Hi all I'm new to the site but not to gardening (allotment type) I must confess that if you ever asked what type of Beans, Potatoes or sprouts I put in last year, I probably would not be able to say. Even though I have gardened for 40 year I enjoyed it but did not take to seriously and for most part supplied the home with plenty of good fruit and veg.
My garden is about an 8th acre, it's not actually an allotment but a piece of old Railway land on the end of a row of Railway cottages and I think the soil is made up of old dry toilet waste because it is nearly Black, full of ash (no soil born slugs) and no clay. A few year ago I started to get more than the usual problems with pests and moulds on my Brassicas, the worst being a Grey aphid as small as dust on my sprouts that is driving me mad.
I have tried to combat with sowing and planting borders of a variety of perennial Herbs, garden now full of Bees in the summer. I have divided the main plot into three 20 x 20 Feet plots with a couple of small plots at opposite ends , I now rotate the Three main plots, with the use of short scaff tubes and roof lattes covered with debris net I keep the Butterflies of my Brassicas But can walk in to plant and maintain. I have Limed this plot and I have a load of Farm manure delivered every year for the others and am now trying to rotate as best I can.
If you are still awake my question is can I replant Brassicas within the Brassica plot in the same season as my family is now three separate families and I require quite a lot to supply them all. Should I re-lime for a new row Cabbages ect: or should I incorporate manure now that its probably being 6 month since I Limed the plot or just apply growmore. Also how do I stop the Grey dust aphids from infesting my Sprouts. All advice appreciated.
