A more subtle version of the classic herb for Asian and Mexican dishes.
Sun The amount of sunlight this product needs daily in order to perform well in the garden. Full sun means 6 hours of direct sun per day; partial sun means 2-4 hours of direct sun per day; shade means little or no direct sun.
Days To Maturity The average number of days from when the plant is actively growing in the garden to the expected time of harvest.
Life Cycle This refers to whether a plant is an annual, biennial or perennial. Annuals complete their life cycles in one year; biennials produce foliage the first year and bloom and go to seed the second year; perennials can live for more than two years.
Height The typical height of this product at maturity.
Spread The width of the plant at maturity.
Sow Method This refers to whether the seed should be sown early indoors and the seedlings transplanted outside later, or if the seed should be sown directly in the garden at the recommended planting time.
Direct Sow/Indoor Sow
Cilantro may be grown from seed sown early indoors and transplanted outside after frost or in a container, or sown directly in the garden after danger of frost, or planted as a potted plant. The seeds are called coriander and the leafy green part in the cilantro.
Sowing Seed Indoors:
- Sow cilantro seeds indoors 6-8 weeks before the average last frost date in spring using a seed starting kit.
- Sow seeds ¼ inch deep in seed starting formula
- Keep the soil moist at 70 degrees F
- Seedlings will emerge in 14-21 days
- As soon as the seedlings emerge, provide plenty of light on a sunny windowsill, or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
- Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
- If you are growing in small cells, you may need to transplant the seedlings to 3 or 4 inch pots when seedlings have at least 2 pairs of true leaves before transplanting to the garden so they have enough room to develop strong roots
- Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.
Sowing Directly in the Garden:
- Direct sow in average soil in full sun after all danger of frost.
- Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
- Sow seeds evenly and cover with ¼ inches of fine soil.
- Firm the soil lightly and keep evenly moist.
- Seedlings will emerge in 14-21 days.
- Thin to 12 inches apart when seedlings have three pairs of leaves.
Planting in the Garden:
- Select a location in full sun where water drains quickly after a rainfall.
- Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
- Dig a hole for each plant large enough to amply accommodate the root ball.
- Carefully remove the plant from its pot and gently loosen the root ball, if tight, with your hands to encourage good root development.
- Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
- Use the plant tag as a location marker.
- Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
- Do not allow plants to dry out, but never let the soil stay wet.
- Sow every 3 weeks during the growing season to ensure steady supply.
- Do not fertilize.
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches also help retain soil moisture and maintain even soil temperatures. For herbs, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant's stems to prevent possible rot.
- Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Harvest cilantro leaves before the flower stem has developed.
- Harvest coriander seeds once they start turning from green to gray-brown.
- The leaves may be dried or frozen. Use them fresh in Asian and Mexican dishes; they taste is better than the smell.
- The ripe seeds are an important ingredient in curry. They are also used as a pickling spice or sugar-coated and eaten as candy.
