Easy to grow and delicious to eat, this Chinese broccoli is harvested when the flower stalks are 1-2cm thick, just before the flowers open. Each Green Pearl gai lan seeds plant can be harvested several times, and all gai lan varieties are relatively cold hardy for fall harvests or winter harvests if some protection is provided. Gai lan also makes extremely nutritious sprouts and microgreens. Its thick stems stay crunchy and succulent when steamed or stif-fried. Try heating some oil in a wok, and quickly frying one clove of minced garlic. Toss in some washed, chopped gai lan, and quickly add one tablespoon each of oyster sauce and chicken (or vegetable) stock, and a pinch of sugar. It's ready in just a couple of minutes.
Matures in 50-60 days. (Hybrid seeds)

Starting
Starting
Direct sow gai lan seeds in a shallow trench and bury so they are 5mm (1/4") deep. Water with a mist sprayer or through a fine rose watering can. Thin seedlings to stand about 15-30cm (6-12") apart. Gai lan can also be grown densely in containers and treated as a cut-and-come-again crop of baby leaves.
Days to Maturity
Days to Maturity: From direct sowing.
Growing

Ideal pH: 6.0-6.8. Gai lan is a moderate to heavy feeder that does best in humus-rich soil amended with composted manure. Mix ¼-½ cup complete organic fertilizer into the row before planting. Gai lan does best in cool weather.
Harvest
Harvest
Harvest stalks with the leaves and flower buds intact by cutting each stalk near its base. This may result in numerous tender side shoots. Always harvest before the flowers open.
Seed Info
In optimum conditions at least 80% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 170 seeds, per acre: 30M seeds.
Diseases & Pests
Diseases & Pests
Slugs and snails – Slugs are attracted to beer, so place a little beer in a cup dug into the ground. Sprinkle broken eggshells around plants to deter slugs and snails.
Flea beetles – Use row covers to help protect plants from early damage. Put in place at planting and remove before temperatures get too hot in midsummer. Control weeds.
Cabbage root maggot – White maggots (larvae) attack all plants of the cabbage family. Larvae tunnel in and feed on roots of plants. Damage causes wilting early on, death of plants a little later on.
Cabbage aphids – A hard stream of water can be used to remove aphids from plants. Wash off with water occasionally as needed early in the day. Check for evidence of natural enemies such as grey-brown or bloated parasitized aphids and the presence of alligator-like larvae of lady beetles and lacewings.
Cabbageworms – Handpick and destroy. Row covers may be useful on small plantings to help protect plants from early damage. Put in place at planting and remove before temperatures get too hot in midsummer.
To help reduce disease, do not plant gai lan or other Brassicas in the same location more than once every three or four years.
Companion Planting
Companion Planting
All Brassicas benefit from chamomile, dill, mint, rosemary, and sage. Avoid planting near eggplants, peppers, potatoes, or tomatoes since the level of soil acidity those plants enjoy can cause problems for all Brassicas.

West Coast Seeds is a family-owned company that embraces an organic lifestyle. A group of imagination catalysts and passionate educators, dedicated to producing products and services that better the environment. As part of our mission to repair the earth, we aim to inspire and empower people to take responsibility for the state of the planet. For us, organic is about much more than saying no to chemicals, it is about saying yes to building a healthy soil for the future.
For over 35 years, we have upheld our strong reputation as a leading seed supplier, seeking out the highest quality untreated seeds for organic growing and putting them through rigorous independent testing. We built our company on the exchange of generational wisdom in a masterclass community of newbies and masters alike. Our world may have changed, but our commitment to our people, our customers, and our planet has not.
We’re a values-based business that has blossomed into a lifestyle ethos, with products that support seeders, feeders, keepers, and the tiniest of creepers. Our mission? To mobilize the next generation of gardeners with products that nourish soil and grow vigorous, sustainable gardens. We believe all plants should be grown without the use of chemicals, and that the seeds we supply are an important component of regenerative gardening.
We don’t just offer seeds, we offer experience, insight, and understanding. From timeless garden wisdom to new tech know-how, this is learning on the job: knowledge gleaned not from the pages of a book but from burying our fingers in the soil. We test, experiment, observe and adapt, never happier than when we get to share what we’ve learned with others.
Gardens don’t just grow seeds. They grow minds and imaginations, people and communities. Our vision encompasses both the micro and the macro. We eat locally, protect pollinators, teach people to grow from seed, and support regional biodiversity. We think big but act small and deliver unexpected impact — always with community and purpose.
At West Coast Seeds we believe in the power of small and that little can be large. Like the tiniest seed germinates to evoke incremental change with massive potential, so to can our community of gardeners and growers together. Gardeners are the earth’s stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
