I have found the quickest growing vegetable to be lettuce/greens in a tie with radishes
Will ivy growing up an oak tree eventually kill the tree?
It is not particularly effective. However roundup does sell a special herbicide for poison ivy.
it depends what type if leaves. If they are ivy then they are "strangeling" your tree and you need to get rid of them
I'm assuming the ivy is growing outside. It is very hard to get rid of ivy. Basically, you just have to pull it all up and dig up all of the roots. After your initial pulling and digging, if more grow, get it out as soon as you can. It is a lot of work, but eventually you will get all of it.
All English Ivy flowers. It has a juvenile form, which is the one which is most recognizable growing on walls; it also has an adult form (if the plant is allowed to grow out), which produces sprays of white flowers followed by black berries. Other varieties of "Ivy" such as Boston Ivy also flower, although the flowers may be a little less conspicuous.
This is an easy to care for, fast growing plant...can be grown in doors or in a moderate climate. The plant has bold green arrow head or heart shaped leaves that grow the same as a traditional ivy. Easy to root
One can find more information about growing an English Ivy from the following sources: Landscaping About, King County, Daves Garden, Wikipedia, BBC, Wild Flower, to name a few.
Cutting the connection between the part growing up the tree and the top of the roots and then eliminating the roots are ways to kill trunk-climbing ivy without killing the dogwood (Cornus spp) so affected. The roots may be removed by equipment, hand, or pesticide.
The Ostrich is the quickest bird.
Ivy can eventually cause damage to trees because of the extra weight loaded onto branches and also because it can act as a wind trap, especially during the winter when many trees lose their leaves.
