Best Soil for Myrtle Plants

However, you should plant it in a loam-based compost with good ventilation and filtered light for best results. Look out for iron chlorosis that occurs in highly alkaline soil with a pH higher than 8.3. The plant does not do well in lime, and the leaves start to turn yellowish. In this case, lower the soil PH with the treatment of nitrogen fertilizer or elemental sulfur.

How Much Light Do Myrtle Plants Need?

The Myrtle plant thrives best in full to partial sun in a location sheltered from drying, cold wind. When grown indoors, it will require a lot of air and light. During the hot summer, set it in a semi-shade outdoors. In autumn and winter, place the plant in a cool room where temperatures are approximately 50 degrees Fahrenheit underneath grow lights. You should aim for about six hours of good, indirect sunlight every day.

How Often to Water Myrtle Plants

If possible, use rainwater for watering because myrtle tree doesn’t do well in high lime concentrations. If tap water is the only available option, fill it in a jug and leave it on the side several hours before watering. This will allow the water to warm up to room temperature and allow various chemicals such as chlorine to evaporate.

If you are located in cold regions, it is best to keep your myrtle tree indoors for most periods of the year. During the summer, when the weather is mild and warm, you can place the plant outdoors. However, ensure to keep the plant indoors if the temperature drops below 10 degrees Celsius.

On the other hand, dry air can negatively affect the general condition and flowering. You should hence maintain relative humidity during hot summer days by spraying water on the leaves.

Best Fertilizer for Myrtle Plants

Begin to fertilize your myrtle tree early when the growing season begins. Use water-soluble liquid fertilizer each week during the growing season and summer. Feed the last fertilizer in the autumn when the growth is slow. Do not fertilize the Myrtle plant in winter when there is minimal growth. If the winter location you place the plant is more than 10 degrees Celsius, it will continue to grow. Hence you should continue feeding it a little fertilizer twice a month.

How to Propagate Myrtle Plants

The Myrtle Plants can be propagated from stem cuttings and seeds. You will get the best results in summer and spring with semi-hardwood stem cuttings. Propagation is also possible with air-layering.

Growth Rate of Myrtle Plants

The myrtle plants have a moderate growth rate. Depending on the conditions and variety of the Myrtle plant, this long-lived perennial tree can grow up to 16 feet tall within ten to twenty years.

Ideal Pot Size for Myrtle Plants

The ideal pot size for the Myrtle plant is one that gives the roots sufficient room to grow. A pot at least 30 cm wide or bigger will be good to go. You should report the plant to a bigger pot after 2 to 3 years, which will also help replenish the soil nutrients.

Repotting Tips for Myrtle Plants

You should report young myrtles after every two to three years or when the tree outgrows its current pot, and the matured older plants every three to five years to replenish the soil and maintain a healthy tree.

When selecting the next pot, you should consider a 2-3 inches larger size than the current pot. Also, ensure the new pot has good drainage with holes in the bottom and report using lime-free, free-draining compost.
