April in Nashville is a time of full-blown spring awakening. The last frost date has usually passed by mid-month, and warmer temperatures bring rapid plant growth. It’s the perfect time to transition your garden into full production while maintaining essential care routines. Here’s what to focus on in your garden this April.
1. Transplant Warm-Season Vegetables
Now that the risk of frost is nearly gone, it’s time to move your indoor seedlings outdoors. Start hardening off plants like:
- Tomatoes
- Peppers
- Eggplants
- Cucumbers
Gradually expose them to outdoor conditions over a week to prevent transplant shock.
2. Direct-Sow More Vegetables
With soil temperatures warming up, April is the right time to directly sow warm-season crops such as:
- Beans
- Corn
- Squash
- Melons
These fast-growing plants will thrive in the increasing warmth of late spring.
3. Continue Pruning and Deadheading
Early spring bloomers like forsythia and azaleas should be pruned right after they finish flowering to encourage strong growth for next year. Also, deadhead spent flowers from perennials to prolong their blooming period.
4. Maintain and Feed Your Lawn
April is a critical month for lawn care:
- Apply a balanced fertilizer to promote lush growth.
- Overseed any thin patches to ensure a thick, healthy lawn.
- Begin regular mowing as needed, but avoid cutting the grass too short.
5. Mulch Garden Beds
A fresh layer of mulch helps retain soil moisture as temperatures rise. Apply 2-3 inches of organic mulch around plants to suppress weeds and regulate soil temperature.
6. Watch for Pests and Diseases
Warmer weather means increased pest activity. Keep an eye out for:
- Aphids on vegetables and flowering plants
- Slugs and snails in damp, shady areas
- Powdery mildew on susceptible plants like squash and roses
Use organic pest control methods like neem oil, insecticidal soap, and companion planting to keep your garden healthy.
7. Plant Herbs and Flowers
April is a fantastic time to plant herbs like basil, cilantro, and parsley, as well as annual flowers such as marigolds and zinnias. Companion planting flowers with vegetables can help attract pollinators and deter pests.
8. Install Trellises and Supports
If you’re growing vining crops like peas, beans, or cucumbers, set up trellises or cages now. Providing support early will prevent damage to plants as they grow.
9. Start a Compost Pile
With plenty of yard clippings and kitchen scraps, April is a great month to start or refresh a compost pile. A well-maintained compost system will provide nutrient-rich material for your garden throughout the season.
10. Stay on Top of Weeding
Weeds grow rapidly in the spring and can compete with your plants for nutrients. Regular weeding sessions will keep your garden tidy and prevent invasive species from taking over.
By taking these steps in April, you’ll set up your garden for a successful and productive growing season. Whether you’re tending vegetables, flowers, or a lush lawn, these tasks will ensure your garden thrives well into summer.
Happy gardening!
