At Donaldson’s Greenhouse & Nursery, we love being your go-to source for everything green and growing. As June kicks into high gear, our team is hearing lots of questions from customers navigating the transition from spring to summer gardening. From watering woes to persistent pests, we’ve rounded up your top concerns this month and paired them with expert advice to help your garden thrive right here in Hackettstown and the surrounding area.

1. How Often Should I Water My Plants in June?

Answer: As temperatures rise, so does the need for consistent moisture—but more isn’t always better. A good rule of thumb? Water deeply and less frequently. This encourages roots to grow deeper, making plants more resilient during hot spells.

  • Early Morning Wins: Watering before 9 AM helps prevent evaporation and gives leaves time to dry out, minimizing disease.

  • Check the Soil: Stick your finger 2 inches into the soil. If it feels dry, it’s time to water.

  • Mulch Matters: Applying a layer of mulch around your garden beds conserves moisture and regulates soil temperature.

Donaldson’s Tip: If you’re unsure about your watering habits, ask our staff about soil moisture meters—simple tools that make a big difference!

2. What Can I Do About Deer Eating My Garden?

Answer: Hackettstown and Warren County are prime deer territory, and hungry deer can wreak havoc on your plants.

  • Repellents Work: Try rotating different natural or chemical deer repellents every few weeks.

  • Choose Deer-Resistant Plants: Many native and fragrant herbs like lavender, yarrow, and Russian sage are less appetizing to deer.

  • Fencing Solutions: A 7- to 8-foot barrier is the most effective way to keep deer out, though even shorter fencing can help protect key areas.

Donaldson’s Favorite: Ask us about our selection of deer-resistant perennials and shrubs that still offer beauty and pollinator value!

3. What’s That White Dusty Stuff on My Leaves?

Answer: That’s likely powdery mildew, a common fungal issue in early summer, especially after cool, damp nights followed by warm days.

  • Air Circulation Helps: Make sure your plants aren’t overcrowded. Good airflow discourages mildew growth.

  • Water the Roots, Not the Leaves: Keeping leaves dry prevents spores from spreading.

  • Try a Fungicide: Neem oil, sulfur-based sprays, or potassium bicarbonate are effective organic treatments.

Ask Us: Bring a sample to our garden center and we’ll recommend the right solution from our curated plant care products.

4. Can I Still Plant Flowers and Veggies in June?

Answer: Absolutely! While the spring rush may be over, June is still a fantastic time to plant.

  • Annuals & Tropicals: Heat-loving varieties like marigolds, zinnias, coleus, and mandevilla thrive when planted now.

  • Vegetables: Beans, cucumbers, squash, and basil are great for succession planting this month.

  • Pollinator Favorites: It’s not too late to start your butterfly or bee garden with native perennials and nectar-rich blooms.

Just In: Stop by Donaldson’s for fresh shipments of summer-ready annuals and veggie starts!

5. Are Hanging Baskets and Containers Hard to Keep Alive in Summer?

Answer: They do require more attention, but the results are worth it!

  • Water Daily: Especially on hot days—container soil dries out faster.

  • Feed Regularly: Use a water-soluble fertilizer every 1–2 weeks to keep blooms coming.

  • Deadhead Spent Flowers: This encourages continuous flowering and keeps your baskets looking fresh.

Pro Tip: We offer beautiful pre-planted hanging baskets and patio containers grown right here at Donaldson’s—ask us how to care for yours!
