How long does it take spinach to grow?
Spinach requires 6 weeks of cool weather from seeding to harvest, so sow seeds directly into the soil as soon as the ground warms to 40°F. (Cover the soil with black plastic to speed its warming.) Although seeds can be started indoors, it is not recommended, as seedlings are difficult to transplant.
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.
When is the best time to plant spinach? In late winter or early spring for a fast crop and again in late summer or early fall, after the hottest temperatures have passed.
How long does it take to grow spinach? Spinach takes about six weeks to grow from being sown to harvesting. There are both winter cultivars and summer cultivars of spinach, which are sown and harvested at different times. Choose a variety of each to sow and you can enjoy the leaves all through the year.
Most varieties mature in 37 to 45 days and can be harvested as soon as it is a rosette with five or six leaves. Baby spinach leaves have a sweeter flavor and a more tender texture. Spinach leaves should be removed before they get yellow and within a week of full leaf formation.
Spinach likes full sun but will tolerate partial shade. Prepare the planting bed by amending the soil with rich compost or aged manure. Mini-till or spade the ground and level it off with a rake. Mature spinach has a long taproot, so loosen the soil to between 12 and 18 inches.
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. Adding a layer of mulch around the plants also can help to maintain soil moisture.
Spinach grows best when given plenty of fertilizer. Adequate nitrogen is needed to develop the dark green leaf color. Before planting the seeds, apply a general garden fertilizer such as 10-10-10 at the rate of 2 to 3 pounds per 100 square feet. Or, fertilize as directed by a soil test report.
Spinach is high in nutrients and is fast and easy to grow as a cut-and-come again 'baby-leaf' vegetable or for larger leaves. It can be grown all year round if you choose the right varieties and works well in containers too.
The optimal temperature for germination is 70°F; spinach seeds will germinate more slowly at temperatures as low as 35°F. Spinach will not germinate in soil temperatures greater than 85°F.
Will spinach regrow after cutting?
Spinach leaves will regrow in just a matter of days. This is a great method of harvesting spinach if you want the plant to keep growing and produce new leaves, or if you just need a few leaves for a smoothie or a small dish.
1. Radishes. Radishes are one of the fastest vegetables, taking just three to four weeks to reach harvest time.
Spinach does best when growing in moist, nitrogen-rich soil. Spinach plants form a deep taproot; for best growth, loosen the soil at least 1 foot deep before planting. Sow spinach seed as early as six weeks before the last frost or as soon as you can work the soil.
The most common reasons why spinach seedlings die is improper watering (either too much or not enough), too much sun and heat, transplanting, or fertilizer burn. They do best in cold weather and will start to die as soon as it gets hot, so plant them as early as possible.
Within four weeks, the leaves should regrow for a second harvest. If the plant doesn't go to seed, it may produce two or more flushes of regrowth, which allows you to continue harvesting over a longer period.
Long days – 13 hours of sunshine or more – will cause most spinach varieties to go to seed. When summer heat arrives, the leaves also start turning bitter.
Spinach Seeds Not Germinating
If your seeds never germinated, then it was either too wet, too warm, or the seeds were old, and no longer viable. Always plant fresh spinach seeds in well draining, cool soil for best results.

To germinate seeds faster and more reliably, there is a process called “priming.” A week before sowing spinach seeds indoors or out, soak seeds in room temperature water overnight or up to 24 hours.
1. Radishes. Radishes are one of the fastest vegetables, taking just three to four weeks to reach harvest time.
Why is spinach hard growing?
Spinach growing problems are often related to growing spinach in the wrong season. Spinach growing problems are often related to growing spinach in the wrong season. Grow spinach in cool weather. Sow spinach in the garden as early as the ground can be worked in spring.
