Only one of the 10,000 (doubt this is even correct) seeds sprouted. One...The quality is so horrendously inconsistent, and the cost for these seeds is so high. It's really disappointing. The seller also has it set that you have to return the item for a refund (you can disable this as a seller). They are just hoping enough friction is created by Amazon on their behalf so there is no return. You cannot exactly pickup each seed from the ground and return it. Either way, steer clear, this seller 'acts' like they are a small independent business, but clearly, the independence they have is from the money they take from us.Reviews seem to validate this, the consistency is all over. So, this may be due to poorly stored seeds (who knows how they're kept), really cheap seeds, etc...

None of these grew, though it was probaby my fault for not trying very hard, but they should really be mixed with a bit of fill material that you can actually spread. These seeds are so small I couldn't even spread them with a salt shaker or see where they went at all.

This is one of several seed packets I got from this company this year, and I’ve had excellent luck with all of them. I definitely plan to purchase more Irish moss of these ones! (Go to bottom for growing tips.)I had bought one Irish moss plant from a local nursery a couple years back and realized it’s strongly perennial in my growing zone (8b), perfect for a shady east-facing area I have that only gets morning sunlight, and it even happily thrived through periods of snow cover in winter and an entire summer of neglect. Instead of dying, the neglected moss just stopped spreading so I hadn’t realized what an adorable ground cover it can be until this year.Plants are too expensive, so I’ve been starting everything from seed this year. I knew I’d have an easy time with pumpkins and sunflowers, but Irish moss??? The seeds are minuscule specks—you need a steady hand or a very tiny spoon or something to mete them out into peat pots. And definitely don’t sneeze! After they arrived and I really got a look at them, I decided there was zero chance this was going to work, and even if they germinated, there was NO way I could keep them alive long enough to grow and get established before winter.However, the germination rate on these seeds is high, and I actually find the seedlings MUCH easier to care for than, say, your average windowsill herb kit. The compact height makes everything a cinch: there’s no risk of them getting leggy and tipping over, or needing a deeper planter for their root system, so you can stick a peat pot of moss into just about anything—a plastic cup, bonsai planter, yogurt container. I now have several plugs of moss thriving, and several more growing in intermediary pots. I also made a bunch of mistakes and killed some other moss plugs, so I compiled a list of tips.Hope it helps!===========Growing tips:TL;DR: Start indoors in high-humidity setup, preferably with a lid. Once you have seedlings, let them get more air circulation. After planting, you may need to water multiple times a week, possibly daily. Keeping them in pots for a few weeks helps them get more established before putting them in the ground. No hot afternoon sun, ever. Water next to the plant, not directly on it—your garden hose can easily demolish a baby moss. Huge temperature fluctuations (40-50 degrees F) seem fine, but could stunt the already slow growth of young plants, so consider keeping them indoors longer if you can.- For germinating: Make your life easy and start them indoors in a plastic growing tray with a clear lid (to keep in humidity) and a grow light. I scheduled my grow light to be on 14 hours a day and had it at a moderate distance (pendant light hanging 2.5 feet above the tray). I’m sure a sunny windowsill would work for people with bright living spaces, but my apartment is dark. You can probably also use a lot of other setups with common household items to avoid buying a Jiffy tray/peat pot kit. An old aquarium would work, and even a storage bin or plastic lunch tray with thin layer of peat moss or coir and loose saran wrap cover might work. If you do use peat pellets, keep in mind that I noticed the off-brand ones mold over QUICKLY (within a day) if you leave the humidity lid or cover on for even a little bit too long. Also, don’t try growing larger plants in the same tray/batch with the moss—even lupine and poppies will sprout and shoot up extremely fast by comparison. You’ll need to remove the lid for them to continue gaining height, while the moss might have preferred an extra day or two with higher humidity of the lid. They love moisture, but if you just add extra water to the drip tray to the point of them being water-logged and having standing water, it forms algae quickly. There’s a balance of keeping them damp but not soaked—you’ll figure it out. If you’re afraid of overwatering the tray and can’t drain it easily, get out a squirt bottle and start misting. Once you have sprouts, keep the lid off permanently as long as they’re situated in a place without drafts. (If you use a windowsill but then have the window open for ventilation at night, I’d consider putting the seedlings in a bathtub overnight.)- For getting new plants established:Mature plants are hardy, young ones are fragile. Seems obvious, but it’s more true of these little guys than others. Even with daily watering, misting, and lovingly putting mulch around them, 80% of my moss plugs died or diminished over several weeks when I had rushed to plant them. The summer heat was just drying out seedlings too quickly, despite the location being out of direct light.Instead, I started putting the seedlings into intermediate pots/containers with potting soil and setting them on my front porch for a few weeks before planting. They’re still exposed to heat, wind, cold nights, etc. and are just a few feet away from where the other ones died, but they can retain moisture much better in a little pot. I do not go through a hardening process with them, they just go outside and are fine as long as you don’t skip a day watering.Oh, and one day out in direct sun? They’re dead. I had put a very healthy plant in a container with some pumpkins and false shamrock—as long as the leaves of other plants shaded the moss and I watered that container daily, it thrived, even in extreme heat. The second I rotated the container to move it out of a walkway… The moss was exposed to direct sunlight and it was brown and dead within a day.Likewise, I tried breaking off clumps of my established plant, hoping to hasten the spread. Instead, most of my clumps died. They’re simply too fragile to break apart and stick back in the ground, even in the right conditions. It seemed infuriating that the established plant is SO sturdy by comparison, but it is what it is.Another issue was watering the young plants with a stream of water that was too strong (again, NOT an issue with the mature plant—that thing could be pressure washed and be fine). The garden hose pulverized a few moss plugs, even on a gentle “Shower” setting. Only use “Mist”. Even the watering can was too harsh. I started a new system of planting around a flat rock, then watering only the rock. Let the water run off in all directions to get the soil wet. For containers, only water the dirt around the edge of the pot.From now on, I will keep growing the young plants indoors with the grow light for another month or two. Because I wanted reclaim my kitchen space and rushed the first batch outdoors, I had worse results. Now I’ve got a system down and look forward to the moss takeover of my neighborhood…===========

I purchased enough of this seed to cover 400 square feet of ground. I only needed to cover 20 square feet. I followed all the instructions to the letter. I was doing this job for a client. My reputation is impeccable and I would like to keep it that way so now I am in a position where I need to refund all the money for this job to my client because NOTHING grew from this seed. I noticed that several others have the same complaint. Why then are you still carrying this product on your site? I am a very qualified Horticulturist with over 40 years of experience and have dealt with minute seed in the past on reclamation projects. I am very embarrased by this outcome and would NOT recommend this product to anyone.
