Temperature requirements
Axonopus compressus is a warm-season grass plant that requires high temperatures to grow. The optimum temperature range for Axonopus compressus growth is between 20°C and 35°C. If the temperature falls below 10°C, the grass stops growing, and if it exceeds 40°C, the blades of the grass may wither and turn yellow.
Soil requirements
Axonopus compressus requires a well-draining soil that has a pH range of 5.5 to 7.0. The grass thrives in soils that are rich in organic matter and have good moisture retention capacity. It is essential to add organic materials such as compost or manure when preparing the soil for planting. The grass does not grow well in water-logged soils or soil that lacks proper aeration.
Cultivation methods
Axonopus compressus, commonly referred to as carpet grass or broadleaf carpet grass, is a warm-season perennial grass that thrives in tropical and subtropical climates. The plant is comparatively low-maintenance and can be cultivated on various soils and terrain types.
The best time for planting Axonopus compressus is during the spring and summer months when temperatures range between 70°F and 85°F. For germination, the seeds require consistent moist soil and should be planted at a depth of 1/8 inch. The seedlings will begin to emerge in approximately two to three weeks and will need regular watering until they establish strong roots.
Watering needs
Axonopus compressus requires consistent and adequate moisture levels to thrive and maintain its vibrant color. Generally speaking, the plant requires one inch of water per week, either through rainfall or irrigation; however, the water needs may change depending on the local climate and soil conditions.
It's vital to water Axonopus compressus effectively, ensuring that the soil is moistened to a depth of at least six inches. It's advisable to water the plant early in the morning or late in the evening when the sun is less intense to prevent rapid evaporation. Avoid over-watering as it can lead to root rot and cause damage to the plant.
Fertilization
Although Axonopus compressus does not require excessive fertilization, occasional feeding can provide the necessary nutrients for optimal growth and appearance. It's recommended to fertilize the plant during spring and summer using a balanced fertilizer with equal levels of nitrogen, phosphorus, and potassium.
Before applying the fertilizer, ensure that the soil is moist. Apply the fertilizer at the recommended rate and avoid spreading it on the leaves or stems as it can cause fertilizer burn. After application, water the plant thoroughly to aid in the absorption of the fertilizer.
Pruning
Axonopus compressus does not require much pruning as it naturally forms a low-lying mat-like lawn. However, regular mowing can significantly improve the plant's appearance and growth.
The recommended mowing height for Axonopus compressus is between 1 1/2 inch to three inches. Mow the grass when it reaches a height of three to four inches to avoid removing more than one-third of the plant height in a single mow. Remove any clippings or debris from the lawn as they can block sunlight and air from getting to the grass.
Propagation Methods of Axonopus compressus (Sw.) Beauv.
Axonopus compressus, also known as broadleaf carpet grass, is a warm-season perennial grass native to tropical and subtropical regions of the Americas. The grass is commonly grown for its attractive lawn and forage qualities. Propagation of Axonopus compressus can be achieved by several methods, such as seed, vegetative propagation, and sodding.
Seed Propagation
Seed propagation is the most common method of propagating Axonopus compressus. The grass produces small, light-brown seeds that can be sown directly into the soil. The seeds should be scattered on a weed-free and well-prepared seedbed, and covered lightly with soil. Germination typically occurs within two to three weeks, but may take up to four weeks. The seedlings can be transplanted to their permanent location after they have grown to a height of two to three inches.
Vegetative Propagation
Vegetative propagation is another method of propagating Axonopus compressus. This method involves the use of stem cuttings or stolons. The stem cuttings should be taken from mature plants during the growing season, and should be at least six inches long. The stolons, which are modified stems that grow horizontally along the ground and produce roots and shoots at nodes, can be harvested by digging up and dividing established plants. The cuttings or stolons should be planted on a well-prepared seedbed, and watered frequently until they have rooted and established.
Sodding
Sodding is the quickest and easiest method of propagating Axonopus compressus. This method involves laying down strips of pre-grown sod on a prepared soil bed. The sod should be installed during the growing season, and watered frequently until it has established roots into the soil. Sodding is the most expensive propagation method, but it provides an immediate lawn with weed-free coverage.
Propagation of Axonopus compressus can be achieved through seed, vegetative propagation, and sodding. The chosen propagation method will depend on the grower's objectives, resources, and the availability of plant materials.
