Don’t toss those carrot tops: Learn to stretch the bounty of your vegetable gardens

When it comes to harvesting vegetables, gardeners may take a traditional approach with their plants regarding what is ultimately harvested, prepared and consumed. With root crops, we eat the roots. With fruiting crops, the fruits. Leafy crops, the leaves. You get the idea.

However, gardeners may not be aware that harvests from their garden’s plants can be stretched simply by expanding to non-traditional parts of their plants. Stretch the bounty from vegetable gardens and you can save money and grocery store trips. So, where are these “stretches” actually conceivable?

The possibilities are plentiful.

With broccoli, many people focus on the florets, harvesting the main heads and the successive side shoots. However, the stems are also edible — especially when cooked down and tenderized a bit. With carrots and beets, gardeners often discard the plants’ tops. But the leafy carrot extremities can make for an excellent herby additive, and beet tops can be cooked down like greens.

Squash, pumpkin and sweet potato leaves can also be cooked like greens, with the caveat that you’ll want to aim for younger leaves with any type of squash.

Corn husks can be dried and steamed, cucumber and melon rinds can be pickled or candied, peppery nasturtium leaves can be eaten in salads, and even young sunflower stalks can be eaten like celery if properly prepared.

Altogether, this makes for ample extra food that can come from your garden.

To fully realize this extra harvest, however, gardeners need to be committed to protecting the entirety of their plants. It’s not just about the parts we traditionally harvest but also the stems, leaves and other potential food sources. This means safeguarding them from pests, disease and environmental damage. It’s a responsibility we must take seriously to ensure the overall health of our garden.

Regular soil moisture, mulched ground, and a diligently adhered to pest control program are crucial. Monitoring for signs of plant stress should be consistent and frequent to remediate problems before they degrade plant quality. Special attention should be paid to plant spacing, as well. This increases airflow, thereby reducing disease and competition between plants for light, water and nutrients.

Finally, don’t forget to do your due diligence in research before considering non-traditional parts of crops, because not all parts are edible. While rhubarb stalks are edible, the leaves are toxic and should never be consumed. Knowing which parts of a plant are safe and how to prepare them properly ensures you can make the most of your harvest without risk.

To explore the interconnected world of food growing, harvesting, preparation and nutrition, check out the monthly webinar series “Dig Your Dinner.” I co-host this series with Johnson County Nutrition, Food Safety and Health Agent Chelsea Reinberg. We delve into a different horticultural crop each month, providing insights and practical tips.
