    not a fan of walnuts either ( and I don't drink )

  • Pineapples, cut the top off, leave it in water and plant it when it roots. There was an episode of GW where a lady demonstrated how to do it 🙂.

    Sweet potatoes if we get a nice summer.

    You can plant carrot or parsnip tops as mentioned already and they can flower and give you seed. It's worth trying because many insects love the flowers.

    Know what you mean Hostafan , celery actually makes me sneeze so it’s never got as far as my mouth .I remember years ago I was travelling home from work by bus . The lady in the next seat had 2 celery s in her shopping basket .The bus was full up so I had to remain seated where I was and just sneezed all the way home . I got some very odd looks I can tell you .So growing or even buying a celery is a definite no no for me .
  • - I chop off shop bought spring onion ends with the root on- I replant in soil and have grown with great success. To the point I've only bought the odd, additional supermarket ones when on special or its too cold to go outside to snip off my own. The snipped ones in the pot also re-grow, so almost never ending!

    - I chopped off the bottom of bok choy, sat in water and the shoots are 5cm long now.  I plan to put in soil and see how they go

  • I tried once tomato seeds from very sweet cherry tomatoes, but they didn't germinate.

    I my garden.

    I might try that with spring onions @myclayjungle. We don't buy them very often, but I think that's worth a shot.  :)
    I love roast parsnips.  :)

    I chuck any leftover veg into my roast veg soup mix. I expect even celery [and parsnips] could be disguised that way with enough spices and seasoning.  ;)
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...

    What a top tip @myclayjungle - thank you. I'd never thought of growing spring onions like that but I guess it's just a bigger form of growing chives.

    Never understood why gardening columns etc suggest growing spring onions as a quick and easy catch crop. They're not easy at all if you start them from seed.

    Celery (especially the heart) 😋🥰

    Parsnips - a real 'meh' veg! too sweet for me.

    I find onions one of the easier to grow from seed,  it’s the plaiting after I can’t do very well. 
    Gardening on the wild, windy west side of Dartmoor. 

  • I have germinated mango stones, avocado stones, loquats, lychees and pomegranates. Pineapple tops grow fairly easily but no one warned me how much room they need width wise once they get going.
    One year I had some tomatoes which when I cut them open had seeds already sprouting, I binned them as I have no problem growing them from fresh seeds.
    None of my efforts produced plants able to fruit, due to lack of heat and light at the required times in their life cycles. I always started my experiments with fresh stones, pips or seed.
    My grandmother grew a date palm from a stone and a wonderful peach tree which eventually fruited with glorious huge almost white flesh and delicious flavour.
    That was before the days of F1 hybrids etc.
