Do radish seeds need darkness to germinate?
Radish seeds planted on wet filter paper and exposed to light will germinate and the seedlings will become larger and greener than those from radish seeds planted without exposure to light. Justification/Rationale: Radish seeds are embryonic plants, which require sunlight in order to obtain energy using photosynthesis. Radish plants grown too close together can lead to big tops and no roots. When each radish top gets so large, they compete for resources like sunlight, water, and nutrients. Big leafy plants can start shading one another out. Thin radishes to at least 2 inches apart.Remove any weeds growing around your radishes and keep the soil moist.

Too much shade will force the plant to produce more leaves than harvestable roots. Radishes are cool-season crops that do not grow well in hot, dry climates.
Do I soak radish seeds before planting?
I start off by soaking my radish seeds for several hours or as long as overnight. The hard seed coat softens and germination happens faster. Sow radish seeds outdoors with other cool season crops or as soon as the soil can be worked in spring. Radishes have really great germination rates and will sprout quickly. From the day you sow your seeds to the date of harvest is typically about 4-5 weeks.
How often do I water radish seeds?
Radishes need consistent moisture to grow properly, so it’s important to keep the soil evenly moist. Water them regularly, but avoid overwatering, which can cause the roots to rot. Try watering every few days or when the top of the soil feels dry. Problems can include: Roots fail to swell – this can happen for various reasons, including dry conditions, heat and overcrowding. Salad radishes grow best in mild spring weather – in summer they need regular watering, especially in hot, dry spells.Radish Light & Temperature Requirements Radishes grow optimally in full sun conditions, but they can thrive in partial shade as well. Too much shade will force the plant to produce more leaves than harvestable roots.
