A flowering calendar is one of the most useful reference tools a new beekeeper or gardener can have, because understanding the “forage gap” (times of year when food is scarce) is critical for colony survival. Here is a chronological list of the most important native and common plants, trees, and shrubs that our bees rely on, It shows whether the plant provides primarily nectar (carbohydrates for honey), pollen (protein for brood rearing), or both.

Beekeeper’s Note: A Quick Warning for Hive Keepers: Ivy Granulation

Common ivy (Hedera helix) is a vital autumn lifeline, delivering rich pollen to build strong “winter bees” and fuelling bumblebee queens before hibernation. However, ivy nectar has a very high glucose content and crystallises rock-hard in the comb within days. In prolonged winter freezes, bees can struggle to dissolve these hard crystals without flying for water. If you keep hives near established patches of ivy, balance their winter stores with early autumn 2:1 sugar syrup or fondant so the cluster always has accessible, soft feed right through January and February.

During your routine hive inspections, monitoring incoming pollen colours is a fantastic way to verify which local forage your bees are working.

Start Your Own Pollinator Patch

If you want to help fill in the “forage gaps” in your own garden, the easiest way to start is by planting hardy, nectar-rich varieties that require very little maintenance. You don’t need a massive fieldβ€”even a few large pots or a dedicated border can make a huge difference to local colonies.

Here are three of the easiest wins for a beginner gardener:

  • Early Spring Lifelines: Planting Crocus bulbs in the autumn guarantees that waking bees will have a vital source of fresh pollen in February and March, right when the colony needs protein the most.
  • The Summer Staple: Scattering Borage seeds provides a massive summer nectar flow. Borage thrives in poor soil, and its flowers actually refill with nectar incredibly fast after a bee visits.
  • The Lazy Meadow Hack: If you have a bare patch of soil and want a mix of native blooms without the fuss of planning, tossing down a few UK Wildflower Seed Bombs is brilliant. You literally just throw them on the dirt, let the rain break down the protective clay, and watch them grow.
