Fall and winter crops should be planted out during April in the cool, temperate regions of the Southern Hemisphere—Australia, New Zealand, South Africa, Argentina, Uruguay and Chile. And now is the time to enjoy the fall colors as deciduous trees put on their show of the year.
In the coolest regions, plant early in the month carrots, kale, lettuce, radish, broccoli rabe, spinach, turnips, and onion sets. Plant beets, head lettuce, mustard and radishes in the cold frame for winter use.
If you want to build the soil this winter, plant cover crops such as vetch, Austrian winter peas, and burr clover now.
In moderate temperate areas, plant beets, broccoli, Brussels sprouts, cabbage, carrots, cress endive, kale, leek, lettuce, mustard, onions, parsnips, peas, potatoes, spinach, and turnips during April.
In the tropical and sub-tropical regions, now is the time to plant out cool-season vegetables.
