I have an old bed of Seascape strawberries that has been taken over by weeds. It is a raised bed. I took all of the strawberries out and was going to put them back in after I took care of the weeds. Then I read that strawberry plants lose production after a few years and should be replaced with new plants. These plants have never really been good at sending out runners, so I do not have many young plants. The plants I have look like they have old crowns. Should I put those back in or should I purchase new plants? If I purchase new plants, does anyone have suggestions on varieties that are sweet and juicy. I would like a few berries all summer long, so everbearing would be best. We have enjoyed the Seascape but the berries have been rather small.
