Branching Out
Deeply Rooted
In our area spinach grow well if planted in very early spring (6-8 weeks before the last frost) or else mid-August through September. From my notes on how to grow spinach: There are two conditions required for spinach to flower: first, they need to have 13 days of growth, and second they need to experience a 12 hour long day. So if they have been growing for a couple of weeks, once they have been exposed to one 12-hour day their flowering hormone will be triggered, and nothing that you can do will stop them from flowering. Some new varieties are ‘slow to bolt’, but be aware of the 12-hour long days from mid-April to mid-September—and don’t put energy into growing spinach in June or July. The trick is to sow a lot of spinach beginning late August, sowing it wherever space becomes available in the garden; you want to grow it quick and harvest it quick. If you are able to, plant spinach where legumes grew before; they will respond well to the extra nitrogen in the soil. Note: my last spinach planting from the autumn is finally ready to pick now; we had some with our dinner last night (planted in a container, under the overhang of the house). The earlier plantings from August were harvested back in the fall, and will send up a second flush of leaves when the weather warms in a few months.Yes. A TEG gardener once pointed out that a good amount of spinach seed grown in the US comes from the Columbia Basin, responding to me complaining that spinach is difficult for me to grow. I responded that this is why it is difficult for me - it bolts to seed.
Early September must normally have the driest weeks of our year. From wheat to chickpeas to canola, that climate feature is very important for seed harvest.

To germinate the seeds I soak them for no more than about 6 hours, drain them, and then place them in a bowl on the kitchen counter overnight with a plate on top to exclude light. It sounds crazy, but most of them start sprouting within 24 hours-- so you have to have a spot in mind for where they are going to go. In the past I have soaked way too many seeds; they really swell up, and end up being more than expected. The variety that I like is called Seaside, and it grows well in the Pacific Northwest.
