The Life Cycle of a Palm Tree

Whether you're trying to propagate a smaller palm plant like an areca palm (​​Dypsis lutescens​​, U.S. Department of Agriculture plant hardiness zones 10 to 11) indoors or cultivate a larger tree, such as a coconut palm (​Cocos​ ​nucifera,​ USDA zones 10 to 12), understanding growth stages can be a huge help. The life cycle of a palm tree is similar to that of any flowering plant (though the initial vegetative stage may be longer than average), and tailoring your care to different growth stages can help ensure a healthy plant.

Germination From Seed

All varieties of palms are monocots, meaning each seed contains only a single embryonic leaf. In nature, the seeds fall to the ground and germinate there, either remotely (with the root emerging from the stem with the first leaf still inside the seed) or adjacently (where the first leaf slightly emerges from the seed and the stem and root grow from there).

If you're trying to germinate your seeds at home, it can be a process of several weeks. When purchasing palm seeds, greener ones are less mature and will take longer, while seeds that are more orange in color are older and will germinate more quickly. However, very old seeds may also struggle to germinate.

To begin the germination process, plant your seeds in a seed-starting mix. Keep your palm seeds in small individual pots with adequate drainage. Seeds need moisture to germinate, so water them regularly. Bright, indirect sunlight and a temperature between 70 and 85 degrees Fahrenheit will provide the ideal conditions for germination. After around two months, most species of palm seeds should have sprouted, although certain seeds can take years.

Growth of a Palm

Once your palm seed has germinated and sprouted (usually at around six months), it can be gently moved to a larger pot. Growing your palm from a tiny seedling into a large plant or tree is a long process, so patience is key here. It will take a couple of months for you to see inches of growth and several years before your plant resembles a true palm. As a palm grows vertically, it will shed its old, dead leaves. This is what gives the palm plant its distinctive scar markings on its stem or trunk.

To help give your new palm plant the best chance at growth, the proper care is required. A bright, warm area with high humidity is ideal. Water your plant whenever the top 2 inches of its potting mix begin to feel dry. If you live in a warm climate, your palm can benefit greatly from spending the summer outdoors.

Palm Plant Flowering

In spite of their name, palms are not actually trees. They don't have wooden trunks, instead growing in caliper. This means they widen their trunks by expanding the tissues already present there.

Palm flowers grow in large clusters called inflorescences but are relatively small alone. These flowers will usually begin to show at the beginning of the warmer growing season. In tropical climates, these flowers can bloom on and off throughout the year. Some palms flower only once in their lifetime, after which new stem growth will start from the plant's base.

Palm Fruit Set

Palms are not self-pollinating, requiring wind, insects or animals to pollinate their flowers. After pollination, their flowers will turn into clusters of fruits. Palm plant fruits typically contain one seed, though there are exceptions. In the wild, fruits drop from the tree and are eaten by animals. The droppings of these animals spread the seeds and begin the process of germination and growth once more.

Life Span of a Palm

In addition to the influence of environmental factors, such as climate, soil and nighttime temperatures, on a palm's life span, it also varies according to species. For example, according to an article by David Byres, a biology professor at Florida State College at Jacksonville, the pindo palm (​Butia capitata​) has a life span of about 80 years. The life span of the betel nut palm (​Areca cathecu​), on the other hand, may vary between 60 and 100 years, says the University of Guam Cooperative Extension & Outreach.
