Queen Palm Care

Syagrus romanzoffiana

General information
A moderate growing palm for full sun or afternoon shade that grows to about 25 to 30 foot tall, with a 12 to 15 foot wide canopy. They are cold hardy to between 28 and 25 degrees F. Regular deep watering in Summer is required to keep fronds looking their best and applications of potassium, manganese, and magnesium soil amendments as well as other trace elements are required to maintain health. In addition to their fertilizer requirements in our soil, they may also need to be treated with fungicide to prevent bud rot in the crown of the tree. Queen palms do provide an elegant accent to a tropical or formal looking landscape. Also, they look great around pools, grow especially well in lawn areas, and are very clean.

Fertilizer Requirements:
Follow all manufacturers' instructions for the handling and application of fertilizers. Fertilizers that contain metal ingredients will cause staining of concrete, gravel, stone, and porous surfaces.

Application Area:
Apply fertilizers and soil conditioners to the soil in a large ring at least 2 foot from the trunk to beyond the perimeter of the canopy. Fertilizers and soil conditioners work best if they are turned into the top 4 inches of soil immediately after distributing. The larger the area for the application of fertilizer immediately followed by the correct, heavy application of water will result in a reduced chance for chemical burn to the fronds of the queen palm.

Dispersul™ (Soil Conditioner):

When: First Half of February, First Half of May, & Second Half of August.
Rate: Trees less than 6' tall = 5 to 8 cups per tree per treatment.
Trees 6' - 10' tall = 8 to 12 cups per tree per treatment.
Trees 10' - 15' tall = 12 to 16 cups per tree per treatment.
Trees taller than 15' = 20 cups per tree per treatment.

Apply a slow & thorough deep watering to area of treatment immediately after application.

Treeland Nurseries General Purpose Fertilizer 16-8-2:

When: Second Half of February, Second Half of May, & Mid-September.
Rate: Trees less than 6' tall = 1/2 to 2 cups per tree per treatment.
Trees 6' - 10' tall = 2 to 4 cups per tree per treatment.
Trees 10' - 15' tall = 4 to 6 cups per tree per treatment.
Trees taller than 15' = 10 cups per tree per treatment.

Manganese Spikes or Manganese-Sulfate 31%: Apply with General Purpose Fertilizer.

When: Second Half of February & Mid-September.
Rate: Trees less than 6' tall = 2 spikes per tree per treatment.
Trees 6' - 10' tall = 4 spikes per tree per treatment.
Trees 10' - 15' tall = 6 to 8 spikes per tree per treatment.
Trees taller than 15' = 8 to 10 spikes per tree per treatment.
Apply a slow & thorough deep watering to area of treatment immediately after application to prevent burning.

Fungicide:
Bordeaux Mix fungicide is the most cost effective and reliable fungicide available for the treatment of bud rot (also called crown rot) in queen palms. It is easiest to apply Bordeaux fungicide for the prevention of bud rot; however more applications will be required for the treatment of queen palms that are already infected.

Preventative Applications:
When: Apply in November, February, and June.
Mix thoroughly 4 to 8 Tbsp. Bordeaux Mix to 1/2 gallon water, then pour mixture directly into the crown (the area where new fronds emerge) of the queen palm.

Remedial Applications:
When: Apply in November, February, June, and August.
Mix thoroughly 8 Tbsp. Bordeaux Mix to 1/2 gallon water, then pour mixture directly into the crown (the area where new fronds emerge) of the queen palm.

Pruning:
The healthiest times of the year for pruning queen palms is September through October (which removes Summer damaged fronds) and March through mid-May (which removes frost damaged fronds.) Remove only the minimum amount of fronds to keep a nice look to queen palms; excessive pruning to queen palms can result in stress and disfigurement to the plant. Remove old fronds with an arbor saw at the base of the leaf stem just above where the stem flattens out to attach to the trunk of the queen palm. Old leaf bases can be removed when they are completely dried out by pulling them off the trunk or by using a utility knife at a shallow setting to cut them off the trunk. Make certain to not cut into the trunk of the queen palm with the knife blade.

If you have further questions regarding queen palms, please do not hesitate to ask for assistance.
