My holly bushes are bare in the middle and only have leaves and berries near the ends. How can I improve them?

If the shrub has leggy growth like this, it usuallly indicates that the shrub is in need of some pruning. Hollies, as with most shrubs, can be pruned back by a third of their growth. Any more than that will likely harm the plants. This article should help: https://www.gardeningknowhow.com/ornamental/shrubs/holly/trimming-holly-bushes-how-to-prune-holly-bushes.htm
