WhatPlantZone 7 gardeners need to focus on planting, pruning, and harvesting tasks in July to prepare for the summer heat.
Planting in July
July is not too late to plant some heat-tolerant vegetables and flowers. Consider these options:
- Vegetables: Solanum lycopersicum (tomatoes), Cucumis sativus (cucumbers), and Brassica oleracea (kale).
- Flowers: Zinnia elegans, Cosmos bipinnatus, and Celosia argentea.
Heat-Tolerant Plants
Choosing the right plants is crucial for a successful garden in July. Identify heat-tolerant plants to ensure your garden thrives. Some examples include:
| Plant Name | Heat Tolerance | Water Needs |
|---|---|---|
| Agave americana | High | Low |
| Salvia nemorosa | Medium | Moderate |
| Lavandula angustifolia | High | Low |
Pruning Tasks
Pruning is essential to encourage healthy growth. Focus on:
- Deadheading: Remove spent blooms to promote new flowers in plants like Rudbeckia hirta.
- Pruning Shrubs: Trim back overgrown varieties such as Hydrangea macrophylla to maintain shape.
- Cutting Back Perennials: Trim back stems of perennials like Coreopsis verticillata to encourage re-blooming.
Harvesting
July is peak harvesting time for many vegetables. Pay attention to:
- Tomatoes: Harvest fruits when they are firm and fully colored.
- Cucumbers: Pick them while they are still young for better flavor.
- Kale: Harvest outer leaves, allowing the plant to continue growing.
