Planting guidelines
- Understand the specific climate and soil conditions in your area to choose the right plants.
- Implement efficient irrigation systems, such as drip irrigation, to conserve water.
- Use organic mulch to retain moisture, suppress weeds, and improve soil quality.
- Incorporate native species into your garden to promote biodiversity and reduce water usage.
- Plan your planting schedule according to seasonal changes and local frost dates.
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.

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.
