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.

My capsicums have been stripped bare just the stem left about 14 to 16 cm high mind you it hasn't happened to the bigger one's. any advice especially on pesticides?

If this happened suddenly, it was probably hornworm caterpillars--they can strip a plant almost overnight. I placed a bird feeder near my peppers and tomatoes, and birds are kindly taking care of the problem for me...but in the short run you might want to dust with Bt (Bacillus thuringiensis). It's organic, considered highly safe, and will stop the caterpillars from feeding.

Probably some grub/caterpillar, look for killers of these at gardening centers or look up organic sprays on the internet.

Why do the young fruit fall off the capsicum bush ?

My capsicums have just been harvested, should I prune them back (can I prune them) and hope for another crop next season or pull them out and wait to plant seedlings next season.

Ive had the same plants in for 3 years and they reproduce every year. This is the best year yet.

Capsicums will produce over several weeks months. Generally you pull them out when finished.

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.

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.
