ðą How to Care for Carrot Fern to Prevent Aphids?
ð§ How to Water
Keep the soil evenly moist year-round, watering as soon as the top centimetre or two starts to feel dry -- roughly once a week indoors, more often in hot weather. Never let the pot sit dry, but always use a pot with drainage so the roots are not waterlogged.
âïļ Lighting
Give it dappled sunlight to bright shade, such as light filtered through a tree canopy or a spot a few feet back from an east- or north-facing window. Direct, harsh sun will scorch the delicate fronds, while very deep shade slows growth further.
ðŠī Ideal Soil
Plant in a humus-rich, well-draining mix -- a standard potting mix amended with leaf mould, compost or peat-free organic matter works well. It tolerates loam or sandy soils and a wide pH range, so drainage and organic content matter more than exact soil type.
