The species was described back in 1753 by Carl Linnaeus as ' Euphorbia tithymaloides'. Remove some of the affected leaves and increase waters slightly. If yours has fallen short of this, reduce the amount of the sun considerably and always be mindful of environmental shock (when two locations offer too different growing conditions). Although too little light will cause over-watering issues, excess sunlight will be a detriment to the plant as well. Too much sunlight will lead to sun scorch, with typical signs including browning or crispy leaves, dry leaf-edges, sunken leaves or stunted growth. Finally, always remove yellowed or rotten debris from the soil as it could harbour both bacterial and fungal diseases which will continue the plant's decline. Take stem cuttings to promote a bushier appearance above the soil line - scroll down to 'Propagation' for more information. For specimens that have a bare head, improve growing conditions by using this method and increasing the light levels and air circulation. Although watering from the top is best, it's recommended to use the bottom-up method if you're a messy waterer. More information about addressing root rot can be found on this link.Ī lack of leaves on the soil's face could be the product of excess moisture settling on the foliage. If the roots sport a yellow tinge, you're good to go, but if they're brown and mushy, action must be taken immediately. Take the plant out of the pot and inspect health below the compost line. Symptoms include yellow or rotten leaves, mouldy soil, stunted growth and a rotten base resting against the soil. Root or leaf rot is a common issue among specimens sat in too dark environments with prolonged soil moisture. Never apply a 'Ready to Use’ product into the soil without a pre-water first, as it may burn the roots and lead to yellowed leaves. Never situate it within a few metres of an operating radiator due to the enriched chance of crisping foliage.įeed every four waters during the growing period and every six in the autumn and winter, using a 'Houseplant' or 'Cactus' labelled fertiliser. It's always better to under-water Devil's Backbones than over-do it, so if you're unsure as to when it needs a drink, leave it for another few days!Īverage room humidity is more than enough to satisfy this plant. To confirm that your specimen needs a water, feel the weight of the pot and if it still feels heavy, allow the pot to become slightly lighter before another hydration. Those kept in the traditional pots must have the soil's top half to dry in between waters. Bright, indirect location is still advised however, you must keep on the drier side to avoid over-watering from its moisture-retentive leaves. We'd recommend a windowsill, or a nearby table is the perfect location for this plant, as a lack of natural light penetrating the compost's face may result in root rot and soil mould. Specimens kept on a shelf where the soil line isn't in view of the natural light must follow the rule of 'near-drenches between droughts'. Ī minimal amount of morning or evening sunlight is fantastic for Devil's Backbones.
