On the other hand, in partial shade, the plant can thrive with only 3-4 hours of direct sunlight daily. However, insufficient light may cause the plant to wilt or become spindly and leggy.
Temperature Requirements
Axonopus affinis Chase is adaptable to a wide range of temperatures but prefers warmer temperatures. The plant can grow in temperatures ranging from 15 degrees Celsius to 35 degrees Celsius. However, it grows best under temperatures between 23 to 28 degrees Celsius.
Soil Requirements
Axonopus affinis Chase grows well in a variety of soil types, but it prefers well-draining, nutrient-rich soil with a slightly acidic pH ranging from 5.5 to 6.5. The plant requires adequate moisture but should not be planted in waterlogged soil as it can cause root rot. Adding organic matter such as compost to the soil can help improve its fertility and water-holding capacity, providing optimal growth conditions for the plant.
Cultivation Methods
Axonopus affinis Chase, commonly known as carpet grass, is a warm-season grass that thrives in tropical and subtropical regions. It prefers damp, shady areas in the yard, making it an excellent choice for lawns or landscaping near ponds, fountains, or other sources of water. The grass is easy to cultivate and grow, making it a popular choice in many regions.
Cultivate the land by removing any weeds or stray grass before planting Axonopus affinis. Ensure that the soil is moist and well-drained. Sow the grass seeds at a depth of 3-5mm and cover them with a light layer of soil. Keep the soil moist until the grass has established. The grass should be watered regularly, but avoid overwatering, as this can lead to fungal diseases.
Watering Needs
Axonopus affinis prefers frequent watering, but it does not tolerate waterlogged conditions. Water the grass frequently but avoid overwatering, which can cause soil compaction and root rot. Irrigate the lawn slowly and deeply, preferably early in the morning or late in the evening, to allow the roots to absorb the water fully.
During the dry season, reduce the frequency of watering, but ensure that the soil does not dry out completely. The grass can tolerate short periods of drought, but prolonged drought can lead to yellowing and stunted growth.
Fertilization
Axonopus affinis requires regular fertilization to maintain a lush and vibrant lawn. Apply a slow-release, balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium every six to eight weeks. Use a broadcast spreader to apply the fertilizer evenly over the lawn surface.
Avoid fertilizing the grass during the dry season, as this can lead to fertilizer burn. Instead, fertilize the grass before or after the rainy season, when the grass is actively growing.
Pruning
Prune Axonopus affinis regularly to maintain an even, well-manicured lawn. Use a lawnmower or grass trimmer to cut the grass to a height of 5-7cm, taking care not to scalp the lawn in the process. Scalping can cause injury to the grass, making it more susceptible to pests and diseases.
Axonopus affinis can tolerate frequent mowing, but avoid cutting more than a third of the grass length at once. This can stress the grass and weaken its growth.
Propagation methods of Axonopus affinis Chase
Axonopus affinis Chase, also known as tropical carpet grass, is a warm-season perennial grass commonly found in tropical and subtropical regions. It is an excellent option for lawns, gardens, parks, and sports fields, thanks to its dense growth and fast-spreading nature. There are several methods for propagating Axonopus affinis Chase, including:
Seed propagation
The most common method for propagating Axonopus affinis Chase is through seeds. The seeds of this plant are readily available in the market. To propagate Axonopus affinis Chase through seeds, the following steps should be taken:
- Collect the seeds from mature plants during the flowering season
- Clean the seeds by removing any debris
- Sow the seeds on prepared soil beds
- Water the seeds regularly and ensure they are kept moist until germination
- Transplant the seedlings to their final planting location after they have developed a few leaves and established a good root system
Vegetative propagation
Vegetative propagation is another method used to propagate Axonopus affinis Chase. This method involves taking a part of the parent plant and planting it to establish a new plant. The following methods can be used for vegetative propagation:
- Stolon propagation: This method involves planting the stolons cut from the parent plant in a well-prepared soil bed. The stolons should have at least 2-3 nodes, and they should be planted horizontally to facilitate rooting.
- Sod propagation: This method involves cutting sods of the parent plant and planting them in a well-prepared soil bed. The sods should be well-watered and kept moist until they establish roots and begin to grow.
- Division: Division involves separating the parent plant into smaller sections and planting them in a well-prepared soil bed. Division is usually done during the plant's dormant season, and the sections should have a good root system and foliage.
Regardless of the method used, it is important to provide the newly propagated plant with proper care and maintenance to ensure its survival and growth.
