Mat sandbur (Cenchrus longispinus)
Also known as: Spiny burr grass
Mat sandbur plants produce sharp burrs that cling to animals and human clothing, aiding in seed dispersal. These burrs help the seeds travel to new areas. Mat sandburs are invasive and can displace native plants.

What Is the Ideal Temperature Range for Mat sandbur?
The ideal temperature range for Cenchrus longispinus is between 77°F and 95°F. This range ensures optimal growth as it supports vital physiological processes such as photosynthesis and transpiration. At these temperatures, the plant can efficiently absorb nutrients and maintain its metabolic rate. Providing a warm environment conducive to its growth habits ensures that Cenchrus longispinus can thrive.
What Soil is Best for Mat sandbur?
Cenchrus longispinus thrives in soil that drains well. This prevents waterlogging which can lead to root rot, ensuring the roots get sufficient air and nutrients. While not very demanding, Cenchrus longispinus benefits from moderately fertile soil, which aids in optimal growth and sustenance of its spiny seed heads. Incorporating some organic matter into the soil can enhance its structure and nutrient availability, offering the plant a healthy growing medium that supports its robust nature.
How to Fertilize Mat sandbur?
For Cenchrus longispinus, it's advisable to use a balanced liquid fertilizer that is diluted to half strength. Apply approximately 1 cup per plant each time you fertilize, ensuring not to saturate the soil.
How to Prune Mat sandbur?
Begin by wearing gloves to protect your hands from the spiny burs of Cenchrus longispinus. Use sharp pruning shears to cut back any stems that appear overgrown or are encroaching on neighboring plants. Aim to trim back the plant by about one-third to maintain its shape and manage its spread. Dispose of all cut material properly to prevent unwanted reseeding. To prevent the spread of Cenchrus longispinus, it's essential to prune before the plant sets seed. Look for seed heads forming in mid to late summer and cut them off promptly. This will help reduce seed distribution and limit the plant's invasiveness in your garden.

How to Propagate Mat sandbur plant?
1
Collect mature seeds from the plant once the seed heads have dried and turned brown. Ensure they are fully dried before storing or planting to prevent mold.
2
Fill a sterile container with potting mix, scatter seeds evenly, and cover them lightly with soil. Ensure they are not deeply buried to facilitate sprouting.
3
Water the seeds gently using a spray bottle to avoid displacing them. Maintain moisture without waterlogging, as it can lead to seed rot.
How to Repot Mat sandbur plant?
1
Repotting for Cenchrus longispinus should occur when roots start to emerge from the drainage holes, indicating that the plant is becoming root-bound. Additionally, if growth appears stunted despite healthy care, it's time for a new pot. Spring or the beginnings of summer are ideal since the plant is entering its active growth phase, facilitating better adjustment to new conditions.
2
Opt for a pot that is only an inch or two larger than the current one. The material should have good drainage capability, such as terracotta, which prevents waterlogging by allowing moisture to evaporate. This is critical because Cenchrus longispinus does not thrive in soggy conditions, and a breathable pot helps keep the roots healthy.
3
Select a well-draining sandy soil mix to mimic the plant’s natural environment. This choice ensures adequate drainage, preventing root rot by allowing excess water to escape quickly. The sandy texture should allow for good airflow to the roots, promoting a robust and healthy root system over time.
