About Honeyberry

Lonicera caerulea var. kamtschatica · also called honeyberry, haskap berry · edible

Honeyberry (Lonicera caerulea var. kamtschatica), also called haskap, is an extremely cold-hardy deciduous shrub bearing elongated blue berries that ripen before strawberries. It is not self-fertile, so plant two compatible varieties for cross-pollination. Easy and trouble-free, it crops in sun to part shade and tolerates a wide range of soils.

Preferred mix: Moist, well-drained, fertile soil; very adaptable

Why honeyberry needs this mix

Honeyberry is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.

For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons honeyberry struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Under-feeding and inconsistent moisture. Honeyberry needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.

pH — does it matter for honeyberry?

Honeyberry does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

For containers a good multipurpose or vegetable compost works for honeyberry with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.

Drainage and the pot

Rich but free-draining is the target: raised beds and large containers both deliver it. Mulch heavily to even out moisture and roughly halve how often you water.

Honeyberry is usually grown for a single season, so "repotting" means starting fresh each year — never reuse exhausted, disease-prone compost for the same crop family. When the time comes, our repotting guide for honeyberry covers the timing and technique step by step.

Can I use normal potting soil for honeyberry?

A poor, thin or sandy mix starves honeyberry — growth stalls, leaves pale, and yields collapse.
