You are quite right there Judith I worked on the farms in Scotland and you never lifted turnips till they had the frost on them, that`s what gives them the sweetness. I have no idea why they don``t leave them in the ground longer until they grow bigger as you said like a bowling ball. I have bought some seeds to try and grow them here in Melbourne but I think I have left it a bit too late this year as the cold weather is here already, but I will definitely plant them next year in time for winter.

We planted swede seed in trays 3 weeks ago in potting mix and had 2 seeds germinate. We kept them moist and they were in dappled shade - what did we do wrong?

Swede are to be sown direct into the soil just like carrots. They don't like to be transplanted.

Plant your swedes From seedlings april. If leggy when germinated. Plant seedlings deeper up to first leaf join.

Hi i've read all over the place that you can regrow Swedes from the Top (Kitchen Scraps) i've just tried this on my laundry windowsill in water - it has started to grow long thin roots & a few (3-4) shoots off the top.. Now i'm wondering how to transplant it without causing it to rot or something?? Also Will it regrow to produce another Swede or few?? Do i separate the shoots on top or replant the top whole?? Thanks, Sam

Dig a hole about 5 cm deeper that the roots. Bed in your plant using a good potting mix. It will 'take' in about 2 weeks and start to grow. After 3 weeks fertilize with half strength liquid fertilizer such as Miracle-Gro. Don't fertilize again if your soil is good.

I have grown some swedes in Dubbo good tops and no actual swede developed. what would cause that.? the soil was well fertilized with sheep manure.

Root crops such as swedes, carrots, etc, do not need a lot of nitrogen; which would be present in the manure. Nitrogen in root crops causes excessive top growth at the expense of the roots. After you have freshly manured your soil it is better to start off with a leaf crop such as lettuce, cabbge, etc. Follow this with a fruiting crop such as tomatoes, beans, zucchini, etc. the soil will then be ideal for root crops such as swedes, carrots, parsnip, etc. If that is the problem; all is not lost, look after them and you will get some sort of root and the tops can be used in soup or stir fries. Trust this helps

The swede is bitter when it is cooked. I thought it is lacking something in the soil. What am I doing wrong.
