According to Better Homes & Gardens, the optimal time to cut back on Morning Glories is in the fall after the first frost has caused the plants' foliage to dry up and die.

For the best results, cut the foliage about two inches above the ground with pruning shears. Use a measuring tape or yardstick to ensure you don't cut the foliage too short.

Suppose you are concerned that the roots do not have enough protection from weathering the coming cold months of winter.

How To Mulch Around Morning Glories

The Farmer's Almanac advised pulling weeds before mulching.

Without removing the weeds before adding the mulch, those weeds will grow through the mulch and consume nutrients from the soil that the flowers could absorb instead.

Word of caution: don't use more mulch than necessary or have it uneven with areas of more than four inches in any area because over-mulching will diminish the oxygen supply to the plant's roots.

Also, over-mulching will encourage fungi mats to flourish. Those fungi mats will repel the water you want to conserve for your flowers' root systems.

Safety Considerations When Growing Morning Glories
