The African spear plant, also commonly known as the cylindrical snake plant, is a succulent houseplant that consists of spear-like, pointy-tipped, gray-green, subtly striped leaves. African spear plants grow best in hot, dry climates with sandy, well-draining soil, preferring morning sun to afternoon sun and temperatures above 50 degrees Fahrenheit. This plant is toxic to pets. Read on for our care guide.
The African spear plant, also known by its botanical name Sansevieria cylindrica, is an increasingly popular houseplant admired for its unique cylindrical foliage and minimal care requirements As with any plant, it progresses through different growth stages during its lifespan In this comprehensive guide, we’ll explore the various life stages of the African spear plant from seed to maturity.
Seed Germination Stage
The journey begins when an African spear plant seed is planted. The seed will start to swell and crack open as it absorbs water. Soon, a tiny root will emerge from the seed, growing downwards to anchor the plant and absorb nutrients and moisture from the soil. Next, a small green shoot pokes out and grows upwards. This shoot will eventually form the plant’s first leaves.
Germination can take anywhere from one to eight weeks. Keep the soil moist but not soaked during this stage. Warm temperatures around 70-80°F are ideal for encouraging germination. Once sprouted move the seedling into brighter light.
Seedling Stage
In the seedling stage, the baby African spear plant focuses on root and leaf growth. The first leaves are spear-shaped, although they lack the distinct cylindrical shape of mature foliage. The seedling will only have a few leaves at this point.
Make sure the soil stays moist but doesn’t get waterlogged. Provide plenty of bright, indirect sunlight. As the seedling establishes itself over a period of weeks to months, start allowing the soil to dry slightly between waterings. Fertilize lightly every 2-3 weeks with a diluted houseplant fertilizer.
Juvenile Stage
The juvenile stage begins when the African spear plant is a few inches tall. It will start developing its distinct cylindrical foliage. The leaves emerge straight and become thicker.
Continue providing plenty of light. Allow the soil to dry out further between waterings, but don’t let it get completely dry. Mist occasionally to boost humidity. Start fertilizing monthly. Support leggy growth by staking the plant. Prune off any dead or damaged leaves to encourage bushier growth.
Mature Stage
It can take 2-4 years for the African spear plant to reach maturity. In the mature stage, the plant achieves its full size potential. It forms the signature cylindrical spear-shaped leaves ranging from 2 feet to 6 feet tall.
At maturity, the African spear plant can tolerate more sun and lower watering frequency. Let the soil dry out more before watering but don’t let it get completely parched. Fertilize every 2-3 months during the growing season. Remove any dead foliage or spent blooms promptly.
Flowering
African spear plants may produce flowers as they mature, usually during summer. The flowers are fragrant, tubular-shaped white blooms arranged in sprays emerging from the leaf axils. However, African spear plants rarely flower when grown indoors. Even if they do bloom, the flowers last only a day.
If your plant produces flowers, avoid getting water on the blooms as this can cause Botrytis fungus. Remove spent flowers to encourage prolonged bloom time. Don’t be alarmed if your plant skips flowering altogether, as African spear plants are prized for their foliage.
Factors Affecting Growth Rate
Several key factors influence how quickly African spear plants progress through each life stage:
-
Light – More light equates to faster growth. Provide as much bright, indirect light as possible.
-
Temperature – Warmer temperatures between 65-80°F will boost growth rate.
-
Water – Moist but not soggy soil encourages growth.
-
Soil – A rich, well-draining potting mix provides essential nutrients.
-
Fertilizer – Regular diluted fertilizer satisfies nutrient needs.
-
Pot Size – Shift to a slightly larger pot as the plant grows.
-
Pruning – Removing dead leaves redirects energy into new growth.
Tips for Healthy Growth
Follow these tips to help your African spear plant thrive through each stage:
-
Start with a high-quality seed or plant from a reputable source.
-
Choose a pot with drainage holes and well-draining soil.
-
Allow soil to dry out somewhat between waterings.
-
Provide plentiful bright, indirect sunlight.
-
Maintain warm temperatures around 70°F.
-
Increase humidity through misting and pebble trays.
-
Fertilize regularly during spring through fall.
-
Repot when the roots have filled out the container.
-
Stake and prune the plant as needed.
-
Keep an eye out for common pests like spider mites.
-
Avoid overwatering, which can lead to root rot.
With the right care and conditions, you can keep your African spear plant thriving through every stage of growth for years of enjoyment! Pay attention to its needs at each phase, and you’ll have a hassle-free houseplant specimen.
Overwintering
African spear plants go dormant in the winter. During the winter months, wait longer between your waterings than you did during the growing season. Watering roughly once a month should be fine. Youll also want to skip fertilizer in the winter.
How to Grow African Spear Plants From Seeds
Seed propagation is more complex than division, mainly because seeds are harder to come by and have low germination success. Germination can take up to six weeks if it occurs at all. Heres how to grow African spear plants from seeds:
- To prepare seeds for planting, soak them in room-temperature water for three to five days.
- Fill a small pot with seed starting mix, moistening the substrate.
- Sprinkle the seeds over the top of the mix.
- Lightly cover with a thin smattering of mix.
- Place the pot on a warming mat or in a warm spot at 68 to 80 F with bright, indirect light.
- Cover the pot with a plastic bag or wrap to create a greenhouse-like atmosphere.
- Once a day, open the plastic covering, giving fresh air to the plant for about an hour.
- Upon noticing growth, entirely remove the plastic.
