What is it?

Japanese pumice, or Hyuga as it is known in Japan is a naturally occurring volcanic product from the south part of Miyazaki Prefecture in Japan.

Hyuga vs Pumice

These two products are very similar in characteristics however due to the manner in which this Hyuga is formed in nature it is slightly softer and more porous than conventional pumice. In fact Hyuga is so porous it will sink, which reduces erosion when watering. 

Due to the porosity of Hyuga aggregates in your growing mixes it enhances:

  1. water retention
  2. nutrients
  3. oxygen

It is suitable for a wide range of plant species as it has an essentially neutral pH of 6.

How to use?

Japanese pumice is highly recommended for more demanding succulents as well as acid loving rhododendron (including Azalea), general pot plants, orchids and it of course forms a crucial part of many bonsai growing mixes.

If I had only one soil component to use for bonsai it would be 100% pumice. If you have akadama, add some. - Michael Hagedorn

As Hyuga will not under normal circumstances break down it can be sifted and re-used however if you intend doing so a disinfecting treatment using Sporekill is strongly recommended to reduce the risk of spreading fungal or bacterial issues.

Hyuga can be combined with other elements such as akadama or peat (no more than 20% of the total mix). Due to the good drainage qualities of hyuga it is very often used to assist a sick tree to regain vigor and health. In such a case 100% Japanese pumice may be used.

For typical growing conditions, a ratio of 1(akadama) : 1(pumice) can be used. For plants which prefer more moisture you can double the quantity of akadama.

Spoiled brat approved.
Style: Small 2.6" (6 Pack)
Just received these today so we'll see how long they last. My dog is obsessed with 3 marshmallow toys she has that get pretty grungy. I found these as backups so I could wash her other ones. Well see if she destroys them. Lol. The sqeakers work a little to good if ya know what I mean. I'll probably get sick of them. 😆

Didn’t last long but they had a blast
Color: Octopus Purple & Blue
These octopus squeak and crinkle dog toys were a hit with my two pitties. I had about two hours of quiet out of them before they started ripping them apart to get the squeakers. For this reason, you will want to watch your dog if they are a larger breed. They were super cute when they arrived and are a fantastic price for the fun my dogs had with them. I will definitely order them again.

Cute for a puppy or small dog- not meant for chewers
Color: Octopus Purple & Blue, Color: Octopus Purple & Blue
I bought this cute squid two-pack as Christmas toys for two dogs, and they’re absolutely adorable. The colors are bright and fun, and the crinkle sound inside is very appealing especially to the puppy I was buying for. They are a little smaller than I expected, but I added a photo with my hand in it for size reference. The size ended up being perfect for our 12-week-old Irish Setter/Golden Retriever mix. He loves grabbing the tentacles and flinging it around. It’s easy for him to hold, shake, and carry, which makes it a great puppy toy. I also have a German Shorthaired Pointer, and it’s definitely not big enough or sturdy enough for her, she doesn’t really play with it. But for a puppy or small dog, it’s ideal. The Tupac is ideal, but losing one star just for durability and size.
