Snake plants, often referred to as Sansevieria or mother-in-law’s tongue, are known for their resilience and ease of care. However, encountering a snake plant with no roots can be a puzzling situation. This article provides guidance on diagnosing the issue, propagating new roots, and ensuring the plant’s long-term health.
Why Your Snake Plant Lacks Roots
Overwatering is the most frequent culprit for snake plants losing roots. Consistently wet soil deprives roots of oxygen, creating an environment for fungal infections and bacteria, leading to root rot. Symptoms of root rot include soft, mushy, or black roots, a foul soil smell, and soft or mushy leaves.
Improper propagation techniques can also prevent root development in new cuttings. Planting a cutting without allowing it to callous, or using a too-wet rooting medium, can cause rot before roots form. Transplant shock or recent repotting can also temporarily hinder root development as the plant adjusts to its new environment. Less commonly, pests or diseases can sometimes affect root health.
Propagating New Snake Plant Roots
New roots can be propagated from a healthy snake plant cutting using water or soil methods. Prepare a cutting by snipping a healthy leaf from the mother plant near the soil line with clean, sharp scissors or shears. Cut the leaf into 3 to 4-inch sections, noting the correct end for planting. Allow cut ends to air dry and callous for one to two days before planting to prevent rot.
For water propagation, submerge the calloused end of the cutting about one inch deep in a glass jar with clean water. Place the jar in bright, indirect sunlight and change the water every three to five days to prevent bacterial growth. Roots typically appear within three to six weeks, with new plantlets (pups) forming in two to three months. When roots reach about 1 to 2 inches long, the cutting is ready for transfer to soil.
For soil propagation, plant the calloused cutting about 1 to 2 inches deep into a well-draining soil mix, such as a cactus or succulent blend. Ensure the correct end faces down, and water lightly, keeping the soil barely moist but not soggy. Place the pot in bright, indirect light, avoiding direct sun exposure. Roots usually form within four to six weeks, with pups developing in two to three months. Soil propagation may lead to sturdier plants with less transplant shock compared to water-rooted cuttings.
Reviving a Rootless Established Snake Plant
To revive an established snake plant that has lost its roots, often due to root rot, inspect and prepare it. Gently unpot the plant and remove any remaining soil to expose the rhizome and root system. Healthy roots are typically firm and range from light orange to white, while rotted roots appear dark brown or black and feel mushy.
Trim away all soft, mushy, or discolored parts of the roots and rhizome with sterile scissors or a sharp knife until only firm, healthy tissue remains. After trimming, allow the plant to air dry for one to two days to callous over. This callousing step is important for preventing further rot when re-rooting. Once calloused, re-root the healthy remaining sections using water or soil propagation methods.
Addressing Common Rooting Problems
Several common issues can arise during the rooting process. If cuttings show no root growth, it may indicate insufficient light or cold temperatures. Snake plants prefer warm environments, ideally between 70°F and 90°F, and benefit from bright, indirect light to encourage root development. Patience is important, as root growth can take one to four months.
Rotting is a frequent concern during propagation, especially in water. This often occurs due to overwatering, improper callousing, or infrequent water changes. Ensure the cutting is fully calloused before placing it in water or soil, change water every few days, and avoid overly wet soil to prevent rot. If leaves turn yellow or brown during rooting, it could signal issues like too much sun, overwatering, or nutrient deficiency once roots are established. Adjusting light exposure, allowing soil to dry more between waterings, or applying a diluted fertilizer to rooted plants can help.
Caring for Your Rooted Snake Plant
Once new roots have developed, ongoing care is important for the plant’s establishment and growth. If a cutting was water-rooted, transition it to soil once roots are about 1 to 2 inches long. Plant the rooted cutting in a small pot with good drainage, using a well-draining soil mix like a succulent or cactus blend.
After potting, water lightly, allowing excess to drain. Snake plants are drought-tolerant, so water only when the top one to two inches of soil are dry. Place the newly rooted plant in bright, indirect light, which promotes healthy root and leaf development. Snake plants thrive in temperatures between 60°F and 85°F, and generally do not require fertilization until they have developed a healthy root system, typically starting around four to six weeks after potting with a diluted, balanced liquid fertilizer during the growing season.
