Green Meat

Radish

45d to harvest

Sink your teeth into Green Meat’s jewel-toned interior—crisp, juicy flesh with a cool, clean bite and a pleasantly mild radish snap. The exterior forms a round, watermelon-style radish with a fresh green skin that gives way to a striking green core, tender and succulent at maturity. Grow it for show-stopping freshness in salads and platters, or slice it for vibrant color in quick pickles and bright, zesty sauces.

Frequently Asked Questions

What’s the most common problem for Raphanus sativus (radish) and how do I fix it?

Flea beetles commonly chew holes in radish leaves and can stunt growth. Use row cover after sowing until plants are established, and if needed apply a labeled insecticidal soap to the foliage in the evening. If you see fungal leaf spots or mildew, remove affected leaves and water at soil level to keep the foliage dry.

How often should I water Raphanus sativus during the main growing phase?

During active growth (roughly the first 3–4 weeks), keep the bed consistently moist with about 1 inch of water per week, split into 2–3 waterings if it’s hot or windy. Let the top 1/2 inch of soil dry slightly between waterings, but don’t let it fully dry out because radishes get woody and hot-tasting when they’re stressed.

How can I tell when my radishes (Raphanus sativus) are ready to harvest?

Start checking around day 35 and harvest by day 45 when the roots fill out and the shoulders are clearly visible at the soil surface. Most radishes are ready when you can feel firm, crisp roots about the expected size for your seed packet; if you wait longer, they often become pithy and can bolt. Pull one sample to confirm—if it’s tender and crisp, harvest the rest right away.
