Step-By-Step Planting Guide
Follow these steps for success with the best flowers to grow in New Jersey. Timing and soil preparation matter most.
- Test your soil – New Jersey soils vary widely. Get a pH test from your county extension office. Most flowers prefer pH 6.0-7.0.
- Amend as needed – Add compost to clay soil for drainage. Add organic matter to sandy soil for moisture retention.
- Choose the right location – Match sun requirements. Full sun means 6+ hours daily. Part shade means 3-6 hours.
- Plant at the right time – Perennials go in spring or fall. Annuals go in after the last frost, usually mid-May.
- Water deeply – New Jersey gets about 45 inches of rain yearly, but summers can be dry. Water 1 inch per week if needed.
- Mulch – Apply 2-3 inches of mulch to retain moisture and suppress weeds. Keep mulch off plant stems.
- Fertilize lightly – Use a balanced fertilizer in spring. Too much nitrogen causes leaves but few flowers.
Common Problems And Solutions
New Jersey gardeners face specific challenges. Here’s how to handle them with the best flowers to grow in New Jersey.
Deer Damage
Deer are common in suburban and rural areas. They eat tulips, hostas, and daylilies. Use deer-resistant plants like lavender, Russian sage, and coneflower.
Powdery Mildew
Humidity in July and August causes mildew on phlox and bee balm. Space plants for air circulation. Water at ground level, not on leaves.
Clay Soil
Northern and central New Jersey has heavy clay. It drains slowly and compacts easily. Add gypsum or compost to improve structure. Choose plants like coneflower and black-eyed Susan that tolerate clay.
Japanese Beetles
These pests attack roses and other flowers in midsummer. Hand-pick them in the morning. Use neem oil as a deterrent. Avoid traps that attract more beetles.
