Growing Tips, Tricks and FAQs

Growing Tips

Merlo Nero spinach is an Italian heirloom variety known for its dark green, savoyed leaves. It thrives in cooler weather and is quite hardy, making it suitable for early spring or late fall planting. This spinach variety prefers full sun but can tolerate partial shade, especially in warmer climates to avoid bolting.

When to Grow

Merlo Nero spinach should be planted in late winter/early spring, just as soon as the soil can be worked. It performs best when temperatures range between 45-75 F. It will also do well when planted in late summer/early fall. This variety can tolerate light frost, which makes it a great choice for overwintering in mild climates.

How to Sow and Plant

To sow Merlo Nero spinach, plant the seeds directly in the ground at a depth of about 1/4 inch. Space the seeds about 2 inches apart in rows that are 12-18 inches apart. Thin the seedlings to about 6-8 inches apart once they develop a few true leaves to provide adequate space for growth.

How to Grow

This spinach variety prefers well-draining, fertile soil rich in organic matter. Adding compost or aged manure before planting can significantly boost growth. Mulching around the plants can help retain moisture and prevent weeds. Regular watering is important, especially in dry conditions, to prevent bolting. Avoid overhead watering to reduce the risk of fungal diseases.

How to Save

  • In spring, plants will grow tall and bloom (or bolt) as soon as the days are longer than 14 hours. Heat also speeds up bolting, since spinach prefers temperatures between 35 and 75 degrees.
  • Commercial spinach seed crops are separated by 5-10 miles. Spinach pollen is so fine that it easily penetrates mesh screening, but is severely restricted by spun polyester fabric.
  • Plants are either male or female. Maintain a ratio of one male to two female plants, though this is hard to determine until the seed stalks have formed. Close plantings in wide beds will provide the greatest chance that the ratio will be hit.
  • Starting at the bottom of the plants, strip off the seeds (using gloves for the prickly type) in an upward motion, letting them fall into a bag.
  • Allow to completely dry and store.
  • They will retain 50% germination for up to 5 years when stored in ideal conditions (cool, dry, and dark).
