Since bonds are always reaching their promised payout terms upon their maturity, you can manage that risk through proper alignment in maturity dates.
You can purchase multiple bonds that are spread around their term duration. E.g. buy now 1-year bonds, and repeat every 3 months. After 4 such cycles, you will now always have bonds reaching maturity every 3 months.
Or just buy shorter term ones to begin with (if the interest is still appealing), and move to longer term ones once you have enough maturity diversity for the advice in the previous paragraph.
