I was looking at my 3 new pots of sarras while I was watering them and pondering...... We are having yet another heat wave (95ºF to 103ºF) so I am having to do a LOT of watering. I was wondering if it would hurt my sarras any to cover the surface of the soil with mulch? It would be very acidic (shredded hardwood) and would keep the roots cool. But I have never heard of anyone mulching CPs. I'm just trying to think of ways to make the water last longer as I am going broke buying distilled water.
Anyone think a little surface mulch wouldn't hurt?
