Bugs are eating my rosella bush. What natural spray could I use? Thank you

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
