Fruits and Vegetables

It’s not too late to plant beans, cucumbers, tomatoes and other summer crops. Most vegetables thrive in containers on decks, patios or other small spaces.

Now is the time to stake or cage tomatoes. Keeping them off the ground will reduce pest problems, save space and make harvesting easier.

In mid to late June, you can control borers in squash, cucumbers and melons with Eight Insect Control.

Fruit trees need to be sprayed on a regular schedule to keep them free of insect and disease problems. Talk with our plant specialists about organic or conventional treatment options.


Move your houseplants outside to the deck or patio. Gradually introducing them to more direct sunlight will prevent the leaves from burning.

Gator Bags are a great solution to keep trees watered during the heat of summer. These are secured to the trunk of the tree, where they release the water slowly to the root ball over the course of 15 to 20 hours.

Prune azaleas and rhododendrons now, allowing time for them to grow and set flower buds later this summer.

Control spider mites on alberta spruce, azaleas and other plants using Bonide Systemic Insect Control or Bayer Advanced 3 in 1 Insect, Disease and Mite Control.

Check for bagworms on arborvitae and other evergreens. Use Thuricide or Monterey Garden Insect Spray at the first signs of activity.

Begin feeding your pond fish with a high protein food when temperatures rise above 70 degrees.

Fertilize water lilies and lotus once a month to encourage continuous bloom.

Hardy water lilies bloom only during the day, but annual tropical varieties include day and night bloomers. Plant both to enjoy the bloom during the day and in the evening. Night blooming tropical water lilies open their flowers at approximately 5 pm and close the following morning around 9 am.

Wildlife and Wildlife Management

Control deer foraging in your landscape plants with Bobbex, Milorganite and/or Deer Away.

Seasonal Care

Window boxes, hanging baskets and planters need to be watered and fertilized more frequently than plants that are growing in the ground this season. Try adding Soil Moist, a water-grabbing polymer, to reduce the frequency with which you will need to water your container plants.

As the heat of summer sets in, check all plants, especially newly planted ones, for water on a regular basis. Water deeply and thoroughly as needed.

Review our watering instructions to ensure your plants stay healthy and hydrated.

Gator bags provide a great way to keep trees watered during hot and dry months. These bags, which can hold up to 20 gallons of water, are secured to the trunk of the tree, where they release the water slowly to the root ball over the course of 15-20 hours.
