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!

Hydrangea Pruning
-
Date Posted: Wed, Jun 04 - 1:52 am
- Hello! My hydrangeas need some help. I inherited them with my new to me house in late fall, so this spring was my first opportunity to prune. They were already overgrown from the past owners. For the big leaf hydrangeas: I missed the fall pruning, so these haven't had a haircut since who knows when. The branches are getting weighed down from the weight of the flower and leaves, and the plant is very leggy. Should I try and start selectively and slowly clipping them back now or wait until they're done blooming and do it one big chop? If now, do I cut the old leggy wood back, or just the new green branches that are stemming from the old leggy wood (the two blooms on the top of the left bush are an example)? For the panicle hydrangea in the middle: I cut what I thought was way back this spring, but clearly not enough! Should I be trying to selectively trim some of this back now or bite the bullet and wait until spring and do a big chop? It's so tall and it's only May! Thank you!
- Thanks for reaching out—and congratulations on your new home and garden! It sounds like you’re giving your hydrangeas some thoughtful attention, which they’ll definitely appreciate. The blooms are beautiful! Here’s a breakdown of how to approach pruning both your bigleaf hydrangeas (Hydrangea macrophylla) and your panicle hydrangea (Hydrangea paniculata): Bigleaf Hydrangeas : These bloom on old wood, meaning the flower buds for this summer formed last year. That’s why heavy spring pruning can often result in fewer blooms. Since yours are blooming now, I'd recommend that you hold off on major pruning until after they finish flowering—typically by mid to late summer. Then you can: Remove about 1/3 of the oldest, leggiest stems at the base to encourage new growth from the bottom and lightly shape the plant by shortening stems that look untidy or weighed down. Avoid pruning after August, however, as that risks cutting off next year’s flower buds. In the meantime, if any branches are flopping badly or blocking paths, you can do a light, selective trim now—just avoid heavy cuts that remove flower buds. Panicle Hydrangeas: These bloom on new wood, so you have more flexibility with timing. You’re absolutely right that they can grow quickly in spring! For now, you can lightly thin or shorten a few of the tallest stems to maintain a more manageable shape but avoid cutting more than 1/3 of the plant this time of year. If it’s still too tall for your space, plan for a more significant structural pruning next late winter/early spring, before new growth starts. General Tips: Always cut just above a pair of healthy buds or a leaf node. Use clean, sharp pruners to avoid disease. Consider adding mulch and checking soil drainage if plants look stressed or leggy—bigleaf hydrangeas especially like evenly moist (but not soggy) soil.

Pruning a dwarf apricot tree
-
Date Posted: Thu, May 08 - 11:20 pm
- We have a dwarf apricot tree in our backyard near our privacy fence (designated by purple arrow in photo). Unfortunately, one of the medium size limbs at the top has stretched over our privacy fence into our neighbor’s yard. I want to but the limb but I’m nervous about damaging the tree since it’s spring time. Would it be okay to cut it at this time of year?
- Thanks for your question about pruning your dwarf apricot tree. It’s totally understandable to want to manage the limb growing into your neighbor’s yard, and you’re right to think carefully about timing. While late winter or early spring (before bud break) is generally the best time to prune apricot trees, light or selective pruning—even now in late spring—is okay, especially if it’s necessary to maintain boundaries or reduce potential damage. Just keep a few tips in mind to minimize stress on the tree: -Use clean, sharp tools to make a clean cut just outside the branch collar (the slightly swollen area where the limb connects to the trunk or larger branch). -Avoid removing more than 10–15% of the tree’s total canopy during the growing season. -Try to prune on a dry day to reduce the risk of fungal infections entering the fresh cut. If you only need to remove one medium-sized limb, your apricot tree should tolerate it well—especially if it's otherwise healthy. Make sure to monitor the tree through the season for any signs of stress (like leaf drop or dieback) and water consistently during dry spells.

Rhododendron Questions
-
Date Posted: Thu, May 08 - 11:14 pm
- I have an established rhododendron and a couple of questions 1. Some leaves tern yellow and die and fall off 2. Others show yellowing but remain 3. New shoots form at the base but die never to mature 4 is there any way to encourage new growth on the old branches
- Thanks for reaching out with your rhododendron questions! You’ve made some great observations, and your plant is definitely trying to tell you something. Here are a few possible explanations and tips based on what you described: Yellowing and Leaf Drop: Some yellowing and leaf drop is normal, especially for older inner leaves. However, widespread or early-season yellowing in Richmond can also point to stress from heat or underlying root issues, particularly since rhododendrons are naturally cool-climate, understory plants. Our warm springs and hot summers can make them more susceptible to systemic diseases or environmental stress. Persistent Yellow Leaves: This could be a sign of sun stress—rhododendrons prefer morning sun with dappled afternoon shade. Too much direct, hot afternoon sun can cause the kind of yellowing you're seeing. Poor drainage or soil that’s too alkaline can also cause nutrient uptake issues, leading to chlorosis (leaf yellowing). New Shoots Dying Back: When new shoots at the base fail to mature, it often points to root zone stress, such as poor drainage, fungal root diseases, or heat stress. Check that mulch isn't piled too high against the base and that the soil is staying moist but not soggy. Encouraging New Growth on Old Branches: Yes! Light pruning in early spring, just after flowering, can stimulate new growth. Avoid heavy pruning all at once; instead, gradually thin out leggy or unproductive branches over time. Make cuts just above a healthy bud or leaf whorl to encourage branching. Good luck with your rhododendron!

Growing Elderberries
-
Date Posted: Sat, Apr 12 - 12:43 pm
- Hello! I was just gifted a native elderberry and I'm looking for some advice. I also plan to get another one so they can bear fruit. I've been watching tons of videos but they all seem contradictory! I live in Richmond (Battery Park) with an urban yard - it's a bit bigger than typical row house size, and bordered by a shared fence on each side. I have a few areas to plant the elderberry where it will get at least 8 hours of full sun a day. My concern is that I want to keep the bush somewhat contained - I know they can grow quite large, but is there a way to prune it so it stays under 7-8 feet but still bears fruit? And, do you have any advice on how to stay on top of root suckers? I'm not sure how far the suckers will travel, but if they head into my neighbors yard I obviously wouldn't be able to see the sprout to know where to cut the root. I also heard the roots are quite hardy, so I'm trying to consider whether to plant near a retaining wall. In the videos I'm watching the plants all seem pretty naturally contained (versus something like blackberry which gets out of control), but I want to do everything I can to help out. Hoping I can make this work! I appreciate any advice you have. If helpful, I can send a photo of my backyard. Thank you, Julie
- What a lovely gift! I hope this will be something you are able to enjoy for years to come. And you are right! You will need a second one for cross pollination. We don't typically think of elderberries being wildly invasive, so I'd expect with your awareness of the need to keep an eye out for suckers, and your desire to prune it to keep it at a reasonable size, you will be pleased with your elderberry. A couple of pruning tips: Once the plant is established (after year 1 or 2), you can cut back about 1/3 of the oldest stems to the ground each year to encourage new growth. To keep overall height in check, you can also cut the remaining stems back to your desired height (just above strong buds). Many gardeners cut stems to about 3–4 feet in early spring, which results in a bush that finishes around 6–8 feet tall by summer. Managing suckers: You’re right—elderberries do sucker from the roots and can spread over time, though they are usually less aggressive than blackberries. The suckers typically emerge within a few feet of the main plant, though they can travel farther in ideal conditions. To manage them, check around the base of the plant regularly during the growing season and cut suckers at the soil line or dig back to the root and clip at the source. You might also consider planting your elderberries in a root barrier ring—digging a trench and installing landscape edging 12–18" deep around the planting area to contain the roots. Planting near a retaining wall: Elderberry roots aren’t known for damaging structures like a retaining wall, but they are persistent. If you're concerned about suckers creeping into a neighbor’s yard or through shared fences, planting 3–5 feet away from those boundaries is a good buffer. That space also makes it easier to walk around the plant and manage pruning or harvesting. Hope this helps as you decide where to plant! Best of luck to you! Hope you will enjoy your elderberries for years to come.

Finding Natives for a tough spot
-
Date Posted: Mon, Mar 17 - 4:33 pm
- Hello! We have a particularly difficult section of our garden in Richmond: it's a sloped spot between the driveway and the house, faces south, has pretty lousy soil, and is shaded by nearby oak tree. The only thing that we've been able to grow there is rosemary; everything else we've tried hasn't made it. Are there any native perennials that might survive?
- That sounds like a tricky spot, but there are some native perennials that could thrive in those conditions! Given that the area is south-facing but shaded, has poor soil, and is on a slope, you'll need plants that are drought-tolerant, shade-tolerant, and able to handle soil erosion. Here are some great Virginia native perennials that might work: Low-Maintenance Shrubs American Beautyberry (Callicarpa americana) – Handles some shade and poor soil, and has striking purple berries in fall. Witch Hazel (Hamamelis virginiana) – Tolerates shade and provides late fall yellow blooms. Perennials for Shade & Dry Conditions Columbine (Aquilegia canadensis) – A beautiful, drought-tolerant flower that does well in partial shade. Wild Geranium (Geranium maculatum) – A tough native with lovely pinkish-purple flowers in spring. Golden Ragwort (Packera aurea) – Great for erosion control and pollinators, with bright yellow flowers in spring. Ornamental Grasses (For Texture & Erosion Control) Little Bluestem (Schizachyrium scoparium) – Drought-tolerant and provides great fall color. (A favorite of mine!) Bottlebrush Grass (Elymus hystrix) – A native grass that thrives in dry shade. Since rosemary has survived, that suggests it’s well-drained soil, possibly a bit alkaline due to the concrete driveway. You may need to amend the soil with compost to help native plants establish, but once they do, they should require little maintenance.
