Flower Planting Guide & Growing Tips
Planting Guide by Flower Type
A flourishing flower garden starts with a few thoughtful choices. When you match each variety to the light, soil, and climate in your yard, you set the stage for strong plants and generous blooms. With well-prepared soil and a little steady care through the season, your flowers will reward you with color, life, and beauty from the first warm days of spring until the final notes of autumn.
Choosing the Right Flowers for Your Garden
Every garden has its own rhythm. Some bask in full sun from morning to evening; others stay cool and shaded under trees. Take a moment to notice your light exposure, soil texture, and USDA Hardiness Zone. These small observations make it easier to match each flower to the conditions where it will flourish.
Native flowers offer dependable beauty with minimal fuss, while heirloom and specialty varieties can add something truly memorable. Each flower brings its own set of needs, and choosing varieties that fit your environment leads to stronger plants and more reliable blooms.
Preparing the Soil for Flower Seeds and Plants
Healthy soil is at the heart of every thriving flower garden. Most flowering plants appreciate loose, well-draining soil enriched with organic matter. Working in compost or well-aged manure before planting helps roots settle quickly and encourages generous flowering.
Follow recommended spacing so plants have room to breathe. Good airflow helps keep foliage dry and reduces the likelihood of disease, especially in humid climates.
Caring for Flowers Grown from Seed
Once your seeds or transplants are in place, steady care carries them through the season.
- Watering: Keep young seedlings consistently moist, adjusting for rainfall, heat, and the specific needs of each variety.
- Mulching: A light layer of mulch preserves moisture, keeps roots cool, and discourages weeds.
- Deadheading: Removing spent flowers encourages fresh blooms and keeps plants looking neat.
With these simple steps, your garden becomes a welcoming space for color, pollinators, and seasonal interest from early spring to fall.

Flower-by-Flower Growing Tips
Use these notes alongside the charts above for a complete picture of each flower’s growing habits. These practical tips support planning, planting, and seasonal care.
Ageratum – Remove spent blooms to prolong flowering. Keep well-watered during hot, dry periods.
Alyssum, Sweet – Shear plants lightly to encourage extended bloom.
Aster – Rotate planting locations each year to reduce the chance of Aster Wilt.
Begonia – Bronze-leaf varieties tolerate sun well. Keep foliage dry and ensure good air circulation.
Chrysanthemum – Fertilize well. Pinch stems until July 15 for bushier plants and more blooms. Divide in spring.
Coleus – Remove flower spikes to maintain full, colorful foliage.
Crape Myrtle – Start seeds indoors in March for late-summer bloom. Hardy in the South; overwinter indoors in colder regions.
Dahlia – Blooms the first year from seed. Plant tubers 6 inches deep after frost; stake tall varieties.
Daylily – Easy to grow. Seeds sown in late summer bloom the following year in warmer zones.
Delphinium – Feed generously. Cut back flower stalks after bloom to encourage fall rebloom.
Gerbera – Start seeds in January for early-summer color. Provide full sun and steady moisture; overwinter indoors in colder climates.
Geranium – Seeds germinate at different rates; wait for full germination before transplanting. Protect seedlings with approved fungicide.
Hollyhock – Some bloom their first year; others need an early start for next-season flowers. Young plants perform best.
Impatiens – Ideal for shade. Begin blooming about three months from sowing; pinch once or twice for compact plants.
Lisianthus – After seedlings emerge, move to bright light and maintain temperatures of 80–85°F.
Marigold – Plant leggy seedlings deep so stems can root. Remove spent flowers to encourage continued bloom.
Pansy – Work soil deeply and enrich with humus. Prefers cool, moist, lightly shaded conditions.
Pardancanda – Handles challenging conditions well. Apply winter mulch north of Zone 7.
Portulaca – Start indoors or sow directly outdoors.
Primula – Prefers humus-rich, consistently moist soil.
Salvia – Reds shine in full sun; pastel shades tolerate light shade. Use fungicide on seedlings to prevent damping off.
Snapdragon – Pinch after the first bloom to encourage a second flush.
Strawflower – Cut when showing good color and hang upside down to dry.
Sunflower – Thrives in full sun. Large varieties produce edible seed for people or birds.
Vinca – Blooms reliably from June to frost; available in creeping and upright forms.
Zinnia – Choose a site with good airflow to minimize mildew.
