Hi Rwh and welcome to GoY which variety did you sow?

Are there signs of deficiency, which you can look up. Also did you sow your swedes before June. Fresh farmyard manure will not help with flavour.

Thanks for your comments, the variety i grew was Marian.Thew were sown on June 3

Re Swede again.I didn't use fresh manure. As regards deficiency, some are small but most are a good size.

Okay I've been doing a bit of research... seems that if not cooked properly they can taste bitter so next question - how did you cook them?

They were boiled untill soft enough to mash.We have bought and grown swedes before this is the first time had any taste bitter.

This is really odd Rwh - that particular variety, as you may know, is meant to taste very good. Can you go back to whomever supplied the seed (not the garden centre if this is where you bought) and ask for advice.

Thanks Moon Grower,I'll get in touch with the supplyer and let you know what they say

Yes do get back to me I'm interested to know what they will say as this is a new variety

Been on to the supplier these are his words. The reason is lack of boron treat the area with borax or pbi multitonic this is mainly in Swedes.

Sounds odd to me... you said you've grown Swedes before - in that garden?

Not grown in this garden before. Been on phone to supplier he says treat now and hopefully they will be edible after a week or two.He has treated this symptom before.

Let us know if it works or doesn't!

Will do
