Where King Alexander Palm works in a SW Florida yard
King Alexander is a focal palm: one double at an entry, a pair flanking a driveway, or a row 10 to 15 ft apart along a long approach. The clean green crownshaft and smooth gray trunk look good against a house wall or tropical underplanting.
Keep it a few feet off the roofline and away from the pool deck, since it drops fronds and red fruit. Underplant with Bromeliads, Ti Plant and Ornamental Ginger.
- Instant entry statement
- Driveway and walkway rows
- Courtyard focal palm
- Tall tropical backdrop
How our crew plants it
Field-grown palms come with a root ball, so the hole is twice as wide as the ball, and the top of the ball sits level with the soil, never buried. The palm is braced for 6 to 12 months and watered in well.
Water daily at first, as the new-planting allowance in Lee and Collier permits, and keep the root ball moist while roots re-establish.
Care after planting
- Fertilize three times a year with an 8-2-12 palm fertilizer with micronutrients, timed outside the June 1 to September 30 nitrogen and phosphorus ban in Lee County, Naples and Marco Island.
- Yellow or orange spotted older fronds mean a potassium or magnesium shortage, and frizzled new fronds mean manganese, which palm fertilizer with micronutrients corrects over time.
- Prune only fully brown fronds and never cut green ones, since it is self-cleaning and most old fronds drop on their own.
- Water regularly, especially in the dry season, because this palm sulks when it dries out.
What to watch for
- Cold and salt are its weak points: a freeze near the mid-20s can kill it and salt spray burns the fronds, so avoid open inland lots and the water's edge.
- Dropped fronds and bright red fruit make a mess near a pool or patio.
King Alexander Palm questions we hear
How tall do King Alexander palms get?+
In a typical yard they reach 20 to 25 ft in the years you will care about, and they keep climbing with age, often to 30 or 40 ft. Crowns spread 10 to 15 ft. The field-grown sizes give you much of that height on day one, so check overhead lines and the roofline before choosing the spot.
Can King Alexander palms handle cold in SW Florida?+
They are cold-sensitive. Fronds scorch in frost, and a hard freeze near 26°F can badly damage or kill them. Coastal Cape Coral, Fort Myers and Naples are usually safe, while Lehigh Acres and North Fort Myers are riskier. Skip open, frost-prone spots, and cover young palms on frost nights.
Is a King Alexander palm the same as an Alexander palm?+
No, they are different palms. King Alexander is the large Archontophoenix with a big crown and a smooth gray trunk. The Alexander palm, also called solitaire palm, is a smaller Ptychosperma. Check the botanical name when you compare quotes or sizes.
