My dad did the same for my mum out of a piece of metal gal tube or stainless tube (I think it was out of a bicycle pump??) He put a bit of tube over it so it wasn't sharp for a handle, works a treat. I still have the one that he made for me as well.

Just had my wilting rosella plants diagnosed by the nursery where I bought them. They said it was typical of too much rain/water - so grow them high and don't mulch during heavy rainy periods like - A nematode or two on roots but not enough to kill a plant starting to flower like mine - suggested to water with a weak solution of condies crystals and interplant with marigolds to discourage nematodes. Bought 4 new plants to try again now that the big wet seems gone.

Trying to find a cure for my rosella plants wilting - we have had very very wet and humid weather, so put it down to that and have been trimming back the wilted leaves and cultivating around the roots to aerate them, seems one plant has new shoots. Or could it be nematodes - don't understand much about them - then again the scrub-turkey and quail scratching around them could have exposed the roots ??? Any advice welcome. Cannot seem to find anything helpful in the myriad of books and web-sites I have been scouring over the last week.

The wilting may be due to a fungal infection in the soil. The fungus enters the roots and into the plants stems then into the leaves. The wilting is a sign of stress. There are several causes of stress such as too much water or not enough, and poorly drained or compacted soil. You need to tackle the problem as soon as the wilting starts. If the plant is in full sun then the heat places the fungi infected plant under more stress. Place some shade over the plant such as an old umbrella for a start or, if possible, remove the plant and place it into the shade. Pick off the yellow leaves so that the plant does not waste energy in causing them to drop off. Leave the green wilting leaves alone. Treat the plant with an appropriate fungicide. If you leave the plant in the ground you might consider using worm casting. You could call a garden club that has hibiscus enthusiasts to seek advice.

One thing I have found about growing Rosella fruit is that the bushes need to be in very well draining soil - otherwise you will get wilting/rotting. We have a very sandy soil type and our plants just love it.

Hi There I moved to Bellingen 3 years ago and have been growing Rosella every year since arriving. I first tried growing them in tyres and they were great. Trying pots this year. I bought 10 seedlings that were about 5inches high from the local market. I got 10 x 42 litre rubber tubs with handles ( those colorful ones ). I drilled 12 holes in the bottom of each and 6 around the lower outside about two inches up from the bottom. Put some broken pots or stones at the bottom for drainage and fill with nice soil, compost, manure, lime and anything else that would give the plants a great start, but i waited about a month before transplanting the rosellas as i wanted to make sure everything blended together nicely. These little trees are now growing nicely and because of the handles I can move them around if I need to. 1) Don't drown them....They don't like wet feet but don't let them dry out either and cover them with mulch. 2) They love sun but will survive in filtered light. 3) The plant will grow about 5/6ft tall and Fruit will start to appear as it's maturing. 4) The best time to pick the fruit is when it's about 5 or 6cm long 5) Use scissors and don't cut too close to the branch.....cut at the bottom of the fruit and leave the little stem on the tree. By doing this you just might get another lot of fruit before the trees dies off. Yes it will die after fruiting and you will have to plant new trees next year. By the way, the flower develops first but will only be in bloom for one day. It resembles the hybiscus flower and the fruit will take about 3 weeks to develop after the flower blooms. When they're ready I pick a few of them every day and I store them in freezer bags until I have enough for Jam. Take the pod from the petals and freeze them in separate bags. Well worth growing and If you need to know more let me know Good luck Wendy
