Let me offer a little piece of advice: if your spinach looks like this, don’t eat it! Spinach likes its days short, its soil moist, and its temperatures cool. So, at this time of year when our days are long, and warm, and dry, spinach tends to go to seed, or bolt as the process is sometimes called. This is bad news for you because bolted spinach tastes very bitter and develops a tough, unpleasant texture. Trust me on this. I took a little nibble of my bolted spinach this morning, and let’s just say I did not pick more leaves for breakfast.
The development of pointy, arrow shaped leaves is the first sign that your spinach will soon bolt. As soon as you see the merest hint of a pointy leaf, harvest all your spinach before it has a chance to turn bitter on you. If, like me, you weren’t paying attention and your spinach shot skyward before you noticed, it’s best to just pull the plants and throw them on your compost pile because the leaves are inedible at this point.
I’m going to take out my bolted spinach today and sow dino kale in its place. Beets or Swiss chard would be a good bet, too, becuase they grow quickly and stay tender and tasty even in the heat.
