Sansevieria Care

Placement

PRO TIP: Most Sansevieria will thrive in a wide range of light conditions from low indirect light, to full sun environments.

Sansevieria, better known as Snake Plants, are hardy specimens that are more tolerant of imperfect environmental conditions than almost any other houseplant. One of the easiest plants in the world to care for, anybody can add a pop of green to their space with one of these! (Sansevieria have recently been reclassified as part of the Dracaena genus). 

Boasting a wild array of variegations and growth patterns across the genus, they are slow growers that thrive in bright light. However, it is their ability to subsist in extremely low light conditions that gained them their popularity, and they are even capable of surviving off of fluorescent light alone. When placing your Sansevieria, ensure it’s not in the direct path of any air vents and try to choose a spot that receives some level of indirect light.

If you are unsure of the lighting conditions in your home of office, we have a guide for how to measure light in your space.

Sansevieria (aka Snake Plant) Care Guide

Sansevieria are called Mother in Law’s Tongues because they’re sharp and will hurt you when you don’t expect it.

Routine Maintenance

PRO TIP: When it doubt, let it drought! The most common mistake made with these plants is overwatering.

Always be sure to assess your plant’s watering needs upon receiving it. Before giving your plant a drink, it is best to check the moisture level in the soil first to ensure it isn’t moist right beneath the surface. Also, consider aerating the soil of your plant before the initial watering. We compact the soil to avoid shifting during transit, so aerating can help the soil breathe and allow moisture to be released.

Sansevieria like to dry out completely between waterings. The most common mistake made with these plants is overwatering. Even if your plant is placed in ample bright indirect light, you won’t need to water it more than once every 10 days (at most) during the growing season. During the winter months or if the plant is in low light, it can need watering as infrequently as once a month. Regardless of its placement though, make sure that you are letting your Sansevieria's soil thoroughly dry between waterings. Sansevieria are susceptible to root rot, so it’s very important that you do not water the plant if you detect any moisture in the soil.

Rotate your plant periodically to ensure even growth on all sides and dust the leaves often so the plant can photosynthesize efficiently. When dusting the leaves, also take the opportunity to inspect the undersides and keep an eye out for pests.

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 Sansevieria and its watering needs and you will have a long and happy relationship.

Frequently Asked Questions

How can I tell if I am overwatering my Sansevieria?

  • Overwatering results in mushy brown stalks. Hold off on watering and prune your plant. Only when the soil is completely dry all the way through the pot is your plant ready for a drink.

How can I tell if I am underwatering my Sansevieria?

  • Though difficult to do, underwatering a Sansevieria is not impossible and results in dry crispy tips on the plant's leaves. If this is the case, prune your plant and increase your frequency of watering.

Can my Sansevieria tolerate really low light?

  • It can, however this is likely to stunt the growth of your plant. Also the risk of overwatering becomes heightened, so take extra care when placing you plant in low light conditions.

How often should I fertilize my plant?

  • In general, house plants will thrive when they are fertilized spring through fall. Fertilize once a month with an organic houseplant fertilizer, following the package instructions for dilution and administration. Greenery NYC uses an organic potting mix with a slow release fertilizer in the soil, so your plant will not need fertilizer within the first 6 months of receiving it.

How often does my plant need to be repotted?

  • For smaller desktop plants, we suggest repotting once every 12-18 months. Typically you want to choose a potting vessel 1”- 2” larger in diameter to allow for growth. Don’t choose a pot much larger than the previous as this could drown the plant's roots. If you prefer to maintain the current size of your plant, repot into the same vessel, providing new soil and trimming away some roots and foliage. Spring or summer is the ideal time to repot as the plant is at its strongest.
  • For larger floor plants, we suggest repotting every 18-24 months. Typically you want to choose a potting vessel 2”- 4” larger in diameter to allow for growth. Don’t choose a pot much larger than the previous as this could drown the plants roots. If you prefer to maintain the current size of your plant, repot into the same vessel, providing new soil and trimming away some roots and foliage. Spring or summer is the ideal time to repot as the plant is at its strongest.

Standard Planter Instructions

All of our Standard Planters include a removable drainage plug to give our customers the option of drainage. While no drainage is sometimes preferred for its aesthetic simplicity, we don't recommend this option for beginners as watering mistakes can be hard to rectify.

Whether you choose to use drainage or not, we always recommend using a layer of drainage (such as our Aeration Stones) at the base of the planter. A drainage layer allows the plant's roots access to oxygen in the pockets between the drainage medium, and a lack of drainage can cause anaerobic damage to your plant.

If you decide to utilize the drainage hole for your pot, make sure to include a Plant Saucer beneath your pot to collect excess water. For most plants in standard planters, we recommend watering about once a week. Water the soil mass until water begins pooling in your Plant Saucer.

With no drainage hole, you will need to be more precise in your watering. While we would love to give you a specific measurement of water to provide for your plant, the reality is that a plant's water requirements vary wildly depending on factors such as light exposure and the overall health of the plant. You will need to learn to tell when the plant is thirsty based on how its foliage looks. Droopy foliage is usually the first sign: when your plant looks a little slumped over that's usually a visual indicator that it's thirsty.

The best solution for checking your plant's moisture level, drainage hole of not, is to use a Soil Probe to determine the moisture content of the soil at the bottom of the planter.

Self Watering Planter Instructions

The Self-Watering Planters require a deep and thorough watering of the topsoil after they are first planted. This is important because the roots of the plants first need to grow into the reservoir in order to drink from it. Water your plant from the top for two to four weeks before using the reservoir. During the dormant seasons, or for plants that have slower growing habits, consider top watering for longer.

TEST: After the initial top water period, fill the bottom water reservoir. If the water in the reservoir is absorbed into the planter, it means the plant is ready for regular reservoir servicing. If not, be sure to continue top watering for a few more weeks until the plant has started drinking from the reservoir.

RESERVOIR SERVICING: Once the reservoir empties on its own, do not refill the reservoir right away. Similar to how humans need a breath of air between gulps of water, most plants require a drying out period. Allow for the reservoir to empty all the way between watering. All plants are different in their needs so the amount of time the reservoir sits empty will need to be determined, but know that for most plants this period is between 1-3 days. 

From here on out, you should rarely topwater the plant while using the reservoir system. Watering from below allows the plant to drink at its own pace, and can help combat certain issues like fungus gnats by allowing the top layer of soil to dry out more. Please note that if your plant's soil dries out too much, it can impair the wicking ability of the Aeration Stones in your planter. If your soil becomes too dry, we recommend giving it a thorough watering.
