Last year at Charles’s suggestion I started beetroot and pak choi in modules, with considerable success. However the trays were very flimsy and small. So I bought some rootrainers, the kind that split open, the quality is awful, the thinnest plastic imaginable. This year I bought some larger root trainers fron nutleys. Has anyone tried these? They seem quite decent. I do wonder if carrots could be started in them, though I am not sure why. I tried some carrots in the rootrainers, they grew but were small.11th February 2016 at 12:17 pm #33158
Carrots and Parsnip should be sown direct rather than in module trays or root trainers as they do not like root disturbance.
A great alternative I have tried in the past, is to sow into toilet rolls and then plant out seedlings and rolls into their final positions. The only problem with this method is getting enough rolls.

Hello Dan, yes I know carrots and parsnips, and other long rooted vegetables, do not like being transplanted, the large root trainers are much larger, so I may try. The carrots will be transplanted once a decent root system has established, and bound togther the soil. I’m not convinced it iis worth it except perhaps for some early ones raised initially in a coldframe, and not in my cold clay soil.12th February 2016 at 8:04 am #33166
I cannot sow anything directly as the slugs demolish anything small and new. Therefore, I start carrots and parsnips in guttering, if one takes care to slide them into their final growing spot before they get too big they do absolutely fine.12th February 2016 at 8:39 am #33168
Hi Leif. I’ve bought the Haxnicks deep rootrainers and find them great for seed such as beans and peas. Easy to fill and I’ve had no trouble extracting plants once ready to go out. Should last many years too. Not sure I’d bother with carrots and parsnips in them but, if you have mollusc issues like Hawfinch, I wouldn’t rule the idea out.
Nearly time to step up to the start line here in N.Yorks 🙂12th February 2016 at 9:29 am #33172
I started using modules last year like you and I successfully used them for:
Kale, Rocket, Spinach, Pak Choi, Chard (over-wintered and summer); Lettuce;
Beetroot (clumps); Onions (singles and clumps); Shallot (singles);
Pea (maincrop); Mange Tout; Runner Bean; Climbing Bean;
Autumn Cabbage; Brussels Sprout; Spring Cabbage; Swede;
If you wanted to do carrot or parsnip, have you thought of using a 35 litre pot? I normally use them for growing potatoes or tomatoes, but they would easily be deep enough for you to be able to extract seedlings prior to them getting too big. I’ve successfully transplanted young carrots from rows where uneven germination took place, so I suspect that transplantation per se isn’t the issue, more root forking.
If you had soil deep enough like in a 35 litre pot, perhaps that wouldn’t be an issue either? I guess ultimately it depends on how many you want to transplant……12th February 2016 at 9:48 am #33173
Parsnips certainly do transplant ok. Neighbors on the allotments regularly transplant the thinning a and so long as they are kept moist they do surprisingly well.
Waste not want not and all that!13th February 2016 at 10:14 am #33176
Thanks all, lots of useful information there. I use slug pellets, the non organic kind, I know they are frowned upon, but the organic ones dissolve too quickly, and from what I can tell if you spread them thinly, they are not a danger to wildlife. Also, I have found that a coldframe helps keep out slugs, hence raising seedlings in modules in a coldframe protects them from birds, frost, and slugs.
Does anyone start leeks in root trainers, or small pots, if so how many per pot? I normally sow leeks direct, they grow well, and require almost no care.13th February 2016 at 12:02 pm #33177
I have used toilet roll holders for years , and more so now I am a no dig fan ,I ask my friends and
neighbours to collect them. I also collect kitchen towel holders cut them into three and use them
for my beetroot .13th February 2016 at 7:52 pm #33182
Last yearI bought the Nutleys 12cm deep root trainers from Amazon and used them to grow some sweet peas. They survived their first year intact and I had no problems using them.
Does anyone have experience of using them for broad beans? Will they be deep enough?
What depth should they be sown in 12cm root trainers?
(That’s 4 and a quarter inches…)14th February 2016 at 8:19 am #33186
For broad beans I use 3inch (7.5cm) deep trays and they transplant fine, the tap root a little squashed in there but growth is good after planting.16th February 2016 at 10:12 am #33238
I use deep pots (Long Toms I think they are called) for broad beans, French beans, peas and sweet peas. The depth – 7 ” allows for good long root growth. I cover the moist surface of the compost with the beans/peas which have been soaked over night so there are about 12 to 15 to a pot. The trick is to catch them for transplanting before the longroots have knitted themselves together. I then dib them into the earth. Always successful and saves a huge amount of space in my limited starting off area.
