Simply put, it’s an underground stem that grows horizontally, producing new plants from nodes along the way. Whether you’re looking to grow turmeric for its medicinal properties or add some exotic flair to your kitchen with ginger, understanding how to propagate, care for, and identify rhizomes is essential. In this article, we’ll delve into the world of rhizome plants, exploring their benefits, types, and expert tips on propagation, pests, and diseases.
What Are Rhizomes?
So, you’re curious about rhizomes and want to know more about what they are. Let’s dive right in and explore the basics of these fascinating underground plant structures!
Definition and Explanation
Rhizomes are a unique type of plant growth that may seem mysterious to those who have never encountered them before. To put it simply, a rhizome is an underground stem that grows horizontally, producing new plants at its nodes or joints. This means that a single rhizome can give rise to multiple stems and roots, essentially creating a network of interconnected plants.
The key characteristic of a rhizome is its ability to store nutrients and energy, allowing it to survive for extended periods without sunlight. This adaptability enables rhizomes to thrive in environments where other types of plants might struggle to survive. For example, many invasive species like kudzu and bamboo use their extensive network of underground rhizomes to outcompete native vegetation.
In contrast to other types of plant growth, such as roots or stems, rhizomes have a unique structure that allows them to produce new shoots and roots at their nodes. This process is often accompanied by the production of adventitious roots, which can arise from any node on the rhizome.
Types of Rhizomes
As you explore the world of rhizomes, you’ll encounter various types that play different roles in plant growth and survival. Let’s delve into three primary types: stolons, tubers, and corms.
Stolons are horizontal stems that produce new plants at their tips. They allow plants to quickly colonize an area by spreading outwards, often forming dense mats of vegetation. Take the popular Strawberry Plant (Fragaria x ananassa), for instance – it produces stolons with nodes that eventually develop into new plants.
Tubers are underground storage organs that store food and water, helping plants survive harsh conditions. They’re typically swollen stems or roots modified to hold reserves, such as potatoes (Solanum tuberosum). To grow tuber-producing plants, ensure they receive adequate sunlight and moisture to stimulate root growth.
Corms, on the other hand, are short, swollen underground stems that store energy for new growth. They’re often mistaken for bulbs but have distinct characteristics, like gladiolus (Gladiolus spp.). When planting corm-based species, make sure to plant them at the correct depth and provide suitable soil conditions for optimal storage organ development.
When cultivating rhizome-bearing plants, it’s essential to understand their growth habits and requirements. By recognizing the differences between stolons, tubers, and corms, you can better care for your plants and encourage healthy growth.

In terms of watering, rhizomes prefer moist soil, but over-watering is the most common mistake made when growing these plants. To prevent this, make sure the pot has good drainage holes and allow the top inch of soil to dry out between waterings. A general rule of thumb is to water your rhizome plant when the top 1-2 inches of soil feel dry to the touch.
To avoid under-watering, check the moisture level by sticking your finger into the soil up to the first knuckle. If the soil feels dry at this depth, it’s time to water. Avoid getting water on the leaves or crown of the plant to prevent rot and fungal diseases.
Propagation Methods
When it comes to propagating rhizomes, you have several methods at your disposal. One of the most common and straightforward ways is through division. This involves separating the roots from the mother plant, making sure each section has a healthy portion of rhizome and some roots attached. You can then plant these divisions in well-draining soil, water them thoroughly, and provide the right conditions for growth.
Another method is layering, which involves bending a stem down to the ground and securing it with a rock or a U-shaped wire. As the stem develops new roots, you’ll know it’s ready to be cut from the mother plant and potted up on its own. This technique allows you to produce multiple plants from a single stem.
For those who want a more controlled environment, tissue culture is an option. This involves taking small pieces of rhizome tissue, sterilizing them, and growing them in a nutrient-rich medium until they develop into new plants.
