i have 2 capsicum plants supported by trelis's. they're both about a metre high. they produce small-medium green to yellow chilli shape fruit, but if i let them get to yellow, they go rotten and soggy. dearly after red capsicum - any hints? many thanks :)

I have 4 capsicum plants outside in my garden, 2 have green fruit on them, but now one has started to show black coloration on the bottom of the fruit, still seems very firm and still growing, I just am wondering what to do, as if it is diseased I don't want to infect my other plants.

Hiya Kay .... Don't stress as this is part of the ripening process. The darkish bottom is a sign that the fruit is chaniging from green and ripening into the red capsicum like those you buy at the supermarket ....not unlike an apple that is green and turns to red when ripened. Hope this helps. Cheers Michele

Hi! I have 3 capsicum plants and I am getting fruit on them but they do not grow large; one is a purple and 2 green; the fruit on the green plant start to rot before ripening. I give them plenty of water and fertilizer. Can anyone tell me what I am doing wrong??

I have three mini capsicums, each in its own pot, purchased from a very reputable source. The red one produced one minute and one tiny capsicum - and they were on the plant when I bought it. The brown one has a single tiny capsicum. (They are supposed to be 5cm across.) The yellow one has only tiny blossoms. I put them into new potting mix, added a little chook poo, new pots, watered with seaweed solution, good sunny spot. I live in northern part of Sydney. I have dealt with white flies by spraying with Natrasoap which has finally worked.

Hi, I'm growning capsicum in Perth. The flowers keep dropping off and I'm wondering why?? Any ideas? Thanks

They might not be getting pollenated, also give it a boost with pot-ash.

Blossom drop is common early in the season. The number one cause is that temperatures are not yet quite right. Like tomatoes, if it is too cool or too hot fruit will not set. Capsicums like night time temps to be above about 16 C for fruit set. Also if daytime temps are too high (above about 35) fruit will not set. There is probably minor variation among varieties in the actual optimal temperature range, but you get the idea...Generally patience is the only remedy required. Other possible causes are not enough airflow (capsicums are primarily wind pollinated), too much nitrogen, not enough water, too much water...

Ive had capsicums and chillies over winter and they usually come good once it warms up. I prune them back and when it gets warmer you should find new leaves starting to emerge. Give it a good feed. The old leaves will eventually drop off. I had a chilli plant live for several years in a pot.
