More than any other common crop, spinach doesn't like warm weather. It actually germinates best at only 50 degrees F. It germinates more rapidly at higher temperatures, but at 70 degrees F only about half the seeds will germinate.
Spinach bolts when exposed to long summer days, so it is usually grown as a spring or autumn crop. It's much less prone to bolting in the shorter, cooler days and the leaves grow larger and more succulent.
Each plant doesn't produce very much, so it is usually grown in wide intensive beds. Raised beds are good because they warm up quickly in spring and tend to be well drained.

Spinach needs full sun for good growth, particularly for a fall or over-wintering crop.
Spinach doesn’t like heat and in warmer areas it should be planted in a shady site.
Keep the soil evenly moist (not wet) otherwise it may bolt. Fortunately this isn't usually a problem in the cool weather preferred by spinach.
Try to avoid splashing mud on the leaves as it can make them gritty.
Spinach needs a moderate amount of nitrogen and potassium and a fairly small amount of phosphorous.
- Tolerates light frost, Needs summer shade
- Small Gardens?
Spinach can work well in containers, though they need to be sufficiently large (ideally a two gallon pot for each plant). In larger containers allow 12" between the plants for best growth.
In warmer areas you should use light colored pots to reduce heat absorption.
