Description of Tanacetum Vulgare
Tanacetum vulgare, commonly known as tansy, is a flowering herb that belongs to the Asteraceae family. The plant is native to Europe and Asia, but it has been introduced to other parts of the world, including North America and Australia.
General Appearance
Tansy is a perennial plant that typically grows up to 1-1.5 meters in height. The plant has a smooth, upright stem that is green or reddish-brown in color. The leaves are fern-like and deeply divided, with toothed edges. The flowers are yellow and button-like, growing in clusters at the top of the stem.
Common Uses
Tansy has been used for various medicinal purposes throughout history. The herb has been used to treat digestive issues, menstrual cramps, and rheumatism. It is also used as a natural insect repellent. Apart from its medicinal properties, tansy has also been used in traditional cooking as a flavoring agent for dishes such as cakes and puddings.
However, it is important to note that tansy is toxic when consumed in large amounts, and the plant can cause skin irritation in some individuals. Therefore, it is advised to use caution when consuming or handling the plant.
Alternative Names
Apart from tansy, Tanacetum vulgare is also commonly known as common tansy, golden buttons, and bitter buttons.
Light Requirements
Tanacetum vulgare, also known as common tansy, is a plant that requires full sun exposure to thrive. It can tolerate some light shade, but it will not grow as vigorously or bloom as profusely in these conditions.
Temperature Requirements
Common tansy is a hardy plant that can tolerate a wide range of temperatures. It can grow in USDA hardiness zones 4 through 9, meaning it can tolerate minimum temperatures of -30 to 30 degrees Fahrenheit (-34 to -1 degrees Celsius).
While common tansy can handle some heat and drought, it will not grow well in hot, humid temperatures. Ideal growing temperatures for this plant are between 60 and 75 degrees Fahrenheit (15 to 24 degrees Celsius).
Soil Requirements
Common tansy can grow in a variety of soil types but prefers well-draining and moderately fertile soil. It can tolerate slightly acidic to slightly alkaline soil pH, ranging from 6.0 to 7.5.
It is important to note that common tansy can grow aggressively and become invasive in ideal conditions. It is recommended to plant it in a confined space or container to prevent it from spreading too rapidly.
Cultivation Methods
The Tanacetum vulgare plant is generally grown as a herbaceous perennial for its ornamental value and medicinal properties. It is best cultivated in full sunlight to partial shade, in well-drained soil that has a pH range of 6.5 to 7.5. Ensure that the soil is rich in organic matter. Sow the seeds indoors during the spring season and transplant the seedlings when they are large enough to handle. Plant the seedlings at a distance of 60-75cm apart.
Watering Needs
Tanacetum vulgare should be watered only when the soil around it is dry since they have relatively low water requirements. Avoid overwatering, as it may lead to root rot, fungal and bacterial diseases. Mulching the soil around the plant helps to retain moisture in the soil, aids in water conservation and helps to regulate soil temperature.
Fertilization
Tanacetum vulgare does not require a lot of fertilizer. Apply compost, or well-rotted manure early in spring to provide the necessary nutrients to the plant. Some granular slow-release fertilizer can also be used at the same time. Excess nitrogen results in excessive foliage growth, reducing the plant's sesquiterpene lactone concentration. Therefore, avoid applying too much nitrogen fertilizer.
Pruning
Regular pruning helps to maintain the desired shape and size of the Tanacetum vulgare plant. Pinch back the plant's tips in the early stages to stimulate bushier growth. Deadheading, or removing the plant's faded flowers, encourages the plant to continue flowering throughout the growing season. Cut back the plant's foliage just before it blooms in summer to force the plant to bush outwards, producing more flowers.
Propagation of Tanacetum vulgare
Tanacetum vulgare, commonly known as tansy, is a perennial plant that belongs to the aster family. Propagation of tansy can be done through various methods including:
Seed propagation
The easiest and most common method of propagation of tansy is through its seeds. The best time to plant tansy seeds is in the spring or fall. Sow the seeds on the soil surface and cover them with a thin layer of soil. Keep the soil moist until the seeds germinate. Once the seedlings have grown true leaves, you can transplant them in your desired location.
Division
Division is another method of propagating tansy, especially if you have an established plant. Dig up the plant early in the spring or fall, divide it into sections, and replant each section separately. Ensure that each section has enough roots and shoots to grow independently.
Cuttings
Another way of propagating tansy is through stem cuttings. Take cuttings from the plant's stems during the active growing season, ensuring that each cutting has at least two leaves. Remove the lower leaves and dip the cuttings' base in rooting hormone. Place the cuttings in moist soil and cover them with plastic to keep them moist. Once the cuttings have rooted and grown enough foliage, you can transplant them outdoors.
Propagation of Tanacetum vulgare is relatively easy and straightforward, making it an excellent choice for beginner gardeners.
Disease and Pest Management for Tanacetum vulgare
Tanacetum vulgare, also known as tansy, is a hardy perennial plant that is relatively easy to grow. However, like all plants, it is susceptible to a range of diseases and pests. Here are some of the most common issues that can affect tansy, and how to manage them:
Diseases
Powdery Mildew: This fungal disease appears as a white or gray powdery coating on the leaves and stems of the plant. It can weaken the plant and make it more susceptible to other diseases. To manage powdery mildew, remove infected leaves and treat the plant with a fungicide.
Leaf Spot: This fungal disease appears as brown or black spots on the leaves of the plant. It can cause the leaves to yellow and fall off, and can weaken the plant over time. To manage leaf spot, remove infected leaves and treat the plant with a fungicide.
Root Rot: This fungal disease attacks the roots of the plant and can cause wilting and death of the plant. To manage root rot, ensure that the soil is well-drained and avoid over-watering the plant. If the plant is infected, remove it from the soil and dispose of it (do not compost).
Pests
Aphids: These small, pear-shaped insects suck the sap from the plant and can cause stunted growth and yellowing of leaves. To manage aphids, spray the plant with a jet of water to remove them, or treat the plant with an insecticide.
Leaf Miners: These small, fly larvae tunnel through the leaves of the plant, causing brown patches and holes. To manage leaf miners, remove infected leaves and treat the plant with an insecticide.
Spider Mites: These tiny, spider-like insects also suck the sap from the plant, causing yellow leaves and stunted growth. They also produce fine webbing on the plant. To manage spider mites, spray the plant with a jet of water to remove them, or treat the plant with an insecticide.
With good management practices and prompt action, you can keep your Tanacetum vulgare plants healthy and productive for years to come.
