Just like the other greens, Kale is good for succession planting and interplanting. Kale is more heat tolerant than bok choy.
Outdoor Sowing Tips: 1) In order to germinate, kale seeds prefer soil temperature between 55°F and 75°F. Just like lettuce, I usually go for 60°F. 2) Kale seeds should be planted 1/4″ to 1/2″ deep. 3) The distance for full grown kale is typically at least 12 inches apart. Since I am the only one that eats kale in my family, I put four plants per square foot. For baby greens, plant the seeds close together.
Indoor Sowing Tips:  1) Sow the seeds in seed trays under grow lights. 2) I usually transplant in the grow room once the kale seedling has two sets of true leaves and transplant them outside once there are between 4 and 6 leaves. I usually start my kale seeds indoors around 6 to 8 weeks before I transplant them in mid spring. Don’t forget to harden off the plants before transplanting. 3) Use the spacing noted above.
Growing Tips: 4) Keep kale seedlings and plants moist but not soggy! 5) Depending on your soil, you may need to give your kale a little boost of nitrogen. 6) Since slugs may eat your kale, use Sluggo Plus to get rid of them.  Since kale is a member of the Brassica Family, I put netting over my hoops to keep out the cabbage moth and other pests. 7) In the heat, provide some shade. As for shade, you can plant baby kale under taller plants or use a shade cloth over a hoop tunnel.  8) No matter what I am planting in the spring and fall, I am always ready for crazy temperature swings which means I have my garden fabric and hoop tunnels ready to go. 9) Kale is a cold tolerant veggie that enjoys the spring and fall weather.
