Benefits of growing flowers yourself

Cost-effectiveness
Growing flowers from seeds is often more cost-effective than purchasing established plants or cut flowers. A packet of seeds typically contains numerous seeds, providing plenty of plants at a lower cost per plant.

Wide variety of choices
Sowing your own flowers allows you to choose from a vast variety of flower species and cultivars. You have the flexibility to select plants that suit your preferences, garden style, and local climate.

Customization
You have control over the entire growing process, enabling you to customize your garden according to your color preferences, fragrance choices, and design ideas.

Educational experience
Sowing flowers from seeds provides an educational experience. You can learn about the life cycle of plants, germination, seedling care, and the overall growth process. It’s an excellent hands-on learning opportunity for both adults and children.

Extended bloom period
By planting a variety of flowers that bloom at different times, you can create a garden with continuous or sequential blooms throughout the growing season. This contributes to a more visually appealing and dynamic garden.

Greater control over quality
You have control over the quality of the soil, compost, and fertilizers used during the growing process. This can positively impact the health and vitality of your flowers.

Sustainability
Growing flowers from seeds is often more environmentally friendly. It reduces the need for transportation associated with purchasing mature plants, and you can avoid the use of plastic pots commonly used in nursery-grown plants.
