Gardening Advice

Cultivation Guide

Torenia grows well in partial shade, making it suitable for areas with less direct sunlight. However, for better blooming, it thrives in bright, indirect light or partial shade. Watering should be done when the top layer of the soil is dry, ensuring the plant receives enough moisture. During the hot summer months, especially in potted plants, it is important to prevent the soil from drying out.

Pruning the tips of the branches (pinching) encourages branching, leading to more flowers. Regular fertilization during the growing season will also promote healthy growth and abundant blooms.

Environment and Growing Conditions

Torenia prefers well-drained soil. Mixing some perlite into commercial potting mix can help create an ideal growing environment. It also does well in humid conditions, making it suitable for the hot and humid summers of Japan.

Torenia is generally grown as an annual since it does not tolerate frost. When the plant starts to wither in the fall, simply cut it back and prepare for planting the following year.

Conclusion

Torenia is an excellent choice for summer gardening due to its heat tolerance and ability to thrive in shaded areas. Its charming flowers and long blooming period make it a perfect addition to any garden or balcony.

Easy to grow and maintain, it is also a great choice for beginners. Try growing Torenia to enjoy its vibrant summer colors in your own space.
