Step 4: When to Plant
Planting something new isn’t nearly as hard as beginning gardeners might imagine, and getting a blackberry plant to thrive is much easier than you might have thought at first. Once you have spacing and soil conditions right, you’ll have to think about when to place your plants in the ground – and this is one factor that can and will vary greatly depending on which climate you find yourself in.
For blackberries (and most other types of berries) you want to plant them nearing fall, and sometimes for colder climates spring can be best for the initial planting phase.
If there’s one thing that blackberry plants don’t like, it’s frost and cold – and planting at the right time ensures that your plants are able to stand up against the cold when it hits. Plant at the wrong time and it can take just one frosty morning to undo weeks worth of planting process, so make sure that you do it right.
