Fruit crates are just tall enough to accomodate leafy greens or herbs with shallow root systems. I decided to fill this one up with a crop of mache. Mache is the de rigour green of the uppercrust and a good choice if growing lettuce feels like a waste of time and space. The succulent leaves make a delicious salad (especially good with figs and blue cheese) but fetches a hefty sum at your typical Whole Foods.
Little work is required to prep your crate for growing. The bottom of mine had large spaces between slats and required some kind of coverage to hold soil in. Alternatively, crates with solid bottoms will require drainage holes to let water out. I laid an average-sized plastic shopping bag inside the crate and cut a bunch of small holes with a pair of scissors to make drainage. The key here is making a vessel that will hold soil, but adding drainage back so your seedlings aren’t swimming during a heavy rainfall.
Next, I filled up the crate with good quality container soil. A cheap container plus cheap soil, equals too much cheap! When it comes to container soil you get what you pay for. Your best bet is usually with the mid-ranged priced soils. Avoid the Miracle Grow stuff if you can. Fill your container to the top and tamp it in with your hands. You want to remove the air pockets and make a respectably flat surface. Don’t go crazy with it — a level is not required.
Once you’ve got your soil in place, cut around the edges with the scissors to remove the excess plastic bag. Pour a handful of seed into your hand and spread it thinly, and evenly across the soil surface. Don’t worry if you have too many seeds as you can remove excess plants later. Add another 1/4″ of soil on top of the seeds and water everything in well.
Leafy greens prefer cool weather and shadier spots. Plants will bolt in hot weather which means that they quickly go to seed and become bitter. How much sun is too much depends on your conditions and the time of year. Mine are currently placed in a sunny spot on my rooftop deck because the daytime temperatures are in the light sweater to spring jacket plus long sleeve shirt range. I will move it to a shady spot when the heat picks up. Water your container everyday. Soon you will see little tiny plants emerging. Here are what mine looked like today 15 days after sowing. Mache can take as much as 20 days to emerge from below the soil so don’t give up if yours take their sweet time. Be patient!
Other suggestions for your crate:
- Rouge d’hiver lettuce
- Red orach
- Kale (grown as baby kale only)
- Thyme – lemon, lavender, orange, silver…
