The Four O’Clock flower, also known as Mirabilis jalapa, is a beautiful and fragrant plant that boasts trumpet-shaped flowers in an array of colors, including pink, yellow, red, and white. These stunning flowers open in the late afternoon and remain open until the following morning, hence their name. Growing Four O’Clock flowers is relatively simple and can add a touch of elegance and fragrance to any garden. In this article, we will guide you step-by-step on how to grow four O’Clock flowers successfully.

1. Choose the location: Four O’ Clock plants prefer full sunlight or partial shade with well-draining soil for optimal growth. Therefore, select an area in your garden that receives at least 6-8 hours of sunlight per day and has loose, fertile soil enriched with organic matter.

2. Planting the seeds: The best time to plant Four O’ Clock seeds is in late spring when the soil warms up and all risks of frost have passed. Sow the seeds 1/4 inch deep into the soil and space them about 12-18 inches apart to provide adequate room for growth.

3. Watering: Water the seeds evenly immediately after planting and continue to keep the soil consistently moist throughout their germination period (approximately two weeks). Once the seedlings have emerged, reduce watering frequency but ensure that a deep watering routine is maintained during the growing season.

4. Fertilizing: To promote vibrant blooms throughout the summer, apply a balanced fertilizer (10-10-10) every four weeks during the growing season. Be sure not to over-fertilize as excessive nutrients can lead to less flowering.

5. Pruning: While Four O’ Clock plants can grow quite large (up to 3-6 feet tall), it may be necessary to remove any dead or diseased branches. Pruning promotes airflow and encourages a bushy, healthy growth habit.

6. Pest and disease control: Four O’ Clock plants may attract pests such as spider mites or aphids. It is crucial to monitor the health of your plants regularly and treat pests as needed using insecticidal soap or other organic solutions. Additionally, they may suffer from diseases like leaf spot or powdery mildew which can be treated with fungicides.

7. Overwintering: In colder climates, where the temperature drops below freezing, Four O’ Clock tubers must be dug up in the fall and stored indoors until spring. Gently remove the tubers from the soil, allow them to dry for a few days, and store them in a cool, dark place – ideally between 45°F to 50°F (7-10°C). Replant them the following spring once the threat of frost has passed.

With these steps in mind, you are now well-equipped to grow Four O’Clock flowers in your garden successfully. Their vibrant colors and lovely fragrance will certainly make them a unique and charming addition to your garden landscape.
