Organic Gardening

Feed & protect without buying

Feed

Compost at Sowing

Work fine compost into the top layer of soil before sowing. Radishes grow fast and need little else — overfeeding causes leafy growth.

Pest

Garlic Spray for Flea Beetle

Steep 6 garlic cloves in 1L water overnight, strain, and spray on seedlings. Reapply after rain.
