How to Care For Rosemary Bonsai

Rosemary Bonsai is known not only for its beauty but also for its distinctive flavor and medicinal value; the rosemary herb is a perfect plant for your bonsai gardening. The rosemary is an attractive, tiny-leafed shrub that produces fragrant white, blue, or pink flowers during summer and spring. With the herb partially shedding its fibrous bark, the bonsai plant achieves a beautiful “old” look, even when the herb is still young. Easy to care for, the rosemary bonsai requires a proper location and attention to thrive well inside a house.

How to Care for the Rosemary Bonsai

Obtaining a rosemary bonsai is easy since one can purchase it from a nursery plant or collect one from nature (if you’re an explorative gardener). Bonsai gardeners know that the crucial task is caring for the rosemary bonsai. So, how do you care for the rosemary bonsai?

Positioning Your Rosemary Bonsai

The location of the rosemary bonsai in the house determines well how it will thrive. That said, positioning describes lighting and temperature conditions under which the plant is maintained. We recommend that you place your plant close to the patio door or close to the window. This will allow it to obtain optimal natural light and sun warmth, about six to eight hours each day. The rosemary plant thrives in warm and humid environments but still exhibits some winter-hardiness. Therefore, the plant can be grown in USDA Zone 7 areas successfully. However, temperatures below ten degrees Fahrenheit are lethal for the plant.

Watering Your Rosemary Bonsai

Water is essential for the growth of the rosemary bonsai. However, take caution in watering the rosemary plant. The rosemary plant does not like wet roots and can survive a day or two on dry soil. Since the rosemary plant is sensitive to overwatering, you should use soil that has good drainage. Using terra cotta pots for your rosemary bonsai can aid in avoiding overwatering with the pots allowing the soil to dry out quicker. We recommend that you water the rosemary bonsai when the soil is nearly dry. During the watering process, allow the rosemary plant to soak up water till the soil surface on top is damp.

Fertilizing Your Rosemary Bonsai

With small amounts of soil in the pot, the nutrient supply will run out as the rosemary plant grows. That explains why fertilizing is essential in achieving optimal health for your bonsai plants. After all, no one likes their plants weak and dull-looking. During the growth period of the rosemary bonsai, a weekly supply of supplemental fertilizer is crucial. After the rosemary bonsai has matured, fertilizing it twice yearly would serve the plant best. While fertilizing, you should use the fertilizers at half the recommended strength. The application of the fertilizer should be done by misting.

Training Your Rosemary Bonsai

If you’d like to add glamour to your rosemary bonsai, training is essential. In most cases, when mature rosemary bonsai are sold at tree nurseries, they are trained. The only requirement is periodic pinching and trimming of the plant to keep it miniature. To do this, remove all new growth beyond the plant’s first set of leaves. Eliminate the dead branches as well. With growth rates for different bonsai trees, the evaluation of one’s tree growth rate is vital for optimal trimming and pinching.

What Pests and Diseases Affect Rosemary Bonsai?

When it comes to indoor growing of the rosemary bonsai, gardeners should beware of powdery mildew. This refers to the white and powdery fungus that develops on the rosemary plant if the house had humid conditions and poor air circulation. While the fungus may not kill the bonsai, it makes it more susceptible to other diseases and attacks by insects. To avoid this, keep the house’s humidity low, with good air circulation. Aphids and spider mites are pests to look out for when caring for the bonsai. Treatment of your rosemary plant using non-toxic pesticide soap or any sulfur-based fungicide before the total infestation is essential in getting rid of the pests and fungi.

Unlike more complicated bonsai trees, the rosemary is quite easy to cultivate, even for beginners. While rosemary is viewed by many as a culinary item for seasoning, the plant is also a perfect choice for artistic purposes by bonsai gardeners. With several varieties to choose from, one can hardly get enough of the rosemary bonsai that come in abundant colors, shapes, and scents.
