I live in the northern suburb of perth wa and i am growing 3 capsicum plants in an old water tank. I purchased proper vegetable soil and fertilise weekly with seasol and npk every 2 weeks and water nearly every day, due to the hot weather we have at the moment. I have lots of healthy fruit, but have noticed that the leaves on one of the plants have turned yellow, what could be making them turn yellow?

Hi Simone, the yellowing of leaves generally indicate that the plant is not getting enough oxygen, perhaps due to too much water. I find that with my rose plants. I shall assume that this maybe the same in your case. Please ask anybody else if my theory is correct. Good luck.

Hi, If you live in Perth and are using tap water then the water is way way to alkaline. Some times in Perth the water reads PH 8.00 and above. When the water is that high they will not up take nutrients. I would suggest getting a container and adjusting the ph. before watering the plants. Regards, Barry.

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 :)

Probably blossom end rot. Add some garden lime to your soil.

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.
