Considerations for Plant Selection
- Climate Variability: Understand the seasonal temperature fluctuations and snowfall patterns in your area.
- Sun Exposure: Assess the amount of sunlight your garden receives throughout the day, as this affects plant growth.
- Water Availability: Evaluate your irrigation options and the water needs of your chosen plants.
- Soil Quality: Conduct soil tests to determine pH levels and nutrient content, ensuring a suitable environment for your plants.
The Importance of Good Soil
Before starting to grow, it’s essential to assess the condition of the soil in your garden. The best soil is a blend of mineral-rich dirt and organic matter. In my garden, I compost as much as possible to enrich the soil with nutrients. I use both hot composting for food scraps and cold composting for organic garden waste.
If you don’t have the time or space to compost, you can purchase compost from Amazon, local garden centers or use community composting programs. Learn more about community composting here: Learn more about community composting here.
Where I live I get a large tax refund every year for composting may own organic waste. Due to this saving I was able to break even on the cost at only two year use. I recommend you to check with your local government if you can receive any tax refund.

Greenhouse Growing
Imagine extending your growing season and harvest fresh plants into the cold season.
When the growing seasons are short and weather can be unpredictable, utilizing a greenhouse allows for a controlled environment. This promotes better growth , protects plants from harsh weather, and can enable earlier planting. Greenhouses also maximizes the growing season.

Greenhouse benefits
- Extended growing season: A greenhouse allows for an earlier start in spring and extended harvests in fall.
- Protection from harsh weather: It shields plants from extreme cold, wind, and frost.
- Improved plant health: Greenhouses maintain stable temperatures and humidity levels, reducing stress on plants.
- Increased variety of plants: You can grow a wider range of plants, including tender ones that would not survive outside.
Using Mulch
Mulch protects the soil by regulating temperature and retaining moisture. Organic mulch like straw or compost insulates the soil and keeps roots warmer, which is especially important in spring and fall.
Mulch also helps retain moisture by reducing evaporation, which means less time watering and less stress on plants. It is especially helpful in raised beds and containers where soil dries out faster. Additionally, mulch controls weeds, stopping them from competing with your vegetables for nutrients.
The Sun Joe CJ603E Wood Chipper is an affordable and effective option for creating mulch from branches up to 1.7 inches thick. It’s available for $199. Check the latest price on Amazon.
xtra Care During Colder Months
As winter approaches, many plants in Vermont require additional care to survive the harsh conditions. Techniques such as mulching, using row covers, and creating cold frames can help protect sensitive plants from frost and extreme temperatures. These practices not only insulate the plants but also retain soil moisture and prevent weed growth.
Soil Type and pH Levels
Understanding your soil type and pH levels is crucial for successful gardening in Vermont. Conducting a soil test can reveal nutrient deficiencies and help you amend the soil accordingly. For example, some plants thrive in acidic soils, while others prefer alkaline conditions. By knowing your soil’s composition, you can make informed decisions about plant selection and amendments.
