How to grow Gulmohar in your garden
There are two major ways to grow the Gulmohar tree in your garden. The first is from seeds, and the second is from tree cuttings. Read below and know how to grow the Gulmohar tree: -
The Seed Method
Gulmohar can grow naturally from seeds, and you can also use this method to grow a flaming Gulmohar tree in your front or back yard. Read below and learn how to propagate Gulmohar from seeds: -
Getting Gulmohar seeds
After pollination, a fruit or pod develops. When the pod is young, it is green and becomes brown with age. Then it splits in two, and releases hard brown seeds. You have to get these hard, brown seeds to grow a Gulmohar tree.
How are these Gulmohar seeds?
The seeds of the Gulmohar tree are physically dormant and appear tough on the outside. Without shattering this outer covering, the tree's germination is almost certainly impossible.
Gulmohar seed scarification process
- Before sowing, you have to break the seed’s dormancy by weakening the outer layer through the scarification process. Either use a knife or soak the seeds in warm water for twenty-four hours. Keeping the seeds in water ensures a supply of water and oxygen, which aid in germination.
- By lightly nicking or scratching each softening seed with a knife, you can scarify them, which allows the water inside and hastens the germination process. Some experts or experienced gardeners advise peeling the seeds with a brief touch of sandpaper.
Gulmohar seed germination
The germination period for Gulmohar seeds may last anywhere between 12 and 349 days. If you use the method for breaking the dormancy outlined above, germination occurs in 10–12 days; otherwise, it could take up to 349 days.
- Take a three to six inches deep seed tray
- Fill up the seed tray with a well-draining potting soil
- Plant the Gulmohar seeds carefully
- Remember that each seed should be planted three inches apart and one inch deep
- Pat the potting soil firmly around each seed
At this stage, place the tray in a warm and partially shaded area that will aid in seed germination. Maintain wet but not soggy soil. Within four to six days, seeds start to germinate.
Transfer or repotting
Transfer seedlings that are eight inches tall to a 1-gallon container. Select a good, sunny, and spacious location where the tree can take root and beautify your landscape.
Remember that a Gulmohar tree grown from seeds would require anywhere between 5-12 years to mature before it starts to bloom.
The Cutting Method
- Take a cutting about one foot long with a sharp knife from a healthy Gulmohar tree
- All the leaves from the lower portion of the cutting should be removed
- Dip the stem into a rooting hormone that will enhance root development
- Now take a one-gallon container and fill it with a potting mix
- Place the cutting carefully and moisten the soil a bit
- Keep the container away from direct sunlight and opt for a warm yet partially shady area
- It may take several months for this cutting to grow new branches. Till then keep caring for the tree by regularly watering it.
- Once you see new branches or leaves, take the container to a sunny area
How to Take Care of Gulmohar
Gulmohar trees love bright, sunny weather. At least six hours of daily sunlight are essential.
Place the Gulmohar tree in your garden with lots of space for its root to develop. Also, the location should be bright and sunny.
Clay, loamy, sandy, or gravelly - any type of soil would work for Gulmohar trees as long as it has good drainage quality. The pH range between 4.9 and 10.6 is also acceptable.
You need to water the plant every day in the beginning and keep the soil moist. Overwatering is not a problem, but under-watering can be harmful to the plant, especially when it is young. Water the Gulmohar tree more in the summer and considerably less in the winter. Just ensure the soil dries completely before you water.
Gulmohar likes warm, hot, and humid temperatures. However, Gulmohar trees cannot tolerate drought and frost. It means the extremes of both summer and winter won’t be suitable for this tree. Any temperature lower than 7 degrees Celsius or higher than perhaps 40 degrees Celsius will be a problem for Gulmohar.
After planting, fertilize the Gulmohar tree with a balanced liquid fertilizer for four to six weeks. Follow this two to three times a year for the upcoming three years. In early spring and winter, apply some more fertilizer. And every time you fertilize, remember to water the tree thoroughly.
Pruning is important for Gulmohar trees because that will facilitate a sturdy structure and allow them to fight heavy winds. Start pruning the main branches that are half the diameter of the trunk or less than 8 to 12 feet from the ground. The best time for pruning is late March or early April, or as soon as the spring season starts in your area.
Pests & Diseases
- Mostly, Gulmohar is devoid of pests, but some caterpillar species may eat the foliage.
- Spider mites can also be a problem, especially if the tree is not in a wet area. Increase the humidity or move the plant outside if you find spider mites.
- If scale bugs become a problem, take cotton swabs dipped in alcohol to treat them.
Gulmohar grows best under tropical conditions. So, in India, thorough winter care is not required unless you live in an area where the temperature drops below zero degrees Celsius. In that case, remember that frost is intolerable to the Gulmohar tree since it will rot the roots. So, cover smaller trees with burlap or a tarp overnight if there is ever a threat of frost.
A Gulmohar tree can grow as high as 40 feet and as wide as between 40 and 70 feet. If the right space is not provided, this tree may cause harm to other vegetation in your garden. So, keep the Gulmohar away from any paved surfaces, walls, or other objects that it might trample.
