Considerations for Plant Selection
- Climate Variability: Understand the seasonal temperature fluctuations and rainfall 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 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.

Irrigation Tips
Water management is important . Using a simple oscillating sprinkler in the early morning ensures water reaches the roots without evaporating too quickly. This method is great for home gardens. One option toconsider is the Eden Oscillating Sprinkler, priced at $17.94. It features 6 precision nozzles, a leak-proof connector, and a quick-connect mechanism to easily attach it to your garden hose.
