Growing Peppers
The Nightshade That Makes You Believe It's Dangerous

We’ll dive into that later, but first let’s talk about the pepper itself.
A quick search for "How many types of peppers are there?" gives answers from a few thousand to more than 50,000.
It’s safe to say we won’t have time to cover them all, but thankfully, the basic growing requirements are very similar across varieties.
You can even grow different varieties side-by-side without worry. Cross‑pollination can occur, but it only affects the seeds, not the fruit you’re eating now.
Peppers love hot weather, and they love the sun. In my area, though, they do benefit from some mid‑to‑late‑afternoon shade to prevent sunscald when the sun is at its most intense.
I find 50% shade cloth to be ideal for this. It lets the rain through, doesn’t restrict airflow, and blocks that intense afternoon sun.

Peppers prefer:
• hot weather
• full sun with some protection
• rich, loamy soil
• pH between 5.5–6.5
• 1 to 2 inches of water per week
• balanced fertilizer once a month
I usually apply a general-purpose fertilizer such as triple-8 or triple-10 at planting time, followed by light fertilization (half strength) every month throughout the growing season.
Tip: Go easy on the nitrogen once the plants take off. They do need it, but too much will cause rapid vertical growth and almost total stoppage of fruit production.
Peppers can take from 60–90 days to start producing, but once they start, they'll continue to do so until frost.
Like other nightshades, peppers will pause fruit production once temperatures reach the 85-90°F range. If this happens, don't worry — keep them watered and lightly fertilized — production will resume once temperatures drop back down.
Here's a fun one: Many folks don't realize peppers are actually perennials. Most of us grow them for the season, clean out the pots and start fresh the next year. But with just a bit of effort, you can overwinter them very easily.
To overwinter peppers, prune the plant to about 12 inches, remove the leaves, and let it go dormant. Keep it in a location that receives about 6 hours of light each day with no chance of frost, and water them sparingly. This gives you a great head start on next season.
That’s it! Peppers are easy to grow, easy to maintain, and given the right environment, provide a lot of fruit for the effort.
Now, here’s the fun "trickster" part for all of you pepper lovers.
It’s true: Capsaicin has no thermal heat whatsoever. It doesn’t raise the temperature of your mouth or burn your skin. Your body reacts to it as if it’s been burned, but the sensation is purely perception — your nervous system is firing off a false alarm.
Capsaicin binds to nerve receptors, the same receptors your body uses to detect actual heat and physical burning. You may even have a physical burn response like swelling, flushing, or tearing up, but at normal culinary levels — think jalapeño or even habanero — it isn’t doing any physical harm.
I know it’s wild, right? And at this point, you might think I’m crazy — but I promise I’m not.
Capsaicin tricks your mind into thinking you have put yourself directly over a flame, and while your body reacts to that, it’s not causing any physical burn at all.
It would actually take a very high concentration of capsaicin — one far beyond that found in peppers we typically consume — in order to do any real damage to you.
The real kicker is this “heat” generally only affects mammals. It doesn’t bind to the receptors in birds. They can eat the seeds all day long — even from some of the hottest peppers — and never feel a thing.
Capsaicin is one of nature’s amazing defense mechanisms designed to discourage mammals from eating the fruit while still allowing birds to spread the seeds.
Happy Gardening 🌱
