It is not a frost-hardy plant and unlikely to survive in temperatures below 30 degrees Fahrenheit. However, it will grow back once spring rolls back around.

Watering and Feeding

Autumn Joy has low water requirements. Once established it is drought tolerant due to its ability to store water in its thick leaves.

Water plants more if planted in full sun during unusually hot weather.

The plant will do well with regular watering when the soil begins to dry out. Make sure not to overwater Autumn Joy plants.

For fertilizing, stay clear of high-nitrogen varieties as the nitrogen helps plants produce weak growth.

The best choice is to add a layer of compost on an annual basis.

Soil & Transplanting

Well-drained soil is essential for a healthy Sedum. It cannot survive in waterlogged, heavy soil.

Rich soil is also a no-go as it causes plants to have flopping stems and weaker growth.

Transplant Autumn Joy in spring as soon as you see new growth appearing.

This will give the roots a chance to settle in before the extreme heat of summer arrives.

Grooming and Maintenance

Prune plants in the fall or early spring to keep them short.

How to Propagate Hylotelephiumdum Autumn Joy

Propagate sedums through division or stem cuttings.

When using division to propagate Autumn Joy, take care to do it on a day when it’s not too hot.

Dig around the perimeter of the plant until the plants lift easily out of the soil (no heavy pulling).

Divide plants gently using your hands or by cutting it with a knife.

Plant the new division in its decided location and make sure to keep the soil moist until the plant takes root.

If propagating using cuttings, take cuttings from newer growth as opposed to older mature stems which root much slower.

The best time to take cuttings is during their growing season either early in the morning or late afternoon.

Cut about 2″ to 6″ inches and remove the leaves along the stalk.

Place them in a plastic bag along with a slightly damp paper towel to keep the cuttings from drying out before planting.

Plant the cutting in a well-draining cactus soil mix and wait for roots to form.
