My Rosella Plants growing very good, I had the first harvest after about 3 months. Now since 2 months there is no sign of new flowers. What Fertilizer should I use?

Any general fertiliser will do.

Wonderful rain and more to come however - will my plot of rosellas that are ready to harvest survive this comfortably? I usually have a dry growing season being west of Ipswich. We have customers for the fresh fruit so I am getting a bit nervous about the fruit until we start picking soon. Thankyou

The dangers of growing a lot of vegies this time of the year is the weather. If you do, then you run the risk of the weather ruining or damaging your crop. 4-5-6 inches of rain in an hour or so can make a mess real quick. That is why I don't start planting until this month. A quick downpour maybe ok, but prolong wet weather could lead to disease, fungus and insects (grubs). Keep a close eye on them. It is your call when to pick.

I have just purchased a mature rosella plant .. It already has fruit. I understand soil conditions needed but am not sure of sunshine requirements. live in NNSW 60 km from the coast. Like your site! Thank you in advance

Hi Bruce, Rod here from Caboolture Qld, about 30klms from coast. From my experience and not sure what you refer to as a mature plant. Rosellas like full sun, like soil to be moist but do not overwater, like a well drained soil, they are known to die very quickly if too wet. I buy seedlings as I have poor success in raising from seed. Up to about 400mm high I remove any small fruit so that they tend to branch out. I planted last year in September and the first flowers appeared about 3 weeks ago. Fruit ready to pick now. My trees are about 2metres tall now. Message back if you would like more info. Cheers Rod

I am in sunshine coast north of brisbane. Q My rosella bush has lime green flowers with a very light pink tinge on outer edges. The fruit is of harvest size but the calyx is green and not red. Any ideas please before the plant becomes compost. Planted early sept. This is the second year this has happened. Seedlings purchased from nursery nearby.

We're taking a break and there will be delays processing comments over the holiday season. Happy Christmas and Happy New Year!

We grow the Rosella bush here in south east Queensland, they make delicious tart jam. Can be mixed with Mango for an interesting blend. I have a half jar left before we return to NZ in Jan 2022. I hope to find someone with a heated glasshouse in Christchurch to grow some from seed. cheers
