Hibiscus plant

I've had a lovely potted hibiscus for about 6 years. It's 4' high. This year it got aphids. We've used an horticultural strength spray (my daughter is in landscaping) and also one purchased at a garden center to no avail. We have drenched it literally and they still survive. We tried to re-pot it but left some dirt around the roots. through all of this it still blooms. I put it outside until we can figure out how to get rid of the aphids. Any solution would be appreciated.

Michgan Holly

My Holly bushes were getting to big so last summer I trimmed off some big branches. Now, I don't know if it is that or because of the severe winter we had (as I have seen other holly bushes recently at different locations with brown leaves and they had not been trimmed). My son's open house is this summer and I am really hoping that these holly bushes recover as they are right at the front of my house. Do you think they will recover and get new green leaves? I have never had this happen before. Thanks, Diann

Trees for hillside with poor soil

Our townhome complex backs on the Mariemont landslide site. The contractor in shoring up the hill had removed all forestation. We are in need of trees that would provide a visual barrier to the rear of the shopping plaza, as well as making the bare hillside more attractive. The soil is poor and access to water very limited. We are seeking advice on hardy tree plantings that could survive in such conditions. What would you recommend.

Blue Spruce issues

I have several large blue spruce trees 30'+ tall and I live at about 6200 ft elev. SW of Pueblo, Co. These trees are about 35-40 years old. Some of the lower branches that normally drape to the ground are beginning to die. Maybe 2 to 4 ft up from the ground. Also some of the tops appear to be thin with needles falling or being blown off. These trees are adjacent to lawn watering areas so shouldn't be affected by drought. I live about 10 miles from the greenhorn mountains. Any thoughts on what may be the issue other than some type ips or pine beetle bug? If it's a bug they are probably dying and not much to be done at this point.

Rose winter damge

One of my hybrid tea roses seems to have been severely damaged by this past winter. All the branches seem to be dead. However, since the weather has warmed a bit, growth is occurring directly from the root joint right where it just breaks through the soil. Is this the rose reviving or is it likely to be growth from root stock which may in fact be a different variety of rose?

I have a trellised mature pyracantha growing up my garage wall. It has grown vigorously the past 8 years or so and I always have to trim it every year to keep it in from growing over the garage roof. But after this terribly cold winter, all the leaves are dead. However, when I cut a twig or branch there seems to be green cambium underneath the bark. But it doesn't have any leaf buds that I can see (now 3rd week in April). Do you think it will revive or should I cut it down? If it is savable, what steps should I take to save it?

Straw Bail Garden

I live in Freeport in Brazoria County renting a home. I would like to plant a garden but the cost of building a square foot garden isn't in our budget. I was planning on just using pots and planting a few tomatoes. I came across this website Many of the people who have left comments seem to be in the Northern United States. I am more curious if this method would work here in Texas. Thanks!

Aspen Tree Death, Cedaredge Area

What must we do to better maintain our Aspen Trees? They appear to dying at a faster rate than ten years ago (2003-04) in the Cedaredge area at 6100 to 6500 feet altitude. Is it caused by ozone depletion, global warming, insects, or some disease? Can the trees be saved? Mark

My small raised bed is full of this white fungus or mold. It is just below the surface and goes downs at least a foot. In past years I have added compost to the soil, but this is the first time this has appeared. I cannot identify it, so I don't know if it is harmful, beneficial, or neither. I have been turning the soil and exposing the white material to try and dry it out. I would like to know what it is before I plant any vegetables. Thank You.

Okame cherry tree is not flowering or leafing

This question concerns an ornamental cherry tree, an Okame, that is not yet flowering or leafing out. I live in Havertown, PA, and the other Okames on the street have already flowered and are now leafing out, but not mine (which is approximately 11 years old). The buds have remained small and a few show a hint of pink, but not many. Last year, after it flowered, I noticed that although it leafed out fully, the leaves were not as big as usual and they dropped off the tree earlier than usual, though still in the fall. Any thoughts on what is ailing the tree and what recourse there might be? Is it safe to plant another Okame nearby? If not, what is the waiting period? Is there somewhere that I can take a cutting from the tree for diagnosis? Please advise. Many thanks.

This weed has taken over my Bermuda grass yard!

The weed in the attached photos is now covering my yard. It really gained momentum a few weeks after I used Scott's Weed n Feed in mid March. I thought it might be nut-grass but I'm unsure.

What should I use to gain back control of my Bermuda lawn in Frisco, TX?

Thank you! James Greer Class of '77

boar selection

I'm Kathy Bottorff, the sec/tres of the Red Wattle Hog Association. I also write our newsletter. I'm currently looking for information on boar selection. Why its so important and what to look for. Boar selection on an heirloom pasture hog for small farmers can be quite different from larger commercial operations. Can you direct me to the proper materials or perhaps someone there would even consider writing an article for our newsletter.

Control of Peach/Nectarine Leaf Curl in young trees

Holes in zinnias


I started my zinnias from seeds and they are growing nicely. Some of them have two sets of leaves and some have just one, all in all they are at different growth stages.

I noticed that many of the seedlings (if that is what they are called at this stage) have holes in the leaves.

Can you tell me what might be causing the holes? I read it could be aphids, snails and some other things. I read about some of the possible treatments. However, I don't want to treat them without knowing what may be causing the holes.

Can you help me with this and tell me how to treat the zinnias? I don't want to lose the flowers.

Thank you!

Can you provide a recipe for vermicompost tea?

I sent a question to you maybe a week ago asking if you could provide a recipe to brew vermicompost tea and have not received a reply. I would be very appreciative if you could reply. I also would ask, being as I have sowed grass seed 4 weekends in a row and the later seeding is just sprouting, when should I mow the lawn for the first time?
