🌿❄️ OVERWINTERING TENDER PLANTS ON A BUDGET! 🌴🌱
It's that time of year again! The temperatures are dropping here in Northern Ireland, and the annual mission to keep as many of my tender plants alive through winter has officially begun! 🥶😂
This year, I'm trying a few different techniques to make overwintering as cost-effective as possible, without relying on expensive heating systems.
🌵 First up, the Aeoniums! I've managed to squeeze as many as possible into cold frames inside my polycarbonate tunnel. Essentially, it's a greenhouse within a greenhouse! The idea is to create an additional layer of insulation, offering some extra protection against frost and those particularly cold winter nights. I'll also have horticultural fleece on standby when temperatures really start to drop!
🌴 And the tunnel is certainly filling up! Alongside the Aeoniums, I'm attempting to overwinter a whole collection of plants, including:
🌿 Colocasia
🌳 Sparrmannia africana
🌵 Mangaves and Agaves
🍌 Musa sikkimensis and Musa basjoo
🌸 Various tender summer bedding plants
🌱 Different varieties of Plectranthus
🌺 Cockscomb coral tree
💛 Yellow bottlebrush shrubs
I'm particularly keen to save as many of my summer bedding plants as possible. Not only does it reduce the cost of buying new plants every spring, but it also means I can keep enjoying some of my favourite summer colour year after year! 🌸
☀️ I'm also trying a little experiment this Winter!
I've laid black, shiny tarpaulin across the tunnel floor to see whether it might absorb some additional warmth during those occasional sunny winter days and release a little of that heat as temperatures fall.
Will it make a noticeable difference? I've absolutely no idea! 😂 But gardening is all about experimenting, learning and occasionally getting things wrong. It's worth a try!
Of course, horticultural fleece will be making plenty of appearances throughout the winter, and I'll be keeping a close eye on temperatures, ventilation and moisture levels.
🌱 The goal? To get as many of these beautiful plants through winter and into spring 2027 without spending a fortune in the process!
I'll keep you updated on what works, what doesn't and which plants make it through. Fingers crossed for a mild Winter! 🤞❄️
Are you overwintering any tender plants this year, or have you any clever tricks for keeping the frost at bay? I'd love to hear them! 👇
