For the love (or otherwise) of ivy
Rick in Marshall (just South of Middleburg, Virginia, on Interstate 66) writes: 鈥淚 have an ‘English ivy problem!’ I’ve lived at my home for 35 years and I swear that I never planted even one sprig of this ‘weed.’ The ivy looks pretty but is very resistant to eradication. I have a brick veneered house and this [bad word] plant grows over my planting beds and crawls up the wall like invading locusts!鈥�
Yes, you鈥檙e in a world of trouble, Rickster, as it sounds like maybe you鈥檝e been waiting those 35 years to notice that your home is getting an Ivy League education. Oh 鈥� and many people have similar ivy problems that they also didn鈥檛 cause, thanks to a discarded house plant or birds eating and then “planting” the numerous berries that appear on mature plants in the fall.
Ivy is a tough plant to eradicate
Rick continues: 鈥淒o you have any suggestions about how to get rid of it without nasty chemicals? I’ve tried pulling up the roots and stems, but it always comes back.鈥�
You鈥檙e on the right track, Rickster, but not quite there yet. Instead of pulling, you need to cut each individual vine close to where it emerges from the soil. Roll up any ivy that isn鈥檛 attached to a hard surface as if you were rolling sod. Do not attempt to compost this mass 鈥� or even let it sit on the ground for any length of time. Bag it, let the bag sit in the sun for a week and then put the bag(s) out with the trash. Then wait for the rest of the aboveground growth to die off.
And I do mean “wait.” Do NOT try and pull it off your house while it鈥檚 still green and healthy or you鈥檒l damage that brick facade 鈥� or heck, even non-facade bricks.
Getting to the root of the problem
Once English ivy gets a foothold 鈥� or a roothold 鈥� it is difficult to eradicate. Its waxy coating sheds broad-leaf herbicides before they can do any harm; and systemic herbicides would endanger your other plants 鈥� and you. Because of that waxy coating, the only answer that doesn鈥檛 involve killing your other plants and increasing your cancer risk is to cut and pull.
Sever the vines as described above, soak the area well with plain water and then use a poacher鈥檚 spade to dig out each vines鈥� root system. Luckily, the roots are surprisingly shallow (as am I) and easy to get out completely.
As with the actual vines, do not compost the remains. Shake off as much soil as you can, then bag those roots and let the bag sit in the sun for a week before putting them out with the trash.
After the work is “over”
Roots: If you did a good job with that poacher鈥檚 spade (one of my top three all-time garden tools), there should not be any re-sprouting.
But just in case, be prepared with a medium-sized sprayer (one holding a quart or two). If you borrow the device from someone, rinse it out, fill it with water and then spray the contents on the street to get rid of any chemical residues. If new sprouts do appear, use the device to spray them with regular white vinegar from the grocery store. Wear gloves and protective eyewear and don鈥檛 spray on a windy day. And rinse the sprayer well afterward.
Dead vines: Again, be sure to let the portions of the vines that are attached to the house die off naturally. I know it鈥檚 going to look like the dog鈥檚 breakfast, but those vines are glued securely to the side of the house and could destroy your veneer. The longer you wait, the better the odds you won鈥檛 have to resurface the wall.
When the vines are really most sincerely dead, pull them slowly off the side of the house. Don鈥檛 yank or pull too soon or you鈥檒l damage the exterior.
There will probably be some strains left behind. There鈥檚 no agreement on how to remove them without damaging the surface, but my first choice would be a product called 鈥淢r. Clean鈥檚 Magic Eraser.鈥� I鈥檝e been told that these eraser-like cleaners can be highly effective on difficult outdoor stains.
Honey do 鈥� and don鈥檛!
It鈥檚 almost April and the smell of gardening is in the air!
To keep your lawn healthy and happy, replace your mower blade or get your old blade sharpened; this is the single most important thing you can do to achieve a good-looking turf this season.
You can now sow the seeds of lettuce and spinach directly outdoors, harvest the plants “cut and come again” style with scissors when they reach four to five inches in height; take off the top three inches and they will regrow for more cutting. (Or, if you have the room, sow fresh seeds every two weeks for the longest possible harvest period.)
Resist the urge to cut off the green leaves of flower-faded spring bulbs; without those leaves left intact to absorb solar energy, the plants won鈥檛 be able to produce flowers next year.
