Tips for Growing Kale
1. Plant During the Best Time of the Year
There are two great times of the year to plant Kale, depending on where you live and how you garden: early spring, slightly before the last frost and on up to early summer, and again in the autumn.
Planting during one of these two times of the year goes a long way in ensuring an optimal yield.
Small plants can be planted in the garden as early as February or March and started indoors even earlier. Seeds need a bit more time outdoors to sprout and start initial growth.
2. Thin Out Seedlings After 2 Weeks of Growth
If you’re planting from seeds, once the majority of them have sprouted into plants, wait a week or two and separate out the extras. This step is known as thinning out.
While thinning out your Kale seedlings, use the extras to plug gaps in your rows, extend your rows, or plant in additional rows.
3. Keep Rows Around 2 to 3 Feet Apart
As you go, keep in mind that Kale plants get pretty big and leafy after a few weeks. That means you need to leave enough space for them to grow and thrive without bumping into each other.
Typically, two to three feet is ample room. Some species of kale require even less space, say, just 12 to 18 inches.
