Roots

Like other citrus plants, lemons possess a shallow and fibrous root system. Its roots spread in all directions and surpass the drip line.

Citrus plants like lemons do not have the same levels of cold-hardy. You can consider methods before planting, such as purchasing the rootstock or cold-resistant variety and choosing the best location. 

Nonetheless, you can still protect it while growing. Even though you can readily transfer shrubs grown in containers, the ones on the ground require different solutions.

To care for a matured citrus tree from cold, perform one or more of these short-term yet practical strategies.

Cover with sheets

Old blankets, quilts, or sacks are handy to sustain the accumulated heat within the day.

Use an artificial heat source

Holiday light strips or incandescent light bulbs offer additional heat for the trees with smaller or medium canopy.

Moisten the bare ground

This method prevents heat radiation throughout the night.

Water the canopy deeply during the frost

It maintains the tissue temperature of leaves and branches, reducing their breakage.

  • Annual or perennial alyssum
  • Bee balm
  • Chamomile
  • Daisies
  • Echinacea
  • Impatiens
  • Lobelia
