How Do You Protect A Lemon Tree During Winter?
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.
What To Plant Under A Lemon Tree
Companion plants with shallow roots are ideal for stand-alone lemon trees. However, do not grow other greeneries alongside the potted shrubs. Crowded root spacing hampers the development of lemons.
Here are a handful of plants to attract bees and repel pests.
- Annual or perennial alyssum
