Gardens Grow Longer: More Time, More Pests!
15 Jul
Summary
- Growing seasons in the U.S. are expanding, offering more time for cultivation.
- California gained approximately 47 additional growing days since 1895.
- Extended seasons benefit some plants but favor pests and heat-sensitive crops.
Growing seasons across the United States are extending, offering both opportunities and challenges for gardeners. Analysis reveals that the period between the last spring frost and the first fall frost has lengthened since 1895, particularly in Western states, parts of the Northeast, and some Southern regions.
California leads the nation with an additional 47 growing days, followed by Washington with approximately 40 extra days. This expansion means more time for harvesting vegetables and enjoying flowers. However, warmer temperatures also provide an extended period for garden pests to flourish and multiply, potentially leading to larger infestations.
While some plants may benefit from these warmer conditions, gardeners might need to adjust their planting strategies. Crops susceptible to heat stress or those requiring a certain number of "chilling hours" may struggle. Adapting to these changes involves careful pest management, selecting suitable plant varieties, and adjusting irrigation schedules.
