Wisconsin Gardener’s Tips for July 2024

i 3 Table Of Content

As summer reaches its peak, it’s time to give your garden some extra care to ensure it thrives in the heat. Here are some essential tips for July:


Deep watering once a week is crucial to help perennials cope with drought conditions. This practice encourages deep-rooted growth, which is vital for their survival during hot Cedarburg summers. Be sure to water early in the morning to minimize evaporation and maximize absorption. Mulching around your perennials can also help retain moisture and keep the soil cool.


Keep your shrubs healthy by treating any fungus with fungicide, but remember that Rust cannot be treated. Regular inspections will help you catch any issues early, especially in the humid Wisconsin climate. Pruning away affected areas can prevent the spread of diseases. Additionally, applying mulch around the base can help maintain soil moisture and reduce stress on the plants.


To prevent Rhizosphaera Needle cast in spruce trees, ensure good airflow and consider early fungicide treatment. In Cedarburg’s humid conditions, this proactive approach can save your trees from significant damage. Regularly thin out branches to improve air circulation. Watering at the base of the tree rather than from above can also help reduce the risk of fungal infections. If you’re mulching around the trees, remember to avoid volcano mulching—piling mulch against the trunk—as it can cause rot and invite pests; instead, spread mulch evenly to the tree’s drip line.


When it comes to your lawn, consider your options: seeding is a cost-effective and low-maintenance choice, while sod provides immediate grass cover, albeit at a higher cost. Seeding in July can be challenging due to heat, so ensure the soil remains consistently moist. Sod, on the other hand, offers quick results but requires diligent watering to establish roots. Whichever method you choose, proper lawn care will keep your grass lush and green throughout the summer.

Additional Tips

  • Keep an eye out for pests and treat them promptly to prevent damage. Cedarburg’s summer heat can bring about various pests, so regular monitoring is essential.
  • Mulch around plants to retain moisture and suppress weeds. This simple step can significantly improve soil health and plant resilience.
  • Prune any dead or diseased branches to promote healthy growth. Regular maintenance ensures that your plants stay strong and vibrant.
  • Consider planting heat-tolerant and drought-resistant varieties to reduce water usage and maintenance.
