We re considering installing Foxtails on a streetscape.Is it acceptable to install Foxtail palms in plastic containers [ ~ 1 M diameter and 1 M high with bottom cut out for drainage ] in order to slow their growth and to control maximum height they will grow to ? The container would be installed below grade so as to be out of sight. For example , will a foxtail 4 – 4.5 M high installed in a pot grow to a maximum height of 8 – 9 M …less than normal maximum height of 10 M .?How much slower might they grow ? Is this an acceptable method of installation or might there be issues regarding the health of the palm? The reason for this question is the objective is that on full maturity their canopies will not affect sight lines.
This is not a recommended planting solution.
If the mature size of these palms does not meet the needs of your landscape, it would be best to choose other another palm or plant for your area.
Check with the County Extension Office in your region. They will give you a list of palms or trees for your region.
