Every plant has its lifespan. While some plants live for a short while, like one year, others may have a life span as long as two years and even more.
Undoubtedly, how far a plant will grow and live to complete its life cycle can depend on how careful you are in treating it. For example, Rosemary is a perennial plant, that has a long life span.
So, does Rosemary come back every year? As a perennial, Rosemary can come back every year until the plant is spent. With proper care, climate, and soil, Rosemary will only briefly suspend growth during winter to pick up again after the frost. Even at the end of its lifespan, Rosemary will reseed in winter to start new plants in better conditions.
Does Rosemary Come Back Yearly?
Rosemary does come back yearly. Like every other perennial plant, when Rosemary is planted in fertile soil, watered nicely, and gets adequate sunlight, it will come back the following year.
When the right conditions are available for plants, they grow well and produce better.
Some soil conditions that will make a rosemary plant come back the following year include the following:
1. Soil pH:
Rosemary grows well in slightly acidic soil with a pH range from 6.0 and 7.0. pH affects the absorption of nutrients by plants.
Alkalinity will cause stunted growth. When the growth of Rosemary is stunted, it may die off and fail to come back another year.
However, when the soil pH is within the earlier mentioned range, Rosemary will grow back.

2. Drainage system:
Drainage in the soil helps remove excess water. Excess water will cause edema, which affects the absorption of nutrients in a plant, and the result afterward is death.
With well-drained soil, Rosemary will thrive, and the roots will absorb nutrients properly, which will cause the plant to thrive and continue to live since dormant parts have enough to live on.
When the drainage is not reduced or stopped, Rosemary has the possibility of coming back the following year.
3. Type of soil:
Many varieties of Rosemary grow well in loamy soil; loamy soil is known for its rich nutrients. When Rosemary is grown on loamy soil, the nutrients in the soil are trapped in the plant.
This soil will help the plant stay longer and start another cycle without dying off. But, if you are living where you have clay soil then I would recommend you to read this article.
4. Water availability:
Water is essential for every plant to grow. When soil is watered correctly, the soil is richly moisturized, and plants grow better.
For example, when Rosemary is adequately watered, the water aids nutrient absorption, hence a speed growth or regrowth.
Nonetheless, too much water will cause a lack of nutrient absorption, edema, dampening, and rotting of leaves, roots, and stems.
The soil should not be too dried or too moisturized but balanced to help Rosemary grow. With the right amount of water, Rosemary will continue to live on, coming back yearly.
Will Rosemary Plant Come Back After Winter?
Rosemary will come back after winter, but this depends on how you treat the plant during that time of the year.
Rosemary survives well with temperatures ranging below 10 – 20°F (-7 to – 12C).
However, for Rosemary to survive in winter, it is dependent on the zone it is planted.
Zones that do not go below the earlier mentioned temperatures will leave Rosemary dormant enough to come back after winter.
Some activities that will help Rosemary come back after winter are:
1, Snipping off damaged leaves and stems after winter.
2, Improving soil drainage to avoid a very damp environment which may cause root rot.
Improving soil drainage creates room for the right amount of water to be absorbed by the plant and proper airflow.
In addition, proper air circulation prevents root rot which may cause death to the plant.
3, During the winter season, grow Rosemary in pots and large containers indoors, protecting the plant from frost.
When already planted directly to the ground before winter comes, you should provide shade for the plant to protect it from too much frost.
4, Deep Pruning: Pruning is required for plants to continue in the production of new leaves. During winter, deep pruning is required to keep Rosemary alive.
Pruning deep will help chop off the leaves and parts of the plants affected by frost and prevent the frost from spreading to other parts of the plant.

Does Rosemary Die In Winter?
Rosemary may die in winter when extreme cold from frost and when too much water is available.
Although Rosemary is an actual Mediterranean plant, it is affected by the very extreme cold in the winter season.
The death of Rosemary may occur in winter because of cold from frost and much available water during this period.
As mentioned in the previous subtopic, Rosemary’s survival in winter depends on specific activities you engage in during that time of the year.
Some of the following may happen to Rosemary in winter:
- Dampening: Water is essential for the survival of every plant, but too much water leads to dampening.
- Edema: Due to the presence of much water during the winter season, the water is accumulated in the roots, stems, and leaves, causing swelling.
- Rotting roots, leaves, and stems will become present, especially when there is poor drainage in the soil. When water is too much in plants, the roots, leaves, and stems become very soft, leading to rot.
Rosemary may grow continuously as a perennial in the tropics, but in temperate regions, outdoor Rosemary is forced to stop growing in winter.
Notwithstanding, Rosemary comes back every year after the frost and resumes growth speedily.
Â If it is going to bother moving your Rosemary indoors during winter, you can count on it to grow back after the frost.
This article has properly discussed all requirements to keep Rosemary alive during winter and enable regrowth afterward. Just be sure to apply the guidelines properly!
