Stonecrop Pests or Disease Problems

When growing outdoors, plants may have problems with slugs and snails. Prevent slugs and snails by:

  • Picking off these individual pests
  • Working the ground around the plant regularly
  • Using slug and snail bait
  • Introducing nematodes to the soil to help control the pests

Excessive watering may cause bacteria and fungus to grow.

Fungus, in turn, may cause damaged roots, and withering and discoloration of shoots and leaves. Reduce watering and provide well-draining soil.

Aphids, mealy bugs and/or scale insects may also be a problem in an outdoor or indoor setting.

Outdoors aphids, mealybugs and scale insects are best dealt with them by encouraging natural predators such as parasitic wasps, ladybugs and the like.

Indoors, these pests may be washed off with a strong spray of water and/or scraped off. Discourage them with occasional treatments of neem oil and water.

Outdoors vine weevils may also be problematic. Remove them by handpicking, treating with a neem oil solution and introducing nematodes to the soil.

Even so, very young, tender leaves can be safely eaten without cooking. Slightly older leaves can be safely eaten when lightly sautéed or steamed.
