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.

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
