You have (probably) planted a kind of capsicum the grows long and thin - mixed sweet caps. You have not planted the normal caps - round caps. Google how to grow caps or peppers and read about the different varieties. The guide on this website will tell you how long they should take until ready to pick and eat - something like 10-12 weeks.

Hi Lyndal, It's probably too late for your capsicums now. The only thing I would suggest is pick one or two that feel like they are almost ready, and leave them in a window sill to ripen. I did that with the last few capsicums from our crop this year, before pulling them up.

I have been harvesting my capsicum since early summer. They still have fruit and flowers. Should I pull up when I have picked the capsicums that are nearly ready. I want to start my winter garden and am not sure whether they just keep on being generous in their supply.

As the winter sets in capsicum yield will diminish and a good frost will kill the plants. Capsicums are a short-lived perennial but you would be best to harvest what you can and then pull the plants out giving you room to plant your winter garden. Fresh plants in a new spot next spring would be best.

My capsicum bush is loaded but the fruit is very bitter. How can I sweeten them up?

Adding Epsom Salts at the rate of 1 tbs - 2 litres of water will improve the flavour and sweetness of tomatoes so you could give that a try. They are both in the Solanacea family. All the best.

do I need to stake a capsicum plant whilst it is growing?

Hi Maurie, capsicums grow fine without staking, however I found that once they start to bear fruit, they lean down to the ground. Staking might help keep your capsicums off the ground.

Normally capsicums make a sturdy, self supporting bush. If they are getting tall or leggy a stake would certainly help and would avoid the disappointment of a plant being blown over when it was laden with fruit.

Yes they do fall over sometimes. I have put up a little trellis this year. I had a 4" diameter split pine rail post 7 feet long - cut it in half - put them about 15" into the soil, 5' apart - I have 4 plants in. Drilled some 1/2" holes approx. every 9" and ran some twine (Bunnings 500m $12) between the posts around the outside of the posts. The plants are now just starting to come through the bottom lot of twine. I have done the same with tomatoes - posts are 7' out of the ground - I have a 6' steel post in the middle. If I have to, when the plants come through the twine I will pull the twine together and tie to the steel post. All a bit of an experiment this year to see how it goes. Did a lot of reading about growing indeterminate tomatoes and found I couldn't buy suitable wire netting to make cages. Very expensive also. I had the split rail posts from a shade structure I had pulled down, so it worked out very cheap. Use the twine around my snow peas also.

Could be a number of reasons ... A common ailment with capsicum is blossom-end rot. This condition just effects the fruit and not the plant blossom or flower. The condition gets its name because the symptoms appear at the ‘blossom end’ of the fruit. The first sign of blossom-end rot is that the end of the fruit becomes off-whitish to brown in colour and takes on a ‘sunken in’ appearance. As the fruit matures, these symptoms become more pronounced and the colour of the rot becomes dark brown to almost black. Blossom-end rot is caused by insufficient calcium supply. However, the most common cause is from irregular watering during the critical growing period of the young fruit. Even when calcium levels in the soil are sufficient, a plant receiving insufficient or irregular water will have difficulty absorbing and delivering calcium to the fruit. To control blossom-end rot. Boost the soil with calcium by adding lime, dolomite, gypsum or composted animal manures before planting the seedlings. Water regularly. Most capsicum crops continue to flower and bear fruit for prolonged periods of time, so ensure the soil around their roots is kept moist. Avoid fertilisers with a high nitrogen content. Nitrogen fertilisers will promote leaf growth at the expense of fruit, allocating calcium to the leaves instead of to the fruit.
