This article provides an introduction to why rosemary cannot be grown at home, as well as discussing the benefits and drawbacks of this aromatic plant. Details are as follows:
Rosemary potted plants always wither and turn black, add this to the soil for vigorous growth and a more fragrant taste
With a refreshing aroma, it can be used in cooking, as well as for repelling insects. It can be made into insect repellents and fragrance bags, and essential oils can also be extracted. This "versatile" plant is called rosemary, which blooms small blue flowers in summer and is also known as "sea dew."
Many people encounter the problem of withered and blackened leaves when growing rosemary. One of the key issues is ventilation, especially in the summer, where high temperatures and humidity can cause the plant to easily die if ventilation is poor.
Rosemary must be placed in a well-ventilated area and prefers a sunny environment, requiring at least 6-8 hours of sunlight each day (partial shading in summer). Therefore, rosemary is not suitable for indoor cultivation.
Why can't rosemary be grown at home?
Rosemary has lush branches and leaves, and dense foliage can affect ventilation, so it should be pruned regularly. Light pruning is sufficient; heavy pruning can cause the plant to struggle to grow new leaves on old branches. The pruned branches and leaves can be used for cooking or steeped in water. You can also create a 'candy cane' shape, which not only enhances ventilation but also looks aesthetically pleasing.
Some gardening enthusiasts say, "I have good ventilation and no issues with care, but why won't my rosemary grow well?" It's possible you've overlooked a detail--the soil.
One difference between rosemary and other plants is that it prefers slightly alkaline soil. The soil used for growing roses, including the general-purpose nutrient soil available on the market, is slightly acidic, which is not comfortable for rosemary. You can add some alkaline granules to the soil, such as perlite or rice husk charcoal.
If not available, you can also add desiccants to the soil, which are the small packs found in snacks like cookies. One small pack mixed into a gallon of soil is sufficient.
