The Arizona/California desert growing region began a warming trend over the past week with daytime highs peaking February 3 at 85°F. Temperatures will decline through this week but will remain in the upper 70°s to low 80°s, according to a press release by Markon Cooperative of Salinas, CA.
Although the higher temperatures will aid plant growth that had stalled after three weeks of strong winds and morning freeze events, Markon inspectors still expect to see quality challenges through February. In particular, epidermal peeling is expected to increase in iceberg and lettuces such as romaine and green leaf. Other challenges for lettuce and tender leaf items include but are not limited to:
- Dehydration/wilting
- Decreased or inconsistent case weights
- Wind damage
- Epidermal blistering & peeling
- Shortened shelf-life potential
- Yellowing leaves
Markon inspectors continue to monitor desert row crops closely and are working with growers to secure the best product for Markon orders.
