Benefits of digging to not digging.

Monday, February 8th, 2010

For a few years now I have not been seriously digging.  When I took over the bottom half there was a lot of water running on it from the springs so I had to do some serious drainage.  The best way I have found of draining the allotment is to dig down about three spits and then to add lots of brushwood, shreddings and even logs.  This seems to keep the soil open and allow water to pass through the soil without coming to the surface.  It seems to have worked very well because there is no water on the bottom half although there is a stream flowing down the trackway next to the allotment.  Since I did this last year, I found that mixing the soil seems to have increased the yield from this part of the allotment.  I had four rows of Early Onward peas that had a fairly remarkable crop.  We still have margarine tubs full of them now.

I repeated the exercise in November last year burying a rambling rose from one of the houses that back on to my allotment.  It was seriously taking over the trackway.  I cut it back and buried it so I am hoping that this will aid in the drainage too.  I did not dig a small area by the shed because there were still some of the annual flowers flowering.  Now that they have well and truely died, I will dig these in and try to raise the allotment here to the same height as the rest of this area.  I will probably use some of the brushwood and shreddings  to do this but make sure they are buried very deep down.  This is the exact place where the water was running across the allotment all of last winter.  There is absolutely no water at all this year, however I still want to raise the ground about another 30 cm. if I can.  I have to be careful not to bank up the soil onto the shed though.  It will only encourage it to rot.

I have painted the shed with Cuprinol or whatever it is called.  I didn’t buy it.  It was given to me.  Well, I have painted it on the shed about three times and I still have half a can left.  I am blowed if I am going to throw it away.  It is a nasty old chemical and would only pollute the world.  I will continue to paint the shed  until it all goes.  I may well paint the bean sticks and the poles holding up the wires for the raspberries.   I still haven’t moved the raspberries from the top half to the bottom half.  This is starting to irritate me because it is getting a little late to start moving raspberries.  I will have to do it though because I have planned to grow runner beans where the raspberries are now.  I have already moved the large water butt although in the move it developed a big crack in the bottom and is now useless.  I will use it to store things in and get another bigger one.

On the top of the allotment, I usually just hoe the few weeds off and cultivate the top couple of centimeters with a claw cultivator and then plant into that without digging.   This year though I will dig quite a lot of the allotment.  I am going to dig in the green manure and possibly add a lot of leaves or other organic matter depending on what people leave in the bins by the gate.  I hope the bloke with the shire horses brings another big load of horse manure.  No matter what is in it,  it is all grist to the mill; particularly three spits down.

So, do I do a no dig system or do I begin to double and triple dig again?  I might just run out of time and have to revert to no dig.  The brassicas  like to have a firm soil to grow in.  I think that this may help to deter the cabbage root fly ( Delia radicum ).  So I am not too worried if I cannot dig  the brassica area over.  I have not walked on it since I took the beans and the sweetpeas down last year, so the worms would have had time to soften it up a bit.  Going over it with a hoe, claw cultivator and rake will be good enough to prepare it.  I will also be liming this area I think.  It has not had lime on it for about four years now.  A good liming will help  to prevent club root (Plasmodiophora brassicae.)  I keep to a strict rotation and it has been about four years since I grew brassicas  on this part of the allotment.  Now  that I have the bottom half, I will be able to have a six year rotation.  It makes rotation much easier if each of the beds were equal in size.  This is why I am moving the slabs on the top allotment and making it exactly the same size as the other beds.  I will also relay the path to the tap, taking out the topsoil and replacing it with stones to make a soak away under the path.

This should even things up so that I do not have those irritating little areas where it is not worth planting anything.

I will  have to find somewhere good to plant my viburnum because it is just where I will be altering the path.  There are a lot of bulbs there too which will have to be moved.

This reminds me.  I need to take down the large plastic bags to put my old brassicas in to bring home and put into the green bin.  I should not have left the stumps in the ground because it encourages Plasmodiophora brassicae to spread throughout the soil.  I think that spores from this fungi can stay in the soil for a number of years and it is a devil of a job removing it from a planting area.    I have been fairly successful in keeping it off the allotment until this year.  I have found that the new soil that the council bought has club root in it.  I just hope that it does not spread through the rest of the allotment.

I don’t burn the stumps.  I really don’t think that a damp, smoky, foul smelling fire will be good enough to kill off club root spores. So taking them home to put in the green recycling bin is the best option for me.

Mixing the soil through digging seems to be effective in distributing and reestablishing nutrients from lower in the soil towards the top.  No  dig might be alright for a few years but I think that a jolly good digging once in a while would increase yields - especially after twenty eight years of continuous cultivation.

I am still getting really good crops off the allotment though so I can’t  be getting a lot wrong…

Muck spreading time.

Monday, February 16th, 2009

The council has now put a stake in the quagmire part of the allotment.  I think it is to indicate that this was one of the allotments that had the soil replaced.  They just need to look at the soil to know that.  It is yellow with large15cm stones in it.  Compared with the soil they removed as polluted, this so called top quality top soil is like my subsoil - but with stones.

I think that the stake signifies that I am about to get a load of muck delivered.  The council has said that they will dig over the allotments and take out all the stone.  I will believe that when I see it.  I hope that they dig in the muck as well.  However, anyone that tries to walk on that part of the allotment is in danger of sinking without trace…

Do I really want the hassle of draining this part of the allotment???  Not really.  On the other hand this is a substantial area of new soil that could possibly have potential if it did not have a flowing stream running over it.

To change the subject, my mate Tony with the horses and trap telephoned me at the weekend saying there was a substantial amount of well rotted horse manure ready for collection.  He also said that I could borrow his trailer to get it up to the allotment.  Therefore, I will be transporting horse manure for the rest of the week.  It is true to say that one man’s rubbish is another’s gold.  You can keep your banks and money and stocks and shares.  I will take a good load of horse muck any time.  You can’t eat money.

I will also have to take the greenhouse glass off the allotment.  Some really pleasant person has carefully smashed it up for me and left the shards all over the allotment.   So kind.  I just hope that I get it all because I really do not want to get cut by glass again.  Last time it was particularly unpleasant.  Really, I should go and get a new tetanus jab just in case.

The trouble is, if you put substantial amounts of muck on the allotment, you increase both the bad and good bacteria.  I define good and bad as those that will and will not give you nasty diseases.  They are not inherently good or bad.  They don’t sit there in the soil plotting to infect you.

But this is by the by, I am starting to clear off the old brassicas.  Believe it or not, because I can’t, after about 15 years of clubroot free growing, the allotment has got clubroot again.  Never mind.  Good hygiene, good rotation and dressings of lime usually gets rid of it.  I did get a 6foot brussel sprout this year - regardless.  However, the cabbage white stripped the leaves and it only produced tiny sprouts.  Fresh sprouts taste the same whether they are large or small so I don’t worry.  Well the old sprout plants went into the green bin to be taken away by the council.  I do not burn diseased material if I can put it into the green bin.

I have taken the hedge clippings down to the allotment.  I have also dug out several of the overgrown shrubs in the garden and taken these down too.  They will be buried at the bottom of the double digging trench.  Now some will say that woody hedge cuttings will rob the soil of nitrogen.  Admittedly the carbon to nitrogen ratio will be quite large but there is little information that I can find that indicates that; this will be substantial; will affect the vegetable plants if it is buried more than 12 inches below the surface; and that the nitrogen will not be returned to the soil once the hedge cuttings rot down.  At the moment, my jury is out but I have to say that putting woody material this far down in the soil does not seem to have affected vegetables in previous years.  You might say that the vegetables would be bigger; nevertheless I don’t really want brussel sprouts bigger than 6 foot.  I wish I had taken a picture of the big brussel now.

I am still getting veg off the allotment.  I haven’t had all the parsnips or carrots yet.  As I take out the brussel sprouts, I am gleaning all the little ones and taking them home to cook.  I am still using up both my red and white onions and the potatoes have not run out yet.  Together with the frozen peas, beans and cauliflower that is quite a substantial array of vegetables for cooking.   The winter cauliflowers look very bedraggled at the moment but I am hoping that they will perk up during the next couple of months.  I will give them all a dose of comfrey liquid during March just to give them a boost.   The garlic has not sent up any leaves yet.  Last year they were showing before Christmas.  The snow and frost has kept them tucked in the soil but the warmer weather we are getting now may make them throw up new shoots.

I need to order some more seeds and I must send off for some Sante potatoes.  I have the Kestral already.  They are beginning to sprout so need to be put out in the greenhouse where they can get lots of light.  I have bought some new raspberry canes again and hopefully this year they will take.  Last years ones were hopeless.  I think one out of ten canes sent up shoots.  Never mind.  I reckon that I had a fairly substantial harvest last year and I looking forward to the new year.

Brassicas are in now.

Monday, May 12th, 2008

I went up to the allotment after work today.  I wanted to get all the brassicas in.  Two varieties of broccoli, two of Brussel sprouts and two of winter cauliflower.  I don’t know what the cabbage is because they were some that Bill gave me.  I like freebies. 

Most of the plants were in 3″ pots so that when they were knocked out the roots would not be damaged.  Damaged roots are more susceptible to clubroot.  I put a seaweed and lime mixture in each of the holes (I forget what this stuff is called but it is a replacement for calcified seaweed) .  This is supposed to have lots of minerals in it and the brassicas seem to thrive on it.  The plants were then watered in with comfrey liquid.  This is all the nutrients that I will add to the soil for the brassicas.  Next year round about March or April I will water the cauliflowers with comfrey again. 

I have trodden on this part of the allotment quite a bit so the ground is very firm.  I like this because it means that, if there is a lot of cabbage root fly about this year, they will find it difficult to lay eggs through a compacted soil.  Secondly, a firmer soil means that the brassicas can establish a strong root system and are less likely to be blown over by the wind. 

I netted all of the brassicas against the pigeons.  The mesh is about 1 cm so it will also prevent cabbage white butterflies from laying their eggs on the plants. 

  Some people criticize peat free compost but I find it a cheap and effective alternative to peat based composts.   The use of mychorrhizal fungi makes this compost even more acceptable.   

Everything else, except for the garlic,  is growing very well in the allotment.  I might have the garlic out and put the camomile in its space. 

All the pumpkins have germinated and are growing well.  I may put some gardener’s delight in the allotment greenhous.�
