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.

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.

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.

Hi Barbara, I had the same thing happen last year, those plants somehow survived a very hot wet summer and through autumn produced masses of fruit and are also now producing masses of new fruit after I pruned them back hard and started applying a vegetable targeted liquid plant fertilizer with seaweed included. I also added lime around the plants and sprayed the leaves with a bit of epsom salts dissolved in water around the time I pruned them. Don't give up on these ones give them a prune at the end of winter and they will come back for you, if you live in a cooler area you may have to wait til spring but if you get no frost they will come back bigger and better when the weather warms up later this year, caps do last longer than one year and I find they produce much more in the second year than the first, when they put most effort into producing strong stem and branch to support the weight of the following years fruit. Honestly one plant that did this weird year long wait had about 11 fruit on it in March. Sometimes it's better when they start out slow, good luck mate.
