Seasonal tips

  • Clear snow from garden beds gently to prevent ice crusts that can damage emerging buds next spring.
  • Apply a thick layer of mulch over perennial crowns once the soil has fully frozen to protect roots from extreme temperature fluctuations.
  • Now is an ideal time to plan your spring succession schedule and order seeds for early crops like peas or lettuce.
Keep watch

Pest & disease watch

  • Monitor storage areas for rodent activity as they seek shelter in milder spots during cold snaps.
  • Check evergreen shrubs occasionally for winter moth egg masses before pruning next season.
Water

Watering this week

No outdoor watering is necessary while the ground is frozen.

One more thing

Take this quiet time to inspect your greenhouse or cold frame structure for any winter damage that needs repair before the planting rush begins.
