Buyer’s Guide
Size. First of all, pay attention to the size of the pebbles. Small stones are suitable for small plants, as their root system is much thinner. Larger pebbles should provide moisture and air for large roots.
- Color. In fact, it’s not just about beauty. Natural clay has a rich, bright red or brown hue. Lighter colors indicate the possible presence of impurities.
- Structure. You can touch the balls before purchasing them. Make sure the clay doesn’t crumble or break. A structure that is too porous wouldn’t be able to hold moisture, and your plant is at risk of rotting.
- Dust. Good pebbles usually don’t breed dirt. Of course, you will get some dust after work, but after each watering, you shouldn’t clean up the whole clay carpet around the flowerpot.
FAQ
Q: Can I use pebbles outdoors?
A: Yes. However, be sure that the condition of the pebbles will be affected by the amount of precipitation and humidity. In arid regions, pebbles are a lifesaver for moisture retention. However, if the air humidity in your area is sufficient for plant growth, pebbles can induce rooting.
Q: What size pebbles are suitable for an orchid?
A: Usually, you need not very small pebbles, about 0.7-10 mm in diameter. The orchid, despite its small flower size, has a fairly big root system. Therefore, the roots need more air.
Q: How often should the pebbles be changed?
A: In general, the product can serve you for a long time. You can even use the same shingle for several years. But each product is unique. If you see that the stones have begun to burst or crumble, it’s time to change them.
I really like these GEOLITE pebbles. The cost is great, and I truthfully don’t care about the perfect roundness of them like others do. Some people also seem to want the bright red, but I like the darker more natural color anyways.
