  • Space plants: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.

Hi. I have some original old very very hot chilli's that i saved from my Mothers plant which was originally her mothers plant.. They have been in the freezer since 1995. The seeds have an emotional attachment and i would love to be to grow these seeds into plants and hand onto the next generation - if it is possible. Having been in the freezer as a full pod - Would the seeds inside the pod be ok ? Would the plant cope outdoors with constant breeze? Any or all Advice would be much appreciated. Thank you

Hi Steve Seeds from your frozen whole fruit will not be viable. Seeds stored in freezer after drying at least 80% will keep viable in freezer but not fresh. Sorry

I would still try and grow some just in case.

Go on the internet and do some research about saving seeds. Some seeds need some curing first before putting in the fridge. I don't know whether it is/was a good idea to put in the freezer - other people here might know. Example - tomatoes need to be fermented in water to take the gel case off the seed before drying and then put in a bag and then into an air tight jar and put in the fridge. When taking that jar out off the fridge let it sit for 20-30 mins before opening it. If opened straight away condensation can happen and maybe ruin the seeds. You can only try - plant a couple of seeds to see if they germinate and then grow in a place protected from the wind a bit. Do some research to try and find a company/??? who can advise about your situation. Google something like - seed saving companies or seed saving bank. Good luck

Do chilli plants need plenty of water? My bushes look healthy but the leaves and flowers keep falling off. Thanks

Depends on the soil type. Small plants need small waterings regularly - each day in summer especially. Larger plants need a bigger watering less often - each 2-3 days. Pushing your finger in the soil will tell you if the soil is dry or wet.

Your peppers and chillies will do better with some shade cloth on top, not more than 50% shade, they are stress with the heat and they start to drop leaves and flowers.

try PEPPER JOE'S in the USA, specialised in super hot chilies. Mails seeds to Australia, with a good germination rate.

Hi, I have chilli plants and capsicum plants all around the house. (As well as tomatoes, basil ,herbs etc) All of the shoots and new flowers on 95% of the plants are eaten to the stem. There is no sign of any pests?

Do you need to take off laterals? Or just let them grow up as they wish??

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
