Aphid Problems

My rose buses are just covered in aphids and I have tryed to spray soap water on them and they still come back, and I really don't know what else to do they are just getting worse not better. Even spraying them with water is not working.

Aphid are sometimes put on plants by ants. The ants milk the aphids in what is often called "farming". If ants are farming the aphids, you may need to control the ants to get rid of the aphids.

There is a new insecticide for aphid control by Bonide called "Eight" that is quite effective and is more environmentally friendly than some of the other insecticides.

Quackgrass in the Lawn

We had over 7200 sq. ft. of new lawn, including a sprinkler system put in almost three years ago. Last spring we started getting some quackgrass & this spring it is running rampant! Help, what should we use to get rid of it? And most important, what do we do or use to keep it from coming back?

If you have quackgrass, you know how difficult it is to control and how rapidly it spreads. Probably the best and easiest way to control it is to spray it with "Round-Up". Remember, "Round-Up" kills all grasses, so only spray the quackgrass. Then, in about 10 days to two weeks, you can over-seed the area with new grass seed. Dormant roots are apt to come back, so you may have to do some follow-up spraying. There is no way that I know of to keep it from coming back, except for follow-up spraying.

Growing Gladiolas

I need to know anything aobut harvesting the bulbs of gladiolas I also need to know best planting widths and harvesting times I guess just anything you know about harvesting gladiolas and their bulbs.

Glad bulbs (corms) are dug and separated in the fall, when the leaves die back. They are then stored over-winter in a cool well ventilated place, where temperatures are above freezing. In about mid-March, weather permitting, they are planted back out into the garden. The corms are usually planted about 3 to 6 inches apart. Mix some bulb food into the planting area prior to planting. Plant the corms 4 to 6 inches deep.

Bulb Care After Blooming

What should I do for my tulips and daffodils once they stop blooming so that I can get beautiful flowers next year. Do I need to dig them up?

Feed the foliage with a liquid fertilizer. I prefer Alaska 'Mor-Bloom' 0-10-10 for this feeding. The bulbs do not need to be dug each year. Leaves can be cut at ground level 21 days after the flowers die.
