Chicken grit is excellent for drainage! Thumbs up Grower's size (yes, what they feed chickens Big Grin ) is perfect for containers. You can get bags of chicken grit at your local farm store, but I'm not sure about buying in bulk.

I avoid peat-based potting mixes for my semps. Granted, my winters are much warmer, but I have some that have lived in a coir hanging basket for years in a pine bark/perlite mix.

In the ground, they do really well for me when pine bark is mixed with clay soil.

The problem I have with semps in-ground is that zoysia grass that surrounds the bed invades the area and swallows up the semps. Sad It's a constant struggle to keep the zoysia grass away.

Great information ssgardener. Sorry about the zoysia grass, I understand that can be a real problem.
