Glen Ample

A summer raspberry: it fruits on canes grown the previous year, so those canes are cut out after picking and this year's growth is tied in for next year. Spine-free, heavy cropping and the usual first recommendation.

A cultivar of Raspberry. Everything on this page is about the cultivar; how to grow the species is on the plant page, and how big the tree gets is on the rootstock page.

Partners for Glen Ample, from the 4 raspberry cultivars GrowingHQ holds

Computed by the pollination engine from the flowering groups, ploidy and recorded pairings on each record — not a hand-written list. The scope is exactly what the heading says: these are the answers that exist in this catalogue, not the answers that exist.

No partner is required

Glen Ample sets a crop on its own pollen. The table below is still computed, because a compatible neighbour does no harm and a grower planting two trees may want to know which pairs work.

No compatible partner in this catalogue

That is a statement about GrowingHQ’s coverage rather than about the cultivar. A nursery list will contain compatible cultivars this catalogue does not hold — the pollination mechanisms page explains how to work one out.

3 further cultivars return no verdict, because a flowering group or an incompatibility group is not recorded on one side. The engine reports that rather than assuming a value: Autumn Bliss, Malling Jewel, Polka.

Why that decides the pruning

Fruit forms on stems produced the previous season, which then decline. Pruning removes the oldest wood at the base each year to force new stems.

What it is prone to

Cultivar behaviour, not a diagnosis. Every level here is relative to other cultivars of the same species.
