Getting rid of Lily of the Valley #422904

Asked 2017-08-23 02:42:13

We have a substantial bed of lily of the valley in our front yard, and it keeps growing every year.  We are doing some major grading to try to alleviate water in our basement, and we want to take out the lily of the valley. I have been told they are very hard to eradicate. Would you please give us directions on how to best get them "gone". One friend said to mow them down first, then try to eliminate them. Please let me know if this step is necessary, helpful or not helpful. Our gardening skills and knowledge are limited, sad to say!

Hello, I bought this aloe plant in February. It seemed to me that it was too big for the pot it was in and I separated it into three plants. I used cactus potting soil when I transplanted them and only water them every 3-4 weeks. The plants are now tall and thin, with semi-brown stalks and dehydrated leaves. They do not look well and would appreciate any advice on how to help them.

Hibiscus Gall Midge #147160

Asked 2013-08-14 19:50:25

I live in Houston and for a week or so, my hibiscus seem to produce only tiny buds which turn yellow and fall off.  I thought it was thrips until I read about the gall midge.  I have been picking the buds off so not to let them hit the ground.  I would prefer to use a natural predator if there is one, but if not, do you recommend a certain systemic to control them.  I have quite a few hibiscus and they all seem to be doing this.  In the picture the bottom bud is already turning yellow.  HELP!

While I'm asking, what do you recommend for thrips?

Thanks in advance for your time.

House Foundations and planting Hazelnut, Apple, Cherry and Grape #368668

My husband and I are thinking of planting an apple tree, cherry tree, grapes and hazelnuts in our yard but were wondering how far from the house they would need to be planted to prevent damage to the foundation and to overall promote healthy plant growth. I'm assuming variety will make a big difference and would appreciate recommendations on that front too. Thank you!

Italian Plum tree problems #248866

Asked 2015-06-01 20:50:09

Located on the NE side of Bend neat the Bend airport. Italian Plum Tree: Before signs of a problem. I treated the tree with a Systemic May 1. May 1st. I noticed the leafs curling and looking like the pic I attached. I sprayed the tree with Bonaide All-Seasons spray which contains Mineral oil as the active ingredient. May 23rd. I sprayed the Tree again with the same treatment. I also removed the worst sections of the tree branches that had the leafs curled. May 28th. I released 1000 lady bugs on the tree. With lady bug nectar sprayed on the tree. I have not noticed any improvement and the tree is getting worse. Is it bugs or something else? The tree does this every year. Each year, I try something different and nothing helps. I still get plums that are good to eat. but by late June, the leafs are getting spots, turning brown and falling off the tree. Tree gets plenty of water. I gave it a dose of magnesium spring of 2014. I also give it a fruit tree fertilizer spike every fall and spring.

killing crepe myrtle suckers #151982

Asked 2013-09-10 13:28:11

We had 2 large (>20' high) crepe myrtle trees cut down this spring and are now dealing with loads of suckers.  The roots were ground down about six inches by a commercial stump remover.  Now there are suckers everywhere.    No matter if I cut, dug or sprayed  with weed killers, or all three in combination to kill the suckers above ground,  even more come back in their place. Any suggestions would be greatly appreciated.

Asked 2015-04-18 18:48:15

Last fall, I transplanted some hostas into my partial shade backyard. Now as they are starting to come up, they seem to have sunk in the centers, maybe 2-4 inches deeper than the soil around them. Will I have problems if I leave the soil as it is and they grow with a sunken spot (holes average 4-7 inches in diameter). Would you advise that I add soil on top, or try to lift the plant and add soil under it, or clear away some of the ground around them, or just let them go?

mitigation of the allelopathic effects of winter rye as soon as possible #251590

Asked 2015-06-07 15:22:47

Love this access to expert info!
                            Just found out my winter rye which has seed heads is allelopathic in the short term.I have to get the vegetable garden planted soon.Should I yank it out roots and all and use it later for mulch or compost it.Is there some way to minimize the negative effect? Maybe put molasses and fish emulsion to get the microbes going.The garden isn't that big so at least on some of it, labor and costly efforts might be possible.Are there some vegetables less affected.Would transplants grow better than seeds.
                                   Also I would like to increase the worm population in the raised beds{all of the grden is raised beds}.I was going to use coco coir or soil pep {a type of fine pine bark}.Would something else be better for worms.Half the Garden is right up on the front side walk, so it would be better if it looked good.Thanks in advance. If you can only answer 1 question the first one about the rye is most pressing.
Thanks,Jon Valenzuela
