Garlic can be planted in fall or early spring. However, like onions and other spring-blooming bulbs, garlic needs cold weather to develop good bulbs. When grown in hot summer, garlic heads don't divide into cloves and you end up with onion-like bulbs instead. So you plant your garlic in winter for best results. Here are the steps:
Get garlic bulbs from the shop or from the market or from previous harvest.
Break apart cloves from the bulb.
Prepare the bed and broadcast compound C fertilizer or use organic manure such as chicken manure or compost.
Plant garlic cloves 1 to 2 inches deep in warm climates such as Southern Hemisphere or 3 to 4 inches deep if you are in the Northern Hemisphere.
Place the flat, rooting plate down into the soil so the pointy end of the clove sticks up.
Water your garlic three to four times a week.
Once they reach about 6 inches tall, add a layer of compost or animal manure alongside them. If you don't have animal manure, use Ammonium Nitrate fertilizer and feed the garlic.
Continue watering your garlic three to four times a week for three months.
Garlic is ready for harvest when the stems are beginning to dry up. You can uproot just one plant and see if the bulb underground has grown big enough to get harvested. That will tell you whether to harvest the rest or not.
