All you need are the basics: water, fertilizer, and weed control. All that other stuff is just a way to move money from your account to their account. The Fruitnut

Yep ... your problem is suckers. You have at least two plants trying to grow in the space for one.. Try to determine which is the original plant and what is suckers. The original plant should look very simple, like this ... Try to see what leaves don't fit the rosette pattern and gently "remove" them. You should be able to gently snap them off where they connect to the main plant. When you are left with just the original plant, it will be more apt to bloom. Any leaves or plantlets you remove can be put in soil to root. This post was edited by aegis500 on Sat, Sep 21, 13 at 20:02

thank you tlbean2004 and christine. I also look forward to hearing what others' experience is with this! I fell in love with oxalis triangularis last year, my work colleague had one at the office, but I only got my first plant a few months ago, then I found that there are other colours and so I ordered more bulbs online. I have now 4 different colours of oxalis ( I'm attaching some pics of them, and my breakfast included ). I have seen in some websites some purple-green leaf oxalis that I have not been able to get yet. Also, in case you are interested (or maybe you know it already), there are many books on floriculture and I decided yesterday to buy one online, so I can understand more about this plant, but in general to have a reference book for other plans. I leave you the reference, mine will arrive in a few days. http://www.pearson.ch/HigherEducation/Agriculture/Horticulture/1471/9780130462503/Floriculture-Principles-and-Species.aspx Have a great day and thanks again for your comments!

I'm no plant expert but with my plants I water not by a specific volume but the volume that is needed for the water to start coming out the bottom of the draining holes, ensuring that all of the soil is wet. Then allow the excess to drain off and do not let the pot sit in water. Let the plant dry out a bit before repeating the watering process. No Schedule with watering. Just when it needs it. As for any other reasons the leaf is yellow I wouldn't be sure. I try to stick with the basics. Sun Water Soil. Sansevierias can take full sun and dont need to be watered all that often in my experience. Make sure your soil is well draining and has some nutrients in there. For the plant food just make sure you are not giving it too much. Dynagro foliage pro is the way to go and i fertilize gently with each watering. Good luck and happy planting =)
