Natives!!

    Date Posted: Thu, Jul 21 - 7:35 pm

    Question

  • 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!
  • Answer

  • 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.

Native Plants

    Date Posted: Mon, Apr 25 - 4:23 pm

    Question

  • I’m interested in filling a mulched area in my yard in the city with native plants. Do you have any recommendations for layout and where to buy? I was hoping for a rain garden but it’s not enough space. It’s about 10 feet by 3 feet.
  • Answer

  • Hello there! What a timely question. Master Gardeners are exploring this very subject on May 7th at the park at the Main Library between 1-4. There will be a presentation on invasive plants by the JRPS Invasive Plant Task Force followed by Master Gardeners presenting on native plants with plenty of time for questions and answers. Without knowing the orientation, amount of sun, and soil conditions, etc., it's difficult to make a suggestion for your planting. However, I would recommend making as many layers as possible-shade, understory, shrubs, perennials and groundcovers. I know it's not a large area but you would be surprised how many plants can inhabit a space that size. You could omit the shade tree perhaps and plant an understory or two-one at each end of the space. Then infill with a mix of shrubs and perennials and finally underplant with a groundcover or two. This diverse mix will be very attractive to many species of birds, mammals, insects, etc. Please come with your questions and curiosity on May 7th!!

Compost

    Date Posted: Fri, Mar 18 - 8:48 pm

    Question

  • Hello, I tried container gardening last year for the first time and really loved it. I’m looking to try again this year. I’ve collected a lot of free pots over the year, and have a good amount of space outside for them, but I am low income and can’t afford to buy more than a few bags of potting soil. Do you know of any cheap or free soil or compost give away programs in richmond? I can’t compost myself here because I live in a apartment that is susceptible to roaches.
  • Answer

  • Hello there, So glad to hear you're planting in containers. It's amazing how well that can work. While there is no public resource for free or cheap compost (hopefully someday....) I reached out to the other Master Gardeners and a couple of them are happy to share some of their own. If you email me at jrreilly2323@gmail.com, I can send you the contact information for the individuals that have compost to share. Please let me know if you have any further questions.

Low-maintenance ground cover

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

    Question

  • 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!
  • Answer

  • 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!

Transplanting Hydrangeas

    Date Posted: Fri, Nov 05 - 1:58 pm

    Question

  • I have hydrangeas in a partial sun location, mostly afternoon, and they have never done very well with adequate watering and fertilization If I’m going to move them to a new location, what scenario should they be in and are there any specific times that are better to move them?
  • Answer

  • Greetings! Thank you for your question. Now is a great time to transplant your hydrangeas (Fall season), while the plants are dormant. Plant your hydrangeas in an area that gets morning sun, and afternoon shade. Hydrangeas do not like the hot afternoon sun we have here in Richmond in the summer months, and that may be why they have not done well in their current location. When you transplant, be sure and select a location that will drain well, and amend your soil with plenty of compost. Be sure and dig the hole large enough to accommodate the entire root ball. Water the hydrangea well once you place it in the new location. As you know, hydrangeas love to be watered in the warmer months, and they love nutrient-rich, composted soil. If they are planted near larger plants or trees, they may be competing for water during the warm months, and it will be important to keep them moist (but well drained). Good luck with your fall gardening!

Overwintering Geraniums

    Date Posted: Thu, Nov 04 - 8:07 pm

    Question

  • I have a geranium that was brought indoors a few days ago and still has blooms. How to I store it in the winter months? I heard you can cover it with a plastic bag and keep it in a dark, cool place - ie. garage. Is that Ok? Does it need to be watered? Thanks, Lori Pettit
  • Answer

  • Hello Lori, You have a couple of options for your geranium. The first would be simply keep it indoors as a house plant assuming you have enough window space/light. Another option would be to unpot the plant, shake off as much soil as possible, and store the plant in a paper bag in a darkened cool space. Ideally, the temperature would range in the 45-55 degree area. A garage could work if you manage to keep the temperature at that range. I prefer the first method because you get to enjoy the plant all winter. There's also less chance you'll forget about it next spring!! It will most likely go through a transition phase and you may lose a few leaves but with enough sun it should continue to bloom (probably somewhat less) all winter and into early spring. If the geranium is very large and will possibly take up too much space inside, feel free to cut it back to about 8 inches. It will spend the winter putting on some more growth. As the temperature warms in spring you can start introducing it back to the great outdoors. Somewhere around mid-April (after the last frost) move it to a shady spot for a few days so it can acclimate and then move it to your preferred place. Good luck with this process!

Ambrosia beetles-Dogwoods

    Date Posted: Tue, Oct 05 - 4:24 pm

    Question

  • Ambrosia beetles-dogwoods
  • Answer

  • Hello again, I have a few questions about your trees. I'm wondering how they were diagnosed. Did you see the frass tubes (kind of looks like tooth picks) on the trunk? Was there blue staining in the sapwood when they were removed? You may also have seen 'sawdust' at the base from the process of tunneling in the entry holes. Those would be definite indicators of the beetle. Generally, they attack trees under stress, such as drought or lack of appropriate amounts of scheduled watering. The pests may have been in the trees when you purchased them from the nursery. If so, the guarantee from the nursery may cover your loss. Assuming the reason your trees failed was due to ambrosia beetle and not another pest or disease, the arborist I consulted said that planting in the same location would be fine. I don't believe they have created any trees to be resistant to the ambrosia beetle. That being said, I think the chief thing is to provide the best cultural environment for the trees to survive. Well-draining soil is key along with proper placement and watering until the trees are established. Without knowing the exact environment you are planting in it would be difficult to recommend a particular tree. Look online for a list of native trees for this area and then consider the location you have and whether or not that tree would be a good fit. Consider the amount of light, moisture, available space for mature height, etc. Sorry those dogwoods didn't make it. Best of luck with your next choice.

Ambrosia beetle-Dogwoods

    Date Posted: Sun, Oct 03 - 5:27 pm

    Question

  • Last year I put in 4 dogwoods trees but ambrosia beetles appeared in April/May and the trees all died. Is there any type of native tree that is resistant to them? The trees were removed in June but are the beetles still in the soil? I'm afraid to put in any new trees now.
  • Answer

  • Hello there, thank you for your question. It will take a little longer to answer because I'm reaching out to an arborist for assistance. Thanks for your patience!

Black-eyed Susan

    Date Posted: Sat, Oct 02 - 4:51 pm

    Question

  • Some of the leaves on my Black Eyed Susans have turned brown. Could this be a fungal infection? And if so, how can I treat it? Also, could you recommend a Black Eyed Susan that is disease resistant?
  • Answer

  • Hello there, Without knowing the variety, I'm going to guess that it's Goldsturm, (it may not be but that is the most popular variety). These plants can succumb to fungal and bacterial issues. I can't specifically say what is ailing your plant but you can implement a few cultural changes to see if that helps. Your plants should have good drainage AND good air circulation. Soil and air would be the first factors to check. If you think you have that covered and the plant is not recovering it would be wise to remove the plant and discard it in the trash. If you have other plants that are in good health still you may want to treat them preemptively with a baking soda or neem spray. Additionally, if you want to plant again in that same spot where the ailing plant was you will need to use fresh soil in order to avoid a repeat of the situation. I came across a helpful list of species and cultivars of rudbeckia on a website of an organization based in Baltimore called Blue Water Baltimore. There are many other rudbeckias that may be more suitable for your particular situation. Here is the link--https://bluewaterbaltimore.org/blog/how-to-choose-a-black-eyed-susan/ There are many lovely varieties to choose from and those that can handle humidity would probably be a great choice. Good luck!

invasives

    Date Posted: Fri, Aug 27 - 3:36 pm

    Question

  • 1) I have rampant overgrowth of wisteria, as well as more limited poison oak in an area covered by pine straw, ornamentals on perimeter of area, but worst parts are distant from these bushes. 2) Also widespread seeding from a mimosa (since cut down, but too late) throughout the front lawn. I'm averse to using Round-Up, and wonder if you can offer solutions and guidance. Many thanks! Catherine Davis
  • Answer

  • Hello there, There's a lot do here. The wisteria should probably be dug up and put in the trash. They are rampant vines. I have seen some people do an excellent job of training them and keeping them in bounds. It all depends on your maintenance tolerance. If they are left to run wild they will climb trees and kill them over time. The poison oak (which I think is actually native but no one actually wants it in their yard) should probably be smothered. I understand you not wanting to using Round-up or a similar product, I wouldn't use it either. If they are young and small plants depriving them of sunlight, water and nutrients will over time kill them off. It could take several months but doing it now with this hot weather will help the soil heat up to kill the plants. Tarps, cardboard, plastic sheeting, these should all work. This process works best in sunny sites, you didn't mention the exposure. I've also had success using straight white vinegar on any plants that survive and re-sprout. And of course, be sure to wear protective clothing, head to foot, any time you are working with poison oak or ivy and put the clothes in your waster with hot water when you're done. As far as the mimosa seedlings, I can only imagine hand pulling them. I don't know the area in question but using vinegar in your lawn will damage the grass and I'm sure you don't want that. Hand pulling is one of the most effective methods to use when possible because you can often get the root of the plant out. Having a good thick ground cover is the best bet for keeping out all those unwanted plants. If there's a vacancy, they'll occupy it!! Best of luck Catherine!!
