People also ask, what is the best fertilizer for leeks?
Fertilizing Leeks Work compost into the ground before planting. Some blood or bone meal will also encourage them to thrive. If you want to use fertilizer, choose a slow-release balanced granular fertilizer. You can also use a liquid fish emulsion, or just add more compost occasionally.
Besides, what nutrients do leeks need to grow?
Nitrogen Needs All-purpose fertilizer is ideal to get the growing season started. Leeks, however, are heavy nitrogen feeders. Plant them interspersed with nitrogen-producing peas to boost nitrogen levels naturally.
Dig a trench 1 foot deep and 1 foot wide. Fill the bottom with a 5-inch layer of compost and transplant seedlings into holes 6 inches apart. As leeks grow, gradually fill in the trench with more soil, keeping the tips of the plants exposed.
