Did you water them regularly?

I live in Hobart & have had great success with swedes & parsnips in separate beds. Can they be planted in the same bed? Your advice is greatly appreciated. Thanks.

Shouldn't be any problem.

I love swedes and they are supposed to be easy to grow, but I am struggling. Have tried over 4 seasons now and they are very small and not especially tasty. Very prone to powdery mildew. It does not seem to make any difference if i germinate in pottles or sow direct. Living in Lincoln. Soil is clay base but with good rich top layer. Using home made compost enriched with sheep pellets and blood and bone. PH 6.5 to 7 Would appreciate any advice, Thanks

Also look up an organic spray for powdery mildew, I think it is chamomile tea. Also water in the morning not late arvo.

I don't think I have ever grown them, if so about 55 years ago with my mother. From your post I would wonder if you are providing too rich a soil. A root crop (carrots, beetroot, turnips swedes etc) does not require a lot of nitrogen. If you have very leafy swedes that could be the problem. Don't go too heavy with the compost and blood and bone. Make sure you mix the compost in and give it time to break down. A compost that is more mulch than actual broken down compost will take N from the soil starving the the soil of N for your vegies. Think of crop rotation where you plant a root crop after a leaf crop.

Swedes. I planted them as seedlings in Sep/Oct. They grew ok but quite early developed flower shoots, and the roots became woody. What is the secret to avoid this? Should I plant them earlier, say July-August?

We spend 6 months in Puerto Vallarta Mexico where daily temperatures are 75 - 85 F. and almost no rain, but mild humidity. They are impossible to buy and wonder if we could grow a few for ourselves. They do not seem to import them as they do apples. We really miss them in soups and stews.
