When do I plant:
1.) Bearberry: 1 quart shrub I got by mailorder
2.) Beach Pea Seedlings grown from seed
3.) Eastern Red Ceder Seedlings
I'm planning on planting them at my parents when I visit for Easter (March 30) or Mother's Day (May 12).
the bearberry and eastern red cedar are tough, march is fine. just make sure you acclimate the plants to full on outdoor exposure over a couple of weeks (gradually giving more and more exposure) before planting for best chances of success.
don't know the other plant so can't say.
