Which is the best way to sow my kohlrabi seeds straight into the garden or planting pots in the sun room? Thanks

It does say plant straight into the garden. A general rule I use is - if a very small/small seed use a pot or seed tray. If seed is bigger then straight into the garden. A small seed (cabbage/lettuce) takes a lot of looking after to get it established - 3-4 weeks. Things like corn/bean/pea seeds will boom. It also depends on the weather also. The hot or cool time of the year.

this is my first year growing kohlrabi, I love it, the flavor is different , but great, one thing though, ants love it to, they make holes into the plant, have to put ant dust or some thing on them, full of sugar. planted many new things this year, due to making more raised garden beds, red cabbage, Daikon, chard, Celeriac, red and brown onions, had a great season this year with snow and honey peas, many different lettuces this year great harvest, planted grafted apple tree, grafted peach and nectarine tree, nashi pears, grapes and passionfruit, why buy fruit and veg from the shop and not know how old it is or what they have done to it.

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...
