Everbearing/Day-Neutral Strawberry Renovation
I am in the midst of finishing two 5x9 raised garden beds connected by an in-ground perennial bed containing an espaliered row of fruit trees surrounded by chives/garlic and bordered in the front edge by a row of strawberries. I have planted Tristan and Loran day-neutral/everbearing strawberries (sources vary) at the edges of the raised beds, thinking that they won't put out many runners, and have a mix of june-bearing strawberry crowns to go in the in-ground row.
I'd like to renovate these patches to keep them producing for many years, but keep reading that day-neutral/everbearing strawberries are simply replaced every three years after production drops off and no "renovation" of the bed with new young plants is practiced. No one seems to state the answer to my question..."Why not?"
Everbearers/Day-Neutral varieties put out few, if any runners...understood. But, isn't it likely that when production drops off in the third year, a few of those elusive runners can be potted up and stored in dormancy to plant out the following spring (i.e. replacing the mothers with young daughters)? Isn't cloning (albeit in a sterile environment) the way that commercial growers propagate the "new" mothers anyway?
In a related question, I've seen many people post in this forum that strawberry beds should be renovated with newly purchased plants. If there is no indication of disease in the current bed, is there a disadvantage to using propagated runners to rejuvenate the bed beyond the extra effort?
Am I missing something? Why not renovate day-neutral varieties every three years with daughter plants? And besides disease being carried to rooted runners, is there a downside to propagating your own daughters for renovating a bed?
