5-1-1 becoming hydrophobic
I like the 5-1-1 mix. I've been successfully using it to grow hosta in for many years. What I DON'T like is the tendency it has toward becoming hydrophobic if I allow it to dry out a bit too much. It happens, sorry. Some summers are especially hot and dry, and sometimes I have other things more pressing.
I invested in a DIY irrigation system for all my container hosta. It works well. But if the media has gotten a tad dry between waterings, I find the water just tends to run out the bottom of the container and doesn't really absorb into the mix. Anybody know what I can do to rectify this, other than the obvious solution of NEVER letting the mix dry out too much? One year, I did mix in some of the floor-dry granules to retain moisture, but I found that in the Spring, that could cause crown rot depending on the previous winter. So I'd prefer to stick strictly to the 5-1-1 mix with no additions.
Thanks for any advice.
