Water and wait!
Check your seeds each day to watch for germination and water regularly to keep soil moist.

Why didn't my kale seeds germinate?

Too much or too little water is the most likely reason for seeds not germinating. With too little or no water, seeds remain dormant. With too much water, seeds become susceptible to rot or infection from soil-borne fungi (also referred to as "dampening off").

Is kale hard to germinate?

Start plants indoors in a seed-starting mix about six weeks before your last expected frost date. Kale seeds germinate quickly in warm soil and should sprout up within five to eight days. Cover the seeds with about 1/2 inch of soil, and keep the growing medium moist.

How cold is too cold for kale?

Frost Hardy Among the hardiest vegetables are cole crops, which can tolerate moderate (24-28°F) freezes: Broccoli; Cauliflower (26°F) Chinese cabbage; Cabbage; Kale; Kohlrabi; Turnip.

How cold is too cold for germinating seeds?

For many garden plants in fact, a soil temperature below 50°F can be a problem. With temperatures in the 40s, seeds will readily absorb water, but not start to grow. This creates an opportunity for disease and rot, which can result in damping-off or poor growth.

How late can I plant kale?

Set out plants in spring 3 to 5 weeks before the last frost; in late summer, you can begin planting kale 6 to 8 weeks before the first frost for fall and winter harvests, and continue planting throughout the fall in zones 8, 9, and 10.

Do you soak kale seeds before planting?

If you're starting the kale seeds off inside, you can simply sprinkle the seeds onto potting compost, lightly cover with compost and water. If you prefer, you can soak the seeds in tepid water for 24 hours before sowing. This should speed up germination.

Starting Kale Seeds Direct seeds will mature in 55 to 75 days, while transplants will speed up the process, ready for harvest in about 30 to 40 days. Plant your crop again in the fall, six to eight weeks before the first expected frost — you can keep harvesting even after snowfall.

Do seeds germinate better in the dark?

Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007).

What helps seeds germinate faster?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Can it be too hot for seeds to germinate?

Most seeds will germinate over quite a wide range of soil temperatures but the speed of germination will vary. Too cold and they'll be very slow to sprout and too hot will also reduce the speed of germination. Far too cold or hot and they'll just fail.
