Winter-Proofing Your Greenhouse for Optimal Plant Protection
Insulating your greenhouse during the winter is absolutely vital for protecting your plants from frigid temperatures and damaging drafts. Proper insulation regulates the environment inside, preventing precious specimens from freezing or dying off when cold weather strikes.
Why Insulating a Greenhouse is Crucial for Winter
During the colder months, the interior of an uninsulated greenhouse can drop to near-freezing temperatures at night. This puts tender plants at high risk of damage, stunting their growth or even killing them outright. Insulation acts as a barrier to block cold outside air from entering and warm air inside from escaping. It helps maintain a stable, moderate temperature range ideal for overwintering plants. As gardening experts Carole Baxter and Scott Smith demonstrate in this winter’s episode of Beechgrove Garden, a well-insulated greenhouse allows you to safely grow plants that would perish outdoors in your winter garden.
A Step-by-Step Guide to Insulating Your Greenhouse
Insulating a greenhouse is a straightforward process that anyone can tackle in a weekend. Follow these key steps recommended by the pros:
- Inspect your greenhouse for drafts and gaps around doors, vents, and glazing. Seal any cracks with caulk or weatherstripping to reduce air leaks.
- Install insulation panels, such as polystyrene sheets, on the interior walls and roof. Secure them in place with battens. For added effectiveness, use horticultural fleece over the insulation.
- Add a layer of insulating bubble wrap to greenhouse doors and windows. This second barrier further prevents warm air from escaping.
- Consider lining the floor with polystyrene sheets or using special thermal ground cover blankets. This protects plant roots from the cold ground.
- Install a propane or electric heater optimized for greenhouse use if extremely cold temperatures are expected. Maintain the interior above 45°F/7°C.
Cost-Effective Insulation Materials
The good news is that insulating a hobby greenhouse need not be expensive. Here are budget-friendly options to consider:
- Recycled polystyrene sheets – Sturdy and effective; can often be found for free.
- Cardboard panels – Readily available and easy to install.
- Straw bales – Provide great insulation and can be reused as mulch later.
- Bubble wrap – Versatile and adaptable for covering gaps.
- Old blankets/comforters – Repurpose what you already have at home.
With the right preparation, your greenhouse can continue nurturing plants through the coldest months. Proper insulation allows overwintering of specimens that would perish outdoors.
Evergreen Shrubs and Trees: Creating Year-Round Interest in Your Garden
Gardens often look bleak and barren during the winter months, especially after flowering plants and deciduous trees lose their greenery. An excellent solution for adding beauty and interest during this fallow period is to incorporate evergreen plants into your landscape design. As Carole Baxter discusses in this episode, evergreen shrubs and trees maintain their leaves or needles all year long, providing color when other plants are dormant.
Why Evergreen Shrubs and Trees are Ideal for Winter
While most trees and shrubs drop their leaves in autumn, evergreens keep their foliage intact throughout winter. This persistent greenery offers myriad benefits:
- They provide year-round screening and privacy for your garden.
- Their presence adds color and texture when deciduous plants are leafless sticks.
- Evergreen foliage and needles catch and hold winter snow for striking effects.
- Varieties with colorful winter berries give pops of visual interest.

Demystifying the Magic of Autumn’s Changing Leaves
One of the most dazzling natural spectacles of the year unfurls across the landscapes of North America every autumn. As Scott Smith explains in this episode, the annual transformation of green summer leaves into vivid hues of red, orange, yellow and purple is scientifically fascinating. Understanding the biology behind this colorful display allows you to fully appreciate the magic.
Why Leaves Change Color in Fall
While the shifting length of days and cooling temperatures trigger the process, leaves changing from green to other shades is the result of intricate chemical changes within the leaf:
- Chlorophyll, the pigment that makes leaves green, starts to break down as days grow shorter in fall.
- Vibrant carotenoids like xanthophylls and carotenes, present all along, are revealed when chlorophyll fades. These create yellow and orange shades.
- Red and purple anthocyanins form in some species as sunlight and sugars concentrate in the leaves.
- Abscission cells grow, cutting off water and nutrients to the leaf and eventually causing it to detach from the branch.
- The precise combination of pigments left behind determines the final colorful display.
How Weather Impacts Autumn Foliage Displays
Weather conditions leading up to and during fall have a significant impact on the intensity of leaf colors that develop:
- Cool nights and bright, sunny days increase anthocyanin production, boosting reds. Cloudy periods result in more muted tones.
- Warm, wet weather can cause leaves to fade and brown before achieving peak color.
- Drought stress also diminishes the brilliance of the annual show by causing leaves to drop early.
- Freezing temperatures destroy tender leaves before they change fully. However, a light frost intensifies existing pigments.
- Very wet or windy conditions can quickly strip trees of their colored leaves at peak maturity.
Supporting A Spectacular Display in Your Yard
You can enhance the fall foliage extravaganza in your own yard by:
- Planting native deciduous trees and shrubs that are renowned for their fall color like maples, oaks, tupelos and sumacs.
- Providing adequate moisture before and during the color change period to avoid drought stress.
- Mulching around trees to maintain soil moisture and nutrient levels.
- Allowing leaves to accumulate as natural mulch rather than blowing or raking them away.
By understanding the scientific processes behind nature’s fall frenzy of color, you can fully appreciate autumn’s painted landscapes and cultivate an eye-popping leaf show of your own.
Attracting Winter Wildlife to Your Garden with DIY Habitats – Beechgrove Garden in Winter 2023 episode 1
As temperatures drop and natural food sources dwindle, birds, beneficial insects and other wildlife face immense challenges surviving through winter. However, as Kirsty Wilson demonstrates, you can give local fauna a helping hand by creating specialized shelters in your garden. Providing winter habitat helps sustain vulnerable species when they need it most.
Why Local Wildlife Needs Support During Winter
Many birds and insects that enrich our landscapes face scarcity when winter strikes:
- Migrating birds have depleted resources after long journeys and can starve without adequate food and shelter.
- Insects must escape freezing temperatures but have few protected places to overwinter in dormancy.
- Native wildlife competes fiercely for limited natural winter provisions like berries and seeds.
- Essential pollinators like bees may not survive to resume their roles come spring without help.
- Loss of winter refuge also leaves adult wildlife and offspring more vulnerable to predators.
Step-by-Step Guide to Building a Multi-Chamber Bug Hotel
One excellent way to bolster your garden’s winter wildlife is constructing a bug hotel:
Gather Materials
Grab old wood, bamboo, straw, pinecones, leaves, sticks, cardboard and string. Ask neighbors for cast-off materials or check yard waste sites.
Select a Dry, Sheltered Spot
Choose a location protected from wind, rain and direct sun. Near trees, fences or sheds is ideal.
Build the Frame
Use pallets, old wood, sticks or bricks to assemble the exterior frame. Make it at least 12 inches wide and deep.
Add the Chambers
Fill the frame with varied natural materials—rolled up cardboard, straw, dead leaves, sticks, bamboo—to create small chambers and tunnels.
Make a Living Roof
Top the hotel with sod rectangles, moss or branches to provide insulation and camouflage.
Maintain the Hotel
Avoid disturbing the hotel in winter when insects are dormant within. Clean out chambers in spring.
Monitor Guests
Observe bees, beetles, spiders and other beneficial creatures using your hotel for winter refuge.
With a small investment of time and materials, you can create winter sanctuary for precious pollinators. Your DIY bug hotel may make the difference for their fragile populations surviving until spring.
The Science of Changing Leaf Colors: Nature’s Brilliant Biochemistry
As days shorten and temperatures cool, a remarkable transformation occurs in the leaves of many trees and shrubs. Green pigments fade and disappear, revealing vibrant yellows, oranges, reds and purples. This annual fall spectacle results from intricately orchestrated chemical changes within leaf cells. Scott Smith outlines the key biological processes underlying autumn’s painted foliage.
Chlorophyll Breakdown Exposes Hidden Pigments
Chlorophyll, the dominant pigment in leaves, absorbs red and blue light to power photosynthesis. But production of this vital green pigment slows as winter nears. Chlorophyll molecules degrade and colorful carotenoids, previously masked, shine through. These create the vibrant yellows and oranges of fall.
Sugars and Light Drive Anthocyanin Synthesis
The crimson and purple hues result from production of anthocyanin pigments. These form only when sugars are abundant and light levels high, typically in autumn. The precise mixture of anthocyanins determines the final red tone.
Why Some Trees Turn Color and Others Don’t
Several factors influence whether a tree develops fall color. Bright foliage requires chlorophyll to break down, revealing carotenoids. Production of anthocyanins depends on excess sugars and light. Evergreens retain their green year-round thanks to durable chlorophyll that persists through winter.
Weather Conditions Modify Autumn’s Palette
Temperature, sunlight, precipitation and soil moisture in the weeks preceding fall significantly impact the transformation. Warm sunny days and cool nights create ideal conditions. Early frost, drought and heavy rain or wind can cut the show short.
Top Trees for Spectacular Fall Color
Certain tree species are renowned for outstanding displays of vibrant fall foliage. Here are top picks for electrifying color from Carole Baxter:
Sugar Maple
The classic maple of New England and Eastern Canada famed for brilliant orange-red leaves. Other maple species like red and black also shine.
Red Oak
A widely distributed oak famed for its russet-red fall canopy. Pin oak and black oak also develop striking reds.
Sweetgum
This native tree brings amazing color range—yellow, orange, red and purple—sometimes all at once.
Sourwood
A Southeastern native that reliably ignites red-orange each fall. Slow growing but worth the wait.
Persimmon
After sweet orange fruits appear, the oval leaves turn vivid orange-red for a dramatic two-act show.
American Beech
Beech trees hold golden bronze leaves well into winter, providing fall interest for months.
Southern Red Maple
More cold tolerant than sugar maples with similarly brilliant red and orange autumn foliage.
By selecting trees inclined to color transformation, you can brighten your landscape with fall magic each year. Their vivid foliage will electrify any yard or garden.
Support Wildlife in Winter by Providing Food, Water and Shelter
As Kirsty Wilson demonstrates, a bit of planning and effort in your garden can help local wildlife survive the toughest months. You can save lives by providing essential provisions that become scarce when temperatures plummet. Here are tips for supporting birds, pollinators and other creatures through the winter.
