Small carpetgrass (Arthraxon hispidus)
Also known as: Creek grass, Hairy jointgrass
Arthraxon hispidus, also known as small carpetgrass or hairy jointgrass, originates from East Asia. It was unintentionally introduced to the United States, where it has since become invasive. Managing this weed can involve manually removing it before it seeds or using a wetland-specific herbicide.

How to Water Small carpetgrass?
Arthraxon hispidus thrives best when its soil is evenly moist but not waterlogged. Aim to provide around 250 ml of water each time to ensure the roots receive sufficient hydration without drowning. The water should permeate the soil completely, reaching the deeper roots but avoid pooling on the surface.

What Is the Ideal Temperature Range for Small carpetgrass?
Arthraxon hispidus thrives best in temperatures between 65°F and 77°F. This range provides optimal conditions for growth and overall health. The plant performs photosynthesis efficiently and does not experience undue stress, making it the best temperature range for supporting its metabolic activities.
What Soil is Best for Small carpetgrass?
Arthraxon hispidus thrives in well-drained soil, which prevents waterlogging and root rot. Providing a substrate where excess water can easily percolate away ensures the roots remain healthy and able to absorb nutrients, leading to a more vigorous growth. This plant benefits from soil with moderate nutrient content. A balanced level of macronutrients ensures that the plant has enough fuel for photosynthesis without the risk of nutrient burn or excessive growth, aiding in maintaining a stable structure. Enriching the soil with organic matter can significantly enhance moisture retention and nutrient availability. This is beneficial for Arthraxon hispidus, as it improves soil structure, provides essential nutrients, and fosters beneficial biological activity.
How to Fertilize Small carpetgrass?
Arthraxon hispidus should be fertilized with a moderate amount of nutrients to encourage strong growth. Typically, about 1/4 to 1/2 teaspoon of liquid fertilizer per gallon of water is efficient, while slow-release granules can be sprinkled sparingly on the soil's surface at a rate of approximately 1 ounce per square foot.
How to Prune Small carpetgrass?
Use sharp, clean shears to clip back overgrown areas, focusing on damaged or diseased stems. Ensure cuts are made at a 45-degree angle to prevent water accumulation and promote healthy regrowth. Remove some of the interior stems to open up the plant structure. This practice allows for better air circulation, reducing the risk of fungal diseases and allowing sunlight to penetrate the inner parts of the plant.

How to Propagate Small carpetgrass plant?
1
Collect mature seeds from the plant and soak them in water for 24 hours to soften their outer shell, aiding germination.
2
Select healthy stems free of disease and pests, cutting a length of 4-6 inches below a node to improve rooting success.
3
Carefully dig around the base of the plant to unearth the root ball. Separate clumps ensuring each division has roots and shoots.
How to Repot Small carpetgrass plant?
1
Arthraxon hispidus signals it's time for repotting when roots start outgrowing the pot, sneaking out through drainage holes, or when the soil compacts too much affecting drainage and aeration.
2
Opt for a pot that's a couple of inches larger in diameter than the current one. This prevents too much moisture retention which can cause root rot, and provides enough room for the plant to grow.
3
A well-draining loamy mix is ideal. It retains enough moisture for the roots without causing waterlogging, and it enriches the plant with nutrients necessary for vibrant growth.
