Q: I planted asparagus two years ago. The plants are six feet tall. Do I leave this growth or trim it back?
A: The ferny foliage is vital to absorb the energy needed to make stronger roots and more spears next year. Do a fall fertilization now but leave the plants alone until frost kills the stems. Clip them at ground level in December. Control winter weeds assiduously and enjoy some fresh spears next spring!
