Do potatoes like morning or afternoon sun?

Potatoes prefer full sun (6+ hours) for strong foliage, but in very hot climates, the intense afternoon sun can stress them, making morning sun with afternoon shade ideal for cooler soil and preventing tuber greening. The key is consistent light for the leaves, while keeping the developing tubers underground dark and cool. Morning sun is great, but if your afternoons are scorching, afternoon shade is a big benefit.

What is the 70 30 rule in gardening?

The 70/30 planting rule is a versatile guideline with two main interpretations: one focusing on native vs. non-native plants for ecological balance (70% natives, 30% non-invasive ornamentals), popularized by Dr. Doug Tallamy, and another focusing on safe, reliable plants (70%) vs. experimental, seasonal plants (30%) for design stability and fun, often used in cottage gardens. Both methods aim for a balanced, successful garden that is beautiful, functional, and manageable, supporting local wildlife or creating visual interest.
 

Does through a window count as direct sunlight?

Sunlight through a window is often called bright, indirect light because glass filters some UV rays and diffuses the intensity, but if the sunbeam hits an object (like a plant) directly, it acts like direct sunlight and can cause burns, making it "direct" for plants that need less intense light, while areas away from the beam are truly indirect. It's considered direct for photography but generally less intense than outdoor sun, depending on window direction (south/west are strongest) and glass type.
 

What is the most common mistake of first time gardeners?

Apply some N at planting for early plant growth. Then, apply most of the N in split applications beginning slightly before (by 10 days) the optimum uptake period.
