How to plant spinach

Spinach is an essential addition to any garden plan. However, what steps should you follow to grow spinach effectively? Here’s a comprehensive guide on planting spinach in Kenya.

Step 1: Get the nursery ready

Begin by clearing out all weeds and grass from the nursery plot. Loosen the soil thoroughly to break up clumps and make sure water can drain properly. A week prior to planting, spread a 7 cm thick layer of compost or aged manure over the area.

Make sure to select the appropriate type. Popular spinach varieties cultivated in Kenya consist of Ford Hook Giant, New Zealand, Bloomsdale Long Standing, Giant Noble, and Early Hybrid No. 7. For better sprouting, immerse the spinach seeds in chilly water for one day prior to sowing.

Step 2: Sow seeds in the nursery

Sow your seeds approximately 2 centimeters deep in rows spaced 15 centimeters apart. Top them off with a light covering of soil and apply a layer of dried grass for mulching to help keep the soil moist. Make sure to water the area delicately yet extensively.

Step 3: Nurture the seedlings in the nursery

Once the seeds sprout, eliminate the weaker seedlings and offer partial shading to shield them from intense sun exposure. Make sure the soil remains adequately damp without becoming saturated with water.

Step 4: Transplant seedlings

When your seedlings reach approximately 4-5 weeks of age and have grown their true leaves, you can transplant them. Space each plant around 30 cm apart both horizontally and vertically in the prepared fields. Make sure the area has been thoroughly tilled and smoothed out for optimal growth conditions. Incorporate organic matter like farmyard manure into the soil to boost its nutrient content.

Step 5: Field management

Water your spinach plants regularly since this profitable crop requires consistent moisture, especially in dry conditions. Regularly remove weeds to prevent competition for nutrients and water. You can use mulch around plants to retain moisture and suppress weeds.

Step 6: Fertilisation

At planting, incorporate compost or a nitrogen-rich fertiliser like DAP (Di-Ammonium Phosphate). After 2-3 weeks, apply CAN (calcium ammonium nitrate) or urea to promote leafy growth.

Step 7: Harvesting

Spinach is ready to harvest within two months after sowing, depending on the variety. Harvest leaves continuously to encourage regrowth. Cut just above the soil line to allow the plant to produce more leaves.

How long does it take to grow spinach?

Depending on the variety and growing conditions, spinach typically takes 35 to 50 days to grow from seed to harvest. Here is a breakdown of the key stages of spinach growth time frame:

Germination Typically requires approximately 5 to 10 days under optimal conditions (with soil temperatures between 50–75°F or 10–24°C).
Seedling stage Young spinach plants grow their initial genuine leaves between 1 to 2 weeks post-germination.
Growth and maturity Spinach plants typically become suitable for harvesting young leaves after 20 to 30 days. If you're aiming for fully grown leaves, however, plan to wait around 30 to 45 days instead.

What type of fertilizer do you apply to spinach?

For robust spinach cultivation, apply fertilizers high in nitrogen since this leafy vegetable flourishes with an abundance of nitrogen for dense, verdant foliage. Consider these suggestions:

Organic fertilisers: Organic fertilisers: You can utilize high-nitrogen organic fertilizer such as blood meal, fish emulsion, compost, manure, and alfalfa meal.
Balanced synthetic fertilisers A formula such as 10-10-10 (nitrogen-phosphorus-potassium) offers a well-rounded blend of essential nutrients required for foliage growth, root expansion, and general plant wellness.
Nitrogen-based fertilisers : For a nitrogen boost, a 21-0-0 nitrogen-based fertiliser can be applied, especially after the plants have a few true leaves.

At what depth should you sow spinach seeds?

Spinach seeds ought to be sown approximately 1/2 inch (1.25 cm) into the ground. This planting depth ensures proper germination with minimal effort for the seedlings, preventing weak growth or failed sprouting.

Make sure the soil is well-aerated, nutrient-rich, and abundant with organic material. Plant the seeds approximately 2-4 inches (5-10 cm) apart within rows that are spaced 12-18 inches (30-45 cm) apart to provide ample space for the plants' development.

Elements affecting spinach cultivation in Kenya

Several factors influence the growth of spinach, impacting yield and quality. Below is an overview of some of these factors:

Weeding Regular weed removal is crucial to avoid competition for nutrients and water.
Pests and disease control: Keep an eye out for pests and diseases such as downy mildew, particularly when there is too much moisture present.
