Spinach can be either sown directly into the garden or started from seeds indoors. For the least work and the most convenience, seedlings can also be purchased from a nursery in spring. To give spinach a head start, plant seeds in sterile seed-starting mix indoors about six weeks before the last expected frost date.
When should I start spinach seeds?
Sow spinach seed as early as six weeks before the last frost or as soon as you can work the soil. Prepare the soil the previous autumn, and you’ll be able to drop the seeds in barely thawed ground come spring. In areas with a long, cool spring, make successive plantings every 10 days until mid-May.
How long does it take spinach seed to germinate?
5 days
Spinach will germinate at soil temperatures between 40-75°F. Spinach takes up to a month to sprout at 40° while it may only take 5 days at 75° but at higher temperatures you may only see 30% germination rates. For best results soak seeds over night in water one week before planting.
How big should spinach seedlings be before transplanting?
Once the seedlings have germinated and are about 3 to 4 inches (7 to 10cm) tall, fertilize them once a week with dilute fish emulsion or another nitrogen fertilizer, and lush, dark green leaves will develop and quickly grow.
Do spinach seeds need sunlight to germinate?
No, spinach seeds do not need light to germinate.
What temperature does spinach germinate?
45⁰ F to 68⁰F.
One key to successfully growing spinach is to plant the seeds when soil temperatures are cool. Spinach seeds germinate best in a soil temperature of 45⁰ F to 68⁰F.
How often do you water spinach in a greenhouse?

How long does it take to grow spinach indoors?
How Long Does Spinach Take to Grow Indoors? Spinach is a fast-growing plant. The time of growth varies depending on the type of spinach, but usually, it takes 6–8 weeks after you plant spinach to harvest.
How deep do you plant spinach seeds?
Spacing & Depth
Sow 12 to 15 seeds per foot of row. Cover 1/2 inch deep. When the plants are one inch tall, thin to 2 to 4 inches apart. Closer spacing (no thinning) is satisfactory when the entire plants are to be harvested.
How often should spinach be watered?
Water spinach frequently to keep the soil evenly moist but not soggy. Regular watering is essential in warm weather to prevent bolting. In general, spinach needs around 1 to 1 1/2 inches of water per week. Rather than a weekly deep watering, it’s better to water several times a week.
Why is my spinach not germinating?
Your Soil Is Too Cold Or Dry
Another reason your spinach seeds are not germinating has to do with soil conditions. If the soil is too cold, then your spinach seeds might not sprout right away (whether you are growing indoors or outdoors). They may sprout when conditions improve and the soil warms up.
Should I direct sow spinach?
Spinach is grown from seeds or transplants. Direct-sow spinach seeds in the garden 6 to 4 weeks before the last spring frost; spinach can be started indoors a couple of weeks earlier. Sow seed ½ inch (13mm) deep. Sow seeds 1 inch (2.5cm) apart; later thin seedlings to 6 inches (15cm) apart; use the thinnings in salads.
What happens if you plant spinach too deep?
Low germination rate – even if some seeds germinate, you may see a lower germination rate, which will result in wasted seeds and empty space in your garden. Slow germination – seeds that are buried too deep make take a long time to sprout, possibly due to lack of water.
Will spinach grow back after cutting?
Once you’ve harvested your spinach, all you need to do is water it and wait patiently for the next harvest. Spinach leaves will regrow in just a matter of days.
Why are my spinach seedlings leggy?
Seedlings tend to grow leggy when they’re straining for light, which supplies a valuable learning lesson for next time. So, continue to get a jump on your spinach crop by planting seeds about four weeks before the last frost date for your area. Be sure to place the seedling tray near a window that gets plenty of sun.
How do you plant baby spinach seeds?
Growing baby spinach outdoors
Sow the seeds directly into the soil ½ an inch (1 cm) deep and about 2 inches (5 cm) apart. Cover the seeds gently with soil and water well. I like to plant a couple of rows every 2 weeks so that the leaves aren’t all ready to harvest at the same time.
Does spinach like sun or shade?
It needs full, direct sunlight to grow quickly, which is the key to producing sweet-tasting spinach. As spring transitions into summer and summer into fall, spinach does better in partial shade. Temperatures above 75 degrees F.
How cold can spinach seedlings tolerate?
20°F.
Spinach is a cool-weather crop that grows best when the daytime temperature remains consistently below 75°F–commonly in spring or fall. Young plants will bolt when exposed to temperatures below 40°F, but mature plants can withstand temperatures as low as 20°F.
Do seeds germinate better in the dark?
Most seeds germinate best when they’re placed in the dark. The presence of light, which is crucial to seedling development, may actually stunt the process of germination.
