Pollinator gardens

    Date Posted: Wed, Sep 28 - 11:26 pm

    Question

  • Thank you for your quick response! The after school program supports 24 students (12 second graders, 12 third graders). We will be researching and designing the gardens from October until December. The program runs until the end of the year, so we can build it next spring or late fall - whichever best meets your schedule. The principal is allowing us to build it in the area where a previous garden was built a few years ago. I believe it will be roughly 5' by 5'. Do you have anyone that might be interested in discussing gardening or butterflies with the students? The presentation can be virtual or in person. Thank you again for your assistance.
  • Answer

  • Thank you, this is very helpful. It sounds like a great program! I'll be passing this along to others and will post it as a volunteer opportunity for those to help build and instruct. Please send me all your contact information to this address--jrreilly2323@gmail.com and we can discuss more specifics. We look forward to working with you!

Native plants

    Date Posted: Thu, Sep 15 - 9:44 pm

    Question

  • I have an east-facing front yard in the Museum District and have approximately 12X 6 feet of space to work with. We recently got a retaining wall put in, and so it is a fresh canvas. The space gets full sun at least half the day. I love native plants, and particularly those that would remain evergreen in the winter. Any suggestions?
  • Answer

  • Hello there, so nice to start fresh! I'm glad to hear you are interested in using native plants. I'm assuming the space is 12 feet wide and 6 feet deep. You'll probably want to start by creating some structure with shrubs. For evergreen green shrubs you could use inkberry (ilex glabra). There are many varieties of this plant, some have a loose form whiele others have a tighter globe shape and there are large and smaller sizes as well. So there's an inkberry to fit most spaces and styles. Mountain laurel is also another lovely evergreen plant with beautiful blooms in spring. Dog hobble or more commonly just Leucothoe (axillaris) is another nice evergreen. There is a variegated variety if you want to brighten up a space. You may also want to try evergreen bayberry (morella caroliniensis). In addition to these evergreens, there is virginia sweetspire (itea virginica) which has a nice drape to its shape, panicles of white flowers and beautiful fall color. Another good shrub is pepperbush (clethra alnifolia) with white to pink flowers (depending on variety) which is wonderfully fragrant. There is a smaller-sized variety that would fit in most gardens. Many of the plants in the blueberry family - early lowbush and deerberry (vaccinum pallida+vaccinum stamineum) have gorgeous fall color and colored bare stems in winter. Their spring flowers are delicate and beautiful and their fruits add to their appeal. I know you have a small space but I wanted to give a good number of options so you can pick and choose. Once you have a plan, you can decide what you want to place where. After placing the shrubs, you can then think about adding some lovely native ferns, perennials and/or ground cover, whatever space will allow. Before deciding on plants and placement, you should have a soil test done if you haven't already. You can amend if necessary and as an annual ritual, add compost to nourish you plantings. You can get a soil test kit at your local library when the Master Gardener Help Desk is in operation. Call your local library to find out the day and time. For additional information I suggest checking out this website and using the plant guides for the Capital region and NOVA-- https://www.plantvirginianatives.org/plant-rva-natives. Best of luck with the new garden!

Pests and diseases

    Date Posted: Mon, Apr 11 - 6:11 pm

    Question

  • Hi there, We just moved into our home last fall and I’m just getting into gardening. I have a few issues I’d love some help with, namely, treating leaf diseases on a young azalea with freeze damaged buds, a large overgrown camellia with what I think is tea scale and flower blight, and leaf spots on mophead hydrangeas. There’s so much information out there but would love help identifying these issues correctly and providing timely care while we’re still in early Spring. Thank you! Emily
  • Answer

  • Hello Emily, Good to hear you've inherited a nice garden. There is always a learning curve with a new garden. I think the best way to answer your questions is by using the Plant Disease Clinic. The Richmond VCE office is closed until a new agent is in place. In the meantime, the Chesterfield office is generously offering this service. The clinic does charge a fee of $35 for samples. I'm including a link to their office so you contact them directly for instructions on the process-- vce@chesterfield.gov Best of luck and happy gardening!

Low-maintenance ground cover

    Date Posted: Wed, Mar 16 - 4:44 pm

    Question

  • Do you have any suggestions for low maintenance, year-round plants to fill a small area (6ft x 2.5ft, not much depth) on a steep 45-degree hill in partial sun? Ivy was previously growing here but we are looking for a change. Thanks!
  • Answer

  • Hello there, Good idea to get rid of the ivy!!! Since you're dealing with a slope you'll need a plant that's useful for erosion control. The first one that comes to mind is fragrant ash. It's a native low-growing shrub that colonizes a space so you won't need many plants to fill the area you have. The cultivar Gro-Low is about 2 ft high. Yellow-green flowers appear before the leaves in spring. The female plants have fuzzy red berries and the plant provides cover for birds and small mammals. It has excellent fall color, can take sun to shade and is fairly tolerant of most soils. While this is a fairly low-maintenance plant, all plants need appropriate amounts of water as they settle in for the first year or so. Best of luck with this change!

Strawberries Varieties for Richmond

    Date Posted: Sun, Feb 13 - 9:09 pm

    Question

  • What are the best varietals of strawberries to grow in RVA?
  • Answer

  • Hello there, Glad to see that you are thinking Spring! You have a number of choices for this area. There are several types of strawberries: June-bearing, day neutral and ever-bearing. I believe you'll be most successful planting the June-bearing varieties here. The other two options are more suitable for cooler climates. Some basic requirements for fruiting are to make sure you're planting an area that gets full sun (usually 6-8 hours a day), most likely near to your vegetable garden. However, do not plant in sites where tomato, potato or eggplant were previously planted to keep down disease (verticillium wilt and some others). Be aware that strawberries will reproduce quickly, this can be both a pro and con depending on how much space you have. Clip the runners if you are most interested in having larger berries on the mother plant. It's often suggested that strawberries can be integrated into an ornamental garden but I've never had very good luck with that approach but feel free to experiment. They could make a nice ground cover in the right setting. Some recommended varieties from VA Tech are: June Bearing--Sweet Charlie, Camino Real, FlavorFest. Of course there is always our native strawberry from which many cultivars are produced--fragraria virginiana. If you would like more information on this subject, I've attached a link. https://ext.vt.edu/content/dam/ext_vt_edu/topics/agriculture/commercial-horticulture/small-fruit/fruits-in-the-home-garden.pdf. Best of luck with the berries!

Overwintering Geraniums

    Date Posted: Thu, Nov 04 - 8:07 pm

    Question

  • I have a geranium that was brought indoors a few days ago and still has blooms. How to I store it in the winter months? I heard you can cover it with a plastic bag and keep it in a dark, cool place - ie. garage. Is that Ok? Does it need to be watered? Thanks, Lori Pettit
  • Answer

  • Hello Lori, You have a couple of options for your geranium. The first would be simply keep it indoors as a house plant assuming you have enough window space/light. Another option would be to unpot the plant, shake off as much soil as possible, and store the plant in a paper bag in a darkened cool space. Ideally, the temperature would range in the 45-55 degree area. A garage could work if you manage to keep the temperature at that range. I prefer the first method because you get to enjoy the plant all winter. There's also less chance you'll forget about it next spring!! It will most likely go through a transition phase and you may lose a few leaves but with enough sun it should continue to bloom (probably somewhat less) all winter and into early spring. If the geranium is very large and will possibly take up too much space inside, feel free to cut it back to about 8 inches. It will spend the winter putting on some more growth. As the temperature warms in spring you can start introducing it back to the great outdoors. Somewhere around mid-April (after the last frost) move it to a shady spot for a few days so it can acclimate and then move it to your preferred place. Good luck with this process!

Squash Bug Control

    Date Posted: Sun, Aug 22 - 3:10 pm

    Question

  • 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!
  • Answer

  • 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!

Shasta Daisy-browning, die back

    Date Posted: Tue, Aug 17 - 8:52 pm

    Question

  • I have a large shasta daisy that I planted along my side yard years ago. About 3 years ago it started having "issues". It starts the spring with very green and abundant stems/leaves. And everything seems wonderful as the plant starts to bud....but then the flowers bloom already browning and die quickly. I am guessing it has some kind of wilt but not sure what to do. I also have dianthus in pots up my steps for the first time and it appeared that they also caught "the wilt" but they seem to be bouncing back. Not so for my Shasta daisies. Is there anything I can spray them with or can I transplant? It's such a gorgeous prolific plant.
  • Answer

  • Sorry to hear of your daisy troubles. I'm going to refer to a previous answer I gave about Rudbeckia 'Goldsturm'. The daisies are also one of the stalwarts of the garden but can run into various problems. Please see the rudbeckia answer below. I didn't spell it out in the answer below but good drainage and air circulation are essential for plant growth and prevention of fungal diseases. And again, if your plants continue to succumb, selection of a new plant for your particular environment may be a good solution. Good luck, let us know your progress! "Rudbeckias are usually pretty sturdy plants but they do succumb to some fungal issues. Sometimes the problem could be attributed to too much water, so that's a simple fix. Or, you may be dealing with septoria leaf spot or a similar fungus. Rain and humidity contribute to the problem. You can start with some cultural practices. Remove all affected leaves and put them in the trash. The fungus overwinters in infected plant debris so you want to clean up the area around the plants to make them less inviting to the fungus. You may also try moving the plants to a spot with new soil and seeing if the plants improve over time. Additionally, do not water from overhead. Try a soaker hose so that the foliage does not get wet. You could also try a baking soda solution spray but that's usually better at prevention. A neem oil solution may be effective. You may decide to simply remove them from the garden and substitute another perennial that's less susceptible. There are many choices. A lot of gardening is just adapting to your circumstances and trying new plants that may be better suited to your patch of ground. Best of luck with your garden! "

Japanese Holly Dieback

    Date Posted: Tue, Aug 17 - 8:37 pm

    Question

  • There is a hedge at the front of my property. Someone years ago told me they are Japanese hollies. I found a tag on a bush in the back yard which I believe is the same plant--it's Ilex crenata 'Bennett's Compacta'. They had been very healthy and growing almost too well for nearly 12 years until this spring when one bush turned brown in a matter of days. I cut out all the brown and there is some new growth near the base, but I have 2 questions; 1. What are likely causes of the die-back? 2. What are the chances that this will affect the other bushes? Since it's the front of the property it's already unsightly--looks like a missing tooth--but I don't want to replace the one diseased bush in the row if they could all be in jeopardy. Thanks for your help. Shelley
  • Answer

  • Hello there, Without seeing the plant and the place it's situated, my best guess about the origin of the dieback is black root rot. I am attaching a link here from Virginia Tech with an information sheet. It's a tough problem. If you believe that's why your shrub succumbed and since the hedge has served you well for 12 years, it may be time to replace it. Of course, any replacement would have to be a variety that will not be susceptible to this root rot. Let us know if you have further questions. Best of luck.

Recommendations for spring vegetables in garden box

    Date Posted: Tue, Aug 17 - 8:33 pm

    Question

  • We have two garden boxes planted with a variety of spring vegetables. I'd like to add a new box or two this week, but worry I've missed the planting window. Any recommendations for plants that would do well starting in June?
  • Answer

  • Thanks for your question. It’s definitely not too late to plant for some vegetable varieties. Several good options include carrots, beets, radishes, as well as peppers and tomatoes. Chard is also an option. Carrots, beets, and radishes can be planted every 2 weeks until mid-summer for continual harvest (depending on size of your garden boxes). Tomatoes and peppers generally take approximately 60 days to maturity - check the labels on the varieties for maturity time. Chard can be seed planted until mid-summer in our zone (zone 7). Hope this helps, and let us know if further questions!
