Herbicide will help control winter weeds

I have clover in my lawn that has little yellow flowers. It makes pointy seed pods that explode when you touch them. It is taking over my grass, what can I do?
The first thing you can do is to make sure you are growing a healthy lawn. Thick grass will not allow weed seed to sprout and take over. Grass grows slowly in January, and our crop of winter weeds is growing to beat the band.
The weed that you are seeing is called yellow wood sorrel, and in some circles it is considered a wild flower and edible plant folks love to eat it in salad.
But if yellow wood sorrel is growing in your St. Augustine grass you are not thinking about its beauty or its tastiness. It is a tough perennial weed that is difficult to pull and control. The little okra-like capsule will shoot seeds up to 4 feet away.
If you are inclined to use a herbicide, apply one now and use one that is effective on broadleaf perennials. Your best bet is to apply a spot weed killer that contains Atrazine. Only use the herbicide where you are seeing the problem.
Use Atrazine when temperatures are below 80 degrees for three days in a row, otherwise you can damage your lawn. If you have Floratam St. Augustine check the label to make sure it is safe for your type of grass. You can use a granular product like Ortho Weed-b-Gon spot weed killer or similar herbicides.
If you choose not to use herbicides, make sure that you keep the lawn mowed so the weed doesn't have an opportunity to flower and make seed, and try to control the problem by hand.
There are leaves or new bulbs sprouting from my lily plant. Is this unusual? I have put them in water, and they look like they are starting to grow.
What you are seeing is a bulbil or an aerial bulbil to be exact. This does happen on certain lilies and it is one of the ways that lilies are propagated. Aerial bulbils can look like little black "beads" on the stems of the lily. You will see them where the leaf originates from the main stem; this area is called the leaf axil.
You can plant the beads when they are swollen and ripe. These bulbils will soon sprout leaves; this is what happened to you - but on the plant. If they are still doing well, plant them in well-drained moist soil, and in a couple of years you will have good-sized lily bulbs that will produce flowers.
