I need to add soil to my Strawberry bed. It was new 2 years ago and the soil has settled and the plants are now low in their raised bed and I fear they are not getting enough air/light. My question is when is the best time to dig them up, add soil, and transplant them? They are mostly June bearing and a few in the upper tier are everbearing. Also, can someone tell me the best soil mixture to add to their bed? I will edit to add a picture of my Strawberry bed when I can find the photo. Thanks in advance. Jeanne (gardenglassgems)
