They grow 1 to 2 feet per year to a height of 40 to 70 feet, developing 10-foot wide, silver-blue leaves. New Bismarck palms should be planted in late spring. Plant this stunning palm in full sun if you can, but you can succeed at growing Bismarck palms in partial sun too. Select a wind-protected area if possible, since these trees can be injured in windstorms. Soil type is not critical, and you’ll do fine planting Bismarck palm trees in either sand or loam. Keep an eye out for soil deficiencies. When you are trying to care for a Bismarck palm tree, you will have problems if your soil lacks potassium, magnesium or boron. If a soil test reveals a deficiency, correct it by using a controlled-release granular fertilizer of 8-2-12 plus micronutrients.
Aside from mineral deficiencies, you won’t have much to worry about to care for Bismarck palm trees. Irrigation is important when the palm is young, but established palms are drought tolerant. They also resist disease and pests. You can prune this palm during every season. However, only remove leaves that are completely dead. Cutting partially dead leaves attracts pests and depletes a palm’s potassium supply.
