Gardening Olympics – 2012′s Gold Medal Winners Are…..

It’s time for the Summer Olympics! Garden Olympics that is, and this summer had some clear winners despite the tough climate. There were gold medal winners in many categories – bushes, herbs, tropicals, vines, ground covers and annuals. I am going to show you what excelled this season in my garden.

This mango colored hibiscus is a definite gold medal winner. It has had prolific blooms and foliage all summer.

In the tropical category, I give the gold medal to this beautiful mango colored hibiscus. It has maintained beautiful deep green glossy foliage, and has at least half a dozen flowers every day. There are so many varieties of hibiscus, both tropical and hardy, and a wide choice of colors to boot, it makes them a terrific choice wherever you want a splash of color. I find that mine do best when in the morning sun, with filtered shade in the afternoon.

 

 

 

 

The mahonia, or false grape as it is sometimes called, adds a beautiful texture in the garden.

Where bushes are concerned, it is hard to deny that the mahonia is quite amazing. It is also sometimes called a false grape because of the clusters that you see in the picture here. The display of “grape clusters” was beautiful in the early summer, and the striking contrast in texture that it provides to the foundation plants is beautiful in comparison to the small leaves of the boxwood and azalea bushes in the garden. One note of caution: they have very sharp leaves, so use gloves when working on them. In the early part of the year there are sprays of tiny yellow flowers which are scented like lily of the valley, and that alone might get my gold medal award. Other very noteworthy bushes were the knockout roses and the nandinas, both of which were exceptionally gorgeous this summer.

This vibrant magenta colored geranium and the variegated ivy have thrived this season.

I give this year’s annual and ground cover awards to the geranium and variegated ivy. They have both done exceptionally well despite the fact that they are in the full sun and in a container. They remain my number one choice in a hot dry climate and are very showy even from a distance. This is the second year for these very hardy ivies. I have left them in the pot throughout the year, just changing out the flowers seasonally. The geraniums will be lifted out at the end of summer and stored in trays in the garage, where the temperature remains above freezing over the winter. I have used the same geraniums for many years, so they are also winners in the budget friendly category!

 

Some of the spectacular herbs this year, clockwise from top left: lemon balm, catnip, sage, and chives.

In the “edible” category I give the nod to the Catnip in my herb garden. I grow it each year in the same pot. It self seeds, so once you have it you never need to purchase it again. This year was a banner year, the leaves were huge, and were very much enjoyed by the kitties. I must also say that all the herbs in the garden both annual and perennial have been spectacular this season, but none as absolutely noteworthy as the Catnip.

The beautiful mandevilla vine winds itself up the post, needs almost no care, and flowers in abundance!

Last but not least, the plant which drew the most compliments this summer was the mandevilla vine that I grew on a tall lantern post near the front walk. It was constantly covered in soft pink flowers, and twined itself around the lantern post with no human help. People walking by asked about it, and I did see many others being planted and thriving in my neighborhood. It’s always nice to have a carefree, reliable, beautifully flowering specimen to welcome you home. Let me know what deserved the gold medal in your garden this year, I’d love to hear!

 

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!
