How to Grow Eucalyptus from Seed?
Eucalyptus, an Australian natural tree that comes in over 500 varieties and can reach heights of 150 feet, is a plant that resembles a tree when grown in a greenhouse. Additionally, it grows in the United States’ warm states of Texas and California.
If it doesn’t get below 10 °F, it can grow everywhere. Even though any species of eucalyptus can be produced from seed, only hardy varieties that have already established themselves in the UK are worth considering for propagation.
In the right circumstances, particularly between mid-spring and mid-summer, growing eucalyptus can be faster than growing other trees. Choose seeds from parent plants that thrive in environments susceptible to frosts comparable to or more severe than those expected to occur at the desired planting site. In four to twenty days, eucalyptus seeds can begin to grow.
Many species of eucalyptus are characterized by silvery leaves with a strong aroma, which is why they are frequently used in floral arrangements. In addition, it produces beautifully dried or cut flowers for arrangements thanks to its eye-catching round or oval aromatic leaves.

How to Grow Eucalyptus from Seed?
It is concerning since eucalyptus do not as their roots disturbed. Most of the time, seeds are placed in starting trays and moved up as they grow. When you do locate seeds, it is not advisable to distribute them directly into the garden because a transplant takes around 10 to 12 weeks to develop.
The seed must be transplanted outside after beginning to grow indoors. The seeds should be exposed to plenty of sunlight as soon as they germinate.
The trees grow quickly to 8 feet and are frequently planted in the spring. One can grow a eucalyptus tree indoors in a pot. It will, however, grow to a size that is impossible to contain.
You should carefully weigh your alternatives because eucalyptus trees might be challenging to plant. If you don’t have enough place for the idea, you might want to give up on it. Here are some suggestions for how to grow eucalyptus from seed if you are one of those folks with extensive gardens:
- In an indoor starter tray, eucalyptus seed should be sowed. Then, before the last frost, sow seeds in cell trays or open flats 10–12 weeks prior. On top of a carefully sieved compost, the seeds need to be put in deep pots measuring 7-9 cm in depth in February.
- Instead of burying the seeds, press them into the compost before covering them with a thin layer of lime-free horticultural grit. Sift sand over the flower seed after firmly planting it on the earth. To keep the seeds damp, water them from the bottom up. When the seedling reaches a height of 4 to 5 inches, transplant it into a container.
- Before covering the pots with a clear piece of glass or Perspex, gently moisten the seeds into the soil without disturbing them.
- Maintain the soil at a temperature between 13 and 16 degrees Celsius above the required 4 degrees of air temperature if soil warming is possible.
- In a few weeks, most eucalyptus seeds will begin to sprout. Plants planted on open flats should be transferred to cell packs or 3-4″ pots as soon as the first genuine leaves appear. Once seedlings begin to appear, remove the covers, and soil heaters, then move the plants to an area with full light.
- Once the seedlings’ roots have taken hold, they can be moved outside to a cold frame. Again, keep the lights on unless there is a likelihood of extremely heavy or persistent rain. Once they reach 30 cm in height, the seedlings can be planted inside or outside in their final position.
- Decide on a sunny location. Eucalyptus requires full sun, which requires at least 6 to 8 hours of daily direct sunshine. After confirming that there is no longer any danger of frost in your location, plant outside.
- The base of the cane should be placed 2-3 cm apart from the stem to prevent harm to the root system.
- Although eucalypti can tolerate brief droughts, they thrive in consistently moist soil. In cases of prolonged dryness, water the trees once each week. A plant not getting enough water will show signs of dehydration by having its leaves shrink.
- Frequent fertilization of the plant is necessary during the growing seasons. Add a liquid fertilizer to the water before watering the plant once a week.
Is Eucalyptus Easy to Grow from Seed?
By propagating from seeds, eucalyptus trees can be grown robustly for ornamental purposes in the most common and straightforward approach. However, rooting cuttings are a little more complicated if no micropropagation facilities or mist propagation tools are available. In addition, finding rooted cuttings might be challenging.
If you are used to finding these trees in parks or woodlands, you might be surprised to learn that you can grow them indoors. Like every cut flower, eucalyptus needs moisture, heat, and sunshine to grow. In actuality, there aren’t many things that make it especially tough in a chilly climate with a short growing season. It takes time to ripen and flourish.
As was previously mentioned, eucalyptus plants are quite simple to grow quickly. However, they can be finicky. The best choice is to go with a species that does well indoors and is smaller. With some caution, they can be transported inside as houseplants. Potted eucalyptus trees may provide beauty and scent to your patio.
How Fast Can Eucalyptus Seeds Start to Germinate?
Eucalyptus grows incredibly fast. This tree can grow up to two feet every year or more. Eucalyptus requires 14–21 days of germination time at 65–75°F. Lightly covering the seeds will keep them warm and moist up until germination. Once the seeds have emerged from the bottom heat, remove any humidity dome, and take them outside.
One of the reasons it is a green choice is the quick growth of the trees. Many kinds are already mature ten years after planting. Comparatively speaking, other hardwoods, which can take 18 to 25 years to reach early maturity, mature in a fraction of that time. As a result, USDA plant hardiness zones 8 to 11 are where it grows most successfully.
Where Does Eucalyptus Grow Best?
Eucalyptus trees and bushes, which have a rapid growth rate, are native to Australia, Malaysia, and the Philippines and can be found in various soil conditions and temperatures.
In the United States, you can find them in Hawaii’s frost-free areas, the southernmost parts of California, Texas, and Florida, as well as zones 10 and higher. In addition, they may survive in a wide range of soil types, from hot, dry areas to relatively humid ones, as long as the area has sufficient drainage.
Eucalyptus trees have a long history in locations like California, Hawaii, and Arizona, where early settlers planted the trees for windbreaks, shade, and hardwood lumber, despite being a severe fire risk and an invasive species in some parts of the country.
Most plants may be grown easily in the warm USDA hardiness zones 8 through 10. Plant on well-drained soil in a sunny spot and partially shielded from chilly, drying breezes. No staking is necessary for the young plant. Roots will grow more robustly in plants that are allowed to develop naturally.
These species range in size from small, shrubby plants that do well in pots to ones that can grow to 400 feet or more. Their skin feels good to the touch, and their bark is easily pulled off.
Even though all eucalyptus trees require full light, certain species can survive in conditions where they are partially shaded.
Can Eucalyptus Grow in Pots?
They are tall trees with evergreen foliage that are fragrant. The tree, however, also grows well inside. Therefore, up until the point at which they must be planted outside or given to a park, eucalyptus trees in containers can be grown as container perennials.
Because the seeds are released as the pods ripen, gather the pods as soon as they start to turn brown. You may get rid of the seeds by splitting the pods open along the seam. For the duration of the winter in too-cold areas, eucalyptus can be potted and kept indoors.
Eucalyptus can be cultivated in containers. A great plant to grow in a pot is the eucalyptus. Dwarf fir, cypress, hemlock, spruce, juniper, and pine can stay in the same pot for up to five years because they require very little upkeep, come in a wide range of hues, shapes, and textures, and grow slowly.
Either inside or on a sunny patio, if there is enough light. Because they would grow more slowly than those planted in the ground, specimens grown in containers must be constantly clipped to a manageable size.
To encourage the shrub to grow harmoniously, you might keep the planting stake in place for the first year. Then, ensure that the potting soil is completely moist by watering until water begins to leak from the drainage holes at the bottom of the pot.
Let the potted eucalyptus dry out a little bit in between waterings. Garden soil that has been composted to make it more fertile should be placed on top of a layer of clay balls in the container’s bottom.
Final Verdict
The eucalyptus is a beautiful tree with blue-grey leaves and a strong perfume that people associate with the Mediterranean. Eucalyptus is not challenging to grow from seed, but it does require persistence and thought. You might be able to grow a magnificent houseplant or addition to your yard with a bit of tender care. It has the potential to grow into either a single plant or stunning hedges.
Because of its enormous size and exotic appearance, eucalyptus is generally employed as an aesthetic tree in gardens, but it also has several other uses. For example, certain tree kinds can be cultivated in pots or tubs.
Urban regions can install it, and it has excellent pollution resistance. Additionally, it can be planted to produce eucalyptus syrup for your beverages, dried branches can be used for crafts, and they can be used as a cold treatment.
