You stood there looking at a seed packet in the garden center. Not sure what to buy? That’s a plant that will turn out bitter, or this one turns into something crunchy you’d put on a salad.
It all depends on when it gets sown, how far apart it’s spaced, and how long you can wait for it to show up. It’s not magic; it’s horticulture.
How to Grow Fresh Greens
As an example, here’s a planting chart for 12 types of cool-season greens (above). You can see there’s no “one size fits all” approach: Arugula, for instance, gets sown, sprouts quickly, and is edible in under a month. Collards, on the other hand, don’t really mature until more than two months after planting, and then take up a lot of room. Knowing that makes a difference; it guides you when planning where things go in the garden. Planting them all together results in too many arugula and puny collard green, right? That’s why we successions-sow (we sow a little bit every ten days), so we’re always eating something fresh.
Beginners trip on the fact that greens is largely water. That’s why they’re lightweight! By weight, spinach is almost 90 percent water; kale is more dense. Texture varies, which affects how they are stored and cooked.
Remember: Keep the soil consistently moist, but not sodden. For most varieties, that means an inch or so weekly. If the soil dries right out, those leaves will become tough. Soggy? You’ve invited in rot. It is a fine line, but harvest feels rewarding.
Heat is not your friend: When things get hot, lettuce bolts rapidly. Spinach does too. Send up that awful-tasting flower stalk. And then? Cover with shade cloth when temps exceed seventy-five degrees, advises the guide. It’s another thing to do, yes, but adds weeks of slow-growing but tender summer greens to your menu. Fight the sun at your peril. It makes the plants feel the heat, and they’ll panic. You want them happy and relaxed.
These crops differ than cold tolerance, too. Here’s where frost bands come in. Some (kale and collards) were made for winter. They can takes some serious cold, even when temperatures is in the teens. Others (like romaine) wilt when it turns heavy; so time your plantings accordingly. Sow hardy brassicas like kale and collards early fall for a winter crop. Reserve tender lettuces for the relatively mild days of late summer and spring.
There is another benefit to rotating between types of greens. Nutrition: In terms of Vitamin K, Swiss chard tops the list and kale isn’t far behind. For calcium, again kale take first prize. Spinach packs a lot of beta-carotene, which then gets converted by your body to vitamin A. By combining these in your salad bowl, you’re able to cover all your mineral bases. It’s not just delicious, it’s about creating a well-fueled body.
Thin your seedlings early, early, early. This is the biggest no-no: letting your young greens get crowded. Why? To grow good stems, they require air and light. Even when you think you’re pulling up perfectly healthy plants, do it within a couple of weeks of germination. Yes, it stings. But the survivors will be happy campers. Those that go bye-bye becomes next week’s salad.
Start small now and take consistent action later. Harvesting a leaf that you grew from seed, watching it grow… Is rewarding. You put in the work to get it; it taste good for it. Be sure to keep watering regularly and also ensure the soil stays cool. Patience is very important. Fresh, crisp greens will reward you back in the garden.
