Image: Proper Onion Planting Depth and Spacing
Published: December 16, 2025 at 9:15:20 PM UTC
Educational diagram illustrating how to plant onion sets with correct depth and spacing in soil, ideal for gardening guides and horticultural instruction.
This educational diagram presents a clear and realistic visual guide for planting onion sets with proper spacing and depth in a garden bed. The image is rendered in high-resolution landscape orientation, using a semi-realistic style that combines technical clarity with natural textures and colors.
The foreground features freshly tilled soil in rich brown tones, with subtle shading and clumping that suggest a well-prepared garden bed. Three onion sets are positioned in a horizontal row across the soil surface. Each onion is depicted in a different stage of planting to illustrate depth and placement: the left onion is fully planted with only its tapered top visible above the soil, the middle onion is partially planted showing more of its body, and the right onion is unplanted, resting on the soil surface.
The onion sets are golden-brown with a dry, papery outer skin and a small stem remnant protruding from the top. Their teardrop shape and fine surface texture are rendered with realistic shading and highlights, suggesting light from the upper left corner.
Two labeled measurements are included to guide spacing and depth: a horizontal dotted line with arrowheads spans the distance between the left and middle onions, labeled “5–6 inches” in black text above the line. A vertical dotted line with arrowheads indicates the planting depth from the base of the fully planted onion to the soil surface, labeled “1–1 1/2 inches” to the right of the line.
The background features a soft-focus grassy field in green hues, transitioning to a pale greenish-blue sky with a subtle gradient. The horizon line is slightly above center, creating a sense of depth and open space.
Overall, the diagram effectively communicates the key horticultural principles of onion planting: consistent spacing between sets to allow for bulb development, and shallow planting depth to ensure proper growth. The composition is clean and uncluttered, making it ideal for use in gardening manuals, educational posters, or online instructional content.
