Any hot pepper you want to grow will do fine in San Pedro assuming you're not RIGHT on the beach as the fog and salty air could pose a challenge. But since you're able to grow all those other veggies you mentioned, you should be fine. I love hot peppers too and find the selection at nurseries disappointing. Seed catalogs and seed swaps are the way to go. I like Baker Creek because they have free shipping no matter how small the order, though sometimes they're out of stock a lot. My favorites to grow are shishito, which isn't hot but is VERY productive, scorpion, cajun belle, kimchi, and Chinese 5 color. The biggest thing I wish I knew when I started growing hot peppers in SoCal is that they NEED shade cloth during the hottest months, or else the plants will get sun scorched and the flowers won't set fruit.

I suggest you will have to buy seeds and germinate them.

Hello, I want to grow chili peppers (Scotch Bonnet) soon but I see that it may be outside of the growth period. What advice would you give? I live in Long Beach, CA.

Wait until it says when to plant is a good idea. The guide here says this is the best time to grow it, to give yourself the best chance of a good crop. Now you can start a little earlier or later but you may not produce as good a crop. Then you have to take your weather/climate conditions into considerations. This website isn't spot on all the time. They might say plant beans from fall (autumn) to spring, but the bean fly kill mine in autumn so I only plant in the spring. Where I live it says grow egg plant in warm weather, spring to late autumn. I have picked it all through winter. Sometimes it is all about trialing things or just having a go.

Just my observations. I am in zone 8a. I built my first lasagne bed in the fall of 2018. Then planted n spring of 2019. I experimented with a variety of chiles. Poblano, Thai, Cayenne longs, Pasillas, Italian sandwich, Sweet Bells, and Jalapeño. The bed got full sun, I planted closely, and harvested 472 mature chiles. Every variety produced heavily. This would seem to contradict your data, that chiles need growing room, and good air circulation. The “ stems” were more like trunks of a two year old fruit tree. Almost 2” in girth and very sturdy. I submit this data not to gloat, but for further consideration. Thank you!

Jim what date did you plant your chiles? I'm new to the area and gardening and want to plant poblano peppers. Thank you

Hey Jim, How many plants did you plant in the bed? One of each? I'm doing a variety of chili peppers in containers this year and your comment gives me hope that two plants could fit in one 7 gallon grow bag. Thanks! Best, Colleen

Thanks for sharing!! I have had huge trunks before on ours as well because we planted them in front of our hen house [bedding was tossed out in that garden area all year] and they were HUGE by October and loaded to the point of cracking a few "branches" from the weight... LOL! I think the same thing... They just like a lot of sun and nitrogen and water at least once every week or two.... Didn't seem to matter much about spacing and the closer they were the less breakage it seemed to have. :-)

how long does it take for chilli seeds to start to show in a seed tray. I've put mine in almost two weeks ago and no sign of them yet.

I'm in Ft. Lauderdale Florida (10B). I have the same issue. I've got a plethora of differing varietals that I germinated outdoors in Solo cups beginning in March. Some plants are 6"-8" tall while others are just starting to sprout. My Thai Chili Peppers are growing exceptionally well while the bell peppers are taking there "sweet" time getting here. The struggle is real.

I'm actually in Thailand but your site doesn't list that. Having a hard time growing chilies here and looking for any hints. Soil has plenty of nutrients but does not dry out due to the rains and clay underlayer. At this point I'm thinking of adding sand to the soil to aid in drainage. I've dug a hole in the garden down to the clay layer and filled it with water. It drained within 5 minutes so it's really about my topsoil quality. Thanks!
