Burro’s Tail, known scientifically as Sedum morganianum, is a popular succulent admired for its distinctive trailing stems adorned with plump, bead-like leaves, making it a favored choice for hanging baskets. Understanding its specific temperature needs is important for maintaining its health and encouraging robust growth.
Ideal Growing Temperatures
For optimal health, Burro’s Tail thrives between 65°F and 75°F (18°C to 24°C) during the day. A slight overnight decrease to 55°F to 60°F (13°C to 16°C) mimics its natural habitat and is beneficial. Maintaining consistent temperatures within these ranges supports healthy growth and vibrant leaf coloration.
Protecting From Cold
Burro’s Tail has limited cold tolerance. While it can withstand brief exposures to 40°F (4°C), it prefers conditions above 50°F (10°C). Freezing temperatures below 32°F (0°C) are detrimental, causing irreversible damage to its fleshy leaves and stems. Prolonged chill leads to cell damage and significant stress.
To protect your plant, bring it indoors if outdoor temperatures are expected to drop below 50°F (10°C). Inside, place it away from drafty windows or doors to prevent sudden temperature shocks. Reduce watering frequency in winter, as growth slows and excess moisture in cold conditions can cause root issues.
For outdoor plants in marginally cold climates, temporary frost cloths offer some protection. However, indoor relocation is the most reliable method against frost.
Protecting From Heat
Burro’s Tail tolerates temperatures up to 100°F (38°C). However, prolonged exposure above 80°F (27°C) can induce stress, and above 90°F (32°C), damage may occur. Temperatures exceeding 109°F (43°C) can trigger dormancy and increase rot susceptibility, especially in humid conditions. Managing heat prevents sunburn and dehydration.
To mitigate intense heat, provide partial shade during the hottest parts of the day. Increasing air circulation also helps dissipate heat. While the plant needs water during hot periods to prevent dehydration, ensure adequate drainage to avoid overwatering. Moving the plant to a cooler, shadier location temporarily can provide relief during heat waves.
Signs of Temperature Stress
Changes in your Burro’s Tail indicate temperature stress. In cold conditions, leaves may become discolored, appearing translucent, brownish, or black. Cold damage often results in soft or mushy leaves due to cellular damage. Stunted growth or unusual leaf drop can also suggest the plant is too cold.
Heat stress shows different visual cues. Leaves might wilt, shrivel, or develop scorched spots from sunburn. Yellowing or browning foliage is another common symptom of excessive heat, and increased leaf drop can occur as the plant conserves moisture.
If these signs appear, move the plant to a more suitable environment. For cold-damaged plants, trim affected parts and allow soil to dry before watering. Heat-stressed plants may need careful, increased hydration.
