We planted radishes right in the ground inside our greenhouse this winter so they are already ready to harvest early spring! This year we planted Pearl Radishes which are white in color and have a more mild flavor. I admit I think the greenhouse got too hot right at the last minute which could have caused the woodiness to some of the larger roots.
When to plant…
Radishes are a cool weather crop and best to grow in the Spring or Fall. Plant radishes about 2-3″ apart to avoid crowding. Radishes are not a big fan of fertilizer as it makes the tops grow larger instead of focusing on the root. They also need nice moist soil. If the radishes take too long to grow due to hot weather or dry soil, they can get hard and woody.
Length to Mature… 3-4 weeks
When to harvest…
You will want to harvest them before they get too big and turn bitter as they tend to get spongy. Normally, before they are 1″ in diameter. When you pull them out of the ground, be careful not to disturb the small ones around them as you thin the crop down, that way you can continue to enjoy the radishes throughout the season as they grow.
How to select and store…
Radishes can come in a variety of colors: pink, red, purple, violet, green, black and white. Radish tops should be bright green and not at all wilted. The roots should be brightly colored and free from cracks. Squeeze them to make sure they are not hollow or soft in the center.
Radishes can last in your fridge for 1-2 weeks and are best if you cut the tops off of them before storing. The tops should be used within 2-3 days.
How to preserve it…
Radish Relish can be sealed and stored for up to 1 year.
Fun Tip…
Don’t throw the tops out! The radish leaves are delicious and nutritious.
