Cold-hardiest yearlong greenery
Needle Palms are slow growing, glossy-green palms that make eye catching specimens. They are extremely low maintenance and adaptable, a fantastic choice for novice or lazy gardeners.
This Georgia native conveniently withstands short temperatures drops down to to 0°F, and is composed of fan-shaped fronds that are glossy dark green and silvery on the undersides. The palm gets its full bushy look from its fronds that are split into long divided segments, atop multiple short, stubby, fibrous wrapped trunks.
Needle Palms grow very slowly at a rate of 5 inches per year. They form a clumping habit, growing wide and tall at the same time. They slowly reach a mature height and width of around 6 ft, with large fronds that split into 20 inch long, deeply divided thin segments resembling needles.
Needle Palms hold the distinction of being the cold-hardiest palm out there, tolerating sustained temperatures down to 10° F and short dips to 0° F. They are drought tolerant, thriving in both dry and constantly moist soils.
Needle Palms are perfect for most locations, from poolside areas that are too wet for most palms, to arid xeriscapes.
Undoubtedly, Needle Palms are the hardiest, easiest palm to care for-ensuring yearlong greenery with minimal effort.
Q: How cold-hardy are Needle Palms?
A: Needle Palms are the most cold-hardy palms in the entire world. They can comfortably withstand temperatures down to 10° F, and tolerate short dips to 0° F.
Q: How fast do Needle Palms grow?
A: Needle Palms grow at a rate of 5 inches per year.
Q: Can I plant a Needle Palm indoors?
A: Yes, with direct sunlight if possible.
1. Sunlight
Needle Palms tolerate full sun to partial shade. If your location is hot and dry, especially in the summer, your palm will appreciate a location where it receives some shade during the hottest portion of the afternoon.
2. Water
- For the first month, water twice a week. After it is established, water once a week unless it rains.
- Watering needs to be thorough to make sure the bottom roots receive water at every watering.
- Space out watering sessions so the roots are able to dry.
- The amount of water needed per palm per watering session is equivalent to the volume of the planting hole that was dug for each palm. This amount may range from 2 gallons for small containerized material to 15 gallons for larger palms.
- Plants in a container need more constant watering than those planted on the ground.
- Overwatering or bad drainage can cause permanent damage to the roots over time.
- Placing mulch over the roots can help with water retention. Use caution not to allow the mulch to touch the base of the palm, otherwise it can cause rot.
Seasonal watering changes
Depending on your geographic location and the intensity of the season, you may need to adjust watering accordingly:
Winter: (60 degrees or less) no need to water, except for the first 30 days after installation.
Spring: (75 degrees or less) Once a week.
Beginning of Summer: (90 degrees or less) Twice a week.
Heat of Summer: (90 degrees and above) Three times a week.
3. Fertilization
Needle Palms can be fertilized in early Spring and late Summer. Use a general purpose blend specific to palms, and be sure to follow the instructions on the label.
4. Soil
Needle Palms grow naturally as understory palms in wet, woodland areas, making them able to tolerate soils that are occasionally wet for longer periods of time. However, they do best when placed in well-drained soils that are rich in organic nutrients. To help the soil drain better, combine 70% soil with 30% coarse sand.
5. Pruning
Needle Palms hold their green fronds longer than the vast majority of palms, meaning you might not have to prune off a dead frond other than every couple of years. However, when you do prune them make sure to wear gloves because of the long, needle-like blackthorns located at the base of the fronds.
6. Winter Care
Protect fronds with a frost blanket if temperatures falls below 10°F.
