Figs, mint, strawberries and cilantro
-
Date Posted: Wed, May 06 - 2:08 am
- Hello, I purchased a small fig tree in a plant sale. However, I read after purchase that they can be really aggressive here in VA and choke other plants/roots extend so far that they can damage walls and foundation. I wanted to check if I should put it in a container or plant it as planned in an area that gets east and south Sun. If planted in the ground, how far should it be from structures? Is there an extra way to control its root growth ( pruning in the winter for example )? The same question for strawberries and herbs like sweat mint and cilantro. I read that they could spread and take over the garden and that a flower bed won’t keep them contained. Would they be better planted in a raised garden bed?
- It sounds like you had a great day at the plant sale and have several great questions! Starting with figs ... This is a really great resource about growing figs put out by the Virginia Cooperative Extension office and I believe it answers all of your questions: https://www.pubs.ext.vt.edu/content/pubs_ext_vt_edu/en/SPES/spes-760.html If you are interested in doing a soil test before planting, there are typically soil tests available from the local libraries. Also, if you'd like to see some examples of mature figs, including one that was recently pruned, you can visit Humphrey Calder Community garden at the corner of Thompson and Patterson. The pruning was done by the city to ease maintenance around the tree and protect the fence. Strawberries and mint are both eager growers and like to spread and can be challenging to control when planted in the ground. Personally, I always plant mint in a large grow bag. It is very happy there, comes back year after year, and is well contained. Strawberries can also be grown in containers easily, or you could make a small raised bed for them. There is another example of this at Humphrey calder - you will find a bed near the center opening area that is mostly strawberries, but the gardener grows other things in the middle of the strawberries, like tomatoes. The Piedmont Master Gardeners have a great resource about growing strawberries: https://www.piedmontmastergardeners.org/article/strawberry-basics-for-the-home-garden/ Cilantro is not something I have ever had to worry about taking over. It is very temperature sensitive and bolts easily as the weather warms. The cilantro I've been growing this spring has already bolted (gone to flower and forming seeds). I would recommend finding a shady spot for your cilantro, and if planting in a pot helps you get it in a shady spot, then that work perfectly fine. This is a great resource for growing cilantro in Virginia: https://gardenclub.org/blog/cilantro-cool-season-culinary-herb Good luck with your new plants! Have fun!

Odor from lawn
-
Date Posted: Thu, Apr 16 - 10:50 am
- Hi, we live in a townhouse in the fan that has a small backyard. This year and last we have noticed a pungent (almost skunky) scent that has started around mid-March and is gone in the winter. We think the cause is one of the plants/weeds that make up our “lawn” because the timing is just around when we start to see green again. The scent transfers to our dog when she lays in the grass. Any idea what type of plant would have this kind of smell? Or if there is anything we could do about it? I’ve attached an image of a portion of our yard but have others if that would be helpful. Many thanks!
- Thanks so much for reaching out and for sharing the photo, that’s really helpful. Based on your description of the timing and smell, one common cause we often consider is wild garlic or wild onion (Allium species), which can produce a strong, sulfur-like or “skunky” odor when crushed. However, I’m not seeing clear signs of those plants in the image you provided (they typically have distinct upright, hollow, grass-like leaves). What I do see is a mix of very common early spring lawn weeds, such as chickweed and bittercress, growing in a thin, somewhat compacted lawn. While these plants don’t usually have a strong smell individually, when they grow densely together and are disturbed by foot traffic, mowing, or a dog laying in the grass, especially when there’s some moisture present, they can release a musty, sulfur-like odor that can come across as “skunky” and can easily transfer to your dog’s coat. One other (less common) contributing factor could be compacted or poorly drained soil creating brief anaerobic conditions, which can also produce a sulfur-like smell; this is more typical in areas that stay damp, but it could be playing a small role depending on drainage. Over time, improving lawn density (particularly with fall overseeding) and reducing compaction can help crowd out these weeds and minimize the issue. In the short term, hand-pulling where feasible and giving your dog a quick rinse or wipe-down after being outside can help manage the odor.

VCU Garden Beds

Date Posted: Mon, Mar 30 - 2:36 pm
- I am trying to revive 8 garden beds in the courtyard of my campus dorm. The soil is currently dense w/ roots from the nearby mature trees, which have basically invaded the beds! I am unsure what we should do with the roots :( Do we cut them? Additionally, there is a little sapling that is groing magestically in the center of one of the beds.... I do not want to kill it, as it proves itself to be resilient. I am unsure what kind of tree it is, but I assume it grew form one of the seeds of the trees above. How can I excave and transport the sapling to someone/somewhere it can thrive? I do not have photos on this device, but I would love to share pictures in an email thread once you get back to me :) With much thanks in advance, Emma Toggia
- Thanks so much for reaching out to the Richmond Master Gardeners. What a wonderful project for your campus space! It sounds like you’re already putting a lot of care into bringing those beds back to life! What you’re seeing with the roots is very common when garden beds are located near mature trees. Those trees naturally extend their root systems into nearby soil to access water and nutrients. Regarding the roots, you can cut smaller invading roots (pencil-size or smaller) when preparing the beds but you should avoid cutting large structural roots, as this can stress or damage the tree. And unfortunately, even with cutting, roots will likely return over time, so it may help to add a layer of fresh compost and topsoil to improve growing conditions. When deciding what to plant here, we'd recommend choosing shade-tolerant, root-competitive plants like ferns and hellebores About the sapling: It’s great that you’d like to preserve it! You can attempt to transplant it, especially if it’s still relatively young. The best time to transplant is early spring or fall, but you can try now if you’re careful and keep it well-watered afterward. Dig a wide circle around the sapling to capture as much of the root system as possible (roots are often wider than you expect) Gently lift it, keeping as much soil around the roots as you can. There are some trees that have a very long tap root that can be nearly impossible to get out once they reach even a small size. If you find this to be the case with this tree, it may not be possible to save the tree and move it. However, if you are able to get the root ball out of the ground relatively intact, replant it promptly in a new location (or container), water deeply, and keep it consistently moist while it establishes. Do keep in mind that volunteer saplings often come from nearby trees and may grow quite large—so choosing an appropriate long-term location is important. If you have additional questions or want to share photos, you can reach us at rvamastergardeners@gmail.com. Best of luck with your garden beds, this sounds like such a meaningful project for your community!

Pruning Rosemary
-
Date Posted: Tue, Mar 03 - 11:11 am
- I moved into a house with an overgrown Rosemary bush. I love it but I think it needs some help. How would you prune it without killing it. I'm afraid if I trim it too far back it might die. I have no idea how old it is.
- Thank you for your question — what a gift to inherit a mature rosemary plant! Established rosemary can live for many years, but it does tend to become woody and overgrown over time. The most important thing to know is that rosemary does not reliably regrow from old, bare wood. If you cut back into thick, leafless stems, those sections often will not resprout. For that reason, pruning should be done conservatively and gradually. The best time to prune rosemary in Virginia is in early spring after the risk of hard frost has passed, or lightly after it finishes flowering. Begin by removing any clearly dead wood — you can gently scratch the bark with your fingernail to check for green tissue underneath, which indicates the stem is still alive. When shaping the plant, avoid cutting back into bare woody stems. Instead, always leave at least an inch or two of green growth on the stem. It’s safest to remove no more than about one-third of the plant at a time, especially if it is quite overgrown. If significant reduction is needed, spreading the pruning out over one or two growing seasons will reduce stress on the plant. When making cuts, trim just above a set of green leaves to encourage branching and fuller growth. If most of the plant consists of woody stems with growth only at the tips, you may be limited to light shaping rather than a dramatic cutback. In that case, you might consider taking a few soft cuttings in spring to start a new plant as a backup. Good luck! I love having fresh rosemary to pick from in the backyard! I hope you will be able to enjoy this plant for many years to come.

Planting under a Magnolia
-
Date Posted: Wed, Jan 14 - 1:33 am
- I have a magnolia tree in the front yard and underneath it it's mostly dirt. I don't really want to plant grass there but I wondered if you might suggest something that I could plant under the tree so it's not so muddy. My grandchildren get very muddy after a rain. I took a picture so you can kind of see what it looks like. It has a little bit of morning Sun but mostly shady during the day. Thanks for your help. I
- Thanks for reaching out to the Richmond Master Gardeners with this question! This is a very common situation under magnolias, so you’re not alone—and you’re smart to avoid trying to force grass there. Magnolia trees have shallow, wide-spreading roots and create dense shade, which makes it hard for turfgrass to survive. We are always gravitating towards native options anyways. A favorite of mine for a situation like this is a sedge. Pennsylvania sedge (Carex pensylvanica) is one of the BEST grass-like alternatives for shade. It looks neat, stays low, and is much tougher than turfgrass. (https://vaplantatlas.org/index.php?do=plant&plant=1242&search=Search) Some other native ground cover options you could consider are: Green-and-gold (Chrysogonum virginianum) Semi-evergreen, spreads slowly, cheerful yellow flowers in spring https://vaplantatlas.org/index.php?do=plant&plant=1776&search=Search Wild ginger (Asarum canadense) Excellent for shade, soft leaves, great soil cover https://vaplantatlas.org/index.php?do=plant&plant=2009&search=Search https://vnps.org/wildflowers-of-the-year-2/2010-wild-ginger-asarum-canadense/ Creeping phlox (Phlox stolonifera) Handles partial shade, beautiful spring blooms https://vaplantatlas.org/index.php?do=plant&plant=3156 A couple important things to keep in mind before planting anything under a magnolia: Avoid digging deeply (to protect roots) and do not pile soil or mulch against the trunk. You could consider covering some of the space with mulch - just be sure not to pile it against the trunk! Good luck!!

Hydrangea identification & tips
-
Date Posted: Fri, Oct 31 - 10:02 am
- Any idea what kind of hydrangea this might be? It was in the garden when we moved in. Maybe the first year a couple of pinkish blooms but last year nothing In particular any suggestions for pruning would be appreciated
- Thanks for reaching out to the Richmond Master Gardeners and for including the picture! From your description and photo, we think your hydrangea is most likely a Hydrangea macrophylla (French hydrangea). French hydrangeas are deciduous shrubs known for their rounded clusters of pink, blue, or purple flowers. And it sounds like your plant is still young, which can explain the limited blooming so far — these shrubs often take a few seasons to establish before flowering reliably. Here are a few tips about pruning to help improve your blooms: Hydrangea macrophylla blooms on old wood, meaning next year’s flowers form on stems that grew this year. Because of that, pruning at the wrong time can remove potential flower buds. Only prune right after the plant finishes blooming (early to mid-summer). Avoid pruning in fall, winter, or spring, as this will remove next season’s buds. When pruning, remove only dead, damaged, or very weak stems, and lightly shape the plant to improve airflow. Older, woody stems can be cut back at the base every few years to encourage new growth. A few other things to note about these hydrangeas: They prefer partial sun — ideally morning sunlight with afternoon shade. They like moist but well-drained soil rich in organic matter. You can add compost to improve texture and moisture retention. They should be kept evenly moist during dry periods, especially in hot weather. If your soil is naturally acidic, you may also notice the flower color shift toward blue; in more alkaline soil, blooms stay pink. We hope these tips will help you see more blooms in the years to come!

Fall Native Seed Sowing
-
Date Posted: Tue, Oct 21 - 12:33 am
- I am getting ready to sow native flower seeds. I plan on just casting them on soil (blanket flower, tickseed sunflower, cardinal flower, salvia, turtlehead and coneflower) I have some heavily mulched areas and understand I should rake that back so they contact the dirt and rake it back in the spring. I also have a lot of trees and wonder if it's ok if seeds are covered w leaves, or should I wait until all of the leaves fall and clear the area as I would the mulch? Thank you!
- Thanks for reaching out to the Richmond Master Gardeners! Those are all wonderful native choices that benefit from being sown now so they can go through a natural winter cold stratification period. You’re also correct that good seed-to-soil contact is key for germination. Here’s how to approach each situation: Mulched areas: Yes — rake the mulch back before sowing so the seeds can fall directly onto the soil. After seeding, gently press them in (you can even walk over the area) so they make contact with the soil surface. Leave the mulch off for winter and rake it lightly back in the spring after seedlings start to emerge and you can see where they’ve sprouted. Leaf-covered areas: A thin layer of leaves is fine — it can even help protect seeds from washing away and mimic natural forest duff. However, a heavy mat of leaves (especially large, flat ones like oak or maple) can smother seeds and block light in spring. If you have thick leaf cover, wait until most have fallen, then lightly clear the area before sowing or thin the layer to about an inch so seeds can still reach the soil and get some light and moisture. Good luck! We hope you have lots of success!

Transplanting a peach tree
-
Date Posted: Thu, Aug 14 - 5:34 pm
- I need to transplant this peach tree but know next to nothing about when/how/where. Would love advice!
- Thank you for reaching out! Peach trees can grow successfully in the Richmond area when given the right conditions and care. Since your tree is currently in a pot, here are some steps and tips to guide you through transplanting it into the ground: Best Time to Transplant Late fall to early spring (after leaf drop but before buds swell) is ideal. In Richmond, that’s typically November through March when the tree is dormant. This reduces stress and gives roots time to establish before summer heat. Choosing a Planting Site: Sunlight: Choose a location with full sun — at least 6–8 hours daily. Soil: Well-drained, loamy soil with a pH of 6.0–6.5 is best. Avoid low areas where water collects. Soil test kits can be found at local Richmond Public Libraries Air Circulation: Good airflow helps reduce fungal diseases. How to Transplant: Dig a hole twice as wide as the root ball and just as deep. Loosen the surrounding soil to encourage root spread. Gently slide the tree out of the pot, loosening any tightly wound roots. Trim circling roots to prevent girdling. Place the tree so the root flare (where roots meet trunk) is level with or slightly above ground level. Fill with native soil (you can mix in some compost if soil quality is poor). Water deeply to remove air pockets. Apply 2–4 inches of mulch around the base, keeping it a few inches away from the trunk. This helps conserve moisture and regulate temperature. After planting: Water deeply once a week during the first growing season, more often in hot/dry spells. Lightly prune in late winter to shape and remove damaged branches. Young peach trees can be susceptible to deer, rabbits, and voles, so consider fencing or trunk guards. Good luck with your peach tree!! We wish you lots of success! Thanks again for reaching out.

Pruning limelight hydrangeas
-
Date Posted: Tue, Jul 15 - 10:37 pm
- I read that hydrangea blossoms need to be cut by the end of July or the plant won’t blossom next year. I have a limelight hydrangea. Is that true?
- Thanks for reaching out! That advice applies only to hydrangeas that bloom on old wood, like bigleaf (macrophylla) or oakleaf (quercifolia) varieties. These set their flower buds in late summer or early fall, so pruning late removes next year’s blossoms. But Limelight hydrangea (Hydrangea paniculata ‘Limelight’) is a panicle hydrangea, which blooms on new wood—the current year’s growth For limelight hydrangeas, we recommend pruning in late winter or early spring, before new buds emerge. You can prune again in fall or winter to remove dead wood and shape the plant. It is not necessary that you prune your limelight by the end of July - you can continue to enjoy blossoms through the summer!

Pruning Oakleaf Hydrangeas
-
Date Posted: Fri, Jul 11 - 12:54 am
- I have an oakleaf hydrangea that has grown too large for its spot in my yard here in Richmond. When is the best time to cut it back and should I cut its branches close to the trunk? Can it be encouraged to grow more vertically and not spread out horizontally?
- Thank you for your question about your oakleaf hydrangea (Hydrangea quercifolia)! I frequently walk past the ones Maymont has in their parking lot at the nature center and am always admiring how beautiful they are but they can indeed outgrow their space over time. Timing: The best time to prune oakleaf hydrangeas is shortly after they finish blooming, typically in late June through early August here in Richmond. These shrubs bloom on old wood, meaning they form next year’s flower buds on stems grown the previous year. Pruning in late summer or fall will likely remove those buds and reduce flowering the following year. How to prune: Avoid cutting branches all the way back to the trunk. Instead, remove about 1/3 of the oldest, thickest stems at the base to encourage new growth and improve shape. You can also shorten some of the remaining stems to reduce overall size and guide the shape—just make cuts back to a bud or side branch. Encouraging vertical growth: Oakleaf hydrangeas naturally have a broad, spreading habit. While you can’t dramatically change this growth pattern, you can encourage a more upright form by thinning out wide-angled branches and encouraging vertical shoots, selectively removing outward-growing stems to reduce width, and/or using light staking or support for young vertical stems if needed (though this is more effective in younger plants). If the space is truly too small for the mature size of your shrub, long-term, you might consider relocating it in the fall or early spring when it’s dormant. Good luck and happy gardening!
