Snow, or Dumb Cane, is an evergreen houseplant native to Central America. Joseph Dieffenbach, Austrian royal head gardener, discovered this plant in the 1830s; it earned the moniker Dumb Cane because it causes the tongue to swell if ingested, temporarily rendering the eater unable to speak. It offers attractive foliage on an upright habit, reaching as much as 6' tall. Dark green leaves with cream specks and silvery-green variegation lend a tropical feel to any brightly lit room. Dieffenbachia flourishes with low water, bright indirect light or shade, and high humidity, making it a low-maintenance, distinctive addition to houseplant collections. For a smaller variety, try growing Tiki.
Snow Selling Tips
Sell Snow to customers looking for a low-maintenance, high-impact houseplant. This plant offers many benefits, including attractive foliage, air-purifying capacity, low water needs, and adaptability to various lighting conditions. Create a houseplant collection packed with color and texture by growing Dieffenbachia with Philodendron, Croton, Pothos, Fittonia, Dracaena, and Chlorophytum.

1. Grow this plant in rich, well-draining soil. Remove any spent leaves that fall off and repot the plant when the roots no longer have enough room in the pot.
2. Provide high humidity by misting the foliage with distilled or filtered water or placing the container on a tray of wet rocks. Water when the soil is dry.
3. Maintain temperatures between 70-85 degrees. This plant needs bright indirect light or partial shade.
General Growing Tips For Your Rooted Cutting Liner
For best results with Snow, grow one rooted plug per 6-inch container or two to three per 10-inch container. Use rich, well-drained soil with a pH of 6.0-6.5 and medium feed (200 ppm N with an N-P-K ratio of 3-1-2). Provide light at 2,500 fc and temperatures of 70-85 degrees. This plant flourishes in high humidity between 60-100%. Watch for scale, mealybugs, spider mites, root rot, and bacterial leaf spot.
Flowering
This plant is prized for its attractive foliage.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant.
Height Control
This plant doesn't require PGRs.
Pests
Scout for scale, mealybugs, and spider mites as part of your commercial greenhouse's Integrated Pest Management program.
Mealybugs are small, white, soft-bodied insects that feed on plant sap. They are covered in powdery wax, which gives them a cottony appearance. They reproduce and spread rapidly. Inspect plants regularly for signs of an infestation, including white, cottony masses on foliage. Always check new plants before bringing them into the greenhouse. Remove any highly infested plants from the greenhouse for quarantine or disposal. Introduce beneficial insects like ladybugs, lacewings, and parasitic wasps as biological controls for mealybug populations and apply insecticidal soap or horticultural oils to disrupt lifecycles and feeding. Maintaining a sanitary greenhouse and eliminating debris can deter pest infestations.
Scale are insect pests that feed on plant sap and look like small bumps on leaves or stems. Control damage from this pest by scouting, introducing natural predators, applying horticultural oils or insecticidal soap, and pruning and discarding infested plant parts or whole plants. Be sure to disinfect tools and always use a sanitary growing media and containers. Note that healthy plants are more resistant to pests and disease.
Spider Mites are tiny pests that cause stippling, yellowing, and webbing on foliage by feeding on plant sap. They flourish in warm, dry environments. Use correct water and fertilizing practices; over-fertilizing can attract spider mites. Proper humidity levels, predatory mites or ladybugs, and insecticidal soaps or oils may prevent or address a spider mite infestation.
Disease
Watch for signs of root rot and bacterial leaf spot. Take preventative measures against diseases in your greenhouse, including using sanitary tools, growing media, and containers; watering at the base of each plant; allowing soil to dry between waterings; and providing adequate space and airflow.
Bacterial Leaf Spot results from a bacterial pathogen and causes water-soaked yellow or brown lesions on foliage. These may merge and cause leaves to turn yellow and drop. Prevent bacterial leaf spot by practicing sanitation and hygiene, watering at the base of each plant, and space plants for adequate circulation and light penetration. At the first signs of infection, remove the affected leaves and treat the remaining plants with a copper-based fungicide like hydroxide, sulfate, oxychloride, or octanoate. Use fungicides carefully according to the label's instructions, and be aware that applying copper-based fungicides at high rates or during hot, dry weather can lead to phytotoxicity.
Root Rot occurs in poorly drained or overly wet soil, which becomes the host for several types of fungi. It causes stunted growth, wilting, and root system decay. Prevention is the best treatment, and you will avoid most root rot problems by using clean, well-draining media, appropriate containers, and good watering practices for finishing seedling plugs. Inspect plants for signs of disease regularly. Repot infected plants in well-draining soil, adjust your watering schedule, provide better airflow, and use a fungicide if needed.
Planting Snow Liners
We recommend growing one rooted plug per 6-inch container or two to three per 10-inch container. Use rich, well-drained soil and completely bury the ellepot centered or evenly spaced in the container. Six inch pots are ready for retail sail in 12-16 weeks.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
