Globe Artichokes may now be shortened back, the soil forked up, and a mulching of manure given. Jerusalem Artichokes may be cut back also after the tops have matured, but the tubers may be left in the ground until they are wanted for use.
If a constant supply is wanted, and there is a good quantity of roots, some may be put into heat every two or three weeks throughout the winter.
As ground is cleared of crops, it may be taken in hand and dug deeply, or, better still, bastard-trenched if that operation was not performed the previous year. By taking off the top soil a foot in depth, digging over the subsoil another foot in depth, and laying on a coat of manure before replacing the top soil, the ground is greatly improved. The top should be left lumpy, as the weather will crumble it gradually.
This crop becomes a mass of tangled, spreading growth if left alone, and it is best to take it up yearly, storing the best pieces for use, and replanting the thin thongs in fresh ground for the next season's crop.
If a winter crop is wanted, manure may be collected, but it ought to be stored in a dry shed at this time of year until enough has been collected to form a heap, when it may be shaken up to hasten fermentation, turned two or three times, and finally pressed down in a bed. The spawn can be put in when the heat has declined to 850. Afterwards the bed must be covered with an inch of moist soil and a foot thick coating of straw.
Roots can be protected against the effects of hard weather by drawing a little soil over them.
