- âĒ Root swelling, distortion, and excessive branching
- âĒ Yellowing of leaves (chlorosis), especially lower leaves
- âĒ Wilting during hot periods despite adequate soil moisture
- âĒ Stunted growth and reduced vigor
- âĒ Reduced flowering and fruit production

- âĒ Discolored or necrotic root tips
â What Causes Root-Knot Nematodes on Blood Banana?
- â Infection by microscopic roundworms (Meloidogyne incognita, M. javanica, M. arenaria)

ðą How to Care for Blood Banana to Prevent Root-Knot Nematodes?
ð§ How to Water
Keep the soil evenly moist. In containers, water when the top 2-3 cm is dry, usually every 3-5 days in warm weather. Never let it sit soggy or in a saucer of water. In winter, when growth slows, water much less.
âïļ Lighting
Bright light to full sun. In hot, dry climates, light afternoon shade protects the red markings. Indoors, give it the brightest window with a few hours of sun and turn the pot now and then.
ðŠī Ideal Soil
Rich, organic soil that holds moisture but drains quickly, pH 5.5 to 7.0. For pots, mix potting soil, compost and perlite.
