Step 3: Planning and Spacing
Planning is one of the most important parts for anyone who wants to start their garden, and yet it’s one of the most common things for novice and first-time gardeners to overlook when they plant something. If you want to do it right the first time and avoid any unnecessary transplantation of your plants later on, do some basic planning before you start planting anything – even just a rough scribble of your garden on a piece of paper is enough to start the planning process.
Many varieties of blackberry plant out there will prefer to trail along a trellis for their later growth stages, and they’re pretty adaptable and can be woven through the trellis as they grow.
Other varieties of blackberry plant (mostly the non-trailing varieties mentioned at the beginning of this article) will instead form a bushier, stockier plant.
Spacing is essential, and for blackberries you should space them at least four to six feet apart for larger varieties, and at least six to eight for the larger, trailing types.
