Garden Calendar Series – June/July/August

Published by Bucks Country Gardens in Lawn & GardenPlants

Having a Garden Calendar is a must! Every month there are new garden “to do’s.” As summer approaches, there is still much to do in the garden. It is the time to reap the benefits of your edible gardens and enjoy the full blooming wonders of your landscape. We put together a calendar of some of the most common garden “to do’s” for June, July, and August, to keep you organized and on track!


Spring is just about over and the garden is in full bloom! There is still time to harvest cool season veggies and planting warm season crops!

What to Plant:

  • • Plant warm season crop seeds: beans and corn. These will germinate and grow fast now that the soil is warm.
    • Most other warm season crops are normally in the ground by June, but if not, now is still a great time to plant: tomatoes (fertilize and stake these), peppers, eggplant, cucumbers, squash, melons, celery, corn, sweet potato, potato, and beans.
    • Planting successive crops of your cool season veggies will keep you fed through the season into fall: lettuce, spinach, radish, carrot, beets, onion, and chard.
    • Supplement annual herbs: thyme, rosemary, sage, and chives.
    • Add some seasonal color to beds with summer annuals. These will last until the waning days of fall.
    • Sow zinnia seeds for a late summer crop.


  • • Cut back early spring perennials that are done blooming.
    • Divide Irises once they have finished blooming.
    • Cover blueberries, raspberries, and strawberries with bird netting to protect the fruit.
    • Fertilize your veggie/container garden and tree/shrub beds.
    • Prune shrubs that have finished flowering.
    • Monitor all new plantings for water.

Don’t forget to bring your tools inside! Leaving them outside will expose them to unnecessary moisture.

Pest & Insect Control:

  • • Check flowering tropical plants and annuals for aphids and other pests.
    • Keep an eye out for bagworm on ornamental trees and plants. Apply a systemic insecticide or thuricide to plants every 2 weeks.
    • Monitor roses for pests and disease issues.


Many of the same things can also be done in July as you have done in June (if they are not done already). Now’s the time – begin harvesting your summer fruits and vegetables.

What to Plant:

  • • Continue to plant cool season crops every 2-3 weeks for continued harvest. They will bolt (go to flower) much faster during the heat of the summer, so time between planting and harvesting is cut shorter.
    • Plant seeds: lettuce, cabbage, broccoli, and cauliflower.


  • • Deadhead and trim back hardy geranium and delphinium after their first flush of bloom.
    • Continue fertilizing your perennials to decrease stress of plants during a long dry spell.
    • Make sure new and established trees and shrubs have a 2” layer of mulch to help conserve moisture.
    • Stake climbing annual vines (if you haven’t already).

Water! Water! Water!

  • • Things are heating up! Make sure to water during long dry spells.
    • Water annuals and container gardens early in the morning for optimum water retention.
    • Monitor all plants for water.

You can find a great selection of watering cans, hoses, and nozzles at Bucks Country Gardens all year-round. Our experts can let you know how much water your plants need or read our watering blog! We want to make sure your plants are well watered, so they are happy.

Pest & Insect Control:

  • • Keep an eye out for garden pests and diseases. This is the time you will start to see damage.
    • What you might see: white flies, mites, and squash borers, along with squirrels who like to eat everything!
    • Tomato and potato blight are also very common.
    • Check tomatoes for tomato hornworms. Removing the large green worms by hand is the best method for control.
    • Control pests with our Garden Pharmacy products accordingly to keep your plants healthy and happy. We have organic oil, spray, and solutions too!
    • To avoid damage to foliage, make sure you do not spray when temperatures are above 85 degrees.


Keep harvesting all your goodies. That’s what’s best about having an edible garden!

What to Plant:

  • • Continue to plant cool season crops every 2-3 weeks for continued harvest into the fall.
    • Also, add more carrots, cabbage, escarole, onion, and garlic for fall/winter/into next spring harvest!

Water! Water! Water!

  • • Again, the heat can suck your plants dry. Make sure to water during long dry spells.

Pest & Insect Control:

  • • This is still a time you’ll see damage. Keep an eye out for garden pests and diseases and treat accordingly.

As always, if you are unsure if and where the plant is infected, please bring in a sample in a sealed plastic bag, send in a picture, or contact us at Bucks Country Gardens for help with your concerns.


  • • Divide peonies and daylilies at the beginning of the month.
    • Avoid using weed control and fertilizers until September.
    • Continue deadheading gardens weekly.

Mulch to Do:

  • • Keep an eye on your mulch! It is common during hot dry spells for thicker layers of mulch to develop a crusty layer from a fungus that thrives in those conditions.
    • This layer will not let water through and further stress your plant material. If you see this, simply break the layer with a rake and water it down thoroughly.
