I like to make the most of my garden space. No matter how big the garden is, I never seem to have enough. 

I also enjoy having fresh salad greens all year, but lettuce has a tendency to bolt in our dry, warm summers.

I tackle both problems, and keep weeds at bay with companion planting. 

I plant most of my peas along the fence surrounding the vegetable garden, using the fence as a trellis for the tall varieties. The bed I prepare for them is 50 cm wide, and since I want them to climb the fence, the peas sit at one edge of the bed, leaving plenty of room for weeds to grow.

Instead of letting the weeds take over, I plant my lettuces and spinach in front of the peas. These low-growing plants quickly cover the soil, smothering weeds and naturally mulching the soil, protecting it from the drying sun. The taller peas provide shade to the salad greens for much of the day, preventing them from getting too hot and bolting early.

Both peas and lettuces finish around the same time mid-summer, so it’s easy to pull them all out at once and chop them up in place to thickly mulch the garden edge, preventing weeds from taking over.

And if I’m really thinking, I plant big rangy late crops in the beds nearby—pumpkins, cucumbers, melons or potatoes. They creep across the path and take over the space vacated by the peas and lettuce, making sure the garden space is used continuously all summer.
