Combating club root
« on: February 03, 2015, 21:12 »
I have club root on my plot. One of the old guys on the site told me the best way to beat it is to first dig a hole for the seedling. Cover the surface with a layer of lime. Fill the hole with shop bought compost. Plant the seedling and then finally a sprinkling of chicken pellets around the seedling. I have had some mixed results using this method but have read somewhere adding lime & fertiliser at the same time is counter productive. Can anyone shed some light on this? Does anyone have any other ways to combat the dreaded club root?
Happiness is not something ready made. It comes from your own actions.

I use club root resistant varieties and grow them in pots.
Try and use a 6" pot and let  the plant get a good root system prior to planting.
I would do exactly as you have done but on the chicken manure pellets a couple of weeks after planting.

I was told, to make sure you start with a good healthy well-grown plant, dust the roots with lime and plant as normal.  Not sure about fertilizer and lime, I have heard that too, but never seen any evidence.

Manure and lime react together chemically, cancelling each other out!
It's best to leave a few weeks between application of each 😄

club root is a micro organism that thrives in acid soil.
What you are doing here is providing a pocket of clean soil/ compost so the plant can get as bigger
root system as possible before coming into contact with infected soil.
I dig out a hole about 12" square and dust with lime.
The other posters are correct about mixing lime and manure, but in this case you are using the lime as
a barrier to slow down the spread of club root into your fresh soil/ compost.
My last plot had club root and by
Using club root resistant varieties growing them in pots and potting on until plants were in a 6 " pot.
Taking out at least a 12" square hole and dusting with lime.
Fill the hole with bought in compost or soil and plant out your plants.
I put chicken manure pellets close to base of the plants not near the lime barrier.
I know it is expensive with this amount of fresh compost but it does work.
As a yorkshire man I mix in any old grow bag compost with a handful of blood fish and bone to a 2 gallon bucket( provided it as been nowhere near the affected soil ) and use this 50/50 with new stuff.

A raised bed with new soil and use of uncontaminated plant stock is popular up here.

I too have this problem. Clean soil is essential. I grow my plants in 5" pots and transplant into a limed hole. Once the roots get into the contaminated soil it has club root but not enough to affect the plant.
This year I have a cunning plan. Many of the roadside verges have mole hills. I shall collect this soil and use it to transplant some of the brassicas into larger pots which I will sink into the allotment. Worth a try.

Thanks all. So the old guy was right! Thanks for the explanation re lime and fertiliser. I think I need to make sure the seedlings are well established in pots before planting.
