Ivy is a woody vine that is usually grown as a groundcover. As it has a tendency to spread, if it isn't controlled by pruning it will soon take over any areas adjacent to where it is planted. If geranium were planted within ivy, it would soon be overcome and unable to compete with the vine for water and nutrients. Container-grown ivy, on the other hand, is easily controlled and provides a charming companion for the gaily colored geranium flower.
Fill the planting pot three-quarters full with potting soil, and water it until the excess water runs out of the bottom of the pot.
Remove the ivy and the geraniums from the pots in which they are growing.
Gently loosen the soil around the root balls of the plants and place them in the pot. Rearrange and adjust them until you achieve the look you want. Then backfill with soil, covering the roots of the plants and tamping down firmly so that they are packed in well.
Water the plant until the water runs from the bottom of the pot.
Place the pot in an area that gets lots of sunshine and keep the soil moist but not soggy.
Fertilize the ivy and geranium for the first time three months after planting with a 20-20-20 fertilizer, diluted to half the strength recommended on the package. Fertilize the plant every month during spring and summer.
Trim back the ivy with a pair of pruning shears or sharp scissors if it becomes too leggy or aggressive. This will not harm the plant.
