Facts about Palm Leaves
Palm leaves grow in a pinnate, palmate, bipinnate, costapalmate, or an entire leaf structure. The leaf size highly varies depending on the species, but they generally take 3 to 5 years to reach the maximum size. They are used to make biodegradable products, woven baskets, garden mulch, and nutritional feed. Trimming is recommended to enhance the look of Palm leaves. They are vulnerable to damage by Palm aphids, Palm weevils, lethal yellowing, Royal Palm bugs, and Fusarium Wilt.
Introduction to Palm Trees
In the old days, Palm Trees were mainly used as shade in the desert and as a food source. But in modern times, they have many uses, including landscape designing, interior decoration, and food recipes.
Palm trees had their significance in ancient civilizations as well; Christianity, Judaism symbolizes it with peace, whereas the Romans use it as a sign of victory.
Palm trees are actually small shrubs, or woody vines called the lianas. As the plant matures, the trunk does not spread in width but only grows upward to increase height. Unlike other trees, the Palm trunk does not develop rings as it matures.
These are durable plants that take about five years to grow the trunk. Some of the species can live for centuries.
Palms are the most exotic yet recognizable species on the planet. They are admired for the large and unique foliage or fronds. Many varieties produce fruits that vary in size, shape, and structure.
There are 5 subfamilies in the Palm family distributed in tropical and subtropical areas. Palms are evergreen plants; therefore, they retain the green-colored leaves throughout the year.
They are used in a range of climates to decorate roads, parks, and outdoor gardens. They can transform your backyard into a tropical garden.
Some popular Palm varieties are mentioned below.
Date Palm – it is a fast grower. The Date Palm is closely related to the history of the Middle East. It served as a source of food energy, sheltered people from desert winds, sun and supported agriculture production. This plant is also known as the Tree of Life.
Coconut Palms – did you know that this variety keeps producing the fruit until it reaches the 80th growing season. This variety is admired for the fruit (coconut) and massive frond size. In outdoor locations, the fronds can easily spread 30 ft. (9m).
Needle Palm – this is the hardiest variety of Palm trees. It comes from the United States. It got its name from the needle-like spines. This small plant grows only to a height of 10 ft. (3m).
Foxtail Palm – this plant is high light species because it grows in direct sunlight. It is famous for the small reddish-orange fruit and the large leaves. The majority of the Foxtail Palms are found in Australia.
Royal Palm – this one has a royal appearance just like its name. It is decorated with bright green fronds and white flowers.
Lady Palm – this is the smallest Palm tree. It grows anywhere from 6 – 12 ft. (1.8 – 3.6 m).
Chinese Windmill Palm – this variety can withstand snow and cold under special conditions. It is cultivated in cold areas like Sweden, Canada, and Vancouver.
Coco De Mer Palm – this is the most unusual variety of Palm trees. It has the largest seeds, and each seed can weigh about 15-30 kg. This seed can take 6-7 years to reach maturity and about 2 years for germination.
Quindio Wax Palm – This is the tallest variety of Palm. It can grow up to 197 ft. in height. It is the national tree of Columbia and originates from Peru and the Andes of Columbia. In its native land, other animals use it as a habitat. One prime example is the Yellow-eared parrot.
Several varieties of Palm trees are threatened by habitat destruction, urbanization, mining, and wood chipping.
Each part of the Palm tree can be used in some way. Some basic uses are listed below.
- The ripe, edible fruit from Palm trees is used to make desserts and other food recipes.
- Palm water is used to make wine or sugar.
- The strong trunk of Palm trees is utilized to make furniture and boats.
- Palm roots have medicinal uses.
Uses of Palm Leaves
Palm leaves are usually called fronds that are uniquely shaped and sturdy. On average, a Palm tree can produce 13-20 kg of dry fronds every year. These leaves are durable and have several uses.
- They are used to make traditional woven baskets and hats.
- They are used as a nutrition feed for livestock/animals.
- The leaves are harvested in the summer months to make wax or oil.
- It can serve as fuel for fire during outdoor cooking.
- These leaves serve as an accessory for bouquet arrangements to add a touch of greenery.
- The leaves that fall naturally are used to make Palm leaf plates, serving dishes, and bowls. These are 100% biodegradable and natural. These products can be later used as organic fertilizer.
- The pinnate leaves are used as a roof for huts or garden fence. If you use them in your outdoor garden, they can create an inexpensive weather shelter for other plants.
- Palm leaves can be used as mulch for garden beds. But remember, it will decompose at a very slow rate.
Growth of Palm Leaves
Palms are very diverse in terms of leaf size. Most varieties have medium to large-sized leaves. The shape of the leaves also varies; some are elongated while others are broad.
The color of the leaves will vary depending on the cultivar, but most young leaves are waxy green on the top and greyish brown at the bottom. As the plant matures, the leaves vary in hues of light and dark green and grow in an alternate or spiral pattern.
Palms mostly grow leaves in a cluster. Each cluster has a bunch of small leaves.
The leaves can form a crown on all sides of the stem or just the tip of the stem. Palm leaves have a tabular sheathe at the bottom that opens once the leaf is mature.
New leaves grow from the bud or the heart of the Palm as a big stick or vein. This vein has a pointy appearance but unrolls itself once the leaf is fully grown. The area where the frond emerges is called the cabbage.
This can take one day or one week, depending on the environmental conditions and variety you are growing.
The leaves of a Palm tree play a major role in plant health. They collect all the necessary nutrients and moisture content from the atmosphere. They also help in the identification of Palm variety.
The long green fronds can take 3-5 years to reach maturity. The new leaves always grow from the top of the Palm crown, which ensures the old leaves stay at the bottom. The young leaf is attached to the trunk via a petiole.
The Palm tree will shed the old leaves, or you will have to perform pruning to encourage leafy growth. Each Palm frond has a distinct growth habit, but most varieties grow at regular intervals in an arching pattern.
The fronds can be either glossy or matte, and even the thickness of the leaves can vary. The leaves are beneficial for the Palm tree even when dead as they are utilized for nutrition.
Shapes of Palm Leaves
Almost all Palm trees usually grow spiky, green-colored fronds; they are differentiated only by the leaf shape or structure. The hundreds of Palm species have five fronds shapes, which represent how the leaves grow.
This shape resembles the feather. Fronds are divided into leaflets that are attached to a single leaf axil in the middle (a thick central rib). This shape is also called standard palm leaf. The variation in size can be anything from 1 ft. to 70 ft. The most economic Palms like Coconut Palm, African Oil Palm, and Date Palm have pinnate leaves.
This shape represents a hand palm or fan. The fronds in this structure have round or semi-round leaf parts.
These parts are further divided into segments but grow from a single point. These leaves are comparatively smaller that can reach a maximum size of 16 ft. only. The leaves of the Mexican Fan Palm are a good example.
These are rare fronds with double pinnated leaves. Each leaflet has its own feather-like shape. Some gardeners say they resemble a fishtail.
Each frond can reach a size of 13ft (length) and 9.8 ft. (width). Fishtail Palm best represents this leaf structure.
These are a combination of pinnate and palmate. The leaves on such varieties are partially pinnate and partially palmate. This looks like an elongated version of palmate leaf. The leaf blades are either round or oval.
Some Palms grow entire leaves that are undivided and simple. This is a rare case, and the leaves resemble pinnate. Only five genera from Palms have this type of leaves.
Pruning Palm Leaves
The exotic Palm Leaves can be pruned to have more growth. But the pruning should be done carefully because, unlike woody plants, the Palm trees cannot recover from injury.
- Make sure you do not damage or remove the terminal bud while pruning. Otherwise, your Palm cannot develop new leaves and eventually dies.
- A well-pruned Palm tree should have a round crown-like leaf head.
- Do not over prune as this will weaken the Palm structure. Unnecessarily removing the leaves can make the plant look unnatural with nutrient deficiencies.
- As a thumb rule, Palm leaves should not be pruned. Instead, you should trim them. Trimming the dead fronds will enhance the look of the plant.
- Only trim the dead fronds and avoid removing the ones that still have some green areas on them. These dying leaves will provide potassium for new growth. If you remove these leaves, the new growth will extract nutrients from healthy leaves at the bottom.
- You should also trim the Palm leaves that are damaged by cold weather or wind.
- Another point to remember is that not all varieties require pruning. Some of the Palms are self-pruning; therefore, know your plant before you start pruning. Royal Palm and Foxtail are self-pruning varieties.
- Gardening tools can easily spread diseases while pruning, so clean all the tools before you start pruning. You can dip your tools in 50% alcohol for about 10 minutes.
Pest and Diseases for Palm Leaves
The Palm aphids, Hempel, and Boisduval, are the only species that infect a Palm plant. They feed on Palm leaves of young plants, especially the Coconut Palm.
These aphids do not resemble the typical aphids we have on our houseplants. Instead, they look like a scale insect or whitefly. It has a white, waxy fringe with a convex body. Adult Palm aphids are about 1-2mm in size and wingless. They are dark brown, but the nymphs are green.
These pests feed on young fruits on the host Palm. They also reside in unopened fronds or the young fronds.
They stay motionless and feed on the Palm leaves for several days. They pierce the green foliage and suck all the plant phloem. The Palm plant will have yellow leaves and decline in vigor.
Aphids feeding can also limit photosynthesis as the sooty mold rests on the leaf surface. Your first line of defense against them is inspecting the new Palm plants. Horticulture oil is an essential material to control the Palm aphids population.
If the younger leaves on your Palm are declining, check them for Palm weevils. During the initial stage of infection, the old fronds will start drooping.
As these pests continue to feed, the fronds start rotting, and eventually, the crown of the Palm falls, creating a popped neck.
To prevent Palm weevils, avoid pruning damage and cultivate your Palms using cultural practices. Remove all the infested leaves to get rid of them because there is no chemical control for weevils.
Royal Palm Bugs
These bugs specifically feed on the young fronds of a Royal Palm tree.
When the infected leaves mature, they have a scorched appearance. You should drench your Palm leaves with a chemical named imidacloprid to control the spread of these bugs.
This chemical application should be repeated for several weeks.
If your Palm leaves have started yellowing and the fruit is also dropping, there is a chance it has lethal yellowing. This is spread by tiny leafhopper insects.
This yellowing cannot be treated, so you have to dispose of the infected Palm leaves or the entire plant.
This Palm tree fungus causes the fronds to lose the green color and wilt. If your Palm tree is infected, it cannot be cured. You should immediately remove the infected areas.
12 Unusual Facts about Palm Leaves
There are interesting facts about the history, significance, and usage of Palm Leaves. Some of them are listed below.
