The pygmy date palm, also known as Phoenix roebelenii, originated in southeast Asia near forest clearings, riverbanks and rainforests. In the wild it is generally found as a single-trunked specimen. However, nurseries typically sell them in groups of two or three as multiple-trunked specimens. As with any palm tree, the pygmy date palm needs regular trimming to ensure it stays looking its best. Trimming, though, should be done in moderation. An overly trimmed palm tree may suffer health consequences.
Prune off brown or yellowing fronds from the pygmy date palm tree. Grasp each frond with a gloved hand and snip it off an inch or two from the trunk with your pruning shears.
Look for diseased fronds. Diseased fronds will have spotting on them--usually brown or black in color. Prune these fronds off in the same manner as the brown or yellow fronds.
Trim off other fronds that are horizontal or lower to the ground for aesthetic reasons. Leave fronds that are above horizontal to the ground intact.
Clean your pruning shears with alcohol before moving on to the next pygmy date palm tree. This ensures no disease is transferred between palms.
