I planted some bare root Tristar Strawberries last fall in a raised bed (Zone 7). I planned on letting them grow, picking off flowers / fruit to focus on root development. However, once they started to leaf out early in the spring, they seem to have suddenly stopped growing. I didn't have huge expectations, but strawberries are starting to produce in the area and it seems the plants should be a little bit further along. I have no previous experience with Tristar, only Alpine varieties here and there. Any advice, should I practice patience? Please see photo.
