Strawberries, tiny and rotting quickly
We recently purchased a home, and the previous owner left us a half-finished raised bed garden. One of the beds has TONS of strawberry plants in it. Unfortunately, I think they are too thick, because the berries were rotting when we moved in, and after plucking all of the rotten berries, I've come to realize they are rotting before they are even the size of a penny.
I am a total strawberry newbie, and have no clue how to go about thinning these to make them grow and produce better. I am not sure what type they are for sure, but I do know that I notice new berries here and there every day to every other day, though the production is extremely low. I check the info card for the berries (that they luckily left), and it says their bloom is in the spring, if that helps. The photo is about a 4 foot by 4 foot square bed.
