transplanting spinach seedlings

Spinach is a simple and versatile crop to grow, from direct sowing into the garden or starting seeds indoors.

Scientists recommend priming spinach seeds before planting to increase their chances of germinating more rapidly and reliably. Primed seeds retain more moisture to help facilitate initial stages of germination.

Planting Directions

Spinach is an ideal cool-season vegetable to grow in soil with ample nutrition, good drainage and neutral to alkaline pH levels. To produce vibrant leaves, nitrogen must be available continuously throughout its lifespan; adding balanced fertilizer mix in spring can provide this. For poor soils, work in some compost or worm castings before transplanting any seedlings of spinach seedlings into their beds.

Transplant spinach to a sunny location in your garden and avoid planting near other vegetables that need more nutrients or water than spinach does. When growing spinach in containers, select wide pots or troughs so you can easily space out plants, and make sure the container’s soil contains lots of organic matter for proper drainage.

Maintain a constant moisture level in the potting soil to help protect spinach plants from bolting or disease, or in container growing add a three-inch layer of mulch at the base of each pot to retain moisture and manage weeds.

Plant spinach during the fall after the last frost has passed and before temperatures heat up and become dry and hot. This gives the spinach plant time to adapt and mature before temperatures heat up, thereby decreasing chances of mildew or damping off occurring in its development.

Once your plants have reached a satisfactory size, thin them out so that each row has three-inch spacing between each plant – this will free up space for other crops or increase harvest yield.

After your spinach seeds germinate, harvest individual leaves at random or cut down all of the plant just above soil level to ensure you collect every leaf.

Harvesting baby leaves requires extra caution as they’re tender and easily damaged, making the harvest process delicate and time consuming. They make a tasty addition to salads or soups/stews!

To prevent bolting, water your soil regularly and cover it with mulch to retain moisture and deter weeds and pests while simultaneously increasing soil nutrients. Mulch can also help suppress weeds while deterring pests while also maintaining its nutritional quality.

Soil Preparation

Spinach seedlings require well-draining soil in order to thrive. Before transplanting them, amend your soil by amending it with 2-4 inches of compost tailored to your area’s growing conditions. In addition, lime may also help raise its pH from acidic levels (pH 7.0 or below) into neutral territory (pH 7.0 or greater).

When planting spinach in containers, ensure the pots receive regular doses of water to promote its growth and avoid bolting. Furthermore, mulch around each plant to maintain soil moisture levels and limit weeds.

Before transplanting spinach, be sure to remove any damaged leaves or stems that could harbor disease. White rust, a fungal disease affecting spinach plants, can cause yellowing or stunted leaves and stems. To combat this issue, choose disease-resistant varieties like “Indian Summer” and “Tyee”.

Pests that threaten spinach include leaf miners, aphids and mites, slugs and snails. These insects can reduce plant stands while also leading to leaf rot; use anti-aphid or mite killing agents or spray the leaves with neem oil spray to stop their harm.

Slugs can wreak havoc on plant roots and young leaves, so control them with insecticides or traps. Mature leaves that have already been chewed through can become vulnerable, but planting varieties like Sunnyside or Giant Noble that resist slugs could save your crop from damage.

Aphid-borne white rust is another potential spinach disease, appearing as yellow spots on upper leaf surfaces and white pustules underneath leaves. To combat it effectively in cool weather conditions, infected leaves should be collected by hand and placed into garbage cans as soon as they appear.

Downy mildew, which appears as mold on the underside of leaves, can also be an issue. Since downy mildew thrives during rainy weather conditions, to reduce its spread make sure not to work or walk through wet areas in your garden.

If your garden soil is acidic, add a small amount of lime (based on soil testing results) into the top six inches before transplanting spinach plants to increase its pH to neutral and ensure healthy, robust results.

Spinach plants thrive in moist, fertile soil that is high in nitrogen for maximum leaf development. At transplant time and every two weeks thereafter to maintain strong plants. Fertilize accordingly!


If you’re growing spinach in a pot, direct sowing is usually best. Spinach seedlings are extremely sensitive to root disturbance, and transplanting them could trigger it prematurely. To address this problem, mix a cool-season organic fertilizer such as fish emulsion or compost tea into the container soil prior to sowing your seeds.

Soil pH is also an integral element in growing spinach successfully. For vibrant leaves and lush stems, soil should have an ideal pH range between 6.5-7.5. If your soil has acidic conditions, add finely crushed eggshells into your potting mix prior to planting for acidification protection.

Once your seeds have been planted, make sure they receive ample water to ensure rapid germination and growth. A layer of mulch such as hay or straw may help reduce weeds which could otherwise wreak havoc with spinach roots.

Once seedlings reach two inches tall, thin them out by spacing them four to six inches apart to promote strong and healthy growth and ensure you a larger harvest.

Reseed your spinach every few weeks to prolong its harvest period if you live in a warm climate and plan on harvesting in fall/winter months. This strategy may prove particularly helpful.

Sow seeds indoors approximately six weeks before your estimated last frost date for optimal results. Seeds should germinate approximately one or two weeks post-sowing; to increase soil temperature further use a seed starting mat.

Spinach seeds generally take six weeks to mature in a garden from seed; however, depending on weather conditions it could take up to eight.

If you want to extend the harvest season, plant seeds in the fall and cover them with a cold frame or heavy-duty row cover from frost in order to allow them to continue maturing through most parts of winter. This will allow them to come full fruition during spring.

Harvest the plants when their leaves are full of healthy leaves and before flower stalks start forming. You can enjoy eating individual leaves from these harvests; however, their stems, buds and flowers could turn bitter over time if left alone for too long.


Spinach is an iron-rich cool season vegetable, widely utilized as part of various recipes and salads alike. Additionally, its easy cultivation requires little maintenance.

Transplanting spinach seedlings is the quickest and easiest way to ensure a consistent supply of this leafy green, but its delicate roots should not be disturbed during its transplanting. Instead, place them directly in their garden bed or container where it will live for maximum success.

When growing spinach in containers, use a well-draining potting mix that mimics ground soil in terms of drainage and texture. Furthermore, add small amounts of compost for extra nutrition in addition to fertilizers or additives for plant support.

Sowing spinach seeds early in the spring will give their seedlings ample time to mature in cooler conditions while developing strong roots before summer’s heat sets in. You could also sow your seeds later if it is not grown regularly in your area; though if this occurs you may have to wait longer for flowers and leaves.

As your spinach plants develop, be sure to thin them out so they remain at least 6 inches apart for maximum health and disease-prevention. This will allow them to grow efficiently without the risk of spreading disease among them.

Spinach is an avid feeder, so side-dress with compost tea or liquid nitrogen-rich fertilizers regularly to maintain proper nutrition levels for this crop. Avoid overwatered soil conditions and only provide additional irrigation when it’s necessary.

Pests that threaten spinach include flea beetles, spider mites, aphids and squash bugs. Use appropriate insecticides when planting or after seedlings have emerged to effectively manage these problems.

Downy mildew (which usually appears during cooler weather) and white rust are two diseases that can impact spinach plants, but both can be prevented by changing where you grow your spinach from year to year and selecting resistant varieties.

If your spinach plants become yellow or die, check for fusarium wilt, an infectious fungal disease spread by cucumber beetles and aphids that causes stunted growth. If any wilted leaves or yellow spots appear on the plant, destroy it immediately without trying to regrow.
