Kohlrabi in Pots

In this video I'll show you step-by-step how to sow, pot, water and harvest kohlrabi right on your balcony, and I’ll reveal the one simple size rule that stops the bulbs from turning woody and bitter, so you can enjoy fresh, crisp vegetables all season.

When to sow

Think about it: kohlrabi loves cool, steady weather, so you’ll sow it from October to December on the plains, or from September to January if you’re in Karachi’s milder climate. Stagger the seedings every three weeks and you’ll have a steady supply, and you avoid the heat that makes the bulbs bitter or the freeze that makes them bolt.

Pot & soil mix

Here’s the thing: pick a pot at least twelve inches wide and deep, fill it with two parts soil, one part compost and one part cocopeat or sand. Sow the seeds just a centimeter and a half deep, then thin them to fifteen centimeters apart so each bulb can swell without crowding.

Pot size

A twelve-inch pot gives you enough room for three to four kohlrabi plants, letting each root system spread and the swollen stems develop evenly. That size is the sweet spot for indoor or balcony gardening, and it keeps the soil from drying out too fast.

Watering schedule

Now, the part most people miss is watering. From October to November, give the pots a drink every two to three days, keeping the soil evenly moist but not soggy. When winter fog and frost arrive, stretch it to four or five days, then in February step back up to every two days as the sun warms.

Harvest size

The one rule to lock in flavor is to harvest when the bulb is about the size of a golf ball to a tennis ball, roughly five to seven centimeters across. Cut it at soil level then, and you’ll avoid the woody texture that sneaks in if you wait longer.

Leaves & pests

If you see yellow leaves or little holes, it’s usually just pests. Hand-pick any green caterpillars in the evening and check under leaves for eggs. A quick spray of water can wash off cabbage aphids, and a thin mesh cover keeps flea beetles at bay while the seedlings grow.

Harvest rule

So what should you do when the kohlrabi is ready? Measure with your fingers: a golf-ball-size bulb is about five to seven centimeters across. Cut it cleanly at soil level, trim the stalks, and enjoy the crisp flesh. For a steady supply, sow a few seeds every three weeks instead of a whole packet at once.

Verdict

The verdict? Worth it, as long as you can water regularly. Kohlrabi grows fast, fits in a twelve-inch pot, and gives you a clear harvest signal that makes it a perfect first brassica for beginners. If you can’t keep the soil moist, it will get woody faster than most veggies, so plan your watering.
