Joebonsai Genuine Black Lava Gravel Bonsai Tinyroots-Brand Top Dressing One Pound Great For Bonsai Landscaping/Design Ph Balanced All-Natural

I really like these black lava pebbles; I use them as a top dressing for my succulent's soil and it really makes their colors pop. What's great about these pebbles is that they allow the soil underneath to breath and doesn't trap moisture in the soil because of its porous nature. It also doesn't heat up the spil much because it doesn't trap the heat.Its ground pretty fine, and is comparable to the size of coarse gravel. In my opinion, this is best suited to smaller pots and plants, because of its fine size.The one thing I was a little disappointed in, which wasn't enough of an issue to remove one star, was that the blackness of this rock is due to moisture. Once it's on the soil and gets a little dried out, the color lightens to more of a gray/black, as opposed to black/black right out of the bag. It still has the quality to pop those succulent colors, though, and looks neat and gives your plants a more finished look either way. I've added photos to show how well they work as a top dressing and how they make the colors of the plants pop.Five stars for this item, and I'll def be buying again.

Use this as a top dressing for lithops and other succulents and it works great for that purpose. Love that i don’t need to worry about picking it all off the top when repotting since a little mixed in with my soil is beneficial for drainage and airflow.I do wish the particle sizes and color (ranges from dark black, to light black, with bits of red/brown)were a bit more uniform, and there’s quite a lot of dust, however this is to be expected and a very minor annoyance and one I’ll happily accept for a natural top dressing- definitely beats polished rocks any day!

I think this saved a few of my plants. Small bag and I believe it's aluminum and plastic; I'd transfer it to glass since it's probably absorbent which the plants then absorb and may emit, according to some articles. In any case aesthetically, it's aesthetically beautiful especially with contrasting colored plants like pink or white. It helped with keeping plants warm but not making the soil heavy. What I'm unclear about is of it should go on top or bottom of terrariums. Opinions are contrary. On top of regular plants they looked gorgeous and seemed to make most plants happy. I think the Pothos may not have reacted to it but that could be due to other factors.

This works great. I have several bonsai where the sellers had not put any cover over the soil and the soil would pack down and the water roll off. I used a fork to gently loosen the soil and then placed the lava rock over the soil, just as I have on plants purchased from BonsaiBoy. Packed it down gently and watered. No more water running off😄. I did 4 medium to small plants and haven't even used 1/4 of the bag. Bag is resealable. Great product.

Super fast delivery. This is just what my coffee plants needed. Mixed some into the soil around them and then on top. My plants perked up within a day! Nice flakes of lava rock.

The rock is of great quality for the price, I just thought the individual rocks would be larger than they were. The rocks are small enough you can kind of 'sprinkle' them around instead of placing them individually. This may be what many people need and the photo is not misleading, I just didn't research it close enough.

I don't know why but I feel like I'm doing something really good for my plant when I used this on my bonsai Trumpet Jade and Pencil Cactus plants this weekend. And like I'll be doing that good to it every time I water it. A very happy plant parent. Thanks!

I bought this mainly to use as the bonsai gravel in my 12" x 9" humidity tray. This bag contains enough to fill my humidity tray and I still have about 1/2 bag left. I plan to use some more as a top dressing.+ Holds Moisture+ Looks Great+ Different Size Pieces+ Price/Value+ Resealable Bag- No Cons_Bottom Line_ Yes, I would recommend this to a friend for a humidity tray, top dressing, or both. It looks good, comes with a decent size bag, and holds moisture well.
