I just bought a few miniature conifers and want to know when is the best time to plant them.
I'm from Portland Oregon.
Now is a good time to plant. Winter is your rainy season, right? This gives the tree a chance to establish roots before the dry season next summer. It is vital when planting trees to put them in at the right depth. Even though you purchased them, don't assume they are properly situated. Google "show me your flare". If these are in containers, water well a day ahead; try to straighten roots. Some experts recommend hosing off the soil so you get a real good look at the roots. It is better to prune a root than to leave an encircling root intact. There are online videos from universities on how to plant trees.
