Banana trees are one of the common trees that come to mind when dreaming of the tropics, but did you know that it is not really a tree? It is the world’s largest herb.
The trunk is composed of the main fruiting stem enrobed by leaves. Still, due to its size, it is commonly thought of as a tree.
How to Grow a Banana Tree
You may plant a single banana plant but you will end up with several – so choose a spot that will accommodate several plants. There are different varieties available, the main difference being their height and leaf color.
The question we get the MOST is “Can my tree produce bananas?” Sadly, our growing season is not long enough to produce ripened bananas. They will set fruit and it is most interesting to watch them change from the flower stage to bunches of small bananas.
Banana plants prefer full sun.
The soil should be well-drained, deep, and organically amended. Slightly acidic soil (5.5 to 6.5 pH) is preferred.
Since banana trees are tropical and hail from rain forests, they need a lot of water and plenty of moisture in the air. They do best when planted in groups rather than as single specimens. Being close together helps them retain moisture in the leaves. Provide 1 or 2 inches of water weekly or MORE (especially during the heat of July and August) and check frequently to make certain the soil stays evenly moist. Make sure they are not over-watered, so you do not develop root rot. The soil should always be moist but not soggy, if possible.
- Temperature and Humidity
Bananas thrive in warm, humid conditions. When temperatures drop, growth slows down, and very cold temperatures cause plants to die back. It is best to cut the plant down to ground level and cover with mulch for the winter. Only in the extremist winters have we lost hardy banana plants due to prolonged below freezing temperatures.
Banana plants should also be fertilized very well. Use a balanced fertilizer once a month. Spread the fertilizer evenly around the plant in a circle extending 4 to 8 feet from the trunk. Do not allow the fertilizer to come in contact with the trunk. Feed container plants on the same monthly schedule using about half the rate for outside plants.
Elements your palms need to stay healthy
Applied in correct combination; magnesium, iron, and manganese will keep fronds from yellowing or curling. How much and when depends on where you live.
Here in East Texas, a bag of 8-8-8 is sufficient in keeping your palms healthy and happy!
Steps to establishing a new palm:
- Water plays huge role in establishing a new palm. Water every day for 45 days until the risk of transplant shock has passed.
- Apply the fertilizer away from the base of the palm, staying around 18″ away from the base. Banding fertilizer around the base of the palm tree is considered a poor practice because it can damage the roots.
- Wait about 4 to 6 weeks after planting to fertilize.
Fertilizing palms DO’s:
- Thoroughly read the directions on the fertilizer bag.
- Water BEFORE AND AFTER fertilizing, especially when using a quick release material. Under-fertilize rather than over-fertilize.
- Under-fertilized plants just don’t grow as fast; over-fertilize them and they may die. Pick a fertilizer with an approximate NPK ratio (like an 8-8-8).
- An ideal palm fertilizer has the right mix of microelements, magnesium and calcium.
- Fertilize your palm trees three times a year: spring, summer, and fall.
- You can also augment with organic fertilizers such as blood meal, bone meal, fish emulsion, and worm castings.
- Fertilize completely around the plant, distributing the granules over the entire root distribution area (approximately the size covered by the mid-day shadow of the plant).
- Work fertilizer into the soil if possible.
- Rake the garden of debris, apply their fertilizer, and finish with a top dressing.
- Soil test for salt content, especially in container plants. Inexpensive pronged meters easily tell you when you have problems.
- Keep turf well away from your palm trees. This will make it easier to fertilize your palms and will help keep diseases away from your palm.
Fertilizing palms DON’Ts:
- DON’T fertilize on dry soil, as it can lead to plant burn and death.
- DON’T over-fertilize as this can lead to plant injury.
- DON’T Throw granular fertilizer down the crown of the plant.
- DON’T Throw all the fertilizer in one pile at the base of the plant. Scatter it.
- DON’T Throw the fertilizer against the trunk of the plant in a big pile as this can lead to necrosis or scaring of the trunk.
- DON’T Use the cheapest, highest concentration quick release fertilizers such as ammonium nitrate 30:0:0 (lawn fertilizer), as this can lead to plant burn or injury.
- DON’T Put fertilizer directly in contact with the roots when repotting a container plant, especially if using a quick release fertilizer.
- DON’T Put manure into the hole when planting a palm. Too often the generated heat and solute concentration are damaging to the palms roots.
- DON’T allow rain to fall on your stored bags of fertilizer as this may solidify the granules or leach out the fertilizer. Protect the bags with a tarp.
No, your Sago Palm is probably not dead!
The trunk of the plant is usually not harmed if it undergoes brief periods of below freezing temps.
Follow these steps to prune it correctly and you should see new fronds growing from the center once our weather warms up in April – May.
The fronds that are brownish-yellow will not change back to green – they are dead. Cut them back to the trunk. BEWARE of the sharp barbs that protrude from the trunk. You do not want to suffer a puncture from one of the barbs since it can evolve into a serious medical problem if not treated properly. We suggest using a l
ong lopper to trim instead of a hand trimmer so you are not in close proximity to the barbs. (If you are not comfortable trimming your plants our professional maintenance team can do so for you)
After pruning, new fronds will emerge (flush out) from the crown of the palm once our temperatures warm up enough. Usually once the night temps have reached 70 degrees. You should see 2 -3 flushes during the growing season.
