Hi, I have just started my garden and as I prepared the soil I found ants everywhere, but I read somewhere that putting powdered cinnamon around the garden edge would stop the ants as they apparently don't like the sticky powder as it sticks to their legs. I did and it has worked so far. Have to retouch if I overwater the area, but I'm happier without green ant bites.... The joy of my garden is the growing and reaping the rewards of fresh veggies and herbs. Because I do sometimes wonder by the time we use all our fertilisers....I think the cost is a bit high...

Gooday , do you need to hill them or do they produce above ground? most pics i have seen are above ground ,is this right ?

The stem swells just above the ground. No need to hill them.

Yes above the ground in garden beds

Kohlrabi is botanically the same plant as cabbage. The stalks and leaves can be used in stir fries, soups and coleslaw making it very versatile.

Hello Noel, Kohlrabi is a swollen stem, not a root, tuber or bulb and it forms above the ground. To achieve good results ensure watering is consistent to avoid stringiness or bitterness. Trust this helps.
