Crusade against Japanese Beetles
The very sound of the words, Japanese Beetles invokes irritation, frustration and gloom among Minnesota gardeners. We can see them in our minds chewing, crawling, and decimating our Roses, our tropical Hibiscus flowers, our Grapevines and….our souls!
Birch, Maple & Walnut tree Pruning

It emphasizes the importance of pruning in June and July to minimize sap bleeding. Proper developmental pruning is essential for tree health, including removing crossover branches and avoiding stub cuts. The article highlights the unique challenges posed by Black Walnuts due to juglone toxicity.
Mulch
Mulching offers numerous benefits for gardens, including moisture retention and weed prevention. Two types of mulch exist: inorganic, which is cost-efficient but nutrient-poor, and organic, which enhances soil health. Effective mulching requires proper application thickness and distance from plants to prevent fungal issues. Timing for mulching is flexible throughout the season.
Rose Pruning
Minnesota gardeners should be aware of distinct pruning techniques for three common rose types: climbing, hybrid tea, and shrub roses. Each type requires specific care in early spring and summer, focusing on deadheading and strategic cuts to enhance blooming while preventing diseases. Pruning generally concludes by mid-August for optimal growth.
Bringing Plants Indoors for Winter
Winter gardening is still possible by bringing outdoor container plants indoors, like hibiscus and begonias. Following proper steps for overwintering can be rewarding. It’s normal for plants to lose some leaves during acclimation, but they will likely regrow healthier leaves suited for indoor conditions.
