Arborvitae Decline
-
Date Posted: Thu, Feb 26 - 12:58 pm
- We have 2 arborvitae bushes/trees in our front yard. in Goochland County. One has died; the other is dying. They are about 25 years old. Perhaps they have just lived out their lives; but if there is something else it might be helpful to know before we replace them. We are only planting native plants now, so that might help the situation. If you have any thoughts, I would love it. Thanks so much in advance for all that you do for our community.
- Thank you so much for reaching out — and for your commitment to planting natives! That makes such a positive difference for our local ecosystem. Arborvitae can live quite a long time, often 40–150 years depending on the species and growing conditions, so 25 years would not typically be considered old age. When we see one arborvitae turn completely brown and another beginning to decline, it usually points to an environmental or site-related issue rather than natural lifespan. Is this a change that you have just been seeing recently? My first thought goes to the winter weather that we have had - both with all of the ice that we had sticking around forever in January and more recently all of the rain saturating our soils. Arborvitae do not tolerate prolonged saturated soils very well. When soils stay waterlogged, roots are deprived of oxygen and can begin to decline or develop root rot. The extended ice cover would have kept soils cold and saturated longer, further stressing the root system and delaying recovery. Evergreen foliage continues to lose moisture in winter, so if roots are compromised, browning can occur fairly quickly. It's typically not one single environmental factor that can lead to decline but several factors in combination: Wet soil weakens roots, ice delays recovery, a sudden warm spell increases transpiration, the plant cannot move water efficiently. That combination can lead to rapid browning. Spider Mites are also a possibility for the damage but seem much less likely to me. When spider mites are present, the foliage typically turns brown or dusty prior to becoming completely brown and you tend to see gradual thinning, rather than sudden death. It's also a little early to be seeing spider mites, but you could try shaking a branch over a piece of white paper to see if you see anything mite-like coming off. Given the wet winter and prolonged ice we've experienced, root stress from saturated soils is the most likely cause of the decline, particularly if one plant has browned uniformly and rapidly without visible insect evidence. While spider mites (and bagworms) can affect arborvitae, their damage patterns and seasonal timing do not match up with your description. Unfortunately, the one arborvitae that is completely brown is unlikely to recover, as they do not regenerate from old wood. The second tree may continue to decline if root damage has occurred. If you are looking for native replacement options, a couple of suggestions to consider are Eastern Red Cedar (Juniperus virginiana) and American Holly (Ilex opaca). Good luck! The arborvitae beautifully framed your porch and I know it must be disappointing to lose them!

Date Posted: Mon, Feb 02 - 10:37 pm
- I am a volunteer at Peter Paul Development Center in Church Hill. PPDC serves as an after school education program for student from public housing. I developed a 1,000 sf educational garden at PPDC. The garden program needs volunteers to help provide weekly maintenance and educational programing. It is great fun to expose the students to new vegetables and fruits, help them care for the plants, etc. Are there Master Gardeners who could help support the garden program?
- Thank you so much for reaching out to the Richmond Master Gardeners. Our group focuses on educational programming and I will reach out to our members to see if we have the capacity to add on a new project at this time. I will follow up with you via e-mail. Thanks again for thinking of us!

Improving Yard conditions

- How to thicken and greening a big yard with out reconstruction
- I apologize for the slow response to your question. I somehow did not receive the alert and just noticed the question when I was alerted to another question coming through. This is a question that needs more details for a specific response, however thickening and greening a large yard without major reconstruction is very possible, but the best approach depends on both site conditions and the end goal for the space. Before making changes, it helps to clarify whether the goal is a traditional turf lawn, a lower-maintenance landscape using native plants, or a mix of both. In general, improvements without reconstruction focus on soil health, plant selection, and management practices. Start with soil health (no digging required): Core aeration if the soil is compacted Top-dressing with compost to increase organic matter Soil testing to identify nutrient deficiencies or pH issues before fertilizing Next, match plants to both the site and the goal. If the goal is turf: Overseed with grass varieties suited to sun/shade, traffic, and moisture conditions. In Virginia, this often means tall fescue blends, fine fescues for shade, or warm-season grasses depending on location. If the goal is reduced turf: Transition difficult areas (deep shade, poor drainage, slopes, heavy traffic) to native groundcovers or mixed plantings. This can improve appearance and resilience without regrading or major removal And finally, adjust maintenance practices: Mow higher (3–4 inches for most cool-season grasses) Water deeply but infrequently Avoid over-fertilizing, which can lead to shallow roots and thinning turf Some information that would be needed to help give more specific recommendations would include sun exposure (full sun, part shade, deep shade), existing vegetation (grass type if known), size of the yard and problem areas, ultimate goal for the space (turf lawn, natives, or a combination), any recent soil test results. Feel free to follow up with us at rvamastergardeners@gmail.com. We also have some volunteers available for home consults and an in person conversation may be a great way to move forward! Thanks for reaching out to us and my apologies again for the delayed response!

Growing a Winter vegetable garden
-
Date Posted: Tue, Oct 28 - 10:21 am
- I have a raised garden bed, 4 ft by 8 ft, that is in a very sheltered location with good winter sunlight. I'd like to grow as much food as I can in that bed this winter. I'm open to adding a greenhouse cover of sorts if that would help, as well as mulching around the sides of the bed to keep the soil warm. what plants would you suggest?
- Thanks for reaching out to the Richmond Master Gardeners. It sounds like you’ve got a great setup for a productive winter garden — a raised bed with good winter sun and some shelter gives you lots of options, especially here in Richmond’s climate. With a little protection, you can keep fresh greens and roots growing all season long. We recommend focusing on cool-weather crops that tolerate frost and even improve in flavor after a chill. These include: Leafy greens: spinach, kale, collards, Swiss chard, mustard greens, and arugula Salad mixes: lettuce (especially cold-hardy romaine, butterhead, and oakleaf types), endive, and tatsoi. Root crops: carrots, beets, turnips, and radishes. Alliums: scallions and garlic (if not already planted, you can still get garlic in soon). Herbs: parsley, cilantro, and chives can survive with a little protection. A few tips to help extend your growing season: Since your bed gets good sunlight, a simple greenhouse cover or low tunnel can make a big difference. You can use PVC hoops and clear plastic sheeting to create a mini greenhouse, just be sure to open it during sunny days to prevent overheating. For added insulation, layer frost cloth (row cover) underneath the plastic on the coldest nights. You can also consider mulching the sides and soil with straw, shredded leaves, or pine needles to hold warmth and protect roots. Best of luck to you! I've also decided to grow some cool weather crops this year and have been really enjoying all of the greens my garden has been producing so far! We hope you have lots of success!

Master Gardener help in RPS
-
Date Posted: Thu, Oct 02 - 12:26 pm
- Hi, I'm looking for a master gardener able to volunteer between an hour to several hours to help Chimborazo Elementary School with its landscaping plan. Our PTA is currently engaged in a major clean-up of this Title I school and in fact just two weeks ago, 30 volunteers spent 5-6 hours cleaning, weeding and mulching just about an acre. There's so much more to do and once we're out of the clean-up phase, we will begin work on 1-, 3-, and 5-year plans to make this wonderful school and its neglected gardens shine. In the near-term, I am heading up the efforts to create these plans. I could use a master gardener to walk the grounds with me to identify a handful of plants I can't, discuss options for low-maintenance plantings, and other considerations we should be sure to keep in mind. We could also use someone to help us develop these plans but even one hour of volunteer time would be wonderful for us. Thank you so much for considering this request or connecting us with other master gardeners whom this might interest. We want to create a beautiful, thoughtful and interesting place for all of the children who attend this school.
- Hello! Thank you so much for reaching out to the Richmond Master Gardeners. This request is RIGHT up our ally! We have a meeting this coming Monday - I will get this request to the rest of our group and work to get you connected with a Master Gardener that has the availability to help with this project. I will be in touch via e-mail next week. Thank you!

Native Plants - best time to transplant
-
Date Posted: Wed, Sep 10 - 8:08 pm
- Hello! I have several native plants and two small elderberries that I need to transplant to different spots in my yard. Is there an ideal time to do this? I heard something about "fall" being a good time, but not sure when exactly that means? Thank you!
- Good afternoon! Thank you for your question. What you have heard is exactly correct - Fall is the best time to transplant your natives, as well as your two elderberries. I would recommend anytime in October when temperatures are cooler. Be sure and add some amendments to the soil such as a good leaf compost which can be purchased at a local garden center, and water the plants well after transplanting. Thanks for reaching out!

Declining Rose Bushes
-
Date Posted: Wed, Aug 20 - 12:18 am
- We have a row of drift roses out from for the last 8 years, last year once bush died totally after pruning and was replaced but two others appear to have dying branches in places but are blooming in others. Do you have any recommendations? They previously were huge and bloomed all summer.
- Thank you for reaching out about your drift roses. After 8 years, it’s not uncommon to see some decline in vigor, and the symptoms you’re describing (a bush dying after pruning, and others showing partial dieback while still blooming) may have several contributing factors. Possible Causes Age & Natural Decline: Drift roses, while hardy, often start to lose vigor after 7–10 years. Decline in individual plants can be expected over time. Pruning Stress: If roses are pruned too severely or at the wrong time (late fall/early winter), it can stress the plant and increase vulnerability to dieback. Canker or Dieback Disease: Fungal cankers can cause branches to brown and die back while other parts of the shrub continue to bloom. Look for discolored, sunken, or shriveled stems. Root Stress: After many years in the same spot, soil compaction, poor drainage, or root competition from nearby shrubs can weaken roses. Environmental Stress: Last winter’s cold snaps, summer drought, or inconsistent watering can also contribute. Recommendations Inspect the Canes: Cut into affected stems. If the wood inside is brown rather than green/white, prune those branches back to healthy tissue. Sterilize pruners between cuts (70% alcohol or 10% bleach solution). Monitor for Pests/Disease: Check for signs of fungal cankers, crown gall, or borers. Mulch & Soil Health: Refresh mulch to 2–3 inches (but keep away from the crown). Consider lightly amending with compost to improve soil structure and nutrients. Watering Practices: Provide consistent deep watering during dry spells, especially since stressed plants are more susceptible to disease. Rejuvenation Option: If more bushes continue declining, you may want to replace them gradually. Consider rotating in disease-resistant shrub roses or other flowering shrubs to diversify and reduce the chance of future loss. Since one plant has already died and others are showing decline, you may be at the natural replacement stage for part of the row. Healthy roses can last many years, but staggered replacement every few years can keep the planting full and vibrant.

Why is my swamp milkweed dying?
-
Date Posted: Thu, Aug 14 - 11:54 pm
- I have an established butterfly bush and swamp milkweed plant in my yard. They’re both around 3ft tall. This year, both plants began dying fast. We haven’t dumped anything there, nothing changed as far as plants, soil, drainage, etc. with one exception. Three years ago we planted some Blue Mistflower. It never came up until this year. It is climbing the dead butterfly bush. I’ve read Blue Mistflower spreads via rhizomes and that this could potentially be the cause. Any thoughts? Other things I should check? Thanks!
- Thanks for reaching out to the Richmond Master Gardeners! I've connected with one of our gardeners, Pam, that has a wealth of knowledge on native plants to help give you some guidance. There has been a lot of chatter in the Virginia Native Plant Society Facebook group that this has been a banner year for milkweed aphids. Swamp milkweed seems particularly susceptible to this aphid, and you truly have “a” plant (singular), it becomes the sole target for the aphids. The aphids submit a dew that causes a fungus. Unfortunately, the picture doesn’t show the milkweed clearly enough for this to be more than a guess, but we think it’s a reasonable possibility. We wouldn’t blame the blue mist flower. Yes, it’s hardy and loves to spread, but it’s a valuable late-season food source for pollinators. We recommend planting a different companion for it. You did not mention you soil or light conditions, but the Plant RVA Natives guide (download free at vnps.org) will help identify companion plants that can hold their own with an enthusiastic spreader. Pycnanthemum muticum, clustered mountain mint, might be a possibility, and it blooms much earlier, spreading the glory. Since butterfly bush is designated invasive in Virginia, we can’t ethically recommend trying to save it or replacing it with another. But its loss provides an opportunity to plant more natives. If you have additional questions about natives, Pam will be at the West End Branch of the Richmond Public Library on Wednesday afternoons after Labor Day. You are welcome to stop in and chat with her more!
