Radish take 5-10 days to germinate and are usually ready to harvest 3 to 5 weeks after planting.
Growing radishes in grow bags can be a convenient and space-efficient way to cultivate these quick-growing vegetables. Here's a step-by-step guide to help you with the process:
1. Choose the Right Grow Bag:
Select a grow bag that is at least 8-12 inches deep and has good drainage. Fabric bags are preferable as they allow for proper aeration and prevent overwatering.
2. Select Radish Varieties:
Choose radish varieties that are suitable for container gardening. Most radish varieties work well in grow bags.
3. Soil Mix:
Use a well-draining potting mix with a balanced blend of organic matter. Radishes prefer loose, well-draining soil to develop properly.
4. Planting:
Sow radish seeds directly into the grow bag. Follow the recommended spacing on the seed packet, usually about 1-2 inches apart. Plant the seeds at a depth of around 1/2 inch.
5. Watering:
Keep the soil consistently moist, but not waterlogged. Radishes prefer even moisture, and consistent watering helps prevent cracking or tough roots.
6. Sunlight:
Radishes require at least 6 hours of sunlight per day. Place the grow bags in a location where they receive adequate sunlight.
7. Fertilizing:
Use a balanced fertilizer during planting, and consider a light application of fertilizer when the plants are a few inches tall. Follow the package instructions for the specific fertilizer you choose.
8. Thinning:
Once the radish seedlings are a few inches tall, thin them to the recommended spacing on the seed packet. This ensures that each radish has enough space to develop properly.
9. Harvesting:
Radishes typically mature within 3-4 weeks, but check the seed packet for the specific variety's expected harvest time. Harvest when the radishes are firm and the tops have reached the desired size.
10. Succession Planting:
Consider planting radishes in succession every 2-3 weeks for a continuous harvest throughout the growing season.
Tips:
Be mindful of the water needs, as containers can dry out more quickly than garden beds.
Watch out for pests, and take appropriate measures if you notice any issues.
If temperatures are high, providing some shade during the hottest parts of the day can prevent the soil from drying out too quickly.
Companion Plants:
Companion planting involves growing different plants together that can benefit each other in various ways, such as deterring pests, improving soil fertility, or enhancing growth. When it comes to radishes, there are several companion plants that can be beneficial. Here are some options:
Lettuce: Radishes and lettuce make good companions. Radishes can help deter pests like cucumber beetles that may otherwise bother lettuce. Additionally, radishes have a shorter growing season, so they can be harvested before lettuce needs more space.
Carrots: Radishes are often interplanted with carrots. Radishes can help break up the soil, making it easier for carrots to push through. Carrots take longer to germinate and grow, so the radishes can be harvested before the carrots need the space.
Spinach: Similar to lettuce, spinach can benefit from being planted alongside radishes. Radishes can help deter pests that may affect spinach.
Nasturtiums: Nasturtiums are known for repelling pests like aphids and beetles. Planting them near radishes can help protect radishes from these pests.
Peas: Radishes can provide a bit of shade to peas as they start to grow. Peas, in turn, can benefit radishes by fixing nitrogen in the soil, which is a nutrient that radishes appreciate.
Beans: Like peas, beans are nitrogen-fixing plants. They can help improve soil fertility, benefiting radishes planted nearby.
Chervil: Chervil is a herb that can improve the flavor of radishes and may also help repel pests.
Garlic and Onions: These pungent plants can help deter pests, and some gardeners believe they enhance the flavor of radishes.
Mint: Planting mint around radishes can help deter pests, but be cautious with mint as it can be invasive. Consider planting it in a container near the radish patch.
Marigolds: Marigolds are known for repelling nematodes and some other pests. Planting them near radishes can help protect the radish crop.
Radishes do not grow well with melons, pumpkin, corn, sunflowers, potatoes or turnips.
How do I fertilize my Radish?
One important thing about radish that you should know is that it does not need heavy fertilization in order for it to grow and produce well. As a matter of fact, it is usually enough to add nutrients to the soil prior to the actual planting if you wish to feed these vegetables known for their rapid growth and development.
What bugs attack Radish and what gets rid of them?
-
The soft-bodied adults put their needle-like mouths into plant tissue and suck the plant’s juices. While they are taking nutrients from the plant, these pests also insert toxins that affect the plant’s growth.
Aphids can be controlled with an insecticidal soap. Always spray plants in the early evening to reduce the chance of damage. Pay special attention to the lower leaf because that is where they usually are located.
-
These little beetles have shiny coats with huge rear legs, which they use to propel themselves up into the air. They can be black, brown, or a mix of colors.
Flea beetles can be naturally controlled using rubbing alcohol. Dilute it with water in a 2:5 ratio. 2 parts alcohol to 5 parts water should do the trick. This should be enough to kill any flea beetles hiding on your plant.
-
“Cutworm” is the name used for the larvae of a number of moth species.
Hand pick cutworms off the plants and surround the plants with diatomaceous earth.
What soil pH is best for Radish?
Any well-drained, slightly acidic to neutral soil with pH 6 to 7 will do for radishes, as long as the soil is not compacted.
How do you store Radish?
In dirt: If you have a root cellar or just a cool room in your basement, you can keep radishes there, covered in soil or damp sand to mimic their natural environment. Radishes stored this way can last three months.
In cold water: Whole radishes can last for over a week in a jar of cold water. Simply wash these veggies, cut off the radish greens and root ends, and place them in a tightly sealed jar filled with water. They should last up to two weeks.
Frozen: Quarter or slice radishes and blanch them by submerging them in boiling water and then a large bowl of ice water for about two minutes each. Pat them dry with a paper towel to remove excess moisture. Then place the cut radishes into freezer bags for long-term storage. Be sure to squeeze excess air out of the plastic bag.
Pickled: Pickled radishes can last up to six months in a refrigerated canning jar. When pickling radishes, use a formula that combines a half-pound of radishes with a half-cup of sugar, a half-cup of white vinegar, a quarter-cup of water, and a teaspoon of salt.
