English Ivy, the classic vine that covers cottages and runs along brick walls, is an avid grower that can thrive in almost any condition. However, in certain situations, you may need to spur on growth a bit for your patch of ivy; prudent application of a fertilizer can be just what you need.
Use a liquid fertilizer, such as fish emulsion or crystal pellets that will dissolve in water. Liquid fertilizers will be easier to apply to the spreading and draping ivy than sprinkling dry fertilizers over the vines.
Mix the fertilizer with water according to the proportions indicated on the package. Use a watering can with a long spout.
Apply the fertilizer by gently moving the ivy back and using the spout to pour out the water-fertilizer mix at the base of the plants.
Fertilize at the beginning of the growing season, in early spring, when the weather begins to warm up. Fertilize again once or twice a month during the growing season, as liquid fertilizers tend to last only about 2 weeks. If your plant is healthy and growing well, once a month or once every other month may be adequate.
