A tuning note on this: If you choose to run straight manifold vacuum to your vacuum advance in order to gain the additional timing advance at idle, you must select a vacuum advance control unit that pulls in all of the advance at a vacuum level 2â below (numerically less than) the manifold vacuum present at idle.
To avoid these diseases plant only healthy cloves, manage weeds in the garden, and take care not to injure garlic bulbs while working in the garden. Plant garlic in an area where no onions, chives, leeks, shallots or garlic have been planted for the past 4 years.
To side dress, work the fertilizer in an inch down or so and about 3-4 inches from the plant. Fertilize every three to four weeks. Fertilize your garlic again just before the bulbs swell, around mid-May. By all accounts, however, do not fertilize with high nitrogen foods after May, as this may stunt the bulb size.
