These Garden Weeds Should be Sprayed–Not Pulled—Here’s Why…

Frances walked through her landscape garden with me, pointing out some of her maintenance concerns. She said, “I would like for you to hand-weed this area.”

“I don’t think that’s a good idea,” I replied.—Here’s why I said that:

There are a number of weeds that are most pervasive and undesirable in the landscape garden. These plants are so survival oriented that they spread their roots out for quite a distance. When you pull one of them as a weed it will break off from these adventitious roots which will then sprout on their own, coming up all over the place (the more you pull the more you get). If you spray these weeds with a good weed killer they will die, roots and all.

I wrote an earlier article on weed spraying techniques, Click Here: Killing Weeds in the Landscape Garden I am sure that you will find that information helpful.

If left to grow, these vines have the ability to infest and totally destroy your special shrubbery. Here are some of them:

1. Cow itch, (trumpet vine, hummingbird vine)

In the south it's called "cow itch" also trumpet vine or hummingbird vine

I loved what Wikipedia said about cow itch:

The vigor of the trumpet vine should not be underestimated. In warm weather, it puts out huge numbers of tendrils that grab onto every available surface, and eventually expand into heavy woody stems several centimeters in diameter. It grows well on arbors, fences, telephone poles, and trees, although it may dismember them in the process. Ruthless pruning is recommended. Outside of its native range this species has the potential to be highly invasive, even as far north as New England. The trumpet vine thrives in many places in southern Canada as well.”

2. Saw briar (smilax)

One of the most difficult weeds to eradicate is the saw briar. The southern Indians used to dig the roots of this plant and eat them like potatoes.

This weed is appropriately named saw brier. More technically, "Smilax"

3. Poison ivy

I assume that we all know the consequences of pulling this weed. I found it interesting that my Dutch brother-in-law pulled weeds in Tennessee and then flew to Amsterdam. The next day in Holland he broke out in a terrible itchy rash and had to go to the hospital. The doctors in Holland didn’t know what was wrong or how to treat it so they had to call The U.S. You guessed it—poison ivy

4. Virginia creeper

Virginia creeper is a pretty plant. My Swiss mother-in-law loves the way it looks growing up a wall. Apparently people in the northern U.S. and in some parts of Europe actually cultivate this noxious weed. Grown up the side of a house, this plant will eat out mortar joints and cause wood to rot and fall apart. In the garden it will cover and choke your desirable plants.

5 Muscadine

In the right place this grape vine is desirable. The fruits make wonderful jellies and wines. However, in the garden it will take over trees and shrubs in a rampant manner while searching for light. Remember, “a weed is a plant that is in the wrong place.”

6. Honeysuckle

There are some desirable cultivars of this plant but the wild variety can be a nuisance. The blooms do smell good and I have fond memories from my childhood that deal with pulling the bloom apart and sucking on the sweet nectar therein. Now, though, I routinely remove it from azaleas and hollies in people’s yards.

And to finish off this article I am including a picture of the beautiful trumpet flower of the cow itch plant. You can see why it is also called “hummingbird vine.”

Prune Azaleas in May-June. Fertilize Azaleas, Avoid and Kill Poison Ivy

There is a rather old planting of George Tabor azaleas on the side of our driveway and Sweetie has been reminding me relentlessly for months that they need to be pruned and shaped. The last week in May or the first week in June is just the right time for the job. Here’s the “before” picture:

There’s a reason for pruning azaleas the first week of June, too. One of my fun mental exercises for years has been to listen to the old people’s comments on growing plants and then to figure out why their techniques work. Please note that Encore azaleas are treated differently.

As for the time to prune azaleas, it’s interesting. In June, the plants have finished blooming and are entering their peak growth stages. The azalea will set its bloom for the following spring in August. The blooms are commonly borne on the growth tips and pruning at the right time increases the number of tips so that you will end up with a more compact plant and many more blooms. You may wish to read my article on Pruning as an Art Form for a concise description of what happens when you prune a plant.

One of my goals is to open up the plant canopy to allow more light to reach the inside. This will promote lower growth which will strengthen the plant. I try to keep the sides of the plant neat and pretty but I never hesitate to open up a “hole” in the top. New growth will fill this in rather quickly.

I’m a little over six feet tall and this plant was a bit taller than that. I try to watch for danger when I’m working in overgrown shrubbery and my diligence paid off this time. As I worked, a giant poison ivy vine was sneaking up on me. I saw it just in time and backed up. I planned to approach it slowly and carefully.

The only really good way to get rid of poison ivy is to spray it but I don’t want to get any spray on the azalea so I placed a garbage bag over the azalea and carefully moved the poison ivy stem on top of it.

Using a generic form of Roundup with glyphosphate as the active ingredient, I sprayed the tip of the plant. The chemical will enter the system of the plant and should move on down the stem and kill the roots.

Spray with very low pressure to cover weed but to not get it on the good plant.

This is a good time to fertilize the azaleas, also. I grabbed a bag of azalea fertilizer at my local nursery. The analysis is 9-15-13 with the addition of iron, copper, manganese, and zinc. If you don’t know about fertilizer labels, they are explained in my article “Choosing the Right Fertilizer”

And here’s the “after” picture. Remember what I always say—“Happy Wife, Happy Life.” Now she will be free to find something else to remind me to do.
