🌱 How to Grow
From Seeds:
-
Sow Indoors: Start 6–8 weeks before last frost in deep pots.
-
Plant ½ inch deep in moist seed compost.
-
Transplant when seedlings are strong and frost risk has passed.
-
Be Patient: Allow at least one full season for root development before harvesting.
From Crowns (Preferred Method):
-
Plant dormant crowns in early spring or autumn.
-
Position with buds just below soil level in fertile, well-drained soil.
💧 Care Tips
-
Watering: Keep soil moist, especially in dry weather and during the growing season.
-
Feeding: Mulch annually with well-rotted manure or compost.
-
Pruning: Remove flower stalks as they appear to direct energy into stems.
-
Divide every 5–6 years to rejuvenate growth.
🌼 Growing Sustainably
-
Low Maintenance: Once established, rhubarb requires little effort.
-
Cold-Loving: Thrives in UK climates with frost needed for dormancy.
-
Natural Pest Resistance: Few problems once mature — great for organic growing.
✂️ Harvesting
-
Start in Year 2: Never harvest in the first season to allow roots to strengthen.
-
Pick from April–June: Twist and pull stalks at the base (don’t cut).
-
Leave Some Stalks: Always leave a few to keep the plant healthy.
Tip: Only stalks are edible — leaves are toxic and should be composted or discarded safely.
❄️ Overwintering
-
Fully hardy — rhubarb dies back in winter and returns each spring.
-
Mulch in autumn to protect crowns and enrich soil.
