FlytrapCare Carnivorous Plant Forums

So I bought a "plug" of u.sandersonii. I grated some LFS until it was like sawdust and put it in a pot with drain holes inside another pot without holes. Filled it to about an inch below the plant with RO water. So the plug came today and I just planted the whole plug right in the middle. Was I suppose to split that thing up or loosen it at all? It was a tight wad of roots in what looks like peat.

I assure you, you've done nothing wrong. Utricularia will naturally spread throughout that pot.

U. sandersonii does better for me in waterlogged peat/sand, but Sphagnum should work well too.

I was undecided about the planting medium. Because they are so small I pulverized the LFS...

Based on my experience, it will grow just fine without quite so much water. I use peat/sand but I doubt the plant cares much either way.

U. sandersonii is rather vigorous and should do ok in that. Many terrestrial Utricularia do better (to varying degrees) in peat mixes though.

Whether you split up the plug or not doesn't matter too much - Utricularia actually don't have any roots at all. The white root-like structures you're seeing are the stolons, which are modified stems. The "leaves" are modified stems too, and the real leaves are the traps. Both of these grow directly out of the stolons.

Since the plant is so decentralized, you can basically rip it up a lot and it will still grow as long as there's a decent amount of intact stolons.
