Gardening Tips
- Choose plants that are well-suited for your hardiness zone.
- Pay attention to local climate conditions, including rainfall and temperature fluctuations.
- Utilize mulch to retain moisture and regulate soil temperature.
- Consider planting native species, which are adapted to local conditions and require less maintenance.
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 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.
