CARE GUIDE

How to keep Jacobaea Erratica.

Light

Tansy ragwort comes from sunny, open habitats and grows best in full sun. It can tolerate partial sunlight but favors direct sun for optimal growth. This plant, which may be annual or biennial, is noted for its sun-loving character.

Water

Water ragwort flourishes in consistently moist environments and benefits from weekly watering to prevent drought stress. Although it has a moderate tolerance for dry conditions, it thrives best in damp soil that isn't waterlogged. In its native habitats, it relies on natural rainfall to promote growth and achieve lush foliage.

Temperature

Tansy ragwort can tolerate a wide range of temperatures, though its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer climates with adequate rainfall or watering. Extended periods of cloudy, rainy weather, as well as prolonged high temperatures, can increase the likelihood of Tansy ragwort dying. In winter, proper protection from cold can improve the plant's survival rate.

Fertilizer

Tansy ragwort requires regular fertilization to encourage flowering but does not tolerate excessive amounts. It needs small, frequent applications of fertilizer throughout its life cycle, especially during the peak of active growth and while it is flowering. You will feed your Tansy ragwort until it stops blooming.

Pruning

Water ragwort, with its vibrant yellow flowers, thrives in damp habitats. To maintain its health, it is best to prune it between early and late spring. This involves removing dead stems and improving air circulation around the plant. Pruning in this way encourages vigorous flowering and helps prevent legginess. Make sure to use clean tools to ensure the plant remains healthy.
