- Instructions for moving English boxwood
- Hello there, This is the right time to be thinking about moving plants though I wouldn't actually move it until we hit a spell of cooler weather. I happened upon a useful link that describes the process better than I could. The link is from the magazine Southern Living and includes photos. https://www.southernliving.com/garden/grumpy-gardener/transplanting-b It looks like a good guide. Best of luck.

Master plan-ADA compliant gardens
-
Date Posted: Sun, Sep 05 - 9:31 pm
- Hello, I am moving from London to Richmond. While I have won awards for garden design, now, I am a handicapped senior. I want a parterre, which is ADA compliant, and am looking for a master gardener to help create. Whole property is 4 acres, 2 lawn, full sun. Where would I find master gardeners around Richmond who know best plants/roses/ilex for the region. Also, any other ADA gardens? Thank you.
- Hello there and welcome to Richmond! Your project sounds intriguing though outside of the work typically done by Master Gardeners in Richmond. It seems you are looking for a master plan of your new property to include hardscape and gardens for a 4 acre property. Master Gardeners work to educate and work with the public on community projects. You may want to check in with the Virginia Society of Landscape Designers--www.vsld.org. Their website will connect you with designers and there are lots of photos from various designers to aid in making a choice. I can't say I know of any ADA compliant gardens myself but I have reached out to another organization to see if they have information that would be useful for you. I will let you know what I find. In the meantime it would be helpful to research the zone you will be living in to see if the plants you have in mind will thrive in your new landscape. The zones for Richmond are 6b to 7a. And sometimes micro-climates provide a situation for plants outside these zones. Please send me another message as a check in so I will be able to give you an update. Allow some time for the other organization to get back to me. Best of luck with this project, It's very exciting!

invasives

Date Posted: Fri, Aug 27 - 3:36 pm
- 1) I have rampant overgrowth of wisteria, as well as more limited poison oak in an area covered by pine straw, ornamentals on perimeter of area, but worst parts are distant from these bushes. 2) Also widespread seeding from a mimosa (since cut down, but too late) throughout the front lawn. I'm averse to using Round-Up, and wonder if you can offer solutions and guidance. Many thanks! Catherine Davis
- Hello there, There's a lot do here. The wisteria should probably be dug up and put in the trash. They are rampant vines. I have seen some people do an excellent job of training them and keeping them in bounds. It all depends on your maintenance tolerance. If they are left to run wild they will climb trees and kill them over time. The poison oak (which I think is actually native but no one actually wants it in their yard) should probably be smothered. I understand you not wanting to using Round-up or a similar product, I wouldn't use it either. If they are young and small plants depriving them of sunlight, water and nutrients will over time kill them off. It could take several months but doing it now with this hot weather will help the soil heat up to kill the plants. Tarps, cardboard, plastic sheeting, these should all work. This process works best in sunny sites, you didn't mention the exposure. I've also had success using straight white vinegar on any plants that survive and re-sprout. And of course, be sure to wear protective clothing, head to foot, any time you are working with poison oak or ivy and put the clothes in your waster with hot water when you're done. As far as the mimosa seedlings, I can only imagine hand pulling them. I don't know the area in question but using vinegar in your lawn will damage the grass and I'm sure you don't want that. Hand pulling is one of the most effective methods to use when possible because you can often get the root of the plant out. Having a good thick ground cover is the best bet for keeping out all those unwanted plants. If there's a vacancy, they'll occupy it!! Best of luck Catherine!!

Squash Vine Borers
-
Date Posted: Tue, Aug 24 - 1:57 am
- Hi there! Thank you so much for doing this! I have a couple questions on squash vine borers, which have been a HUGE issue in my garden this year. I have been surgically removing the larvae from my curcurbit vines every few days for over two months now (along the way losing both of my zucchini plants and one patty pan squash plant; now I have one patty pan and 4 pumpkin plants remaining). My questions are: How much longer should I expect new larvae to bore into my plants? And is there anything I can do next season to organically prevent these pests (or perhaps control them in a less laborious fashion!)?
- Hello! Thank you for your question. It sounds like you have had a challenging season with this difficult pest. Your surgical removal of the larvae is one part of the solution, and it sounds like you have mastered that particular process. There are other things you can do as well. To answer your first question, it is important to understand the lifecycle of the squash vine borer. Eggs will first appear in our area in May, will hatch in early summer, and then the larvae will bore into the squash stem to feed for up to 4 weeks. When the larvae are mature at 4-6 weeks, they will leave the vine and the dig 1-2 inches in the soil to pupate. In our climate, we can sometimes have 2 generations of larvae in a season. So unfortunately, once infested, this pest can present a problem for most of the growing season. In addition to the surgical removal process of the larvae in the stems, you can also use an organically approved insecticide such as Spinosad or Bacillus thuringiensis (Bt). Apply the product on the leaf stems and the main stem of the plant - do not spray the flowers. Apply one of these insecticides once per week during the growing season. It will kill the borer's eggs and larvae quickly. Again, these are organically approved products, and we recommend staying away from any synthetic, non-organic insecticides. Another method for prevention early in the season is to cover the young plants with a floating row cover until flowering occurs. The row cover will keep out the insect in the critical early part of the season, and will still allow sun, water, and air to get to the plant. Once flowering begins, remove the cover to ensure pollination is not disrupted. If or when you do have an infected vine(s), seal them in a plastic bag before the larvae pupate. This will break the lifecycle of the squash vine borer. And finally, the other important practice is to till under all crop debris after harvest, which also disrupts larvae in the soil, and prevents buildup of the squash borer population. Implementation of these practices should minimize the need for constant surgical removal of the larvae, and yield healthier plants and better crop. Good luck, and please reach out with any other questions!

Squash Bug Control
-
Date Posted: Sun, Aug 22 - 3:10 pm
- I have been having a hard year with squash bugs taking over my zucchini plants. I am wondering if you have any tips on how to prepare the soil this winter to decrease their activity next season. Thank you!
- Good morning! Thank you for your question. You are certainly a step ahead in that you have identified the pest, and have probably read about effective means to control and hopefully rid many of the insects during the growing season. Nevertheless, they are difficult to eradicate. You are smart to be thinking about ways to overwinter the garden to minimize the problem next spring. Do you use mulch around your zucchini plants? Mulches give adult squash bugs a place to overwinter, and you want to remove that mulch if you have used it. Straw is a better alternative to use around these plants in the growing season. As fall/winter approaches, you want to be sure and clean your garden of old vines, crop, and leaf debris where adult bugs will hide over the winter. Squash bugs will rarely survive cold winters without places to hide. However, Richmond has been known to have very mild winters, and you surely don't want to give these bugs a place to hide. Once you have removed all debris (and mulch, if you have it), till the soil. This also helps eliminate the pests. If you have the room in your garden (which most city properties do not), it is also helpful to rotate your crops year to year to keep down insect population. But the best thing to do is completely clear the garden of all debris for the winter, and till the soil. One tip for next spring/summer, is to place boards or old shingles on the ground next to the garden (especially at night time). Squash bugs love to hide under these, and they make excellent traps for collecting the bugs in the morning, and then placing the bugs in a bucket of soapy water. And of course, regular inspection during the early growing season to collect these bugs from your plants helps as well. But definitely follow the guidelines for garden cleanup and tilling to properly overwinter, and that will certainly get you off to a clean start in the spring!

Sod died-alternative
-
Date Posted: Wed, Aug 18 - 2:07 pm
- We have a very small 200sf area in the front of the house that was previously sod. That grass has died this summer (we think from a fungus) and we are thinking about doing something lower maintenance like a moss. Any recommendations or thoughts on that? The yard is am sun, north east facing, good drainage. Thanks!
- Hello there! Since your sod failed it would be worthwhile to have your soil tested. You can request a soil testing kit from the local extension office-the phone number for Richmond City is (804) 786-4150. You can check this link for the process: https://www.soiltest.vt.edu/sampling-insttructions.html. Also ask about the whether the demise of your sod was most likely due to incorrect ph or a fungus. Once you've established your soil's ph (whether it's an alkaline or acidic soil) you'll be able to make informed decisions about what plants to use. If you want to use moss, you'll need soil on the acidic side-5.5. I've included a link about mosses in lawns and how to grow a moss garden. Skip to the section entitled "Moss Gardens" for pertinent information. Here's the link: https://www.pubs.ext.vt.edu/430/430-536/430-536.html You'll have to judge how much sun your space receives and whether or not that might be too much for mosses. In lieu of mosses, there are many alternative ground covers. I mentioned a number of them in the post Dog proof ground covers. Often a combination of them can be very pleasing and generally low maintenance. The addition of shrubs with some good mulch can also add interest with minimal upkeep. Enjoy the project!

Dog-proof ground cover
-
Date Posted: Wed, Aug 18 - 2:06 pm
- Hi! We have a small back yard (no trees) in the Museum District that faces southeast. It's mostly dirt and crabgrass. We also have two dogs. Can you recommend a good, tough, affordable, relatively "dog-proof" ground cover? Something relatively soft that will be okay for bare feet would be idea, if I'm not asking for too much. Thank you!
- Ok, we'll have to laser focus to meet the requirements. I think a planting of dutch clover might do the trick for you. You're probably familiar with it, it tends to pop up in lawns frequently. You're going to have to kill the crabgrass before you attempt anything else. I generally suggest covering the area with tarps, newspaper, and/or cardboard to smother the weeds. However, this process could take a couple of months and you want to plant the clover about 6 weeks before a frost. If your space is small you could remove the weeds by hand, that would be quicker. Throw the pulled weeds in the trash, you don't want weed seeds winding up in your new clean space. Till the earth you've just cleaned up and spread the seed! Next-water. The clover will sprout in about 2 weeks. You'll need to keep the seed bed moist. Once the clover goes through a winter it will be established. Then you want to weed whack or mow the clover once a month when it's actively growing to keep the planting nice and thick. This choice would be the most cost-effective way to establish a walkable ground cover. An added benefit of clover is that is adds nitrogen to your soil. Of course, there are many other interesting choices for a sunny ground cover. You might want to experiment adding other plants and creating a bit of embroidery. There's always scotch or irish moss, mazus, ajuga, speedwell, or even creeping thyme, to name just a few other possibilities. Good luck with the project!

City Tree Removal in Front of House
-
Date Posted: Wed, Aug 18 - 2:05 pm
- The city recently removed a large elm from the sidewalk area in front of our house (3200 block of Grove Ave). Do you know if we are allowed to plant in that space? If so, what would you recommend? Thank you!
- Good afternoon! Thank you for your question. I had to do a little research on this one, as I have never experienced this at my property. Fortunately, the city addresses this on their Public Works website, where they provide information on their Urban Forestry program (I provided the web link below). This website provides information about the Municipal Tree Policy Ordinance. Under that section, you will see a list of Forms. There is a Form called Application for a Street Tree Planting Permit. I have included that link as well. You will need to download that form and submit it to the City for approval to plant a tree. The City typically plants elm trees or maple trees, and either would be a good choice. It appears from the Application Form that a city staff arborist must approve your species selection before planting. You may also want to contact the City to see if they have plans to replace that tree, before you go to the expense of planting one yourself. But if they do have plans to replace it, it may be a while before they would get to it. If you're like me, you'll want to go ahead with a replacement this fall which is the best time of year to plant new trees. But be sure and complete/submit the application in the link below, and hopefully a City staff arborist will contact you soon. http://www.richmondgov.com/PublicWorks/UrbanForestry.aspx. http://www.richmondgov.com/PublicWorks/forms/applicationNewStreetTreePlanting.pdfa.

Yellow Spots on Rhododendron Leaves
-
Date Posted: Wed, Aug 18 - 2:01 pm
- My large rhododendrons have some yellow specked leaves. Been watering every other day. What are you suggestions
- Hello! Thanks for your question. Given our recent warm and humid weather conditions, the problem you are having with your rhododendron is certainly not uncommon. I suspect your plant has a fungal condition called leaf septoria (yellow leaf spot). It sounds as though the condition on your plants is not widespread at this point and there are a few steps you should take to rid your plants of this fungus. First, remove the affected leaves to get rid of as many fungal spores as possible. Secondly, take away any fallen leaves from under the plant and keep the area clean. Discard all removed leaves in the trash (not compost). Mulch the area under your rhododendrons; this helps prevent spores from spreading. It will also help retain/absorb the water when you are watering the plants, and reduce splash upwards. And when you water, it’s best to use a soaker hose at the base of your plants, versus overhead watering. Watering overhead and watering in the evening can increase fungal disease development on these plants. You can also apply a simple, all natural spray solution consisting of the following: one quart of water in spray bottle with 1 teaspoon of baking soda; add 1/2 teaspoon of canola oil and a few drops of dish soap; shake the solution well and spray on the plants. Good luck with this - improved weather conditions in the coming weeks hopefully will help as well! Let us know if you have further questions. Thanks! And of course keep a close eye on your other grow bags with your other vegetables for any similar signs. Good luck with your garden, and wishing you a strong yield!

Worms/Caterpillars in Grow Bags w/Vegetable Plants
-
Date Posted: Wed, Aug 18 - 2:00 pm
- Like many in the midwest, I have started a victory garden of sorts over the past few months, mostly in large grow bags on a pallet on my deck. This morning I noticed that the grow bag containing my romaine lettuce was full of either some very freaky worms or caterpillars, and while the worms seemed to be contained to the romaine bag, I worry for my adjacent chard, collard greens, and tomato bags. After a quick google search, I discovered two options that I was interested in: bacillus thuringiensis or diatomaceous earth, but I would like to know what option would be the most efficient in terms of use of product and frequency of applications and also the most environmentally friendly. If there is a better option than those two, I would be happy to learn also. Thank you!
- Good afternoon! Thank you for your question. My first thought when I read your question is that the solution certainly depends on the type of worm or caterpillar-like creature in your grow bag. If you have common earthworms or red wigglers, I’d say leave them alone as they are beneficial to the quality of the soil and will benefit the overall health of your plants. But it sounds like you may have something different which could ultimately harm your plant. If, for example, you have cutworms (which resemble caterpillar) and/or leaf miner larvae in your soil, you want to remove these. First, I would separate the infested grow bag from your other grow bags which contain your other vegetables. I would then pick off the visible worms/caterpillars with your fingers and submerge them in a container of warm soapy water. Although the products you mention may be effective at killing the catepillar-like creature you have, they do have harmful attributes. They may be considered organic but they still have low levels of toxic ingredients to bees. I would use an insecticidal soap solution such as neem oil or simply mix 3 tablespoons of dish soap to 1 gallon of water and pour into your infected soil. Apply this process weekly. And if you see any of these caterpillars on the plant leaves, pick them off and spray the neem oil/soap solution directly onto the plant - repeat the process weekly. And of course keep a close eye on your other grow bags with your other vegetables for any similar signs. Good luck with your garden, and wishing you a strong yield!
