What do you suggest? Thank you
You did not mention the size of the containers and mature height and width of the plants. Use as large containers as you can. Keep the plants well watered until the soil freezes.
To overwinter woody plants outdoors - Plants in containers need to be 2 zones hardier than your zone. You may be able to place the container next to your house and cover with pine boughs or shredded leaves for winter protection. Or even better sink the container in the ground to protect the root zone from the cold temperatures.
Here is a link from Chicago Botanic Garden on Overwintering Evergreens in Containers https://www.chicagobotanic.org/plantinfo/faq/overwintering_evergreens_containers
Here are some suggestions:
Dwarf Hinoki falsecypress (Chamaecyparis sp.)
Dwarf Arborvitae (Thuja sp.)
Dwarf hollies (such as Burford holly)
Osmanthus heterophyllus 'Goshiki'
It may be helpful to visit some nurseries and large garden centers for more ideas.
