Growth Conditions for Conyza pinifolia Lam.
Conyza pinifolia Lam. is a herbaceous, annual or biennial plant that thrives in a variety of environments. It is a member of the Asteraceae family, commonly referred to as the daisy family, and is commonly known as Pineleaf Horseweed or Pineywoods Fleabane. It is found both in the native and cultivated landscapes, often considered a weed in agricultural settings, and is native to North America.
Light Requirements
Conyza pinifolia prefers full sun or partial shade. It will grow in shaded conditions but will have a spindly growth habit with diminished flowering. In full sun, the plant will have a robust growth habit with a greater number of flowers. The amount of light influences the growth habit of the plant.

Cold snaps, particularly in the flowering phase, can kill the plant. The optimum temperature range for growth and development is between 20°C and 25°C.
Soil Requirements
Conyza pinifolia grows well in a range of soils from sandy loam to heavy clay soils. The preferred pH range is neutral to slightly alkaline (pH 7.0 to 7.5). The plant is not salt tolerant and does not perform well in saline conditions. Moist and well-drained soils with moderate to high fertility are preferred for optimal growth and development.
Cultivation methods for Conyza pinifolia Lam.
Conyza pinifolia Lam. is a plant that can be grown indoors or outdoors. It is mostly drought tolerant and can survive in different types of soils, but it thrives best in well-drained soils.
The seeds should be planted in spring or fall. It is important to prepare the planting site by removing weeds and rocks. With the aid of a rake, loosen the soil to a depth of about 4 inches before planting.
A spacing of about 6-12 inches should be kept between each plant. The seeds should be planted at a depth of about 1/8 inch. After planting, the soil should be moistened without creating waterlogged conditions.
Watering needs of Conyza pinifolia Lam.
Conyza pinifolia Lam. prefers moderate watering. It is important that the soil is moist but never soaked with water. During dry seasons, the plant should be watered regularly to ensure it doesn’t wilt, and the soil should be allowed to dry between watering intervals.
During the winter season or periods with low sunlight, watering should be reduced to prevent waterlogging and encourage the plant to go dormant.
Fertilization of Conyza pinifolia Lam.
Conyza pinifolia Lam. requires a well-balanced fertilizer that is rich in nutrients. The best time to fertilize is in the early spring before the growing season begins.
Organic fertilizers such as compost and bone meal can be used to provide the necessary nutrients needed for growth. Synthetic fertilizers can also be used, but it is important to follow the manufacturer's instructions carefully so as not to over-fertilize the plant, leading to root burn.
Pruning of Conyza pinifolia Lam.
Pruning is necessary for Conyza pinifolia Lam. to promote bushy growth and remove dead or damaged leaves and branches. It is best to prune the plant in late winter or early spring before the growing season begins.
When pruning, it is important to make clean cuts using a sharp and sterilized pruning shear to prevent infections. Also, only cut 1/3 of the plant per pruning session to prevent stressing the plant.
Propagation of Conyza pinifolia Lam.
Conyza pinifolia Lam. can be propagated through both seed and vegetative methods.
Propagation through Seeds
The seeds of Conyza pinifolia Lam. can be sown directly into the soil. It is ideal to sow the seeds at the start of spring when the temperature starts to rise, and the days get longer. The seeds should be sown in a well-draining soil mix, ensuring that the soil is moist but not waterlogged. The seeds should be sown at a depth that is roughly twice the size of the seed itself. The seedlings should emerge within a few weeks, and the plants should be thinned out once they have developed their second set of leaves.
Propagation through Cuttings
Conyza pinifolia Lam. can also be propagated through stem cuttings. This method is useful when one wants to maintain the characteristics of a specific plant. The cuttings should be taken from healthy plants, preferably during the growing season. The cuttings should be taken from mature stems about 10 cm long, and any leaves should be removed from the bottom half of the stem. The cuttings should then be planted into a well-draining soil mix, with the bottom half of the stem buried in the soil. Ensure that the soil is moist and that the cutting has plenty of indirect light.
Overall, Conyza pinifolia Lam. is a relatively easy plant to propagate and grow. Through the use of either seed or vegetative methods, one can successfully propagate this plant with minimal effort.
