Plum
An early orchard tree flowering in March and April, when cold weather regularly keeps honey bees inside and mason bees and mining bees carry the crop. Its blossom is a genuinely useful early forage source in a way that pear's is not, and it produces a modest surplus in orchard districts.
Value to bees
- Nectar
- Moderate
- Pollen
- High
- As a honey crop
- Minor honey crop — a surplus only locally or occasionally
- Which bees, and why
- Flowering in March means honey bees are frequently grounded by cold, and mason bees and mining bees — which fly at lower temperatures — do a disproportionate share of the pollination. Bumblebee queens work it heavily in the same window.
- Worth knowing
- A useful early nectar source and a generous pollen source when colonies most need pollen for brood rearing.
Flowering
- In flower
- March to April (northern hemisphere)
Very early — often the first orchard fruit in flower, and correspondingly frost-vulnerable.
- When nectar flows
- Reasonable and early, and useful mainly for building colonies rather than for surplus.
- Year-to-year variation
- A minor crop. Plum blossom honey is rarely separated and mostly contributes to early mixed honey in orchard districts.
Growing it
- Conditions
- Full sun, shelter from spring frost, and moisture-retentive soil. Frost during bloom is the commonest cause of crop failure.
- Size
- 3-8 m depending on rootstock.
- Native range
- A hybrid of Eurasian origin, cultivated for millennia across Europe and western Asia.
- Suits
- Small gardens, Orchard, Large gardens
- Many cultivars are self-fertile, so a single tree can crop — which makes plum a good choice for a small garden.
- Very early flowering means frost risk; avoid frost pockets and low-lying sites.
- Prune only in summer, never in winter, to avoid silver leaf disease.
What it looks like
A small spreading tree with oval leaves and clusters of white five-petalled flowers opening before the leaves, giving the bare branches a solid white outline.
