Considerations for Plant Selection

  • Understand the seasonal temperature fluctuations and rainfall patterns in your area.
  • Assess the amount of sunlight your garden receives throughout the day, as this affects plant growth.
  • Evaluate your irrigation options and the water needs of your chosen plants.
  • 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 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.

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.

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.
