The Guiana Chestnut, commonly known as the Money Tree (Pachira aquatica), is a tropical wetland tree native to Central and South America. It is popular as a houseplant due to its braided trunk and lush, palmate leaves. However, brown leaf tips can indicate underlying issues affecting its health.
Brown tips on Guiana Chestnut leaves are typically a stress response caused by environmental or care-related factors. Below are the primary reasons:
3.1 Overwatering: Guiana Chestnut prefers moist but well-drained soil. Soggy conditions lead to root rot, impairing water uptake and causing leaf tips to brown.
3.2 Underwatering: Prolonged drought stresses the plant, leading to dehydration and browning at the leaf margins. The plant’s tropical origin means it thrives in consistent moisture.
Native to humid environments, the Guiana Chestnut suffers in dry indoor air. Low humidity causes leaf tips to dry out and turn brown. Ideal humidity should be 50% or higher.
5.1 Too Much Direct Sunlight: While the plant tolerates bright light, intense direct sun can scorch leaves, leading to brown tips.
5.2 Insufficient Light: Inadequate light weakens the plant, reducing its ability to sustain healthy foliage, which may manifest as browning tips.
6.1 Fertilizer Burn: Excessive fertilization causes salt buildup in the soil, damaging roots and resulting in brown leaf edges.
6.2 Nutrient Deficiency: Lack of essential nutrients like potassium or magnesium can lead to marginal leaf necrosis (browning).
Tap water with high chlorine or fluoride content can cause leaf tip burn. Using filtered or distilled water helps prevent chemical-induced damage.
Guiana Chestnut prefers temperatures between 60–75°F (15–24°C). Cold drafts or sudden temperature fluctuations can stress the plant, leading to brown leaf tips.
Spider mites, aphids, or scale insects can sap nutrients from leaves, causing localized damage, including browning. Regular inspection and treatment are essential.
If the plant outgrows its pot, roots become cramped, reducing water and nutrient absorption. Repotting every 2–3 years prevents this issue.
