Care Guide
How to Water
Water approximately every 10 days, letting the top 5 cm of soil dry out between sessions. Once established, it is highly drought-tolerant â avoid overwatering to prevent root rot.
Lighting
Requires full sun for at least 6 to 8 hours daily for best growth and flowering. In partial shade, growth becomes less vigorous and plumes are smaller.
Ideal Soil
Prefers well-drained soils of average to low fertility. Tolerates sandy, loamy, and poor soils. Ideal pH ranges from 5.5 to 7.5. Avoid waterlogged conditions.
Recommended Pot
Terracotta or stone pots for outdoor gardens; in containers, choose wide pots with good drainage holes.

Common Problems
Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Meaning & Symbolism
Symbol of resilience and natural beauty, fountain grass represents graceful movement and adaptability to challenging conditions.
