Native plants
-
Date Posted: Thu, Sep 15 - 9:44 pm
- 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?
- 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!

Fall garden planting
-
Date Posted: Tue, Sep 06 - 9:28 pm
- Hello! I just moved to RVA and Id like to plant a small flower garden in front of my house. The area receives sun most of the day. What plants could I plant that would adjust to being planted in September? Thank you so much! Taylor
- Hello Taylor! You've got two really good things going for you-sun and fall planting. Fall is a great time to plant here, though you may want to wait until it cools down just a little bit. This will give you some time to mull over your design. Your plant palette is pretty much wide open. Richmond is on the border of the piedmont and coastal plain regions, so you can use plants that are native to either of those areas. To get you started I have a few plant suggestions. They are: yellow coreopsis (tickseed), some purple echinacea (purple coneflower), liatris (liatris spicata)-also purple, orange butterfly weed (asclepias tuberosa) not butterfly bush, one of the native low-growing phloxes-divaricata or stolonifera, maybe some little bluestem grass (schizachyrium scoparium) for a different texture, for some height-oxeye (heliopsis helianthoides) and some shrubby st. john's wort (hypericum prolificum) for its lovely pollen-laded flowers and attractive foliage. One of the best approaches is to find a nursery you like that sells native flowers and see what is for sale at the nursery as the months pass. Ask the staff for information, they love sharing their knowledge! I also suggest reading up on what is, and why plant, a native plant. This is a really useful website--https://static1.squarespace.com/static/58e25c41e6f2e17ea4cb7766/t/5ed00bfcb208c2251311ebc6/1590692887078/Native+Plants+for+Virginia%27s+Capital+Region+Guide+for+download.pdf. Check out the information for the capital region on this website when gardening in Richmond but remember you may be able to use some plants for the coastal plain as well. Before starting your garden it's a good idea to get your soil tested to find out if it's lacking in any nutrients. You can find out about cost and how to gather a good sample by calling to speak with a VCE-MG at our Chesterfield Master Gardener Help Desk weekdays during regular business hours, March through October or call (804) 751-4401 to speak with the Master Gardener on call. Also, the local branch libraries have MG help desks. Check your local branch for the day and time and speak to an MG. They are there to help! Best of luck with your new garden!

- where can I find a list of native flowers to plant as well as native seeds to plant in my garden. I am aiming to increasing visits from pollinators! My space gets about 6 hours of full sun. Thanks!
- Hello there, so glad you are thinking about all the benefits of native plants. Not only will you attract pollinators but you'll increase the food supply for birds and beef up the organisms in the soil working underground; just to name a few benefits. I'm attaching 3 different websites that are wonderful references, the one for Virginia natives is especially useful. There is no shortage of choices. Internet resources: www.vpns.org; www.xerces.org; www.plantvirginianatives.org. Have fun planting your new garden!! We all appreciate it.

Pests and diseases

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

Pollinators

Date Posted: Sat, Mar 26 - 12:31 am
- What can I do to keep white butterflies from my garden plants that need pollinators, such as squash.
- Hello there, The white butterflies you're referring to, are those active now in your garden? If so, those are cabbage white butterflies. The larvae of those butterflies tend to feed on cabbage, collards, kale and some other greens (Brassica family of plants). If you want to keep them away from these crops, fine netting is your best bet. The butterflies lay eggs underneath the host plant's leaves. The larvae are caterpillars whose coloring closely matches the host plant. They are voracious eaters so it's good to check the plants under the net to be sure none have escaped your notice. If you're looking to be sure to have pollinators for your squash plants be sure to plant a variety of herbs, flowers, shrubs and trees in your yard. Using native flowers and shrubs will provide pollen and nectar. Native shrubs and trees also provide shelter and nesting materials for bees and other beneficial insects. A variety of flower color and shape will attract a wider variety of pollinators. I hope I have answered your question. if not, please reach out again. Best of luck with your garden.

Low-maintenance ground cover

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

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!

Watering roses
-
Date Posted: Wed, Aug 18 - 1:48 pm
- Hi i have a row of drift roses on the front on my yard, they are in full sun. I had been watering them every other day with the lawn but noticed that a few bushes had yellowing leaves which then turned brown and crispy. I am assuming that is a sign of being overwatered? Any suggestions on how to make the flowers last so they don’t turn brown so quickly in the heat? Thanks!
- Hello there, My first instinct is that you are, in fact, over watering your roses. How long have the roses been planted? If it's been a few years then watering once or twice a week should be sufficient. Is the soil well draining? Roses don't want to sit in consistently wet soil. Are you able to gauge how much water, in inches, your roses are receiving. one to 2 inches of water (rain+water combined) should keep them healthy. I believe that's about 4-5 gallons of water a week. Also, I don't think the heat is causing the roses to brown but the effects of over watering are. Back off on the watering a bit. Try to avoid the foliage and water the soil around the plants and see that they get soaked rather than sprinkled. I suspect that less water weekly (avoiding the foliage whenever possible) and a couple of good soaks a week will make you and your roses happier. Good luck!

Yellowing Aster
-
Date Posted: Wed, Aug 18 - 1:46 pm
- Hi we have a row of fall aster and notice that this year and last as the rest of the plant grows large and bushy the base starts to get yellow and then dries. the plant seems to be getting enough water. Is this normal?
- Good morning, and thank you for your question! My first thought is that you may have a watering issue. I’m assuming your aster plants otherwise have normal growth, are not stunted, and bloom well. Asters do prefer well-draining soil and like to keep well watered. However, they do not like overhead watering or sprinkling. Doing so can result in development of a fungal disease. Watering should be done at the base of the plant where fungus would first develop. It also helps to use a good organic mulch around your aster plants to help retain moisture and prevent splash to the lower leaves which can cause the yellowing. As a side note, be on the lookout for leafhoppers on your aster. They can spread bacterial disease (phytoplasma), which is a more serious problem to deal with, but with this you would likely notice other symptoms such as stunted growth and deformed flowers as well. If those symptoms develop, the plants would need to be removed as there is no cure. It does not sound like you are experiencing these specific problems with your aster, and proper watering and mulching would be the best first steps to implement. Good luck with this, and let us know if further symptoms develop.

Shasta Daisy-browning, die back
-
Date Posted: Tue, Aug 17 - 8:52 pm
- 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.
- 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! "
