What Is the Ideal Temperature Range for Stinking chamomile?

Ideal Temperature: 50 ~ 75℉

The ideal temperature range for Anthemis cotula, commonly known as stinking chamomile, is between 50°F and 75°F. In this range, the plant thrives best and exhibits optimal growth. Maintaining these temperatures ensures that the plant has suitable conditions for photosynthesis and nutrient uptake.

What Soil is Best for Stinking chamomile?

Soil type: Sandy soil, Loam, Sandy loam

Soil PH: 6.5 ~ 7.5

Anthemis cotula thrives in well-drained soil, which prevents water from pooling around the roots and causing root rot. This type of soil ensures the plant receives adequate water while avoiding waterlogging, promoting healthy growth and flowering. Although Anthemis cotula isn't very demanding, nutrient-rich soil can significantly enhance its growth. Such soil provides necessary minerals and nutrients, leading to vibrant foliage and an abundance of flowers. Soil with moderate moisture retention holds enough water to sustain the plant without allowing the roots to sit in water. This balance is crucial for Anthemis cotula to maintain its vigor and resilience against drought conditions.

How to Fertilize Stinking chamomile?

Fertilizer type: Balanced

For Anthemis cotula, it's crucial to apply fertilizer judiciously. A general rule is to use a balanced diluted liquid fertilizer at a quarter strength. For solid fertilizers, a light application every season suffices, ensuring not to overwhelm the plant's nutrient needs.

How to Prune Stinking chamomile?

Pruning Time: Spring, Summer

Begin by inspecting the plant to identify any dead or damaged stems. These can hinder the plant's overall health and should be removed first. Cut back to where the stem still appears healthy, ensuring a clean, angled cut. Once you've removed compromised parts, focus on shaping the plant. Trim back the tips of the stems to encourage bushier growth and more blooms. Pay special attention to any overcrowded areas to ensure light and air can circulate freely.

How to Propagate Stinking chamomile plant?

Propagate Time: Spring, Early spring

Begin by filling the seed trays with moist potting soil. Scatter Anthemis cotula seeds evenly across the soil surface and lightly press them into the soil. Do not cover them too deeply as they need light to germinate.

Use a misting spray or a gentle watering can to moisten the soil. The soil should remain consistently moist but not waterlogged. Overwatering may lead to root rot, hindering seedling growth.

Place the seed tray in a location receiving indirect sunlight. Direct sunlight can be too intense for seedlings. Alternatively, a fluorescent grow light can be used to provide necessary light conditions.

How to Repot Stinking chamomile plant?

Repotting frequency: Once every two years

Repotting Anthemis cotula should be done when you notice roots protruding from the drainage holes or the plant becoming root-bound. Additionally, if the soil seems compacted or the plant exhibits stunted growth, it might be time to consider repotting. Ideally, these conditions are most commonly observed in the Spring or Autumn, making these seasons perfect for repotting.

Choose a pot that is one size larger than the current one to accommodate growth and provide ample drainage. Ensure the pot has drainage holes to prevent waterlogging. A terracotta pot is an excellent choice as it allows for better moisture retention and air circulation, beneficial for Anthemis cotula's root health.

Opt for a well-drained loamy mix enriched with organic matter. This kind of soil enhances nutrient retention and provides adequate aeration, crucial for supporting healthy root development. Avoid heavy or overly clay-like soil as it can retain excess moisture, leading to root rot.
