The Hardy Orange can grow in a wide variety of conditions. They tolerate heat & drought well, & are not picky about soil type. They are able to grow in heavy clay soils, sandy soil, & nutritionally poor soil ranging from very alkaline to acidic. Part shade is perfectly acceptable for growing these, although the plants will produce more fruit in full sun. Hardy Orange shrubs have thorns, making them deer & rabbit resistant, & also a great choice for a ‘security’ type hedgerow. Of course one of the main thrillers is the extreme cold tolerance of this bad boy! The Hardy Orange is commonly uséd as rootstock for other citrus plants to help increase their cold hardiness. I will caution you though, the plants are ‘borderline’ hardy in Zone 5. If you are in Zone 5, you will want to protect your shrubs with some extra mulch for the winter & grow them in a sheltered location if possible.
