Our most moisture-retentive bonsai soil mix NOW CONTAINS UK PRODUCED BIOCHAR.

Composed primarily of small grain aggregates and finely graded British conifer bark. This soil mix offers a free-flowing lightweight fibrous and air-filled environment perfect for the development of fine rooted species. Suitable for indoor and outdoor bonsai that need above-average levels of moisture in summer. Species that require a lot of water during the growing season will love this mix. Also if you can't manage to water as frequently as you would like in summer this fine-grained compost will keep your trees happy for longer periods between watering. Use straight from the bag, no sieving is required.

It has taken Graham thirty years to perfect our unique soil mixes, a process that continues every day. It's possible that a third or more of the bonsai trees in the UK are planted in our soil products, we sell hundreds of tons a year. We don't sell hastily composed mixes that are untested. Please respect this effort and dedication and don't ask for the recipe.

"After spending the last 18 months experimenting with Kaizen soil mixes….I have to say I’m mightly impressed with all the varieties I’ve used.

 Just done a repot of 4 young Japanese larch trees…..One was previously potted 12 months ago with Kaizen No: 1 …another with No: 2….3rd with Akadama ….and the forth with another heavily organic mix that I purchased elsewhere a few seasons ago.

The growth and quality of the tree roots that have been in Kaizen mixes looked outstanding compared to the others that were not!

Generally speaking all my bonsai that went in Kaizen mixes have done extremely well with healthy vigorous growth." S.P - UK

Amazing and luxurious
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
My daughter said this blanket can be described as luxury. It is soft, plush, and warm. It does slip and slide some, so just be aware that it can do that

Super soft, looks and feels lovely
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
LThis is a double sided faux fur blanket (with sides have the same slightly bubbled fur. It iz slightly bubbled looking, not as bubbly as the picture makes it seem. The two sides are sealed around the edge, but not sewn or tied in anyway throughout the blanket, so the two sides are free to move on theinside of the. Blanket. It is extremely soft, and my dog, who is old and going blind actively seeks out this particular blanket to make his nest in. He loves it, and so do I. I got it discounted in white, a d know at some point it won't look white any.ore. I'll try to die it after it gets a little grungy looking. Till then, it looks and feels luxurious. I only wish it were joined together in the middle, and more "bubbly" looking. It's a bit heavy by itself for summer nights, but feels warm down cozy in colder times. I got the throw size, it seems a bit smaller than I expected it to be.

Warm and cuddly!
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
I love this double sided blanket!! It is sooo soft and warm. I got the creme color. I don’t understand the reviewers that say that it is hard to fold or that it slips against itself. Mine has two edges/seams that are sewn well and it’s simple to fold after use. I just look for the tag which is on one seam and fold from there. Great buy too!!

Super soft, cozy, and a beautiful addition to the bed
Color: Khaki, Size: Queen(90×90in)
This blanket is absolutely beautiful and feels just as good as it looks. It’s incredibly soft to the touch and has that warm, cozy feel that makes you want to curl up right away. The texture adds a nice touch without being too heavy, and it lays really nicely on the bed. My daughter immediately claimed it for her room and has been loving it ever since—it’s quickly become her go-to blanket. It also seems very well made and holds its shape nicely after use. Overall, a great mix of comfort and style.
