June Garden Tips

Hello Friends, Neighbors, Fellow Gardeners,

It’s summer and this June there are plenty of opportunities to enjoy the outdoors!  Here are some garden tips, educational opportunities, and events for June. Events include Brookside Garden’s Wings of Fancy, Sandy Spring Museum’s Strawberry Festival, Brookside Garden’s Twilight Concert Series, lots of events at the Agricultural History Farm Park, Field & Fiddle 2017, Heritage Days, and more!


  • Check out plants going on sale.
  • Peruse fall bulb catalogs.
  • Order spring-flowering bulbs to arrive for planting this fall.
  • Plan who is going to water plants during your vacation.
  • Plan where fall bulbs will go.
  • Take photos and update your garden  journal.
  • Inspect your garden hose for leaks and tighten all connections.
  • As the heat and humidity move in, take it easy by working in the morning or early evening to avoid intense sun and humidity. Leave the big projects for this fall. For now, concentrate on maintaining the beds you’ve already established and nurturing your new plantings.
  • Support our local farmers! Visit a local farmers’ market near you. Download Montgomery County’s Office of Agriculture Farmer’s Market Flyer to find a farmer’s market near you. Or visit the main Montgomery County Farmers Market website.
  • Go on a local house or garden tour to see what plants are thriving in other’s area home gardens:

Flowers and Groundcovers:

  • Deadhead spent flowers to encourage reblooming.
  • Remove spent lilac and rhododendron blossoms.
  • Direct-sow annual flower seeds.
  • Water transplants deeply when dry.
  • Pinch buds of fall-blooming plants (asters, mums, Joe-Pye weed).
  • Prune azaleas directly after blooming.
  • Fertilize your azaleas and rhododendrons and monitor them closely for any lacebug damage.
  • Take cuttings from azaleas and roses to start new plants.
  • Spray roses with Neem oil every two weeks.
  • Start a sunflower patch with help from a few kids.
  • Stake tall plants.
  • Tie-up climbing roses and other wandering vines.
  • Try a few new tropical plants on your patio.
  • Check on your container plants daily and keep them well-watered.

    Blue False Indigo-Baptisia australis
    Baptisia australis
  • Baptisia is a native plant and is deer-resistant. Not only does it have beautiful flowers, but handsome foliage and interesting seedpods in the fall. | HGIC
  • Cut a few flowers to enjoy at your workplace.
  • Fill in bare spots in the garden with annuals.
  • Cardinal flower (Lobelia cardinalis) is a nice companion plant to ferns and is an excellent nectar plant for butterflies, hummingbirds and bees. | HGIC
  • Heliopsis
    Heliopsis helianthoides

    Heliopsis helianthoides is a native perennial which does best in full sun. It blooms from June to August. You can cut the stems back by 1/3 to 1/2 in early June to reduce the height. Remove spent flowers to prolong blooming. | HGIC

  • Aphids are common plant feeding insects Low aphid numbers usually do not result in plant damage. However, large aphid populations can cause wilting, yellowing, and curling of leaves. |  Aphids on Ornamental Plants, HGIC
  • Pests to watch for: aphids, 4-lined plant bug, lace bug, spidermites, slugs, snails, whiteflies
  • Diseases to watch for:  Blackspot on roses; powdery mildew, rust, bacterial diseases.
  • See UMD’s HGIC’s June Flower tips for more details.

Trees and Shrubs:

  • Transplanting azaleas still is possible.
  • Take soft wood cuttings of plants to propagate.
  • Directly after blooming, prune flowering shrubs and vines.
  • Water newly planted trees and shrubs weekly or as needed.
  • Contact a certified arborist to have your trees’ health inspected.
  • Shape your evergreens and hedges.

    Yellowood (Cladrastis kentukea)
  • Yellowwood (Cladrastis kentukea) is medium-sized, deciduous tree with fragrant, white flowers in the spring. It also has nice fall color. | HGIC
  • Prune long shoots on shrubs to keep plant neat looking.
  • Prune flowering shrubs as their flowers fade. Last chance to do so for fall-blooming camellias.

    Galls on Maple leaf
  • If you must mulch: Remove old mulch and then add 2″ to 3″ shredded pine or pine needles, keeping 3″ away from trunk.
  • Galls may disfigure twigs and foliage, but they do not seriously affect the health of trees and shrubs. Chemical control is usually not recommended. | (photo credit HGIC, UMD)
  • Soil test established trees that have not been performing well.
  • Keep mowers and trimmers away from trunks!
  • wintercreeper

    Two new additions to the Maryland Department of Agriculture invasive plant list: Euonymus fortunei (wintercreeper), Lonicera maackii (Amur honeysuckle). See for details.

  • Here are some more fruit and vegetable gardening tips for June from UMD’s HGIC.


  • Sharpen your lawnmower blade.
  • Mow in the early evening and cut off no more than one-third of the grass height at one time. Leave clippings on the ground to provide nutrients.UME_Turf_Fertilizer_Recommendations
  • If you have a zoysiagrass lawn, after the spring green-up, starting in June, is the primary time to fertilize if needed. The UMD Extension recommendations for turfgrass fertilization, consistent with the 2011 Maryland fertilizer law, are here: Turfgrass Maintenance Calendars for Maryland Lawns | UMD
  • Crabgrass has germinated. It is now too late to apply a pre-emergent herbicide. Small patches of crabgrass can be controlled during the growing season by pulling it out by hand or applying a post-emergent herbicide as a spot treatment.” | Crabgrass, HGIC
  • Apply pre-emergent weed control such as corn gluten.
  • Turn your compost pile weekly and don’t let it dry out. Work compost into your planting beds.

  • Be vigilant for mosquito breeding spots—any standing water from a bottle cap to blocked gutters and clean them up immediately.
  • Put out slug traps around your vulnerable edibles and hostas.Tick_season-guide
