WASABI DARUMA

WASABI DARUMA

Product Description:

A pungent delight seldom available to the home gardener. Even at sushi establishments and specialty grocers, 'wasabi' pastes most often derive their spicy kick from its relatives, horseradish and mustard, and lack the nuanced flavor of true wasabi: an intense, aromatic heat that quickly subsides, giving way to a smooth, sweet finish that lingers. Though chefs use any and all parts of the plant, it is prized for its root, or rhizome, which is grated and served as a ubiquitous condiment for sushi and noodle dishes in its native Japan. Wasabi has now found its way into a broader range of culinary applications, lending zing to traditional sauces, dressings, rubs, cocktails, even ice cream! Roots command up to $100 per pound here in the states, but a few specialty growers and new research from the Pacific Northwest Extension have shown promise for stateside gardens. Our hardy, disease-resistant ‘Daruma’ selection is propagated from disease-free tissue cultures. Attractive plants have heart-shaped to round foliage and will provide harvests of delicious, high quality, thick green roots and multiple plant divisions after 2 years.

Wasabi bare root plants are ready to ship now and are available only within the contiguous US. Naturally resilient to transplant stress, we ship wasabi plant starts bare root with the stems and leaves trimmed away so the plants arrive healthy. We have found that the plants travel better when shipped bare root rather than in pots because the leaf stems of wasabi can be broken during shipping or pull the plant over on its side uprooting it. They arrive ready to plant!

The best wasabi plants I've ever gotten

I was really impressed by the size and health of the plants that arrived. And a tiny rootling of the same was tangled in the roots of a bigger plant, so I got 1/20th of a plant bonus, haha! Couldn't be happier about this purchase!

Not as difficult as these other reviews say

These plants are very resilient. I’ve found them easy to grow as long as you don’t complicate it. Mine are in living soil, fed only water and young coconut powder. Once you up pot these (3gal), after about a year, they really come into it. Water once every couple days and they thrive. I’ve neglected them for up to two weeks and they come back in a few days after watering. Now going 3 1/2 years strong. You can grow this plant, just keep it simple and be like nature

Wasabi growing in aquaculture setup

Not for the faint hearted.
Care level advanced.
Bought three from territorial seed
They are in the picture in the cups.
And two are doing quite well,
The third is slower to recover.
Very slow growing, trim away wrotting leaves and stems to encourage new growth to adapt to its environment.
This is a nursery as I will be growing for seed and this setup is temporary. Very wet semi aquatic.
Waterfall uses small
Pump
Mister fogger is ultrasonic
I do add nutrients to the water
The plants are sitting in sand, mushroom compost, and vermiculite layered and I water them from the top once in a while.
They are in a cool 70 house where the temps are 90 outside.
They have a high output desk florecent that does not shut off.
I am very happy with my purchase and my purchase more.

Wasabia japonica 'Daruma'

Initial Instructions
As home cultivation of wasabi is a relatively recent practice, we recommend growing in containers until you can determine hardiness, shade, and watering requirements and how your own garden and climate suit these. Planting medium should be well-drained with ample organic matter. Work in 10-12 inches of compost to a soil depth of 8-10 inches. A neutral or slightly acidic soil pH of 6-7 is ideal. You may provide a base layer of gravel or sand for drainage. Container size should be 10 inches or larger (at least a 2.5 gallon nursery pot) with enough depth to allow for rhizome development. Rhizomes will typically reach 4-8 inches in two years before harvest but can grow larger. Dig a hole about twice the size of the rhizome you're transplanting, leaving 1/2 inch of the crown exposed above the soil level. Do not bury the crown! Spread out its roots slightly before backfilling the hole and gently pressing into place. Water in well, ensuring that the plant does not sit in its drainage water, which can lead to root rot. Water regularly before the soil dries completely, especially while your roots are just getting established.

Cultivation
Wasabi grows best in full shade with steady temperatures between 50-60°F, though our Daruma strain is more tolerant of heat and light. Temperatures below 43°F slow growth, while 27° F and below can kill the top growth or even the entire plant. Heat damage can occur when air temperatures rise above 82°F, as well as increased pest and disease incidence. If you're outside of frost risk, an ideal spot to set out would be a northern exposure and/or well-shaded spot, perhaps utilizing 75% shade cloth. Irrigate regularly with cool water (45-59°F), misting as needed to keep plants cool and moisten wilted leaves. Mulch can increase moisture retention. Leaves that remain wilted for a week should be removed to deter pests and lower risks of disease. In areas with hard frost, wasabi may thrive indoors; in our zone 7 gardens, container-grown wasabi has overwintered in an unheated greenhouse, as well as acclimating itself to full sun conditions. Stability in growing conditions throughout the seasons provides uniform, high-quality yields. Still, the plants are surprisingly tolerant of variable conditions once established, and will let you know when they're too far out of their comfort zone. Keep the growing medium weed-free and fertilize minimally with a balanced, all-purpose fertilizer until you figure out what works for you; it is better to under-fertilize than over-fertilize. Fertilizers or foliar sprays high in sulfur are said to improve the flavor of the rhizome.

Size/Spacing
8-18 inches tall, 12 inches apart.

Pests & Diseases
Subject to pests and diseases of the brassica family; aphids, cabbage and alfalfa looper larva, crane fly larva, and slugs can all damage crops. Biological controls such as beneficial insects, spraying aphids off with a hose, hand removal of slugs, and pruning of wilted or diseased foliage can decrease these pressures. Careful use of insecticidal soaps or appropriate insecticides may be necessary. Your best defense is maintaining the stable, cool temperatures and steady irrigation wasabi prefers; variable conditions can drastically increase the incidence of pests and disease. While some growers report success replanting year-after-year from divisions, it is recommended to limit vegetative propagation to 3 consecutive years to minimize the risk of disease. You could then use fresh planting stock or learn more about attempting propagation from seed.

Soil Type
Well-drained, very rich in organic matter.

Light Requirements
Full to partial shade, full shade preferred.

Hardiness
Hardy to at least 27°F. If your winter lows are below 30°F, greenhouse or container growing is encouraged.

Harvest
You may harvest a 4 inch or larger rhizome and multiple divisions for replanting 18-24 months after planting. Harvest select petioles (leaf stems) and leaves in the meanwhile for a mild wasabi heat used fresh in salads, sautéed, pickled, or as garnishes; overharvest of leaves can lead to slow rhizome development, so use sparingly. Hand dig your rhizome in the fall or spring, when temperatures are cool and moisture is high. You can pull off the plantlets that will have formed around the crown, replanting those into 6 inch pots, then up-potting into full-sized containers (as mentioned above) the following year to expand your wasabi planting.
