Care Difficulty

This Mason’s Congo Sansevieria is typically low maintenance, and the soil’s ability to drain and the amount of light are the most significant factors for this beauty.

Growth Rate

The Dracaena Masoniana reaches a height of 1-2 feet when grown inside a home. This plant will usually produce more actively during spring and summer.

Most Dracaena species, including the Whale Fin, are known to grow slowly, but this plant is even slower than its brothers.


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.


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.


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.

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.


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.

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.

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:


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.
