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.

I suggest you talk to the nursery people or to their supplier. Also maybe ring someone like Eden Seeds and see if you can talk to someone who knows something about growing Rosellas. Maybe they need time to turn red it does say 5-6 months to harvest.

Are Rossella roots invasive

I have not found the roots to be invasive at all. They tend to form a main tap root with tiny roots branching out from it.

Hi Rhonda, I live in Caboolture, not far from you. Just wondering could we catch up some time to exchange ideas about growing Rosella plants. Thanks in advance Rod

No Rhonda here in the last 50 comments. Start with good rich free draining soil. Add compost etc before planting. Plant at the recommended time. Water regularly - 3 times a week, longer waterings in summer.

good day wondering if you could help me .i have planted 21 rosella plants ,all were growing very well. then 5 of the healthy plants shriveled up and died .at this point the others are doing well but i am concerned.the only thing i can think of is overwatering.the soil is workable but has clay deeper down. thank you.

Here suggests tropical and sub-tropical, you are temperate. I suggest you check the soil moisture before you water each time. Have a little scratch in the soil down 50-70 mm. This will tell you if the soil is wet or has dried out. Little plants a small watering each day or so, when plants have established a good root system less water, like each 2-3 days, depending on soil type and whether winter or summer etc.

If hey get too wet they can die suddenly. I've just had a couple die off quickly.
