Preparing for Planting
Before placing seeds into the earth, gardeners should ensure optimal conditions for Sweet William to flourish. Proper soil preparation and selecting the ideal site are the cornerstones for a successful bloom.
Soil Preparation
Sweet William thrives in moist, yet well-drained soil. The gardener should aim to achieve a balance where water is adequate but not excessive, ensuring roots do not sit in water.
Incorporating organic matter such as compost can enhance soil fertility and texture.
A pH between 6.0 and 7.0 is ideal for Sweet William, so it may be necessary to adjust the soil pH accordingly.
Before planting:
- Test soil pH: Use a soil test kit to determine if adjustments are needed.
