17:25 Conclusion and Farewell

HERE ARE THE 3 KEY TAKEAWAYS FROM THIS EPISODE:

1️⃣ If you want to get professional results, you need to use professional supplies and techniques.

2️⃣ When selecting gardening tools, it's important to take into consideration our region. For example, our soils are naturally deficient in nitrogen, so the best fertilizers for us are high in nitrogen compared to phosphorus and potassium.

3️⃣ Sun protection supplies ARE gardening tools! We usually think about apply sunscreen when we're headed to the beach or pool, but applying sunscreen is an important pre-gardening ritual as well.
