I have a birds eye chilli bush that a friend gave me half grown that was in a pot. My husband transplanted it in backyard with commercial potting mix. My problem is the bush has plenty of flowers but no fruit. What can we do so as the bush will yeild chillies. I live in Townsville, Nq. Any help would be most appreciated.

I know the teply is late but try a bit of potash to up the potassium and avoid nitrogen heavy fertilizers during the flowering season.

Its probably a little late to plant out in the garden BUT you can grow them in minature greenhouses year round that can be bought from bunnings or masters .

Try feeding fortnightly with Yates Thrive flower and fruit soluble fertiliser. I have never had problems with lack of heat. Also make sure you keep your jalapenos away from any other member of the capsicum family ad they may cross breed and produce fruit that is not consistent with its original description.

'Cross breeding' can only affect plants of the next generation ie the offspring of your current jalapeños

Hi, keen to start growing some naga or similar - I'm based in Sydney and am aware that summer is ending as I write this, will this delay the germination/growth/harvest or are they quite resilient to seasons? I intend on using a heat map in my apartment to begin with, before potting and moving outside onto a balcony. Let me know if this sounds like it'll work - all advice appreciated!

Mine too. It's usually because of too much water as chillies dont like to be coddled. Nothing you can do for the ones already on the plant.

Sand would be too heavy. You need to add compost or other organic matter into the soil when planting. To loosen soilup. Chilies/peppers do better in soil pH 6.5 to 7.0. Helpful info link https://bonnieplants.com/how-to-grow/growing-peppers/
