Raspberry root rot

Asked September 2, 2013, 5:30 PM EDT

Can I successfully grow any variety of raspberries in a row previously killed by root rot? Had purchased Cascade Delight (research showed they were root rot resistant) and planted in nearby row. They died on second year after planting....don't know cause. Previous berries had died after 8 years of excellent production.

Sorry to hear of Cascade Delight coming down with root rot so quickly. it is considered to have some tolerance to root rot so the "pressure" in your planting site must be high. I would strongly encourage planting on raised beds if you haven't already. If you have only the one location, then I would choose a root rot resistant variety. The one I would recommend is Cascade Bounty. This variety can be grown successfully on a root rot site.

Thank you for the response. Not sure if the Cascade Delight got root rot (never examined the canes) as they just died and disappeared. Last summer was pregnant and this summer tending to baby so didn't get into garden much. Planted the CD in a raised row (about 6" above ground level) about 4 feet from row that had root rot.
Have read about fungicide that may help and also trying solarization of area. Any experience using either?
Do you know where someone can purchase the Cascade Bounty berries? Are they a western berry?

Thanks again for your response,

Hello Ms. Larson,

Firstly, if it's not too late, I would recommend raised beds higher than 6 inches -- this allows more of the roots to be in better drained soil and stay "ahead" of the root rot. There is nothing registered for this disease for home garden use so raised beds and judicious irrigation and tolerant or resistant varieties are the tools available (cultural controls).

Cascade Bounty (and Cascade Delight) were bred and released at WSU. Unfortunately Bounty was not available this year but is expected to be available next spring. One other resistant variety (developed in NY) is Prelude. You can find it in the mail order nurseries -- e.g. Indiana Berry Company (https://indianaberry.com/) and Nourse Farms (http://www.noursefarms.com/).
