Some of this matchmaker's “blind dates” in the garden just aren't good fits


July 14, 2015
 
I love the surprise and small miracle of windfallen seeds that sprout in unexpected places in my gardens. Even if I have designated another plant for that spot, I'm usually willing to be a matchmaker and hope the two species will live together happily. So when I checked my future tomato bed this spring and found a few volunteer sunflower plants already setting down roots, I only smiled. The sunflowers would grow directly in front of the south-facing, low cement wall and behind the tomato plants. Everybody would get the sunshine and, at worst, the taller sunflowers could block the tomato vines from the harshest heat of high summer. This would be a match made in the Garden Goddess's heaven.

What is wrong with me? I have grown sunflowers for decades – and always buy the seeds that will produce the big honkers – the tall, branching plants with multiple flower heads – so the birds can enjoy healthy autumn snacks. I make sure to plant the sunflowers in the bed directly below my writing room window, so I can watch the finches perch on the stalks while they eat their seeds. And, after the first killing frost, I dig up the dead plants and have to yank hard to wrestle the thick stems and roots out of the soil. Tomato plants are easy to dig up; their stems are more slender and their vines more fragile than the sturdy sunflowers.

So how difficult could it have been to make a small, rational leap of logic? I should have known that the taller, heavier sunflowers could zap all the soil's nutrients and much of the water into their own selfish roots Meanwhile, the tomatoes could fail to thrive, turning paler and paler green as these mismatched couples stumbled through the summer together. Of course, this is exactly what's happening. The sunflowers already are flaunting deep golden flowers and showing off further by turning their smug faces to the sun. My poor, puny tomatoes – victims of an accidentally arranged marriage – have barely set any blossoms, and my bright hopes for August BLTs have gone the way of the dodo bird.

I walk through my neighborhood nearly every day and can't help but notice that the tomato plants in other gardens are heavy with green fruit – some even turning red. Nobody else is growing sunflowers in the tomato beds, either – and now I'm also starting to worry about my broccoli. I grew twelve plants of broccoli from seed this spring and, with great pride, transplanted them into a raised bed in our side yard in mid-May. A couple of sunflowers had just begun to grow there, too – probably victims of a crow that couldn't carry his entire haul from the bird feeder and scuttled some seeds during his flight. I let those seeds remain in the broccoli bed, too.

For the first month, the two species seemed an equal match. The sunflowers (which had fallen and were growing at the north side of the bed) respected their boundaries and gave the broccoli plenty of space and sunlight. My little homegrown brocs were doing me proud. They soon reached my knees [Full disclosure: I top out at a fraction of an inch over five feet two, so we're not talking about The Attack of the Giant Broc Mutants here] and offered every sign that their stalks would soon thicken and start branching into multiple heads.

Then the sunflowers hit their growth spurt. These plants weren't as tall as the backyard variety, because I think they migrated from the bird feeder, instead of from my garden. But although they are shorter, they are branched and mighty. They're acting like sloppy dates, draping themselves over the brocs' shoulders, ignoring personal space, and hogging the food. This is not behavior an accidental matchmaker condones.

At least I'm not worried about the one deliberate pairing I planted this spring: Around the edges of the bean bed, I sprinkled carrot seeds, and so far, everybody is having a blast in there. If the carrots try to pull off a late-season takeover attempt, our neighborhood bunny will deal with it.
