UPDATE ON MONTHLY

LECTURE SERIES & MEETINGS 

Greetings OHS Members, gardening friends, and horticulture enthusiasts.  Summer has arrived and now that we are in the month of June, we would normally be looking at our last OHS monthly meeting for the season.  I am sad to report that, similar to recent months, the planned June meeting and social has been cancelled. 

 

It seems so long ago since we have been together.  I am sure that many of you share my disappointment that we have had to cancel all of our OHS meetings and activities since March due to the "social distancing, shelter-in-place, etc." guidelines provided by the CDC as a defense against this year's seemingly uncontrolled spread of the Covid-19 virus.    Whether we followed mandatory guidelines or optional recommendations, this season's difficult decisions to cancel OHS activities in order to minimize person-to-person contact were given careful thought, and were made in consideration for the health and well-being of all of our members, family and friends.

 

Without the benefit of a crystal ball, I am hoping that we will all be able to benefit from the much-anticipated recovery, and that we will have a chance to see things begin to return to normal this by fall.  We will provide updates on OHS activities as information is available.

                                 

Until we meet again, stay healthy and safe.  Happy gardening!

JUNE

Landscape

  • Water deeply; one inch per application.

  • Cultivate and mulch.

  • Protect trees from lawnmowers and weed eaters by mulching or using protective aerated covers.

  • Vigorous unwanted limbs should be removed or shortened.  Forks in young trees can be corrected to encourage a central leader.

  • Softwood cuttings of new growth of many shrubs and trees can be rooted.

  • Remain alert for insect damage. Spider mites, fall webworms. Cutworms possible.

  • Pine needle disease treatments are needed again in mid-June.

  • Find someone to water plants in the house and garden while on vacation.  Harvesting vegetables and mowing the lawn are a must and imply that someone is home.

  • Pinch back leggy annuals to encourage new growth.  Fertilize and water appropriately.

  • Feed established mums and other perennials.

  • Stake tall perennials before toppling winds arise.

Turfgrasses

  • Fertilize warm season grasses.

  • Seeding of warm season grasses should be completed by the end of June.

  • Brown patch disease of cool season grasses can be a problem.

  • Post-emergent control of crabgrass and summer annuals is best performed on young plants.

 

 

JULY

Vegetable Garden

  • Make fall vegetable garden plantings in late July. Fact Sheet HLA-6009 gives planting recommendations.

Lawn

  • Brown patch disease of cool-season grasses can be a problem. (HLA-6420)

  • Meet water requirements of turfgrasses. (HLA-6420)

  • Fertilization of warm-season grasses can continue if water is present for growth. (HLA-6420)

  • Vegetative establishment of warm-season grasses should be completed by the end of July to ensure the least risk of winter kill. (HLA-6419)

  • Mowing heights for cool-season turf grasses should be at 3" during hot, dry summer months. Gradually raise mowing height of bermudagrass lawns from 1 ½ to 2".

  • Sharpen or replace mower blades as needed. Shredded leaf blades are an invitation to disease and allow more stress on the grass.

Tree and Shrub

  • Control bermudagrass around trees and shrubs with products containing sethoxydim, fusilade, or glyphosate herbicides. Follow directions closely to avoid harming desirable plants.

Fruits

  • Continue insect combat and control in the orchard, garden, and landscape. (EPP-7306, EPP-7313, EPP-7319)

  • Check pesticide labels for "stop" spraying recommendations prior to harvest.

  • Harvest fruit from the orchard early in the morning and refrigerate as soon as possible.

Flowers

  • Divide and replant crowded Hybrid iris (Bearded Iris) after flowering until August.

General Landscape

  • Water plants deeply and early in the morning. Most plants need approximately 1 to 2 ½ inches of water per week.

  • Providing birdbaths, shelter and food will help turn your landscape into a backyard wildlife habitat.

  • Insect identification is important so you don't get rid of the "Good Guys." (EPP-7307)

  • The hotter and drier it gets, the larger the spider mite populations!

  • Expect some leaf fall, a normal reaction to drought. Water young plantings well.
