Great Garden Tips for June!
The month of June is the gateway to the sizzling summer season. Here are a few tips for keeping your gardens and lawn in tip-top shape through the hot summer months.
Shear certain spring blooming perennials
Some spring blooming perennials like Iberis (Candytuft), Alyssum (Basket of Gold), and Phlox subulata (Mountain Pink) should be sheared/deadheaded after they finish blooming to encourage bushiness and make the plants look neater in the garden. A good pair of hedge shears
is perfect for this job!
Trim back certain tall perennials to keep compact
Some perennials benefit from being sheared back by half or a third of their height in June. This not only keeps them more compact and bushy in the garden but also improves flowering by allowing more flowering stems to be produced. Below is a list of some perennials that can be sheared back in June. It includes many fall bloomers.
- Perovskia (Russian Sage)
- Gypsophila (Baby's Breath)
- Monarda (Bee Balm)
- Eupatorium purpureum (Joe Pye Weed)
- Helianthus (Perennial Sunflower)
- Miscanthus - The taller forms of Maiden Grass can be cut back if they traditionally flop over in your garden during the summer. Be sure to cut these grasses by June 10th or the bloom may be affected!
Cutting Back Daffodil foliage
June is the time when you can begin to remove daffodil foliage from your garden. Be sure to wait 6 weeks (after bloom) for the foliage to ripen before cutting it back. This gives the foliage a chance to feed and fortify the bulb for more beautiful blooms next spring. Once the majority of the foliage turns brown, you can carefully pull it off or cut it back.

on when to remove daffodil foliage.
Watch for disease in the garden
With all the wet weather we've been having lately, the incidence of disease is likely to increase over other years. Be on the look out for fungal diseases like rust on Hollyhocks and asters, botrytis on peonies, leaf spot on roses and other plants, and powdery mildew on many perennials and shrubs.
- Providing good air circulation around your plants by proper spacing and thinning will help reduce the incidence of disease in the garden.
- If fungal disease begins to become a problem, spray with an approved fungicide. Diagnose your problem and then choose a fungicide that is labeled for that particular disease. Always read and follow the label directions.
Be on the lookout for garden pests
I noticed lots of aphids clustered on the stems of some perennials in the garden the other day! These piercing and sucking pests can do some major damage to your plants. A great way to rid your plants of aphids is to spray with Bonide All Season's Oil or insecticidal soap according to the label.
Watch for signs of slugs and snails in the garden. Sluggo is a great product for ridding the garden of slugs and snails. It is easy to use and is safe to use in the vegetable garden and around children, pets, and wildlife.
Plant some beautiful container gardens
The frost danger is finally over! June is a great time to plant your containers.
Be creative! Don't be afraid to combine different plants such as annuals, tropicals, perennials, trees, shrubs, vines, and even vegetables. Tropical vines will provide a unique vertical effect by growing upright to give you height with flowers bursting outward facing you. The large leaved tropicals such as Elephant Ears, Cannas, and Banana plants make a dramatic statement with their huge colorful leaves. Even a Hosta with large textured leaves can become the focal point in a container garden. Watch Mark's video tip
on using hosta in containers. Containers aren't just for decks and patios either! Andre has many lovely BIG containers nestled around in his beautiful gardens. They are just stunning!
