Foster Holly is a hybrid of two different hollies and produces berries relatively early compared to most other varieties. There are many reasons why homeowners plant holly in their garden, one of which is the fact that they provide gorgeous garden interest throughout every season. This is particularly important in the fall and winter, when most plants aren't in bloom and a lot of other trees begin to lose their foliage. However, some homeowners are a little wary about planting Foster Holly in their gardens, especially if they have small children or animals, because of the fact that some parts of the plant are poisonous if they are ingested.
Foster Holly grows extremely well in hardiness zones 6 through 9. If you try to grow it in an area outside of this zone, it is likely that keeping your plant healthy will prove to be extremely difficult. It is best to stay within these parameters. Foster Holy is a type of holly that produces berries. These berries appear in mid summer. As with all blooming hollies, you will need to make sure that you have both a male and female plant in order for the female plant to produce berries. As long as their is a male within a mile of the female, you should have no problems with pollination.
Foster Holly is relatively easy to grow, but you have to make sure that the soil around the plant is never allowed to dry out. You must be careful not to overwater, but instead water at least once or twice a week to keep the soil from drying out. If the plant is overwatered, it becomes extremely susceptible to root rot, which will stunt the plant's growth and prevent it from thriving.
