Protect Your Plants From This Week’s Freeze

ice_storm_047

The National Weather Service in Sacramento has issued a freeze watch, which is in effect from late Tuesday night through Thursday morning (Nov. 23-25) for the Sacramento Valley, Delta and northern San Joaquin Valley.
Overnight minimum temperatures are expected to range from the upper teens in the coldest outlying areas to the mid to upper 20s in urban locations. Durations below freezing of up to 8 hours or more will be possible in the coldest areas. Coldest readings will be in the outlying areas generally along the east side of the valley.

Damage to unprotected outdoor piping will be possible. Temperatures at or below 28 degrees can damage ripening citrus. Temperatures at or below the mid 20s this time of the year can damage nut trees, especially walnuts, since the trees have not yet hardened for the winter.
A freeze watch means sub-freezing temperatures are possible. These conditions could kill crops and other sensitive vegetation. Protective measures should be considered.
Please refer to the Colorado Master Gardener publication, Frost Protection and Extending the Growing Season, posted on the public Shasta College Master Gardener website at http://groups.ucanr.org/Shastamastergardener/files/79992.pdf, and share this information with your friends, neighbors and interested public.
Good luck with your plants, pets, and pipes this week.
