growing pumpkins in EarthBoxes

Pumpkins grow like weeds. That’s a good thing. Within days of planting, flat, white seeds crack under the warm soil and sprout. Cotyledons give way to true leaves and off they go. Leaves and stems shoot up so quickly that if you stood still awhile, I’m sure you could see them grow. I’m a fan of every stage.

The size of the leaf is a good indicator of the size of the fruit to come.True leaves are prickly and so are the stems, which are hollow. They remind me of large, green drinking straws. Stems and leaves lead you to think you have a small shrub on your hands, but then strong, curling tendrils appear and the plant takes off down the garden path, up the trellis and around the bend.

A decade ago, before we knew a thing about growing pumpkins, a self-seeded vine grew across the path, into a garden bench, and out the other side. It eventually set fruit, a lovely, heart-shaped pumpkin that hung from the garden bench door. We left the door open the rest of the season, delighted at the rambling pattern and the speed at which it grew. My boys were 3 and 6 that year, so you can imagine the daily joy of discovery. We headed out back in those early fall days to see what those pumpkins were up to.

It’s been such a pleasure growing this year’s crop in EarthBoxes™. They’re right outside my kitchen window, so I see them several times a day. We sit on the deck in the evenings and on weekends, and now feel like we have a ‘fourth wall’ on deck. The pumpkins and sunflowers together formed a beautiful screen.

Here’s a look at their progress since early May.

My stenciled EarthBoxes™ planted with three types of seeds: an assortment of saved seeds from last year (the mystery box) along with Botanical Interests ‘Jack-o’-lanterns’ and ‘Luminas’.

About thirty days in, and look at them grow. You can see the start of the sunflowers near the lawn, also started from seed. I’ll write more about them later this week.

I added trellises to allow the vines to grow up as well as out. The birds land there, before diving in to the sunflower leaves. Why won’t they eat the squash bugs instead?

Golden flowers attract bees and wasps. I love spending time out there in the morning before the heat descends. It’s a challenge photographing the bees. They move in and out of the flowers with speed and efficiency. I still try though. I have about 75 blurred photos, but I refuse to give up.

The vines got a bit of window dressing for Independence Day. They’re beautiful on their own, but a little red, white and blue called attention to their magnificence. They’re wilting in the heat in this picture, but a long drink after dusk set things right.

At the risk of stating the obvious, I love growing pumpkins. Thank you for following along with my gardening obsession.

Did you hear that long exhale? It’s been one of those weeks in the garden.

My decoy pumpkin died…

…and the dreaded squash bugs descended on my beloved pumpkins.

A bit of history

I spotted a single squash bug on the side of the house in early spring. Thanks to a dry, warm winter, they happily overwintered. Further reading tells me they’re a hardy bunch and can survive under a blanket of snow. In any event, they’re back.

The idea was to plant a decoy pumpkin in the back garden, hoping to draw them away from the other plants. I planted three varieties of pumpkins in EarthBoxes™ on my deck, as far away as possible from the ‘scene of the crime.’

Unfortunately, the irrigation in the decoy box stopped working. Pumpkins are thirsty plants, and by the time I realized, it was too late. Whether or not it would have worked is anyone’s guess, but it’s now a moot point.

A colony of squash bugs are now residing om my beloved deck-top vines.

I’ve learned a thing or two from a handful of sites, but nothing that gave me any hope. Apparently squash bugs need the squash to reproduce. They’ll go in search of other food, but it’s not until they find a squash plant that they set up house. Some of the professional growers plant ‘sacrificial’ crops like pumpkins (what!!!) to defer the damage away from pricier crops in the same family. Imagine choosing cantaloupe over pumpkins. Why I never!!!

After last year’s debacle, I assumed the bugs liked the fruit alone and that I would be safe until then. Nope! They lay eggs on the underside of the leaves.

Damage

According to John Capinera of The University of Florida:

The squash bug causes severe damage to cucurbits because it secretes highly toxic saliva into the plant. The foliage is the primary site of feeding but the fruit is also fed upon. The foliage wilts, becomes blackened, and dies following feeding; this malady is sometimes called “anasa wilt.” Often an entire plant or section of plant perishes while nearby plants remain healthy. The amount of damage occurring on a plant is directly proportional to the density of squash bugs.

The plants look healthy. I’ve been knocking the large bugs off the leaves, but I’ve yet to go in search of the dreaded eggs. The bees are a buzz every day, moving from flower to gorgeous flower. A couple of pieces of fruit have reached the size of a baseball.

Developing pumpkin

Regardless of the outcome of this year’s crop, it might be time to take a year off between plantings. I know a lot of gardeners rotate crops for this reason. I took a break from growing tomatoes after a nasty tobacco (tomato horn worm) infestation. They’ve been fine ever since.

I’ll keep you posted.
