(Best months for growing Chilli peppers in USA - Zone 5a regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • P = Sow seed
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 64°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.
  • Compatible with (can grow beside): Best grown in a separate bed as chillies need plenty of light and air circulation.

David, In their native Mexico, jalapeño peppers are eaten when they're green. Wikipedia has a useful article.

Like Ty (25/2/09), I too have small worms/grubs eating my chillies from the inside. Not sure what to spray them with.

Cliff. I have noticed my jalapeno chilli get a purple/brown ish tint before they start going red. It should start going redder in a couple (4) days

Hi Cliff, sounds like you have bought Siam chillis, usually sold in stores such as this and are more of a decrotive plant (I have a few for extra colour in my front garden grown by my step daughter), personally I'm not a fan of the flavor but are quite hot. Also look good in an Olive Oil bottle that you use for cooking!

Hi all, new to this growing lark. We have a couple of Chilli plants that are fruiting well with lots of unripe chillis they are grown in raised beds and purchased from a well known DIY hardware store, my only concern is I have noticed that one chilli appears to have a purple coloured mark on its side. I am wondering is this the chilli starting to ripen or is it some Monster about to engulf my chilli plants and I will go out one morning to find nothing but a stem. Any advice would be appreciated.

I have a few Naga Jolokia plants growing, they are flowering, but not producing any fruit, any ideas how I can get them to produce fruit? Also how do I go about collecting seed to grow more at a later date?

You may need to give them an extra helping hand in pollination. use a dry toothpick or similar, and gently brush it around in all the flowers, and see if that helps. I have African Birdseye x Thai chillies that did the same for a month or so. After that (mid-summer) they fruited just fine. If that doesn't work, then try adding in a little extra fertiliser, but don't go overboard. Also, water kills pollen, so try not to spray the plants with a shower from the hose, so much as a slow soak from the ground.

I don't mean to be rude, but would like to clarify a few things that have been said here, and give a bit of information. The Bhut Jolokia is supposed to be ~1.5 million Scoville units in heat and is realistically about 1 million, compared to a Habanero, which is usually ~300,000 Scoville units. The habanero is too hot for most, and the Bhut Jolokia is only for the diehard Chilliheads. Scotch Bonnets, Habaneros, and Bhut Jolokias are all Capsicum Chinense, whereas the standard chillies (pointy-ended ones) are Capsicum Annuum, and are usually alot more mild. Sweet Bell Peppers (Capsicums) are C. Annuum, and can cross-pollinate with other Chillies. Kate - Chillies are usually fairly slow-growing plants compared to things like Tomatoes etc. Right now, it may be too cold for them to be in full swing. The flowers are self-fertile, so will pollinate themselves, but you need to help them along by sticking pollen to the Pistil using a cotton bud or similar. Swirling your finger around gently inside the flower works too. When the fruit is pollinated, the flower will go brown, and drop off, and the fruit should start growing. Flowers browning and dropping could also be due to a poor feeding regime. On most (all?) fertiliser bottles you will see a NPK number set. N=Nitrogen, P=Potassium, K=Phosphorus. General vegetative growth (leaves/stems) is encouraged by high-N analysis fertilisers, and flowering is encouraged by high P/K analysis fertilisers. At this time of year, I have my chillies inside on shelves in front of a large west-facing window. Usually, I find that if the overnight low temperature drops below about 5 degrees C then they will stop growing/flowering. I would try and be patient with your Capsicums and Chillies. As they are already established, you should get a good head start this season. Good luck!
