Wondering What Not to Plant with Peppers? Here’s What to Avoid—and What’s Worth Trying? ›

Brassicas: Almanacs and home gardeners recommend avoiding planting brassicas (cabbage, broccoli, kale, collards, cauliflower) near peppers because they require different soil acidity levels and can deter pepper plant growth.

Brassicas: Brassicas such as broccoli, cauliflower, and cabbage are not good companion plants for peppers as they require similar nutrients from the soil, which can lead to competition and reduced yield. They also attract pests such as flea beetles and cabbage worms that can damage pepper plants.

The main benefits of planting peppers and tomatoes together are maximizing yields from a small space, optimizing soil conditions, concentrating water and nutrient needs, and attracting the same pollinators. Both of these veggies can both be trellised to maximize their yields.

Coffee grounds can contribute to a healthier soil environment for your pepper plants. Here's how: Enhanced Drainage: Coffee grounds have a slightly coarse texture, which can help improve soil drainage. This is particularly beneficial for pepper plants, which prefer well-draining soil to prevent root rot.

Beans, in particular, are not good jalapeno pepper companions and should not be planted near them. Peas should also be avoided. Anything in the brassica family are not good companions for jalapenos.

Brassicas: Almanacs and home gardeners recommend avoiding planting brassicas (cabbage, broccoli, kale, collards, cauliflower) near peppers because they require different soil acidity levels and can deter pepper plant growth.

In a raised bed, various herbs such as basil, parsley or dill are good companions for peppers. Lettuce, carrots and onions also make good neighbours for peppers in a raised bed.

Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass. Conversely, grounds (used as mulch and compost) improve yields of soybeans and cabbage.

Not all plants like coffee grounds because they are slightly acidic, contain caffeine and are nitrogen-rich. Some plants that won't thrive in these conditions include vegetables like Chinese mustard, grasses like Italian ryegrass, rosemary, lavender and flowering plants like geraniums.

Plants like tomatoes, peppers and eggplants in particular will benefit from shell fertilizer, Savio said. The extra calcium will help prevent blossom-end rot. Broccoli, cauliflower, Swiss chard, spinach and amaranth are also calcium-packed and could use extra from eggshells.

Can cucumbers and peppers be planted together? ›

Cucumbers and squash plants pair well with peppers because their low growth habit shields the soil from direct sun, prevents weeds, and keeps your soil from drying out too quickly. If you choose to grow cucumbers as groundcovers without trellising, try adding organic mulch around your plants.

A: Yes! Marigolds are incredibly easy to grow and make great pepper companions! A great pest deterrent based on their strong fragrance, as well as their ability to repel nematodes through their roots, marigolds are a long-standing pest deterrent in the vegetable garden.

Vining vegetables like cucumbers actually make perfect companions to bushing veggies like peppers. They enjoy similar growing conditions and can grow together in about the same amount of space as a single plant. Ensure you trellis your cukes and plant your peppers in front so they aren't shaded by growing vines.

Multiple pepper plants (of the same or different varieties) can be planted together and, in some cases, can help each other out. For example, planting a border of hot peppers around sweet peppers is likely to deter any pests that thought about munching on either of those plants.
