Serviceberry TLC

    Date Posted: Thu, Jul 31 - 10:56 pm

    Question

  • My service berry tree has split bark in several places and there may be insects in the bark. There are many yellow leaves. The tree doesn’t look healthy. I planted it in the fall. Is there anything I can do to save it?
  • Answer

  • Thank you for reaching out! It sounds like your serviceberry tree is experiencing some stress, but we’ll do our best to help you support its recovery. Yellowing leaves can indicate a few things: transplant shock, water stress, or even nutrient deficiency. This is common in newly planted trees as they adjust to their environment. Split bark can also be a sign of environmental stress like rapid temperature changes in winter (known as frost cracks or sunscald), mechanical injury (e.g., weed trimmers or animals), and overwatering or underwatering. Unfortunately, splits in the bark can make the tree more susceptible to insect or disease invasion. If you see insects, they may be opportunists rather than the primary cause. What You Can Do: Inspect the trunk: Look closely at any insects you find. If you can, take a clear photo to try to ID. Mulch properly: Place a 2–3 inch layer of mulch around the base of the tree (keeping it a few inches away from the trunk) to regulate soil temperature and moisture. Water consistently: Deeply water once a week during dry periods. Avoid overwatering—serviceberries prefer moist but well-drained soil. Prune carefully: Remove any obviously dead or damaged branches, but avoid heavy pruning during stress periods. Avoid fertilizer for now: Wait until the tree is more stable before fertilizing. It may take some time for your serviceberry to bounce back, but with proper care and monitoring, it could still recover. We wish you the best!

Extension Turf Grass program

    Date Posted: Fri, Jul 18 - 1:26 am

    Question

  • Status of turf program. Sent in $45.00 In may/ june with no confirmation so far.
  • Answer

  • Hello! The Richmond Master Gardeners are not connected with a turf program. And I'm not personally familiar with the city of Richmond offering one, especially since the city has been without an extension agent for the last several years. I would be curious to know what address you sent it to. I was able to find that Henrico does offer a program, but that it is unfortunately suspended this year: https://henrico.ext.vt.edu/programs/anr/smartlawns.html I can try to help you find a resolution. Please email RVAmastergardeners@gmail.com with the address you used and any other information you have available and I will see if I can help you get some answers. Thank you!

Preparing new garden beds for planting

    Date Posted: Tue, Jul 15 - 10:50 pm

    Question

  • I need to landscape front garden beds. what’s best to place on top of area for two months. Are tarps weighed down w/bricks okay? Arborist chips clean? I’m old so I want something easy/low maintenance. Planning on native perennials and grasses, a few shrubs/service berry.
  • Answer

  • Thank you for your question! It sounds like you're off to a great start with a thoughtful plan for a low-maintenance, native landscape. Both of the options you suggested are great ideas for prepping your beds for planting. 1. Tarps: Yes, tarps weighed down with bricks or secured with lawn staples can work well to smother weeds and prevent new growth before planting. This method is known as "occultation." It’s easy, effective, and doesn't require much labor. Just make sure the tarp is opaque and tightly secured to prevent wind from getting underneath. I have personally had success with using black plastic and lawn staples, and am able to re-use the black plastic when I'm ready to expand the garden. 2. Arborist Wood Chips: Fresh arborist chips are also a great option, especially for a native planting. They help suppress weeds, retain moisture, and gradually improve soil as they break down. It’s fine to apply them now even if they’re “green” (fresh)—just keep them 3–6 inches deep and avoid piling them right against any existing stems or trunks. You can combine both methods too: tarp the area now, then remove the tarp and add arborist chips once you’re ready to plant. Native perennials, grasses, and a few shrubs like serviceberry are perfect choices for a low-maintenance, pollinator-friendly garden. Once established, they should need minimal watering and upkeep. Happy gardening!

Pruning Oakleaf Hydrangeas

    Date Posted: Fri, Jul 11 - 12:54 am

    Question

  • 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?
  • Answer

  • 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!

Bitterness in Cucumbers

    Date Posted: Tue, Jul 01 - 1:28 am

    Question

  • I'm growing cucumbers for the first time this year, and so far have only harvested a few. They are heirloom straight 8 cucumbers I started from seed. I'm harvesting them at about 6 inches long. I cut the ends off when I slice them to avoid bitterness, but they still seem to taste quite bitter and soapy. I'm not spraying them with anything, and I was them well with water when I harvest them. What might be making them bitter?
  • Answer

  • Thanks for reaching out to the Richmond Master Gardeners! Bitterness in cucumbers—especially heirloom varieties like Straight 8—is a fairly common issue, although frustrating, and it’s usually due to the natural compounds called cucurbitacins. A few reasons you might be experiencing bitterness: First off, we have to think about environmental stress, especially given the extreme heat and big down pours we have been having. Cucurbitacin levels tend to rise when the plants are under stress and common stressors for cucumbers include: Inconsistent watering (periods of drought followed by heavy watering), high temperatures, and also poor soil fertility or nutrient imbalance. Straight 8 cucumbers tend to be prone to bitterness, especially in hot and dry conditions. Try to keep soil moisture even by watering regularly (especially during hot spells), and consider using mulch to conserve moisture and keep soil temps steady. There's a chance your cucumbers are sitting on the vine a little too long and getting a little overripe. If you notice any yellowing of the skin or a hard waxy exterior, they are likely getting a little too ripe. You could try harvesting a little sooner, maybe when they are 5 inches, to see if that helps. As you already seem to know, the bitter components are most concentrated at the the stem end, in the skin and just under the skin. In addition to trimming the end of off, you could try peeling the cucumbers. I've also heard of people soaking them in cold salted water for about 40 minutes once they are peeled. I haven't tried this myself, but I've heard it helps to reduce the bitterness. Their are some hybrid varieties that are bred to reduce bitterness. If none of the above ideas help you to reduce bitterness, you could try growing a hybrid variety next time and see if that helps. Good luck! We hope you are able to enjoy your cucumbers!

Plant ID: Common Blue Violet (Viola sororia)

    Date Posted: Mon, Jun 09 - 7:29 pm

    Question

  • Is this plant A weed Invasive
  • Answer

  • Thank you for reaching out to the Richmond Master Gardeners! Based on the photo you shared, the plant appears to be Common Blue Violet (Viola sororia). While some gardeners consider it a weed due to its ability to spread vigorously, it is actually native to the eastern United States, including Virginia. Its spreading habit can be a challenge if you're aiming for a more controlled or manicured landscape. However, it also offers ecological benefits: it's a host plant for fritillary butterfly larvae, supports pollinators, and provides low-growing ground cover, especially in shady or naturalized areas.
