Mid Summer Garden Rescue

The poor garden this summer! Extreme heat, no rain, blazing sun, then sudden torrential storms with incredible winds. All this and more have left gardens in a sad state. It’s time for a rescue. Here’s my list of fixes and tips to help reclaim their health and beauty.

Trim out all dead and diseased branches on bushes and trees. If left alone this could attract insets and/or further spread the disease.

Start by clipping out dead branches on bushes and trees. Next (depending on how much is affected), trim out the bad parts, or completely cut back perennials as well as annuals. Make sure to collect and recycle your trimmings. In the humidity which comes with late summer, it is easy for fungus and insects to infect large clippings on the ground. Adding them to a compost pile will heat them so this doesn’t happen. In my yard, I am completely cutting back the foliage on all of the daylilly, yarrow, iris, and lamb’s ears, which will resprout fresh new foliage and look terrific until frost.

I will trim out many small branches on the Japanese hollies and junipers, and a significant number of dogwood limbs, too.

I suggest raking through the mulch to make sure that it has not compacted too much, and if you are in a drought area, start watering your foundation bushes with a soaker hose if you haven’t already.

When your lawn goes into a dormant state due to severely high temperatures combined with a drought, it is best to wait until temperatures have receded before resuming watering and/or feeding.

The grass in the yard has gone completely dormant here due to the lack of rain and the heat. Rather than stress it by trying to force it to grow, I will let nature tell me when it’s time to regenerate. I must say that in all the years I’ve been gardening, I don’t remember a year that has stressed the grass so much. I caution against adding any mid-season fertilizer this year. It may help to lightly add a 1/2 inch of compost to the lawn to help protect the roots. Until the temperatures are back below the 90’s I am wary of doing much else. As soon as the temperatures are lower I will start watering unless we receive significant rainfall.

The flowers that I have in pots this year are tried and true. I planted only geraniums, which I know to be more drought tolerant than many other flowers. Tip: plant two pots for every one that you need in an exposed focal area like the front door. Put one pot on the front porch and one in a less exposed area (under the deck in my case). Rotate them back and forth each week. That way they are given a break from the harshness of the weather extremes and are able to stay healthy. Also be sure to turn your pots at least 1/4 rotation each week, so that they don’t grow crookedly towards the sun. This is especially true if you have potted evergreens that you display year round.

This is an example of "sucker" branches. They are ugly and can actually draw the nutrients out of the tree if left alone. It is best to keep them trimmed out.

Many trees will develop “sucker” shoots from the trunks or branches this time of year. They are very unattractive and provide no benefit to the tree, and they can actually harm the tree if left alone. I like to take a sharp pruner and trim them out. You may need to check every month or two for a re-occurrence.

This is also the perfect time to trim back wisteria. (Remember January and July for hard pruning on wisteria.) Mine grows as much as 3 to 4 feet in a week, so I do lots of mini-prunings to keep it in shape. If you are growing chrysanthemum or sedum, this is also the last time for pruning back the height before blooming. I like to take mine down by a third. By doing that you will have many more blooms on a much stronger, more compact plant which will be less prone to splitting open in the rain.

I hope your yards and gardens are surviving this hot, dry summer. If you have any tips you would like to share on this subject, send them along and I’ll be sure to print them. Here’s looking forward to some healthy green color coming back!
