Kohlrabi is another name for our not-so-popular Knolkhol. It belongs to the same family as Cabbage and Cauliflower(Brassicaceae). The Whole plant is edible however, it is mostly used for its bulged swollen stem. It can be eaten raw as well as cooked. Though it prefers a cold weather, it does moderately well for our Bangalore weather.
Knolkhol makes a good candidate for a kitchen garden because of its quick maturity. It comes to harvest in just about 50 days. Another interesting part is that it comes in different colors :D.
You get them in White, Green and Violet/Purple.
Growing Knolkhol is also very easy. Buy good quality seeds to begin with. You can get them Lalbagh Nurserymen Co-op.
Take seed starting mix(cocopeat) and moisten it.
Sow the seeds, 1/4 inch deep in the media.The media you see in the pic below is vermiculite. Cocopeat/perlite/sand or a combination of those will do as well.
The seeds germinate in about 4 days.
They were transplanted into trays (6” deep) when they showed two true leaves.
Below is the picture of those plants a month later. Look at the growth. I planted about 6 seedlings per tray. From the right, you see Amaranthus, Knolkhol and coriander(+assorted greens).
Vigorous growth can be seen. At this point, the stem has started to swell and is lemon sized.
Knolkhol just started to form.
I removed few leaves from the bottom as it started touch the media.
In about ~50 days time, the knolkhols are ready for harvest. Its better to harvest them little before they are completely mature.
I harvested mine and here are the pics. Sorry about the shake in the pic. It was taken at night.
This variety is called Purple Vienna. There is white vienna too. What are you waiting for? Go buy a seed packet and start sowing them..
