Answer: Oleanders are quite adaptable to soil types; their only requirement is soil that drains quickly. You shouldn't need to amend your soil unless it is hard clay and simply will not drain. If you do have clayey soil, mix organic matter into the planting bed and then plant your oleanders. If you have average garden soil, you won't need to add anything to it. Don't fertilize your new plants when planting; wait until next spring to feed them. Just plant them at the same soil level as they were growing in the nursery pots and water them deeply once or twice a week (depending upon weather). The roots will establish within a month or two and you should see new growth. Enjoy your new plants!
