Wouldn't the substrate just wash right out the the laundry basket when he watered it if there wasn't something holding it in?
No, I meant like dirt substrate. I was saying why don't you use sphagnum to line the basket then fill it with the better coarse substrate that won't become paste like the sphagnum, or would mesh be better to cover holes?
Am I being confusing?
And also if you line the outside of it with sphagnum it kinda blocks airflow into the soil.
JM, that doesn't make any since. It couldn't stop air flow that would harm the plant because it is IN sphagnum.
A very interesting thread
I am in the process of repotting my rajah plants & have been considering other mixes. To date I have used LFS and Seramis Clay pellets with orchid bark. I agree that all Nepenthes do best in as open a mix as possible- far bigger pitchers and much better root systems.
I have read about cedar/redwood mulch being excellent but wonder if I could find it in the UK? How is it packaged- garden centre/orchid nurseries? If that was not available what would you use?
Phil- How deep was the root system on your large rajah, as I have read that they are often quite shallow but spread a long way. Your loss sounds like everyones nightmare
I know that it is always a nerve wrecking business repotting large and older plants you have had many years- Do you or don't you and whatever you decide can seem the wrong decision!
Did you support all the pitchers as I guess most grew well beyond the container they were growing in?
Redwood is normally sold in plastic bags in the garden center outside here in the states. I just got done repotting many of my plants in a treefern/firbark mix from tropical plant products. Now I just potted them so I am not totally sure how they will do in the long run, but treefern lasts a long time.
My N. rajah was growing in a 14 inch wide by 12 inch deep pot of pure LFS and the root mass filled the entire pot from top to bottom. I had a layer of polystyrene packing peanuts in the bottom of the pot for drainage that the roots had completely encompassed. It was inevitable that I was going to do damage but had no choice as the sphagnum was going bad and had that awful ammonia smell forming in it.
I never needed to support the pitchers. The leaves were each 16 to 18 inches long with tendrils that stretched out about 20+ inches long. The pitchers all formed once the tips of the tendrils touched the ground surrounding the base of the pot.
And now if you'll excuse me...I'm going to sit in the corner and cry again!
