Planting Instructions
Seed Sowing and Care
Want to grow beautiful 4 O’Clock flowers? Start by sowing seeds outdoors in spring after the last frost. For indoor planting, begin 4 to 6 weeks prior. Make sure to plant seeds about 1/4 inch deep and space them 1 inch apart. This method allows for optimal growth.
Seeds typically germinate within 5 to 10 days, making it a quick process. Once seedlings reach about 2.5 cm, thin them out to ensure healthy development. This step is crucial to prevent overcrowding, which can hinder growth.
If you’re in a cooler climate, consider starting seeds inside. It gives them a head start, allowing for vibrant blooms later. Don’t forget to label your plants! A set of Plant Labels and Markers can help you keep track of your seedlings and their progress!

Tubers vs. Seeds
When deciding between tubers and seeds, both methods have their perks. Seeds are cost-effective and easy to find, while tubers can yield stronger, more established plants. Many gardeners prefer tubers for quicker blooms and enhanced vigor.
However, tubers require proper storage over winter. Keep them in a cool, dry place to ensure they remain viable for the next planting season. This can save you money in the long run.
Some gardeners enjoy the thrill of growing from seeds, while others swear by tubers. Why not try both? You might discover which method works best for you. Share your results and experiences with us!

Growth and Care
Watering and Feeding
Watering 4 O’Clock flowers is essential for their health. These plants prefer consistent moisture but can tolerate some drying. Water them deeply about once a week. If your area experiences drought, check the soil moisture. Under-watering will cause wilting, while over-watering can lead to root rot. Signs of over-watering include yellowing leaves and a mushy root system.
When it comes to fertilizing, both organic and synthetic options are available. Organic fertilizers, like compost or well-rotted manure, provide nutrients gradually. Synthetic fertilizers can offer a quick nutrient boost. Apply fertilizer every 4-6 weeks during the growing season for optimal growth.
By following these watering and feeding tips, you can set your 4 O’Clocks up for success. For even more effective growth, consider investing in High-Quality Potting Soil. It ensures your plants get the best nutrients right from the start!
