Choose Healthy Plants
Choosing healthy plants at the garden center is the first step to a successful annual planting. Look for annual plants with these characteristics.
Healthy Plant Checklist:
- Healthy, bright white roots that fill out the pot
- Stocky, strong stems
- Many flower buds but few open flowers
- Good branching off the main stem
- No yellowing or spotted leaves
- No signs of insect damage
Preparing the Planting Bed
Annual plants require well-drained, fertile soil because they expend great amounts of energy on flower production. Planting beds should be prepared using the following steps to create a good environment for them to thrive.
Planting Bed Prep Steps
- Remove ground covers such as sod from the area using herbicides or digging out plants.
- Till area to a depth of 8-10 inches.
- Add and till in 4 inches of organic matter and any fertilizers recommended in your soil test report. Visit your local Extension Office for a soil test kit.
- Smooth soil and slope beds away from buildings. Slope the edges to improve drainage.
- Plant bedding annuals at the recommended distance on the plant label, taking care not to plant too deeply or shallowly.
- Cover the entire bed with 2 inches of pine bark mulch or straw. Be careful not to cover plant stems in mulch.
- Water as needed. Initially, plants should be watered every few days. Once established, plants should receive 1 inch of water per week if not supplied by rainfall.
