Answer: Raspberries renew themselves by sending out new shoots from the crown of the plant so if you want to contain their growth you'll either want to plant them in a raised bed or you'll want to lay a barrier around the perimeter of the planting so they won't overtake your yard. Raspberry roots send out shoots which become the current year's cane. After they flower and fruit you can cut off that part of the cane and the remaining part of the cane will produce more flowers and fruit later in the season. Then it will die. The roots will then send out new shoots which will become the current year's canes and begin the flowering and fruiting process all over again. If you do not thin out the new shoots you'll eventually have a thicket of old and new canes and you'll also find shoots emerging from the roots quite a distance away from the main crown of the plant. If you garden on a regular basis you can keep raspberries under control. But if you garden only occasionally you may find that they've run amok while your back was turned. However you decide to contain your exhuberant raspberry plants, you're sure to enjoy their very tasty berries.
