Growing Mexican Sunflower Plant

Mexican sunflower plants are beautiful and easy to grow. They have bright orange and yellow flowers that can add a splash of color to any garden. The plant is also drought tolerant and can tolerate a variety of soil types. It is a great choice for beginner gardeners looking for an easy-to-care-for plant.

To get started, choose a spot in your garden that gets at least six hours of sunlight each day. The plant does best in full sun, but will tolerate some shade. Then make sure the soil is well drained and amended with organic matter such as compost or rotted manure.

Once the soil is prepared, it’s time to plant the seeds or seedlings. If you are planting seeds, do so in early spring when the temperatures are warm enough for them to germinate. Plant them about ½ inch deep and cover lightly with soil. Keep the soil consistently moist until the seeds germinate and begin to sprout, which should take about two weeks.

If you are planting seedlings, wait until late spring when all danger of frost has passed before transplanting them into your garden bed. Dig a hole twice as wide as the root ball of the seedling and just as deep – this will give the roots plenty of room to spread out without becoming crowded or root bound. Once planted, water well to help establish a good root system.

Mexican sunflower plants require very little maintenance once established. Just keep an eye out for pests such as aphids or caterpillars that may try to feed on its leaves or flowers, and use an organic insecticide if necessary to keep them in check. You should also deadhead any spent blooms throughout the growing season in order to encourage more blooms and prevent self-seeding from occurring unwantedly around your garden bed.

Light Requirements

Mexican Sunflower plants thrive in full sun and require at least six hours of direct sunlight each day. If planted in a partially shaded area, the plant may become leggy and sparse with fewer flowers.

Water Requirements

Mexican Sunflower plants prefer moist soil, but they can tolerate some dryness. It is recommended that the soil be kept evenly moist, but not soggy. Water the Mexican Sunflower plant in the morning so that any excess water can evaporate before nightfall. Make sure to avoid overhead watering as this can lead to fungal diseases such as powdery mildew.

Fertilizer Requirements

Mexican Sunflower plants do not require any fertilizer to thrive, but they will benefit from a light application of a balanced fertilizer in early spring or summer. Avoid using too much fertilizer as this can burn the roots of the plant and cause damage.
