Radishes are the perfect urban crop - they're quick-growing and space-efficient. So, grab your watering can, clear off that windowsill, and get ready to prove that you don't need acres of land to be a farmer. I'm here to guide you through your new favorite hobby.
Radishes need 4-6 hours of direct sunlight. Indoors: Can be grown in deep pots with bright light or hydroponically using grow lights for 10-12 hours.
Keep soil consistently moist. Indoors, monitor soil moisture frequently; outdoors, water regularly, especially in full sun conditions. Mulching helps retain moisture.
Radishes are a cool weather crop and love 50-70°F, ideally 60-65°F. Plant outdoors in March-May and August-September in NYC zone 7b. Cool temperatures prevent bolting.
Indoors: 6-8" wide, 6" deep, 1 gallon; Outdoors: 6-8" wide, 6-8" deep, 1-2 gallons
Radishes prefer loose, well-draining potting mix with compost from kitchen scraps or well-rotted manure.
Apply low-nitrogen, high-phosphorus fertilizer 5-10-10 every 3-4 weeks. Organic options: bone meal, rock phosphate, compost. Consistent, moderate feeding supports rapid root growth.
Radishes are ready for harvest 20-30 days after planting, or when the roots are 1 inch in diameter. Prefers cooler temperatures; harvest promptly to avoid bolting.
Remove yellowing leaves to keep the plant healthy. Regular care produces crisp, spicy radishes.
Yellow Leaves: Ensure good drainage, let soil dry. Pests (Aphids): Spray with soapy water or neem oil. Slow Growth: Use balanced fertilizer. Wilting: Water consistently, avoid waterlogging. Diseases (Downy Mildew): Improve air circulation, use fungicide.
There are around 10-15 varieties of arugula gardeners commonly grow. One of the perks of growing arugula at home is the opportunity to experiment with different varieties that you won't find at the grocery store.
