Potting Mix
I bought the out the Westland Bonsai Potting Compost Mix for my bonsai, and I really like it. The Seramis granules in this mix are help control how much water my bonsai gets, so I don't have to worry about overwatering and messing up the roots. This mix is made specifically for bonsai plants. With the added wood fibre, it helps the roots. The bag contains 4-litres and was just the right size for my bonsai. Overall, I'm impressed with the potting mix.

Seems good quality… but jury’s still out
Bought the Westland Potting Compost Mix enriched with Seramis (4L) to use with some bonsai seeds. On paper, it sounds great — moisture control from the Seramis, decent texture, and it looks like good quality compost.However… none of the bonsai seeds germinated.Now, I can’t say for certain whether that’s down to the compost or the seeds themselves. I’ve had success in the past with other seeds and different soil, so it’s hard not to raise an eyebrow slightly. But I haven’t tested this compost with anything else yet to be fair.The mix itself looks well-balanced, not overly wet or clumpy, and it drains reasonably well. It certainly seems like it should work in theory.So for now, it’s a bit of a neutral score. Could be perfectly fine. Could just have been dodgy seeds. Gardening can be like that.Three stars. Looks good, sounds good… results still pending. 🌱

Bonsai compost
Perfect for reporting bonsai trees. It has good drainage and doesnt overfeed the tree.
