Different types/varieties are listed below:
- White Icicle
This is very pungent, white radish that nearly measures 5 to 8 inches or 13-20cm in length.
This is round, bright red radish with a very distinctive white tip and all white inside.

Appropriately named oblong radish with very bright red on the top half and pure white on the bottom half of it and it is sweet, mild, and very delicate in flavour and texture.
Suitable Soil for Growing Radish in Greenhouse
Radishes survive well in loose, well-drained soil that is very rich in organic matter. It will be very helpful if the soil has fewer or no stones at all. The optimal and ideal pH for radish-growing medium or soil should be nearly 6.5 but the plant can even stand soils with pH ranging from 6.0 to 7.0.
Keep the soil always moistened. Avoid using fresh compost and organic substances or fertilizers that are very high in nitrogen because extremely rich soil may promote lush foliage which will lose crisp and appetizing roots.

Lighting and Temperature Requirement for Growing Radish in Greenhouse
The main secret is simply obtaining adequate sunshine. Radishes do very well if they get at least six hours of full sun every day. However, they are a cool weather plant and they can even tolerate some level of shade.
Keep the temperature nearly between 10°C to 21°C most of the time. You should not pout if you want to grow radish in the heat of summer.
Radish Seed Germination Process for Growing in Greenhouse
Radish seeds are very good for around 4 years after you have purchased them. Radishes usually prefer cooler weather or climate but they can germinate in a very wide range of temperatures from 4 to 32°C. The optimal and ideal temperature range, though, is a more moderate 10 to 24°C. At these temperatures, the average period for your Radishes to pop out of the ground is nearly about 5 to 10 days, depending on the weather or climate. The soil needs to be a little moist all over the life of your Radishes. Usually, this is not a big problem as they will grow so well in the spring which is usually a damp time of year in many of the areas. The ideal and optimum weather for Radishes from seeding to harvesting is damp and is nearly about 10 to 18°C.
Planting Radishes in Greenhouse
Be sure you provide it with organic compost or aged manure into the soil, to start with.
Sow the seeds about an in. into the soil spacing them an in. aside from one another in rows that are one foot apart.
After the plants germinate, thin those therefore the plants are spaced two inches apart.
A Small Tip for Growing Radish in Greenhouse
Better ensure that the greenhouse kits that you have provided for your radishes have adequate sunlight because shade conditions will encourage the plants to produce more and more leaves and very little of the sweet edible roots.
Thinning the radish plants when they are a week old gives rise to the best roots. If they are not thinned, you are expected to end up with shrivelled, inedible, and bad roots.
Water Requirement for Growing Radish in Greenhouse
Radish plants require adequate watering meaning that the soils need to be wet always but not waterlogged. Optimally, better to provide one inch of water every week. Watering in moderation is the main key point. If your soil is extremely dry, radishes may bolt and they will become short and even too sour to taste. If excessively saturated, the roots may break and decay. Do not allow the soil to dry out quickly, and do not keep it very dirty, either.
Fertilizer Requirement for Growing Radish in Greenhouse
Radish plants like plenty of phosphorous content so if you intend to add fertilizer before sowing, better to use something like bone meal. Too much nitrogen may encourage heavy top growth and even discourages root bulbs. Use kelp meal which is loaded with micronutrients and will supply trace minerals to plants that will be consumed.
Growing Tips for Radish Plant
Consider the following five tips to get the best radishes in a greenhouse:
- When preparing the soil for radish, avoid using fresh manure and organic materials or fertilizers high in nitrogen. Overly rich soil may also encourage lush foliage at the expense of crisp and tasty roots.
- When the radish plant seedlings are nearly about two inches tall, thin the plants to three-inch spacing’s. If not thin, you are likely to end up with shrivelled and very inedible roots.
- Mulch the radish plant with compost enriched with wood ashes. This process not only keeps root maggots away but also helps the soil to retain moisture which could mean the difference between perfect and pitiful radishes.
- Water very carefully. If the soil is just too dry, radishes may bolt and become very pithy and too pungent to eat. If too wet, the roots will split and decay. Never let the soil dry out of it, but don’t keep it too mucky, either.
- Radish plants are superb companion plants, particularly when used to draw aphids, flea beetles, and even other pests away from peppers and squash plants and other vegetables.
Common Problems and General Challenges When Growing Radish in Greenhouse
Flea beetles are the most common problems with radish since they fly and bounce around them. Sprinkling insect repellents like neem won’t be an honest help. What you’ll do is canopy them with a screen or insect-proof screen.
Mulch your radish plants with fertilizer enriched with wood ashes. It keeps those annoying root maggots cornered and at an equivalent time helps your soil hold moisture that would indicate the excellence between perfect and poor radishes. Don’t plant radishes in a neighbourhood that contained Cole veggies within the last three years.
Radishes are virtually disease-free. Long radishes, however, produce black roots that make dark spots at the bottom of the roots. If this becomes a determined problem, attempt to grow simply the round radish species.
Harvesting Radish in Greenhouse
Some varieties or types of radishes mature as early as three weeks after planting. You will see a big-sized head poking out of the bottom. to reap, lift the basis off the bottom employing a fork and stop the leafy head.
If you would like larger ones, simply leave them for an additional ten days. However, don’t leave them longer than that. If you hesitate to collect them for too long, they’re going to get starchy with a hollow centre and it won’t taste good. The leaves also are good so you’ll also pick a couple to eat as they arise, but leave some for the crop. Take care because the leaves of the red and roundish radishes will normally have tiny spikes.
When they are left to mature more, they’re going to develop a scape and start flowering to make seeds. These seedpods also are yummy too! Leave the pods to dry and there you’ll have seeds for the subsequent season.
Commonly Asked Questions about Growing Radish in Greenhouse
How many radishes do I get from one plant?
One seed will produce only one radish. The good and main thing is they grow very quickly, so if you want more, just plant more seeds in the area. Before long, you will have more radishes than you know what to do with and enjoy your harvest.
How do I know when my radishes are ready to harvest?
Radishes are going to be able to harvest quite rapidly, as soon as three weeks after planting for a few varieties. For many other varieties, better to harvest when roots are approximately 1 inch in diameter at the soil surface. Pull one of them out and test it before harvesting the rest.
How many days do radishes take to grow from seed?
It takes nearly about four weeks to grow from seed.
Radishes are very easy to grow in any size of garden. They are very fast-growing and are ready to harvest in nearly about four weeks from sowing. Better to sow radish seeds every two weeks in fertile, moisture-retentive soil, throughout summer for crunchy salads. Don’t forget, there are many varieties for winter too, such as mooli.
How deep do radishes need to plant?
Plant them nearly 8 to 20 inches deep.
When growing radishes from seed, prepare garden soil or a planting bed by tilling the soil a minimum of 8 to twenty inches deep, counting on the variability you’re growing.
Why are my radishes long and very thin?
Your radishes are very long and thin due to a lack of sunlight.
If your radishes are planted in a neighbourhood with an excessive amount of shade, it’s possible that they will not be ready to produce large, fat roots thanks to the shortage of sunlight. Don’t plant radishes too on the brink of trees or other tall crops, since they have sunlight to grow properly.
Why are my radishes small?
Excess nitrogen within the soil and neutral acidity also will slow the forming of radishes. a standard explanation for radishes not growing bulbs is overcrowding. Overcrowded radishes do not have the space they have to supply fleshy bulbs, so thinning to 2 inches apart can help promote bulb formation.
Should I soak radish seeds before planting them?
To start your sprouts out, you will want to soak your seeds in a bowl of cool water for nearly 4-6 hours, or overnight, making certain that seeds are submersed and not floating on top of the water. This may soften the seed coat and promote the germination process. After soaking, thoroughly drain off all the water.
At what temperature do radishes grow best?
Radishes usually prefer very light and sandy loams with pH 6.5 – 7.0 but will tolerate a wide range of soil types. Soils with a pH below 6.5 may require more liming. Radish plants are cool-season plants, preferring temperatures between 4 to 21°C. The optimum and ideal temperature range is 16 to 19°C.
