PRO TIP: Also known as the “Dumb Cane” Dieffenbachia have a toxic sap that can cause the tongue to swell. Keep out of reach of pets and children.
The Dieffenbachia is a lush and showy plant, perfect for your home or office. It adapts well to varied light situations and can even survive on fluorescents alone. Often called “Dumb Cane” due to the toxic sap that causes irritatation when ingested, this plant is not ideal for a space with small children, or pets. This plant will thrive in a spot that receives bright ambient light. Direct sun will scorch the leaves, so if the sun shines strongly through your window be sure to move the plant away from the direct stream of light. In an office space, the Dieffenbachia can adapt to fluorescent lighting, though it may take some time to adjust.
We also have a guide for how to measure light in your space.
The Dieffenbachia's broad, patterned leaves make it an excellent companion in plant clusters.
PRO TIP: The leaves of the Dieffenbachia are expressive and will often let you know the state that the plant is in. A thirsty plant's leaves will crinkle and become dry, eventually falling off, while an overwatered plants leaves will slake off and leave behind a slimy residue on the stalk.
Always be sure to assess your plants watering needs upon receiving it. Before giving your plant a drink, it is best to check the moisture level in the soil first. Dieffenbachia prefer soil that is consistently and lightly moist, but not soggy. Generally you want to water when the top 1”- 2” of the soil is dry. If the soil is kept too moist, the plant can acquire root rot and decline in health. If you allow the soil to dry completely, the leaves will brown and the plant will droop and wilt. Consider aerating the soil of your plant before the initial watering. We compact the soil to avoid shifting during transit, so aering can help the soil breath and allow for moisture to be released.
Heat from radiators, and cool drafts alike can cause the plant’s leaves to yellow and curl, so keep it in a spot with temperatures above 60 degrees. The Dieffenbachia is susceptible to spider mites, so placong it out of the direct stream of air vet will aid in prevention. Be sure to keep this plant out of reach of pets and children as it is mildly toxic when ingested and can cause temporary irritation.
For regular upkeep, dust the leaves often so the plant can photosynthesize properly. When dusting, take the opportunity to inspect the underside of leaves and keep an eye out for pests. Using fertilizer spring through fall will enhance your plants foliage and promote new growth. Rotate your plant periodically to ensure even growth on all sides.
Remember each plant is a unique living thing and may have varying needs, especially in their individual locations. Pay attention to the condition of your Dieffenbachia and its watering needs and you will have a long and happy relationship.
There are two types of standard planters offered by Greenery NYC—those with drainage holes, and those without. Within those two categories are an array of sizes and styles to choose from. All these factors play a role in the quantity and frequency of water given to your plant.
Plants purchased in a pot without a drainage hole have been set up with a built in drainage system. A layer of hydro stones (porous, absorbent material made of recycled glass) has been placed beneath the soil to act as a reservoir and retain any excess water that flows through the soil. You will need to be slightly more cautious not to pour too much water into these containers as there is no way for the water to escape. We suggest pouring small amounts of water in bit by bit, until you have reached the desired moisture level in the soil.
For plants with a drainage hole, water until it begins to come out the bottom of the pot and into the catch tray.
Always be sure to assess your plants watering needs upon receiving it. Refer to the routine maintenance section for moisture requirements.
The self-watering planters require a good, solid watering of the topsoil after they are first placed. This is important, because the roots of the plants need to grow into the reservoir in order to drink from it. Follow the standard planter instructions for the first four weeks until the reservoir is ready to be tested.
TEST: After four weeks, fill the reservoir until the red indicator reaches the MAX line. If the indicator goes down over the first few days, it means the plant is ready for reservoir servicing. If not, be sure to continue top watering for a few more weeks, until the plant starts drinking from the reservoir.
RESERVOIR SERVICING: Once the indicator goes down, do not refill the reservoir right away. Similar to how humans need a breath of air between gulps of water, almost all plants require a drying out period. Dieffenbachia need to dry out slightly between waterings, so once the reservoir is empty wait a few days before you refill. Always allow for the reservoir to empty all the way, and after the drying out period, be sure to fill it until the indicator reaches the MAX line.
From here on out, you should NEVER topwater the plant. If you water from the top, it can drown the plant. In the Self Watering Container, the top layer of soil will eventually become extremely dry and hard, and may even pull away from the edges of the pot. This is not a cause for concern, but simply because the plant is drinking directly from its roots in the water reservoir.
Step 1: Top water for two weeks. The indicator will look empty, like the picture above.
Step 2: Fill the reservoir until the red indicator reaches the MAX line.
Step 3: Watch the indicator over the next day or two. If it goes down on its own, it means the roots of the plant have grown into the reservoir. From here on out, ONLY water in the reservoir.
