I have wild onions and violets growing in ground throughout my hibiscus bush! Is there a safe way for me to kill the weeds?
The only safe way is to pull the plants.
If you use a herbicide, you must remember that it will kill not only the invasive plants but anything it touches.

Golden Globe onion seedlings were planted in a raised bed in early April. After a slow start onions appeared stunted. On lifting plants roots were reduced to about half inch, with none with longer root. soil was kept moist but not wet or drenched. What is cause and cure.
You may have chosen a variety that's not perfectly happy in your USDA Zone, so first make sure you have the correct cultivar for your area. There are also two main "strains" of onion that get planted in spring or fall. If you have the right one(s), next check the spacing and phosphorus content of your soil. If all of these factors are in line, there's a chance that if you've had a long stretch of weather where the temperature has been consistently below 70 degrees, that could be the cause of your roots not taking hold and producing onion bulbs.

I bought some spring onions from shop 1 week ago, then I put in glass of water to grow roots. Some of them have grown roots already. I have some 6inch (15cm) small pots. I want to move them into pots. Should I cut them a few inches from the roots? How many pieces of spring onion should I put in one pot? Until how long should I wait the roots before I move them? How long could I grow spring onion? Last time I tried to grow garlic chives and they died after 2 months. I wonder if it chives and spring onion only have short period of life or could they grow until years? Thank you.

The process in Europe, is it also applicable to those of us at the tropics? Can I replicate the process that is workable in Europe also in Africa? Regards, Frank Botu
For the seed saving process itself, yes, the same process is applicable in the tropics. Onion varieties that are adapted to growing in the tropics do need different conditions to produce seed in the first place, so the timing may be different: onions respond to day length to determine when to produce flowers and seeds. Varieties grown in the tropics typically produce seeds in response to short days.
You will also need to make sure there are enough pollinators around, since onions are pollinated by bees and other insects.

I purchased a white onion from the store, and it started to grow roots and leaves, so I planted it today in dirt. Is there anything special I need to do since it is store-bought, and when do they start producing seeds?
It would be best to purchase onion sets from a garden center or nursery.
A store bought onion from the produce section is likely treated for storage and would be unsuitable for planting.
Here is a link about growing onions from onion sets.

We successfully grew onion sets from seeds and have just pulled them for transplanting. Do we let them dry before replanting them? Do we cut the roots and/or the tops before planting the in garden? How long do we wait, if at all, to transplant them to their permanent spot until fully mature for harvesting? Thank you in advance for the info! GOD bless ya!
This link will help you with the process of drying and storing your onion sets.
