I have dense clay yard soil with rocks so I may need to get ALOT of mulch to grow potatoes in zone 9b. Right? I'm a total beginner so any tips or feedback for zone 9b would be appreciated

I like the idea from the gardener in Australia. G'Day to you. I also have soil like you with clay and rock so digging the trench allows a quick easy replacement but drainage can be a problem with the rocky clay soil. Potatoes love water but too much and they will rot. Try choosing a location with a higher elevation if possible. Sometimes rain pooling can be avoided at higher locations by digging a small trench as a drain. Avoid areas that are already wet or are typically wet. At my place the trench filled with water and took more that a week to drain. I back filled the trench and chose another location.

You could try digging a shallow trench, put the seed potatoes in this, and cover with straw/mulch and compost or rotted manure. Keep topping up the straw as the potatoes grow. You'll end up with potatoes and some good quality soil.

Could you please use US measurements (inches/feet) instead of metric? Gardenate reply: Each plant page has (Show °F/in) about two lines down from the top to change between metric/non metric

We're looking for red seed potatoes to grow in SoCal.

How much sun do potatoes need.. Can they be planted in the morning shade and evening sun
06 Feb 20, Anon (Australia - arid climate)
Most plants need about 5 + hrs. Look it up on the internet, google it.

Can I have a 2nd planting of seed potatoes in very late/early July in containers?

Are you looking for SWEET potatoes or regular potatoes ..... I think your climate is better suited for Sweet potatoes -- they are different (different families) and therefore have different instructions: The ideal soil temperature range for planting potatoes is 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). After planting, the ideal temperature for growing potatoes is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Potatoes do best in fertile, well-drained soils. However, potatoes will grow in many types of soils. Soils that are poorly drained tend to produce poorly shaped potatoes and tuber rot. Potatoes do well across a wide range of pH, but prefer slightly acidic soils; a soil pH of 5.3 to 6.0 is typical for potato production. If your soil is more acidic than this, mixing in wood ash will help raise the pH and make your soil more alkaline. Sweet potatoes (Ipomoea batatas) are close cousins of morning glory and only distantly related to traditional potatoes. They are tender, so must be protected from frost, and like heat, full sun and regular watering. They crop best at temperatures of 21–26°C (70–80°F) PLEASE CLARIFY which type of potato.
