Garden transplants are usually ready for their first harvest after three months or within 50 to 55 days of planting because they have a head start from seeds. Meanwhile, full-sized Plants grown directly from seeds require 70 to 80 days after planting to reach a mature size.

Also, the time and season of the year and climatic conditions affect the harvest time. Kale grows best in cold weather from early spring to early winter when temperatures are below 80 degrees Fahrenheit. It can tolerate freezing, so it favors temperatures that go below.

Still, the plant grows more slowly when it is below 32 degrees to 20 degrees Fahrenheit (-6° C) hence why it is called winter kale, and the frost sweetens the flavor of kale plants, but a few series of extreme colds might blacken the leaves and eventually kill the plant.

During the whole part of summer, many gardeners have noticed a decline in the taste of larger kale leaves from the sweet taste to a bitter flavor. To prevent this, it’s best to harvest leaves as younglings during the hot seasons.
