This past week three horticulturists spent a day pruning some of the largest palms in the palm dome. We have a geni lift that can extend our reach to over 20 feet. We then can use pole saws to extend up to another 20 feet.
The first palm we pruned was the Desert Fan Palm, Washingtonia filifera. The leaves can grow as large as 3-6 feet across. The petioles which connect the leaf to the trunk can be up to 6 feet. So the entire frond can be up to 12 feet long.
Another palm we pruned was the Princess Palm, Dictyosperma album. The feather shaped leaves on this palm can be as long as 8-12 feet long.
The last palm we pruned was the Queen Palm, Syqgrus romanzoffiana. This is the tallest of all the palms we have in the Palm Dome. The Queen Palm can grow as tall as 50 feet. The fronds can grow to over 15 feet.
We needed to groom the older fronds for both cultural and aesthetic reasons. This also gives us an opportunity to evaluate our insect populations.
