wheee! such rewarding plants to grow!

I have some alpine strawberries ( which are like little white marshmallows!) that grow in semi-wet shade near a bird bath, in thick, dark clay/sandy soil.

I'd say any soil that has god drainage, yet with a decent amount of organic matter will work well.. like 1/4sand, ,1/4 clay, and the other half organic-ness such as small dry twigs, dirt..

You want good drainage in the soil so their is little risk of root rot and other fungal fruit afflictions.. however the varieties you've chosen should be well-resistant to these

Best wishes! Happy salads and cheesecake, hehe
