Do radishes need full sun or shade?

Radishes prefer balanced sunlight, doing best with 4-6 hours of direct sun daily. An easterly exposure gives them the benefit of the morning sun, while afternoon shade is best in hot climates. Too much sun makes them bolt and turn bitter. I orient the beds to face east, so they receive no harsh afternoon sun.

Temperature management directly relates to sunlight requirements. For radishes, when the temperature reaches above 85°F (29°C), they require shade. Bolting occurs when flowering happens before conditions are suitable for root development. All you need to do is ruin the root. Use shade cloth or plant them next to something bigger. My bean trellises make natural summertime shade in the afternoons. If you garden in pots, move your pots to shaded ground.

Container gardening requires special attention to sunlight. Pots heat up faster than the surrounding soil. Move them to shady places at the hottest times. Use light-colored pots to reflect excess heat. I rotate my window boxes daily to ensure they receive an all-around sun treatment. Water thoroughly in the morning and again in the evening, especially during hot spells, to minimize the risk of the plants bolting from sheer stress.

Recognise sun stress indicators early. If the leaves are ashen, they need more light; if they are yellow, they are 'sunburnt'; bolting stems mean too much heat; and cracks mean inconsistent watering in the sun. I keep records of these observations in my garden journal. Move the plant as soon as you see any of the signs.

Seasonal Remains. Crops All The Year Round. Spring sown where they get full sun up to noon, summer crops that require shade in the afternoon, fall, morning sun, cross in varieties now, weak, winter greens require only the lowest I of a warmer, less sunny light! I changed the place of all my crops in the little garden! The simplest item of my practice doubles my supply!
