Collapse ▲Dear all,
Over the weekend many of you contacted me with the same question: ‘What should we do, we are in full bloom?’
The exceptional warm weather over the second half of February started the season in NC and most other places in the Southeast very early. It is hard to predict how the weather will change over the next few weeks, but if we look at recent springs one thing becomes evident: The risk of frost or freeze events is not over.
An early bloom like we see right now inherits several risks:
(1) Your market is not ready for the amount of strawberry you might have and you might not be able to sell your fruit. (2) If you start fertilizing now, you might push your plants in an early production and you won’t produce at the usual peak season as expected. (3) If you chose not to pull flowers or pick fruit, leaving fruit on the plant will increase your disease risk significantly for later in the season. (4) There is still a high risk of a frost or even a late freeze event which would lead to intensive protection measures and potential loss of fruit.
My recommendation is simple: I wouldn’t risk it.
I would not start fertilizing for probably another one or two weeks, unless you know you have the market to sell. I would probably pull the flowers rather than letting them develop. Also, please leave the row covers in your field until the risk of cold injury is over.
Temperatures will stay in the upper 30s/lower 40s as minimum and upper 60s maximum for this week (see Figure 1 and 2). However, we are at the end of February and there might be some cold nights or even days ahead of us.
