Grow VFT in sand

by manik » Thu Aug 08, 2019 10:06 pm

Peat moss holds a lot of water so I want to try sand only soil to avoid overwatering. What grain size would be ideal? I could buy 0,2 - 0,8 mm (average 0,5mm). Would roots grow fine and won't it compact? Pot size would be 15 cm. If I would use bigger grain size capillary action won't work well.

I grow cape sundew in mostly 0,5mm with a bit of 1mm sand and it seems to be fine.

Only downside I can think of would be it dries out super fast. I don't think putting it in a tray of water would work to keep it watered either, I don't think sand will absorb it up into the pot. That might leave you to top water only but in the heat of the summer that could become almost impossible I would imagine.

Height of capillary rise depends on grain size. 0,5mm grain size rises to 15cm so it would reach top of the pot. 1mm to 8 cm. Fine sand would rise to 50 cm, but maybe it would be to compacted for roots to grow or too wet.

Sand dries out too quickly. You need something moisture retaining.
