Hi, Our capsicum plants are loaded with fruit and are flowering profusely. To increase the size of the fruit do we thin the fruit or just let them keep growing. Thank you any advice will be appreciated.

I would suggest you stake and support the plants. You probably could do both, leave all flowers on some and trim others. Good watering and fertilising will produce good size fruit.

Hi, I have 4 Capsicum plants and i use worm fertiliser and water on the days I can and i will all so use bath water and I have had flowers and that's it .

Depends whether you are using worm leachate or worm casting as fertiliser. I don't believe they have much NPK in them especially the leachate and I think you would have to use a lot to grow things. Although it says you can grow caps in summer I think it is far too hot to do so. Better a crop in autumn and early spring.

Hey guys, My capsicum plant is giving me a lot og capsicum but they are small and changing colors while they are still small... any advise on what might be the issue

Probably not enough fertiliser and also I feel it is too hot this time of year to grow caps.

I’ve noticed my capsicum is very small this year same as last year. Has been in for about 6 wks and is only about 6-7 inches tall. Been regularly watered and fertilised?

Check the NPK of the fertiliser - seasol and similar things are not fertilisers. You would have to consider what the soil was like before you planted. Did you have another crop in before planting the caps. It would have used most of the nutrients up. What is the ph of the soil, the soil temp etc. Where I live we are having temps of 3+ degree above average and no rain. Too hot to grow most things I feel.

I have one plant with lots of flowers but no capsicums in sight. This is the first time I have struck this as I've grown the very successfully in the past. I have a large net enclosing all of my vegie plants to keep the butterflies and birds away. They get plenty of water and fertilised with seasol about once a fortnight

Seasol is not a fertiliser. Do some research on fertilisers. I pulled some capsicums out today, plenty of flowers lately, little fruit developing, not many growing to full size, a lot being burnt by the sun. It's holiday time for the garden and myself.
