Potting
Choose a ceramic or terracotta container of moderate size for your planting needs. This plant develops astonishingly and may become top-heavy as it matures. A significant requirement is that the pot has at least one drainage hole for the plant to drain. Long-term exposure of your Whale Fin Snake Plant to soggy soil could be fatal.
Repotting
Moving your Whale Fin Sansevieria to a larger container gives its roots more room to grow. When it is time to repot a plant, you will often observe roots growing through the drainage holes.
This tropical plant should often be repotted every year or two. When filling the new pot, replacing the old, nutrient-deficient soil with a fresh batch of cactus and citrus potting soil is advisable.
Soil
Mason’s Congo Sansevieria is a low-maintenance plant that requires cactus and citrus potting soil or succulent potting mix to thrive. If you intend to create your own soil mixture, we suggest including gravel, sand, pumice, and perlite.
Your Sansevieria plants will appreciate the soil being kept dry at all times. Nonetheless, good drainage and aeration are essential requirements for all soil types.
Here are some potting mixes we recommend:
pH
Dracaena Masoniana requires a soil pH of approximately 5.5-7.5, which is alkaline to neutral. If you are concerned about soil acidity, you can purchase a simple pH testing kit online and do a soil analysis.
If you are concerned that the pH level is excessively high, sulfur or aluminum sulfate can be used to rectify it.
In the interim, you can modify your soil’s pH using baking soda, calcitic or dolomitic lime, or wood ash if it is too low.
Water
When watering Whale Fin Snake Plant, you should aim for dry soil. Insert your finger into the pot or purchase a soil moisture meter to measure soil moisture. Dracaenas should be watered until the top two inches of soil are completely dry.
One of the most prevalent causes of indoor plant death is overwatering. When in doubt, remember that it is safer to submerge the Whale Fin Snake Plant than to overwater it. Also, ensure you have soil that drains quickly and a container with drainage holes to prevent excessive water accumulation.
Light
Whale Fin Sansevieria prefers bright indirect light for approximately 6-8 hours daily. Keep in mind that you’re attempting to replicate how it grows in the forests of Congo. In most cases, placing this plant near an east or west-facing window works fine.
When its leaves turn yellow, you’ll know your Whale Fin Sansevieria is getting too bright light. Conversely, if its leaves lose their sheen and grow even slower, the plant needs more light. Avoid putting your Whale Fin Sansevieria in direct sunlight, as this could severely damage or even kill it.
Fertilizer
The Mason’s Congo Sansevieria’s growing season is in the spring and summer. During this time, fertilize your plant once a month using a balanced, water-soluble fertilizer. Sansevierias are light feeders, so when this plant’s development naturally slows in the colder seasons, you don’t need to fertilize.
Propagating Whale Fin Sansevieria
Perhaps you’re eager to see new leaves emerge on your Whale Fin Sansevieria. In this instance, you might prune the stem to promote the development of new growth points. The trimmed-back cuttings can then be used to propagate a new plant!
We have provided a variety of propagation options for your consideration.
Today’s challenge, should you choose to accept it, is to take a photo of a plant and share it.

Pests, Diseases, And Other Problems
The Whale Fin Sansevieria is resistant to illness and pests. Here are some frequent ailments, diseases, pests, and their respective treatments.
Scale Insects
Adult scales are stationary and covered in a waxy covering, but they give birth to incredibly tiny crawling insects.
You can scrape off armored scales, but you must do so carefully using an old ID card or your fingertips. Take care not to rip your Whale Fin Sansevieria’s leaves.
Scale insects can be suffocated with insecticide soap, horticultural oil, or neem oil. When you observe active crawlers on a plant, treat it with a broad pesticide. After a week, administer a second application. We propose the following products:
Mealybugs
Your Dracaena Masoniana can be infested with mealybugs. If you discover these microscopic parasites, which can be distinguished by their white “fluff,” you must act swiftly to prevent their spread.
With rubbing alcohol on a cotton ball, wipe the Dracaena’s leaves to eliminate apparent mealybugs.
In addition, 5mL of neem oil, 500mL of water, and 10 drops of liquid soap can be combined (as an emulsifier). A monthly application of this solution will make your plant leaves appear clean and glossy, but it will also prevent mealybugs from populating your houseplant.
Brown Leaf Tips
The edges of your Whale Fin Snake Plant’s leaves may turn brown if it’s not getting the sufficient amount of moisture that it needs, both from the air and through its roots. Water your plant on time and check if the humidity level in its location is consistent with its needs.
You may also need to consider the amount and frequency of applying fertilizers. Overfeeding can burn your houseplants’ foliage, and this is typically manifested as browning edges on their leaves.

Yellow Leaves
Several circumstances can induce the yellowing of the leaf edges on a Mason’s Congo Sansevieria. One possibility is that it is not receiving sufficient sunshine, and it is also possible that the plant gets excessive or insufficient water.
To promote new growth and avoid the spread of degradation, it is necessary to prune yellow leaves. Moreover, they might be unsightly and unsettling to view. Simply remove the leaves with a pair of sharp, sterile shears.
Root Rot
Overwatering and inadequate drainage are the two most common causes of root rot. Because root rot is frequently fatal and permanent, prevention is of the utmost significance.
Plant your Dracaena in cactus and citrus potting soil and maintain a dry environment for it. Water the soil just when the top two inches are fully dry.
