YOUR SIMPLE GROWING PLAN
One pot. Here’s the plan.
A cool, bright patio or balcony. Start with seeds.
One draining square planter with room for roots.
Two seeds at four spots, 6 inches apart; this is a leaf-harvest plan.
- 01
Sow in the final pot
Dampen the mix. Mark four spots in a 2 × 2 grid, 6 inches apart.
- 02
Cover four pairs of seeds
Place 2 seeds at each spot and cover with ½ inch of mix. Water gently.
- 03
Keep the strongest at each spot
Keep the surface moist during sprouting. Once seedlings are established, snip extras to leave four plants. A round coriander seed unit can produce more than one seedling.
- 04
Snip a few outer stems
Wait until plants have plenty of growth, around 6 inches tall. Take a small amount and keep the center and healthy leaves intact.
Another way to start
Use small nursery starts+
Choose 4 young plants, keep each root ball intact, and set them at their existing soil level in the four positions. A large plant already sending up a flower stalk is a poor shortcut to a long leaf harvest.
When to water.
Check the mix each morning. Keep the surface damp while seeds sprout. For established plants, water when the top inch is starting to dry, then let the pot drain completely. Do not leave it standing in a full saucer.
Exactly what to feed it.
With fresh enriched mix, skip extra feed at sowing. This short cool-weather leaf crop may finish before the starter nutrients run out.
A LIGHT TOP-UP ONLY IF NEEDED LATER
Miracle-Gro Water Soluble All Purpose Plant Food (US 24-8-16)
If the plant is still making usable leaves after the starter feed ends, mix 1½ teaspoons of the US 24-8-16 product into 1 gallon of water. Apply at the roots every 4 weeks outdoors. This is half the outdoor label concentration, following University of Minnesota container-herb guidance. Do not feed to try to reverse bolting.
Check the manufacturer’s product page ↗Use the named US formulation. A different product or concentration needs different directions. The amount mixed is a batch, not a dose to pour into one pot.
A little patience pays off.
Germination can take about 3 weeks, so keep the pot labeled and the surface moist. A slow-bolting variety still eventually flowers; it is not a permanent supply of leaves.
When should I start where I live?+
Choose cool spring or fall conditions. In warm climates, the useful growing season may be winter. Heat and lengthening days can shorten the leaf-harvest period.
For regional planting windows, find your local Cooperative Extension office ↗.
Something looking off?
Are cilantro and coriander different plants?+
They are the same plant. In US cooking, cilantro usually means the leafy herb and coriander means the mature seeds.
Why are new leaves thin and feathery?+
The plant may be moving toward flowering. Harvest useful leaves and plan another sowing; cutting off one flower stalk will not make it young again.
Can I keep harvesting all summer?+
Hot weather often cuts the leaf season short. Try another small sowing when conditions are cool enough instead of promising one plant will last indefinitely.
A little more growing know-how.
Leaves are the goal here+
Four widely marked positions keep this first sowing easy to manage. The recipe is not a dense commercial herb crop or a dedicated coriander-seed production plan.
A fresher next batch+
Write the sowing date on the pot label. Once you know how cilantro behaves in your spot, stagger another pot to reduce the gap between leaf harvests.
