|'Newberg' bears large, pale red fruits late in the season. It is a hardy cultivar that can tolerant of clayey soil. Raspberries are biennials that perform best in full sun with plenty of water and a good fertilizing when blooms begin.
They are generally thorny, although some cultivars are thornless. A slow warming spring, such as in the Pacific Northwest, is required for optimal flower and fruit production. Staking is also usually necessary.
White flowers are borne from April to June, depending on the cultivar, followed by the much anticipated red or sometimes yellow fruit in late summer. Birds also love the fruit, so you may have to share the harvest.
Plants should be placed 3' apart in rows between 7-9' apart. Fruit is produced on one year old wood. For best results, cut down all fruited canes to ground level at the end of the season.
The Rubus genus is also made up of flowering, ornamental shrubs, either evergreen or deciduous, some of which are native species.
