Cultivate Prosperous Peppers With Friendly Companion Plants

With temperatures soaring, brighter evenings, and longer days, summer is right around the corner. What's better than welcoming the season with some fresh new plants for your garden? Summer is the ideal growing season for pepper plants.  Just like humans, peppers long for companionship. Well, not really, but peppers do grow better when they have companion plants near them.

Pepper plants are an extremely popular vegetable to plant, and we can see why. There are hundreds of varieties, ranging from hot peppers to sweet peppers, and everything in between. Peppers thrive with lots of time spent in the sun- 6-8 hours a day to be exact. They also love to climb up a trellis or grow in raised beds, depending on the species. Peppers share the nightshade family with tomato plants, making them a common vegetable.

Summer is synonymous with grilling and there's not much better than grilled peppers and veggies. Growing your own is not only a labor of love, but can produce much tastier results than the store bought equivalent.

What is Companion Planting?

A gardening hack for producing successful plants is companion planting. According to Treehugger, "Grouping complementary plants (companion plants) together in the garden to benefit each other, can be done for a variety of reasons, such as to provide shade or a wind barrier to other plants, or to cover the surface of the soil with edible plants to crowd out weeds, or even to help boost the growth, flavor, or yields of food crops."

It's a win-win for any gardener who wants to grow peppers while filling up their vegetable garden with other delicious plants. Growing plants together and using trap crops can help keep away pests like bean beetles and hornworms, among others. Common companion plants include marjoram, allium, borage, kohlrabi, legumes, and even parsnips and turnips.

The flowers are bisexual and zygomorphic, with five petals, a superior three-carpelled ovary, and a funnel-shaped nectar spur at the back, formed by modification of one of the five sepals.

Keep Your Peppers Thriving

Not all insects founds in the garden are a death sentence to plants. Ladybugs are beneficial insects you'll want around. Aside from being cute, they survive by eating aphids. Since aphids love to attack peppers, you'll want to keep ladybugs around as a natural repellent.

In order to keep your peppers growing, avoid planting anything is the brassica family, like cabbage, brussels sprouts, broccoli, or mustard greens, as well as fennel.
