Mustard Greens

Amazing horseradish like flavor! A rather delicate, but nicely spicy Micro-Green. To us, the spiciest Brassica of all, our Mustard is called Oriental Mustard.

Note: This is the same seed we sell for Mustard Sprouts. Our Mustard comes from a source which is certified organic.

Growing Basics

Soak

no

The amount of time your seeds should soak in cool water. Soaking is how we begin the sprouting process in most cases.
Rinse / Drain

no

How often your seeds should be watered. Rinsing thoroughly and then draining as much water as possible are key components to growing great sprouts.
Plant

Day 1

Approximate time you will plant your crop if growing Grass, Greens, or Micro-Greens, after soaking your seeds. If your seeds do not soak they will get planted right off the bat.
Harvest

7-8 days

The time it takes to grow a finished Sprout, or other crop (Micro-Greens, Grass, Greens) from a dry Seed. Note: This "finished" Sprout is our preference. you may grow them for as long as you want! In fact, we suggest that you taste them at every rinse to discover when you like them best.

Print Instructions

Plant 1-2 teaspoons of seed (for a 5x5 inch Tray) on thoroughly moistened medium.

Cover your crop with another tray, or a plate - to keep light out and moisture in.

Keep your medium moist by watering lightly as needed. Don't drench!
Use Coconut Coir and you likely won't have to water at all after planting!

When your plants have begun to show leaves, remove cover and move your crop to a well lit location.

Harvest when the leaves are open and an inch or three tall (day 5-14).

Cut just above the medium, with a scissors or sharp knife.

Print Instructions

Yields approximately three times as many Micro-Greens (by weight) as seed "planted"
We put quotes around Planted because the seeds are spread atop a medium - not planted under.

PLEASE read the contents of Notes Tab (to the right)
for variations and a whole lot more information.

Grow these on the ultimate medium -
Coconut Coir, soil, or a soilless medium like Hemp Felt, in a Compostable Tray - or for bigger crops you can use a Growing Tray, like our Half-Crop Tray Set - or go round with our Stainless Steel Sprouter, or its smaller sibling, our small Stainless Steel Sprouter, or - grow them upon a flat Hemp Bag, or in our gorgeous Euro-Sprouter.

I know - too many choices. That's our biggest problem here at Sproutpeople. Choices!
So I'm going to tell you the way I (who have every possible option available) grow Micros.
I always use Coconut Coir!
I mix Earthworm Castings into my Coconut Coir for added nitrogen (which is very good for green plant growth), at a rate of 25% Castings to 75% Coconut Coir.
I grow in our Stainless Steel Sprouter, or its smaller sibling, our small Stainless Steel Sprouter - though I do still like to grow in Trays, like we did when we were professional growers. When I do, I use our Half-Crop Tray Set - because it fits in our (small) kitchen. It's 10x10 inches. Whether I'm growing Cotyledons (my general preference) or going for True Leaves - all these Trays are 2 inches deep. That's the way I grow. I like a deep medium.

Planting

Thoroughly moisten the Medium upon which you are going to grow.

Measure your seed
For a thick crop of Cotyledon (first leaf) Micro-Greens plant the larger amount. For bigger, True Leaf Micros plant the smaller amount.
Stainless Steel Sprouter = 1 - 2 Tbs.
small Stainless Steel Sprouter = 1/2 - 1 Tbs.
Compostable Tray = 1 tsp. - 2 tsp.
5x5 Tray = 1 tsp. - 2 tsp.
10x10 Tray = 1 - 2 Tbs.
10x20 Tray = 2 - 4 Tbs.
Hemp Bag = 2 - 4 tsp.
Euro-Sprouter = 1 - 2 tsp.
If you are going for True Leaves you really must use a Growing Tray that is at least 2 inches deep, and plant on Coir with Castings.

Spread seeds as evenly as you can - all over your thoroughly moistened Medium.

If your growing on a pad, like our Hemp Felt, mist the seeds with a Spray Bottle to provide them more water to soak up.

Cover your crop: If you're planting in a 5x5 Tray use another identical tray - up side down. Same thing with other Trays. If using a Compostable Tray snap the clear lid on for the first 2-3 days. If using a Hemp Bag, or another medium - be creative. If it's on a plate then use an identical plate (upside down) as a cover. For the Euro-Sprouter - use the cover that comes with it. It is not mandatory when growing Micro-Greens to cover them at all. Experiment for yourself and see what works best in your climate/location. I covered everything for 27 years- but I now have questions thanks to growing in our Stainless Steel Sprouter - about whether covering helps every crop. It doesn't hurt - I KNOW that, but - well - watch this movie if you care about this fine point, otherwise grow on...

Place your Micro-Garden in a low-light, room temperature location (70° is optimal).

If your growing on Hemp Felt, mist the seeds with a a href="/spray-bottle/">Spray Bottle once or twice a day, until the roots bury themselves in the hemp.
If growing on Coconut Coir - your seeds will get all they need from the Coir, but mist once a day if it pleases you to do so.

Growing and Greening

Once germination occurs - keep the medium moist by watering gently or misting with a Spray Bottle every day or three. The deal with watering is that the deeper your medium, the less you need to water, and the plants won't require a lot of water until they get growing big - at which point you may need to drench the medium every day. When using our Compostable Tray (which has no drainage) you can pour off excess water by tipping it.

Note: These wonderful little Brassica plants have a unique root structure. Brassicas will show microscopic roots starting on day 2 or 3. They are called root hairs and are most visible just before watering - when the plants are at their driest. These root hairs impress many people as mold - but they are not. When you water your crop the root hairs collapse back against the tap root. Viola! No root hairs! Now you know. Isn't learning fun?!

When your plants grow up and begin to shed their hulls they are ready for light so move them (if necessary) to a well lighted location. If you go with sunlight - water more frequently. Room light will usually do quite nicely - and will not dry out your medium as quickly. One consideration here - if you are going for True Leaves you should definitely use sunlight in a warm place.
The most beautiful Micro-Greens we have ever seen were grown in a greenhouse in Burlington, Vermont (in summer) by our friends Spencer and Mara at Half-Pint Farm. Just had to mention that. They taught me and Lori a lot!

Keep the medium moist by watering regularly. Water from the side if possible to prevent injuring the tiny plants.

When your plants have open leaves which are green, they are done - unless you're going for True Leaves, in which case you need to keep watering and tending for another week or more.

Harvest

Cut the plants just above the medium upon which they have grown. During the final 8-12 hours minimize the surface moisture of your plants - they will store best in your refrigerator if they are dry to the touch. So if you water try to keep the water off the plants - just water the medium.

When you are ready to store them (I'll remind you that these degrade fairly quickly, so eat them instead of storing them if you can), if they are still damp - lay them between some paper towels or anything you prefer, and dry them very gently. Transfer your crop to a plastic bag or the sealed container of your choice - glass is good. We sell an amazing Produce Storage Bag that actually extends the shelf life of produce, if you're interested in the best of the best =;-) Whatever you store them in; put them in your refrigerator - if you must.

Great Job Sprout farmer!

Oriental Mustard seed planted on my thoroughly moistened medium: 60% Coconut Coir, 20% Vermiculite, and 20% Earthworm Castings.

12 hours later...
Look at That! There is already germination happening.

This close up shows - in addition to seeds which are sprouting big roots - tiny root hairs which grow off the main (tap) root. They are microscopic roots! They are NOT mold!
They are good. They are amazingly beautiful. If you have a magnifying glass, take a look. When we see Root Hairs on sprouts they disappear after Rinsing because the water makes them fall back along the tap root. Since we are not watering our Micros they stay visible. If you were to water now they would vanish. Enjoy them.

12 hours later...
We can already see leaves opening!

A closer look at the same time.
Aren't you glad you know about root hairs?!

12 hours later...
So many leaves are open that it is time to uncover our crop.
Move your tray to a well lit location. Sun is fine and dandy when growing Micro-Greens.

12 hours later...
Now THAT is progress! Nature just blows my socks off!

12 hours later...
We can see most of our crop already has open Cotyledons.
The little round yellow things we see amongst the leaves are the seed coats (hulls) which have yet to be pushed off by the leaves unfurling from within.

12 hours later...
Nary a hull remains.

20 hours later...
Sorry for the time warp. We had to get to the seed shop, or it would have been 24 hours.
I'm particularly fond of shooting from a low angle, and I love the heavy backlight that makes our crop look otherworldly in this picture.

15 hours later...
FYI - I still haven't watered my crop. In fact I never did. All the moisture and nutrition that was needed was served to the little mustard plants by my thoroughly moistened medium of 60% Coconut Coir, 20% Vermiculite, and 20% Earthworm Castings. Those tall Micros in the background are Radishes which were growing in the crop behind this crop of Mustard Greens, which was our Long Life Mix grown as Microgreens.

12 hours later...
Just Lovely!

12 hours later...
They are only 2 inches tall, but they pack a wallop nutritionally and flavor-wise!
It's time to harvest. Get a pair of scissors and snip your crop close to the medium.

Don't they take a pretty picture?!

Tastes just like horseradish. One of the MOST amazing flavors in the sprout universe!

This is Oriental Mustard - it is a yellow seed and is the only Mustard we have ever seen that is not muciloginous. Oriental Mustard is hard to find as very few farmers grow it. We have gone years without it more than once, so get it while you can. Our current crop is something of a miracle in fact. Early snow in Saskatchewan this past fall buried a beautiful crop of Oriental Mustard. The miracle is that there was a freak warm spell in November (amazing!) that lasted long enough (amazing!) for the seed to get harvested. Beyond that, the moisture did not damage the seed. That is truly amazing.

You can also grow Oriental Mustard as a Sprout.

Note: Canadian and US researchers have found that Brassicas contain antioxidants such as sulfurophane. Mustard is a Brassica.

Another fantastic batch of our favorite Mustard. A very prolific seed!

Seed Shelf Life: 5 years. Store in cool, dark, dry spot. Store in freezer to extend shelf life.

Sproutpeople and Micro-Greens

We first grew Micro-Greens back in 1994. We were way ahead of the curve. Nobody was interested in them - not our farmers market customers, not our food stores (co-ops, natural food stores and grocery stores we delivered to every week), not our restaurants, nobody! That did change some as the years passed, but we were always Sprout People first. Frankly, we prefer Sprouts to Micros because we find them plumper and more texturally pleasing - but we keep working with them. Some seeds (especially mucilaginous seeds) won't grow as sprouts and Micro-Greens are SO gorgeous and offer a lot of unique and really cool possibilities.

Soaking and Pre-Sprouting

Though our instructions (in the Growing Instructions Tab - to the left) used to suggest these steps (for non-mucilaginous seeds), we have found them less and less necessary as we've worked with Micro-Greens. We skip both now, concentrating first on thoroughly moistening our medium. We then plant the seeds (which are just spread atop that thoroughly moistened medium), and mist them with a Spray Bottle, when appropriate. We then cover our planted seeds. We mist them with a Spray Bottle at least once a day until they sprout, and then bury their roots in the medium. During those first 2-3 days we are misting heavily for some - - not at all for others. We uncover the crops at different stages, depending on what we are doing with a particular crop. Keep reading to learn more.

Fertilizing Micro-Greens

When growing on a soilless medium like Hemp Felt - it is advisable to use Liquid Kelp Feritlizer to give your plants additional nutrients to draw upon. When we use Kelp we dilute 1 tsp. in 1 quart of water (this is a higher concentration than the product label calls for). We use it in a Spray Bottle or by watering the medium directly. We use it every time we water. The perfect container for these soilless mediums is our inexpensive Compostable Tray. If you plant on soil - or better yet with Coconut Coir (our FAVorite), mix in 25% Earthworm Castings for the ultimate nutrient rich, moisture retaining planting medium. Mix them together thoroughly before moistening.

Micro-Green Variations

There are varying opinions of what constitutes a Micro-Green. Traditionally it is just a plant grown to the Cotyledon (first leaf) stage, and cut above the medium upon which it is planted. When we grow to this stage; we either grow on Hemp Felt, soil (any kind will do) , or our favorite - Coconut Coir. Hemp Felt is less messy and works fine and dandy. We cut a piece to fit a plate, then we follow our own instructions for keeping the medium and seeds-sprouts thoroughly moist. We use another of the same size plate - inverted - as a cover. We uncover our plants when they are about 1/2 inch tall, or when they are hitting the covering plate. We then expose them to all the light our kitchen has to offer. We even use direct sunlight when available. We have to water them more often when we do this. When it comes to watering, We mist them with a Spray Bottle until the seeds have firmly rooted. After that - when growing on a piece of Hemp Felt on a plate; pour water directly onto the plate. We gently tip and turn the plate so as much water as possible gets soaked up by the Hemp Felt, and then pour off most of the excess. When growing on soil or Coconut Coir; we continue to spray with the Spray Bottle, but we keep the medium moist by adding water directly to the plate or solid tray it is sitting on/in. We allow the medium to drink up what water it can, and then gently pour off the excess. Leaving a little water on the plate is fine - it will get sucked up before your next watering. If it doesn't, cut back a bit next time.

There are some nowadays who want a Micro-Green to be a plant which puts out a True Leaf before they'll call it a Micro-Green. We find that concept Very interesting, so we have worked to make that happen.

True Leaves

The first thing is to plant less seed. Just how much is the question. The general rule is this: The more space your plant has to grow roots - the bigger it can grow. We are currently using 1/4 teaspoon in a 5x5 inch tray. That leaves quite a bit of room between the seeds-plants, but gives them enough space to grow to the True Leaf stage. This can take 2 weeks or more. The main thing that is needed is More Light. Plants get "leggy" when they need to reach for light. We use that to our advantage in all other circumstances in the Sprout World, but here we want to minimize the legginess of the plants. If you can put a light right above your crop - or keep it in direct sunlight, that will help. Keep everything adequately moist. Remember - the more light the faster the medium and plants will dry. This may sound like a lot more work, but really it isn't much more than usual. We cover the seeds only until they have sprouted when growing this way. We plant on Coconut Coir (which hold moisture like nothing else we've ever worked with) enriched with 25% Earthworm Castings, which add nitrogen that a plant uses to grow leaves. When making up the mix, do not exceed 25% Earthworm Castings as too much nitrogen can burn your plants (they actually whither and die when the soil is too "hot" - which means it has too much nitrogen). Mix the castings into the base Coconut Coir, or soil (any kind will work, though we do not advise mixes that are heavily peat moss as we find it hard to work with and we don't find the crop turns out as well) - it is the roots that will need access to the rich medium. If growing a mix, not all of the plants will grow True Leaves at the same time. Keep growing until most have them. Harvest then and eat them up. Though you can store Micro-Greens, they degrade quickly, and since you have put so much work in these - you should enjoy them at their peak.

The Next Variation

The next obvious step (to us anyway) we find really exciting. It is to grow even fewer seeds into even fewer plants. Those plants will grow more leaves. They will be more like Baby-Greens than Micro-Greens. They will require more time. They may re-grow more quickly because they'll have a bigger root-mass. The container (tray, pot, etc.) they grow in will likely be too small for that root-mass to live long, but it's possible. When it comes right down to it, we're talking about an indoor-garden. All the other stuff we offer is about indoor gardening, but this is more like a garden. Not many of us have space in our homes to Garden inside, but we love the idea. We're working on this, and we'll tell you what we find out as soon as we know something. It was gardening that eventually led us to sprouting. We feel like this is closing that circle started so long ago - now it is sprouting leading back to gardening @:-) Start with Coconut Coir enriched with Earthworm Castings and you'll have a great experience. Happy Micro-Greening!
