Pruning Raspberries
|
|||||||||||||||||||||||
| Ohio State University Extension received a few phone calls about pruning raspberry plants. Gary Gao, Extension Specialist, noted that raspberry plants should should be pruned in March. However, pruning too late is better than not pruning at all. It is critical to find out which type(s) of raspberries gardeners have. Raspberries can be red (summer or fall), purple, black, and gold or yellow. It is very important to understand the terms used to describe various parts of a raspberry plant before attempting to prune raspberries. Raspberry canes are of two types, primocanes and floricanes. Primocanes are first year canes while floricanes are second-year fruiting canes. Refer to OSUE FactSheet HYG-1421-98, "Raspberries for the Backyard Fruit Planting," for additional information. |

| http://ohioline.osu.edu/hyg-fact/1000/1421.html Summer red raspberries should be pruned twice a year, first in the spring and immediately after harvest. The spring pruning, in late March or early April, consists of removing all weak canes and cutting back tall canes (over 5') to 4.5-5'. The second pruning consists of the removal of canes that produced fruits, right after harvest. |

| Everbearing red raspberries such as "Heritage" raspberry can be pruned to produce fruit once a year or twice a year. If gardeners follow the pruning methods used for summer red raspberries, "Heritage" raspberry will produce fruit once in early summer and once in fall. However, many home gardeners and commercial growers mow or cut all "Heritage" canes to the ground in early spring (March or April) for the sake of simplicity. "Heritage" raspberry pruned this way will produce only one crop starting in early August in southern Ohio, and mid-August in central Ohio. It is too late to use the "mowing" method now (early May). However, gardeners can still remove the floricanes that fruited last year. They can also thin floricanes to 6" between canes, if there are too many canes. All canes should be in a strip of 18-24". Those canes that grow outside the 18-24" strip can be removed now. |

Black and purple raspberries are pruned three times a year: in the spring, summer, and after fruiting. First pruning is done in spring when lateral branches are cut back to 8-10" in length in mid-March. Long laterals can still be cut back now, though very late, to reduce competition among the berries so that the remaining berries will get bigger and sweeter. Second pruning is called tipping or heading of new canes or primocanes. When grown without supports, summer tipping is done when black raspberry canes reach 24" in height and when purple types reach 30". Tipping is done by removing the top 2-3" of new shoots as they develop. Third pruning involves the removal of canes that produced fruits, right after the harvest. |
