Kohlrabi

Brassica oleracea var. gongylodes

If cabbage is familiar and simple, then kohlrabi is the same, but sweeter, more tender and much more spectacular. Bright purple stem with green leaves and purple veins. The taste is like the core of a young kohlrabi head: juicy, sweet, without any hint of cabbage sharpness. A culture that even children enjoy eating.

Ripening and optimal harvest time

6–8 daysOptimally

The cotyledons open, the taste is the most tender and sweetest.

9–11 daysAcceptable

Optimum: the stem has gained color, the cotyledons are bright, crunch and juiciness are at their peak.

12+ daysOverripe

The first real leaf appears, the stem becomes woody from below, the taste becomes "cabbage-like".

Why flavor may vary batch to batch

The purple color of the stem and veins - anthocyanins - are synthesized under the influence of bright lighting. With powerful phytolamps and a cool temperature (+16...+20°C), the color is rich and bright. In low light or warm (+24°C and above) — pale pink or almost green. This is a purely visual difference, it does not affect the taste.

How to use

Kohlrabi is a great culinary accent. Add fresh at the end of cooking or directly on the plate.

Coleslaw of a new generation

kohlrabi + carrot + apple + yogurt dressing — a sweeter and fresher version of the classic salad

Bowl with egg dishes

poached eggs or scramble + kohlrabi + avocado - a purple stem on a yellow background looks impressive

Tuna or chicken sandwich

a layer of kohlrabi between the toast and the filling is crunchy without too much flavor

Smoothies

banana + apple + a handful of kohlrabi - sweet greens are not felt, but enrich the drink

Side dish for fish

kohlrabi + olive oil + salt + lemon. Simple and delicate

Salad with orange

kohlrabi + orange segments + pine nuts + honey-mustard dressing — purple-orange contrast

Perfect pairings

With milk dressings

The sweetness of the greens goes well with the light acidity of the sour milk sauce

Sour creamYogurtBut softer and fresher
With white fish

An alternative to lemon or cucumber as a fresh accent

The sweet taste of kohlrabi does not spoil fruit cocktails - it "hides" and gives a vitamin charge without a vegetable aftertaste

SmoothiesGreen juiceBerry cocktail
What NOT to do
  • Do not subject to heat treatment - the crunch disappears from heating and the smell of cabbage appears
  • Do not combine with very sharp flavors (garlic, hot paprika) - the delicate sweet taste of kohlrabi is simply lost
  • Do not cut after the appearance of a real leaf - the stem is already woody and the taste changes noticeably

How to store

Kohlrabi keeps longer than most microgreens. Follow simple rules to keep it fresh for up to 14 days.

In tray (growing)
up to 14 days

Refrigerator +4...+6°C. Kohlrabi is one of the hardiest microcultures. The term in the tray is up to 14 days.

Cut
up to 14 days

Place in an open container or plate, cover with a damp paper towel. Don't seal — without air, greens yellow faster.

Main rule

Don't wash until ready to eat. Wet greens spoil much faster. Rinse just before serving.

Pro tip: Kohlrabi is one of the easiest microcultures. Great for selling cut with a week or two of stock.

Benefits & composition

Kohlrabi is valued for its rich vitamin-mineral composition and bioactive compounds typical of microgreens.

Like most microgreens, kohlrabi contains a concentrated amount of nutrients relative to its weight — many times more than the mature plant.

Key nutrients (per 100 g fresh weight)
Protein2.8 g — building material for cells
Calories~30 kcal
VitaminsC, K, A
MineralsCalcium, Potassium, Magnesium
Usage notes
  • If you have a sensitive stomach or are prone to discomfort from raw vegetables, start with a small amount; cruciferous vegetables in large portions can sometimes increase discomfort
  • People taking blood thinners — because of the vitamin K content, should stick to a moderate amount and consult a doctor
  • With diseases of the thyroid gland - cruciferous vegetables in large quantities in raw form can be relevant; for specific purposes, check with your doctor

Vitamin C

is contained in kohlrabi in a noticeable concentration - young sprouts are traditionally richer in this vitamin than an adult vegetable. A vegetable source of vitamin C for those looking for variety in their diet.

Anthocyanins

in the purple variety, there are pigments that give the stem a characteristic color and are traditionally considered antioxidants.

Glucosinolates

a class of antioxidants specific to cruciferous plants. The concentration in young sprouts is higher than in an adult plant.

Vitamin K

is found in leafy greens and is traditionally associated with the support of blood vessels and bone tissue.

Step-by-step guide

01

Seed preparation

The seeds are small, without soaking. Sow dry.

The most popular variety for microgreens — Violet Vienna (purple stem, green cotyledons with purple veins). Green varieties of kohlrabi give a less expressive color - for commercial cultivation, the purple variety is much more interesting.

02

Sowing

  1. Moisten the substrate evenly
  2. Sprinkle 2 g seeds evenly - with a small rate, each seed is important
  3. Spray liberally from a spray bottle
  4. Press lightly with the palm of your hand

The norm of 2 g gives the plants more space than the standard 4-5 g for cabbages. This is fundamental: with denser sowing, the stems compete for light and remain thin and pale. It is the sparse sowing and powerful lighting that give the thick, bright purple stem, for which you pay more.

03

Clamp — 1–2 kg

Clamping is mandatory - it helps the root to grow quickly into the substrate and ensures straight vertical stems. Without clamping, the stairs "dance" and fall.

  • Empty tray on top + 1–2 kg evenly
  • Keep the entire period of darkness
04

Darkness (Blackout) — 3–4 days

What is normal:

  • Thick white fluff on the roots for 2-3 days — root hairs, not mold. They are especially abundant in kohlrabi. They dry up in the light and disappear
  • Friendly level stairs already on the 2nd day

What is NOT normal:

  • Black or green mold with an unpleasant smell on the stems is real mold, not root fluff
  • Decay of the base of the stem → waterlogging. Reduce watering, ventilate

Watering: usually not needed. When drying - the lower one through the pallet.

05

Vegetation in the light — 5–7 days

Lighting is a key parameter for color:

  • LED phytolamps: 16–18 hours a day
  • The brighter the light, the more intense the purple color
  • In low light, the stem remains pale pink or green — the marketable appearance is lost

Temperature: +18...+20°C is optimal for saturated color. At higher temperatures (+24°C and above), anthocyanins are synthesized less, the color fades.

Watering: 1 time a day, lower through the pallet. Kohlrabi likes moisture, but not "swamp" — it is prone to black leg when overwatered, especially on a coconut substrate.

Ventilation: daily ventilation. As with all crucifers in dense planting, there is a risk of mold in stagnant air.

Do you want the most saturated purple? 2 days before collection, move the tray to a cooler place (+14...+16°C). Temperature stress increases anthocyanin synthesis—the same trick as for Red Russian kale.

Watering

  • Water it 1-2 times a day (in the morning - necessarily, in the evening - if necessary)
  • Lower watering is better; the upper is permissible carefully
  • Kohlrabi grows more slowly than broccoli - water sparingly
  • A sign of lack: the leaves curl slightly and fade → pour through the pan
Kohlrabi is a more patient crop than broccoli. But do not let the substrate dry out for more than a day.

Storage

Uncut in tray Fridge +4...+6°C up to 3 weeks
Cut in container Refrigerator up to 7 days
Room temperature 1–2 days

Harvest

When to cut
  • Cotyledons are fully opened and bright
  • The stem has acquired a purple color and looks juicy
  • Height 6–8 cm
How to cut

Under the root - the stem is the tastiest and most spectacular part, cut as low as possible.

Sink

Immediately before use or sale.

Seasonal adjustments

Summer / warm room
+24°C and above
  • Color: at a temperature above +24°C, anthocyanins are synthesized more weakly — the purple shade will be paler
  • Height: accelerates, the cycle can be shortened by 1-2 days - check readiness more often
  • Collection: cut a little earlier, while the stem is still juicy
  • Ventilation: in the heat, a dense carpet gets moldy faster - increase ventilation
  • Watering: water less often, in the evening - the moist substrate overheats in the heat
Winter / cold room
+16°C and below
  • Color: the best season for kohlrabi — anthocyanins are maximally saturated when cool
  • Cycle: can be extended by 1-2 days - do not rush to cut
  • Temperature reception: 2 days before harvesting, keep at +14...+16°C — gives the brightest purple color
Water pH and EC
Acidity
6.0–6.8
pH — optimal range

Optimum range for kohlrabi: 6.0–6.8. Like cabbage, kohlrabi prefers a slightly acidic environment. At a pH above 7.2, the assimilation of trace elements may decrease. Normal tap water is fine.

Electrical conductivity
1.2–1.8
EC (mS/cm) — optimum

Optimal range: 1.2–1.8 mS/cm. Kohlrabi is moderately demanding on nutrition. In substrate cultivation, EC is not critical. With hydroponics, follow the range for even growth.

Experienced grower tips

The purple stem is the main selling point

Show a live tray or photo - the bright purple color sells itself without any description. Invest in lighting and cool temperatures — it pays off.

Temperature stress 2 days before harvesting

+14...+16°C for the final 2 days — noticeably strengthens the color. No special equipment is required: simply move the tray to the floor or to a cooler part of the room.

Kohlrabi + broccoli is a classic premium mix

The same agricultural technology, readiness at the same time. The purple stalk of kohlrabi and green broccoli look spectacular together and complement each other in composition.

Cut to the root

The stem is the most valuable part of kohlrabi. The cut as low as possible gives more product and preserves all the decorative and taste effect.

Agronomy notes and common mistakes
Agronomy specifics
  • Sowing: No soaking. High density. Kohlrabi germinates evenly and gives a dense carpet.
  • Clamp: Light (0.5 kg), 1 day.
  • Temperature: +16...+20°C. Cool conditions give more tender and tasty microgreens.
  • Watering: 1-2 times a day. Similar to broccoli in terms of water needs.
  • Ventilation: Important: crucifers without ventilation are prone to fungal lesions.
Common mistakes and solutions
  • Weak lighting → Pale pink or green stem instead of purple → Powerful phytolamps, maximum intensity
  • Cultivation at +24°C and above → Pale color, thin stem → Keep at +18...+20°C
  • The sowing rate is above 2 g → Thin pale stems due to competition → Strictly 2 g space for each plant
  • Overflow → Black leg, especially on coconut → Moderate bottom watering, good ventilation
  • Panic due to root fluff → They throw out the tray, considering it to be mold → White fluff is the norm for cruciferous plants
  • Late cut → The stem becomes woody, a real leaf appears → Cut when the cotyledons are open and the color is bright
