Designing a planting plan for a spring garden with the given specifications can create a vibrant and sustainable garden space. Here’s a suggestion that balances perennial and annual plants suitable for subtropical climates, ensuring continuous flowering from March to October.

Garden Layout:

• Size: 3 meters by 5 meters (15 square meters)
• Climate Zone: Subtropical
• Plant Distribution: 60% Perennials (9 square meters) and 40% Annuals (6 square meters)

Perennial Plants (60% of Garden):

Perennials provide the backbone of the garden, offering structure and continuity across seasons. Select perennials that are well-suited to subtropical climates, ensuring they can thrive with minimal winter chill.

1. Lavender (Lavandula spp.) – Drought-tolerant, attracts pollinators, and blooms in late spring to summer.
2. Salvia (Salvia spp.) – Offers a range of colors and blooms from spring to fall.
3. Gardenia (Gardenia jasminoides) – Fragrant white flowers that bloom in late spring to early summer.
4. Hibiscus (Hibiscus spp.) – Large, colorful flowers that bloom throughout the summer.
5. Bird of Paradise (Strelitzia reginae) – Exotic flowers that can bloom multiple times a year.

Annual Plants (40% of Garden):

Annuals will provide vibrant color and can be changed each year to refresh the garden’s appearance.

1. Marigolds (Tagetes spp.) – Bright, cheerful flowers that bloom from spring until frost.
2. Petunias (Petunia spp.) – Wide range of colors, blooming from spring to fall.
3. Zinnias (Zinnia spp.) – Attract butterflies, with a long blooming period from late spring to early fall.
4. Impatiens (Impatiens spp.) – Ideal for shady spots, with continuous blooms from spring to fall.
5. Snapdragons (Antirrhinum majus) – Tall spikes of flowers that bloom in cooler spring and fall months.

Planting Tips:

• Soil Preparation: Amend the soil with compost to improve drainage and nutrient content, essential for subtropical climates.
• Watering: Install a drip irrigation system for efficient water use, especially important during hot, dry periods.
• Mulching: Apply a layer of mulch around plants to help retain soil moisture and suppress weeds.
• Spacing: Arrange plants according to their mature size to ensure proper air circulation and prevent overcrowding.

Seasonal Care:

• Spring: Plant annuals and check perennials for any winter damage. Begin regular watering as temperatures rise.
• Summer: Monitor plants for pests and diseases. Deadhead spent flowers to encourage more blooms.
• Fall: Plant or transplant perennials. Remove annuals after the first frost and prepare the garden for winter.

This plan should create a lush, flowering garden from March to October, with a mix of perennials and annuals that cater to the subtropical climate. Adjust the plant varieties based on local availability and your personal preferences for color and texture.
