It should be fine. Shrubs will wilt if they're planted right next to a house or cliff, or the edge of the river.They also wilt if you have more than 12 touching eachother.
They will grow as long as there arent more than twelve in a row, and they aren't directly by a building or cliff, like thegreatbrain said. Seeing as you already grew shrubs in that location and you're just replacing them, you should be fine.
