Considerations for Growing Spinach

The biggest problem you will most likely experience when growing spinach is having it bolt, or go to seed, without producing many leaves. This can be avoided by growing spinach early in spring or later in the fall once the weather has cooled.

To discourage bolting in the heat of mid summer, I plant my spinach in a partially shaded location. Last year I chose a place in my garden on the north side of my peas. The peas growing up the pea fence provided shade for the spinach, keeping the ground cool.

Once spinach begins to form seed heads it will continue to put most of its energy into growing seeds and there will be little to no more growth of the spinach leaves. For this reason, once you observe seed heads forming, it is best to harvest all the usable leaves and to re-plant your next crop of spinach, or something new in that location.

When to Plant Spinach

Sow spinach seeds directly into your garden in early spring as soon as your soil is workable. For me, growing spinach in Alberta, I seed my first crop around the end of April. Follow with subsequent plantings every two weeks to maintain a constant supply. Spinach can withstand temperatures as low as -8C (18F). Don't worry if you end up with snow on top of your growing spinach, it will most likely not mind at all.

Spinach seeds that are slow to bolt in summer heat are great for growing spinach in gardening zone 3 Alberta during the summer months.
