Care at a glance

Know your plant

Dracaena masoniana belongs to Asparagaceae; Sansevieria masoniana is its earlier botanical name. [11]

Mila's catalogue names this plant Dracaena masoniana, variegated form. [19]

Logee's describes Variegated Whale Fin with broad, upright, paddle-like leaves carrying green and yellow variegation. [13]

Light

Give Whale Fin bright indirect light. Shield the leaves from intense direct sun that can scorch them. [12]

Watering

  1. Let the potting mix dry between waterings. Avoid repeatedly wetting a mix that is still damp. [12]

  2. Feel the mix and lift the pot to assess moisture. Recheck as light, growth and room conditions change. [1]

  3. Water evenly through the mix, allow excess to drain, then empty the saucer or cover pot. [1]

Soil and pot choice

Use an aerated, well-drained potting mix; coarse mineral material such as perlite can help maintain air spaces. [12]

Choose a container with drainage holes. Keep the nursery pot above water collected in a decorative cover pot. [1]

Temperature and humidity

Keep room conditions steady, away from cold glass, drafts and blasts from heating or air-conditioning vents. [10]

Snake plants suit moderate to warm indoor conditions and tolerate low humidity. [17]

Feeding

Feed during active growth with houseplant fertilizer at the label rate. Reduce or withhold feeding when growth slows. [10]

Repotting

  1. Inspect the roots when the container becomes crowded or dries unusually quickly. Repot during active growth into a slightly larger draining pot. [8][2]

  2. Use fresh mix and retain the existing planting depth. Water it in and let excess drain. [2]

Propagation

  1. For variegated snake plants, choose division or well-rooted offsets. Leaf-section cuttings tend to produce green offspring. [16]

  2. Remove the plant gently from its pot. Separate a rooted section or offset, using a clean tool where needed; retain both roots and leaves on each piece. [18]

  3. Pot each division into a draining container with fresh mix. Keep the planting depth consistent and monitor the divided plant as it establishes. [18][2]

Pruning and foliage care

Remove badly damaged leaves at their base. Leave healthy leaves intact. Wear gloves when cutting; the sap can irritate skin. [16]

Children and pets

Safety

NC State identifies Dracaena masoniana as toxic to cats and dogs if swallowed. [12]

Eating plant material can still upset a pet's stomach. [9]

Keep plants, fallen leaves and cuttings away from pets that chew them. [9]

For suspected poisoning or signs of illness, contact your veterinarian or ASPCA Poison Control at 888-426-4435. Provide the botanical name. [5]
