How long does it take for radish microgreens to grow?

Radish microgreens typically take around 7-10 days to grow from seed to harvest, depending on factors like temperature, humidity, and light exposure. Make sure to provide them with the appropriate growing conditions for the best results.

How tall should radish microgreens be to harvest?

When it's time to harvest, radish microgreens should be about 2-3 inches (5-7.5 cm) tall. Look for the first set of "true leaves" starting to develop – these are the leaves that come after the initial 2 leaves, called cotyledons. You’ll start to see the first true leaf start to sprout in between the cotyledons. This is an indicator that your radish microgreens are at their peak for flavor and nutritional value. If your microgreens have a bitter flavor, then you know you harvested them too late.

Can you wait too long to harvest microgreens?

Yes, waiting too long to harvest your microgreens can impact their taste, texture, and nutritional value. Ideally, you should harvest them when they reach the desired height and their true leaves start to develop, as mentioned earlier.

What happens if you wait too long to harvest radish microgreens?

Radish Microgreens Appearance and Signs of Readiness

What do radish microgreens look like when ready to harvest?

When radish microgreens are ready to harvest, they'll typically be about 2-4 inches tall with small, vibrant green leaves and a tender stem. The first set of leaves, known as cotyledons, will be fully developed, and the second set of true leaves may be starting to emerge. The microgreens will have a strong, upright growth habit and appear healthy and vigorous.

Why are my radish microgreens falling over?

Radish microgreens may fall over due to a few reasons:

    If your microgreens aren't receiving enough light, they may become leggy and weak, causing them to fall over. Make sure they are placed near a bright window or under a grow light for the appropriate duration.
    Planting seeds too close together can lead to overcrowded conditions, limiting air circulation and causing microgreens to compete for resources, making them weak and prone to falling over. To avoid this, ensure seeds are spaced adequately when planting.
    Overwatering your microgreens can lead to weak root systems and cause them to fall over. Make sure you are watering appropriately, keeping the soil moist but not waterlogged.

What is the white fuzz on radish microgreens?

The white fuzz on radish microgreens is often mistaken for mold, but it's usually harmless root hairs. Root hairs help the plant absorb water and nutrients from the soil. However, if you notice a musty odor or the fuzz appears in patches on the leaves or stems, it could be mold. To prevent mold, ensure proper air circulation, avoid overwatering, and maintain a clean growing environment. If mold is present, discard the affected microgreens and sanitize your growing equipment before planting again.
