Gardening tips for creating and maintaining a successful garden through summer

Gardening Journeys — June 2022

This spring has been unpredictable. If your veggies and flowers are slower than usual, you are not alone. It has been so cold and cloudy. Most plants are waiting for summer to bloom. And many people have experienced frost damage. If that happened to you, you have plenty of company.

Here are some gardening tips for June and July:


Speaking of frost, you can protect your young vegetables by having some frost cloth (row cover) on hand to place over the crop overnight or when needed.

Water vegetables early in the morning to allow the leaves to dry quickly.

Prune your lilacs, forsythia, rhododendrons and azaleas after the flowers fade. However, if new growth has already started, wait until next year after the bloom. These shrubs bloom on old growth. Prune too late and no blooms next year.

The growing season is here, so time to fertilize your perennials, shrubs, and ornamental trees. You can fertilize once during the season with a mixture of 10-6-4 or 20-10-5. You do not need high numbers for phosphorus or potassium.

Turf grass — to increase the water holding capacity and reduce water use, time to aerate the lawn. This process also removes compacted soil, stimulates new growth, and increases water and nutrient flow to the roots. After aeration, you can spread about a quarter inch of fine compost. Rake it in. Lawns can also be fertilized through June and July if we don't get too hot!

Plant perennials, annuals, shrubs, and trees during the growing season, and before intense heat.

The last of the apple blossoms are falling, so now is a good window to spray your fruit trees. If the frost damage was too great, (check your blossoms and stems for fruit development), no need to spray this year if no fruit. If yes, wait 10 days after natural petal fall and spray with Neem oil or Spinosad to prevent codling moth.


8. Deep water your perennials, shrubs and trees every five to seven days.

9. Plant some flowers to attract beneficial insects such as ladybugs and bees. Examples include marigolds, fennel, dill and roses.

10. Pinch back and deadhead annuals to keep them in full bloom.

11. Bird netting can be installed to protect berry crops.

12. Row cover can also be used to protect your vegetable garden from flying insects.

13. Some vegetables require consistent moisture to produce their best: including tomatoes and potatoes.

The Oregon State University Extension Service offers a free publication titled "Project Happy Apples." The newsletter is free when you sign up online for an electronic copy. If interested, get it at this website:, and scroll down to Project Happy Apples.

They also offer a newsletter "High Desert Gardening," which provides more detail than possible to list in a monthly column. It is also available for a modest fee at:

The Central Oregon Master Gardeners, OSU Extension and city of Bend are hosting a Water Wise Field Day Event in Bend at Hollinshead Park on Sunday, June 26 from 9 a.m. to 2 p.m The event incudes some half hour presentations on water saving methods and includes numerous vendors. Registration will be required for the presentations. The event is in the final stages, so watch the OSU/Deschutes website.

July begins the garden tour season. My favorite is the High Desert Garden Tour, put on by the OSU Extension/Deschutes office. Mark your calendar for Saturday, July 16. The tour will be in Bend this year, feature six home gardens, and is self-guided for a cost of $10 per ticket. For more information visit their website at:
