- 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!

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!

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, itâs 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, Iâd 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!

Lawn options-seed or sod
-
Date Posted: Wed, Aug 18 - 2:00 pm
- Iâm trying to decide what to do about my front lawn. Itâs a little under 60 square yards. Everything is killed off and tarps are covering the ground now to keep weeds from growing. There is no shade, all day sun. I would like to know if Tall Fescue is the best choice and also should I seed or sod. Cost is not the issue since itâs a small area. I hope you can give me some advice.
- Well, I know you didnât ask this but what about foregoing a lawn and planting a dooryard garden instead?. Iâm not much of a grass person. A patch of clover is more to my liking, at least it gives the honey bees a place to land, adds some nitrogen to the soil. Maybe a combination of a lovely shrub border, a small tree, a mix of tall and low-growing perennials, groundcovers? Since it's a small area the expense wouldnât be staggering and you can always phase in the plantings. Something to consider.... That being said, I think youâre doing a good job of preparing for a fall planting by covering the space and killing off the weeds. If I haven't persuaded you to take a different approach, Iâll try to answer your question about seed or sod. You didn't mention why your lawn was "killed off". Is there an issue with the soil? If so, you should request a soil test kit from the Richmond VA Cooperative Extension Main Office: (804) 786-4150. The results will let you know what, if any, amendments you'll need to add. I think the choice of a tall fescue is fine and fall is a good time to start a cool-season grass. When purchasing seed, check the bag to make sure you are buying all seed and no filler. Look for the two Virginia-Maryland labels affixed to the package so you know you are buying seed mixtures or blends which comply with the quality standards of the Extension Divisions of Virginia Tech and U of MD. First, you'll need to prep the soil. Remove all the dead weeds you've killed by covering and make sure there are no roots left in the ground. This can be tedious but it will pay off in the long run. Work in any amendments your soil test dictates. Add a layer of compost, you can till it in, or if your soil isn't compacted, adding 1-2 inches to the surface should suffice. Grade the soil with a rake so the surface is smooth and uniform. At this point you can seed. Disburse the seed with a spreader and go back and forth across the lawn, then in a perpendicular direction, attempting to get an even amount of seed across the surface of the lawn. You can add another fine layer of compost so that there is good contact between the seed and soil. (For a larger lawn you would roll the seed at this point.) Then you'll need to water immediately thereafter and continue to water until the seed germinates. (Be careful when watering, keep the soil moist, don't wash the seed away.) After that a total of 1-2 inches of water a week should keep the grass in good spirits. Hand pull weeds. An established lawn could take up to 2 years with seed. If this doesn't sound like fun, you can clean up the soil as above, amend as needed, grade it with a rake, and lay sod. Do not let the sod dry out. You'll need to water the sod daily for a couple of weeks (of course, less if there's rain). During this period the sod will be putting down shallow roots into your soil bed. Avoid walking on the sod during this period. After about a month the sod will have established a better root system. Around this time it will need to be mowed. Set the mower to 3 inches. The sod will provide a quicker route to a nice green lawn if the expense is acceptable. I hope I've covered all your options. Good luck with the project!

August Beauty Gardenia
-
Date Posted: Wed, Aug 18 - 1:59 pm
- I have purchased an August Beauty Gardenia shrub and would like to give it the best chance to thrive in my yard. Would it be better to plant it in a spot with the most sun (also near the house), yet fairly exposed as no other plantings near, or in a bed which gets a good amount of sun and has established hedge (hollies) which may offer protection from the elements? Thank you in advance for your help.
- What a beautiful plant selection! Youâll enjoy the long blooming season of this plant, and of course their wonderful fragrance. In terms of best location, you should keep two things in mind. First, to ensure a prolific bloom all summer, you want to maximize early day sun exposure. If one of your described locations is on the east side of your yard and gets several hours of early day sun, that would be ideal, especially near a walkway or porch where you would enjoy the fragrance. I would try to avoid a location that is fully exposed to our late afternoon hot sun during July/August. Secondly, consider your soil and drainage in selecting your location. Gardenias like evenly moist acidic soil which provides good drainage. You want to avoid planting your gardenia where its roots would compete for moisture with nearby trees. The bed with hedge hollies would be fine if you have several hours of early day sun there. If you are planting your new gardenia this time of year, be sure and add plenty of organic matter to your soil, mulch around your plant, and provide plenty of water during this last phase of summer. Enjoy your beautiful plant, and let us know if further questions!

Eradicating Giant Taro
-
Date Posted: Wed, Aug 18 - 1:43 pm
- Continuing along the theme of invasive species, we have several clumps of elephant ears (giant taro) in our yard that we are trying to eradicate. We have dug them up twice already and they keep coming back. Any tips or solutions that can rid of us of this invasive plant? Thank you very much.
- Good morning, and thank you for your question! Giant Taro (elephant ear) are dramatic and beautiful to admire, but we know they can be problematic spreaders. This invasive plant is typically hardy only in zones 8-11, but with our recent mild winters here in zone 7, they easily thrive. They are best planted in very large pots in the garden or on the patio, where they can be contained and enjoyed without the spread. The best organic approach for removal and eradication of elephant ear in the garden is to simply dig them up (and likely repeatedly), until they are all gone. It sounds like youâve taken this approach twice and theyâve come back. Be sure and dig wide and deep enough to remove all small pieces of the corms (tubers), and dispose of them in a plastic garbage bag. These small pieces can colonize and form new plants if left in the ground. Remove the soil in the area and replace it as well. As youâve learned, this often requires repetition until they are all gone. If any new growth emerges during the fall, repeat the process, cutting down all growth to 1â above the ground and dig up the tubers and all small corm pieces in the ground before winter. I wish I had more magic tricks for you to try to solve this. Perhaps weâll have a colder winter this year (more in line with our climate zone) which will help as well. Good luck!
