Date Posted: Sun, Feb 11 - 11:50 pm
- Just called ahead about soil test kits and the librarian says they’re out and the other branches are out of them as well. When might be in stock again?
- Thank you so much for letting us know that the library branches are all out of soil test kits. We definitely want to be sure they are restocked ahead of spring planting season! We will be working with the extension office and hope to have the branches restocked by the end of this week.

Stunted vegetable garden
-
Date Posted: Sat, Aug 12 - 6:55 pm
- My vegetable garden has been stunted in its growth this summer and I’ve been trying to figure out what I can do differently. I think we may have some Red Thread in the yard.
- I think many local vegetable gardens have experienced some stunting this year. The prolonged cooler weather we had at the beginning of the summer seemed to have a big impact on plants that were put in the ground in late April and May. In addition, we have had several periods with very little rain to help keep gardens watered which has also been having an impact. Before planting next year, its a good idea to do a soil test to see where your soil could use some support. Soil tests are available through the master gardeners at your local library. You can use these results to ensure you are planting in a robust healthy soil that is ready to provide a good home to your plants. Also, if you aren't already doing this, I would suggest fertilizing your garden with an organic fertilizer. Organic fertilizers slowly release nutrients giving a steady supply of food to your plants without disrupting the work of earthworms and other beneficial organisms. Follow the recommendations on the label for frequency of fertilizing. I'm not aware of nor have I been able to find any literature on red thread having an impact on anything other than turf grass. I'm not sure if you mentioned that in correlation with your concerns about your vegetable garden or as a separate concern. However, if you were looking for recommendations to deal with the red thread as well, fungicides are not usually advised for red thread control on residential turf for various reasons. The disease is largely cosmetic. Unless environmental conditions that promote disease development persist for extended periods, the turf will recover — usually with no lasting effects of infection. Good luck and happy gardening!

Natives & Landscaping
-
Date Posted: Mon, May 29 - 5:34 pm
- I have a wonderfully overgrown, half-wild backyard in the Northside that already attracts a great variety of birds ... but I'd like to start being more purposeful about planting natives and landscaping for birds and bugs. I'm having a hard time figuring out where to start, though, and am hoping a Master Gardener could help. Is there someone who could come look at my site and help me come up with a plan?
- Hello! How lovely to have a backyard that is already attracting a great variety of birds! It's wonderful that you want to provide more native plants for your backyard pollinators! A good place to start is by doing a soil test to see how healthy your soil currently is and if there is anything you should add to it before you begin planting. You can find soil test kits at your local libraries when the master gardeners are there, just call and ask your librarian. Next, you will want to think about how wet or dry your back yard typically is, as well as how much sun light you get. You could bring this information along with some pictures to talk with the master gardener at your library or to a local nursery for more guidance. I would also recommend looking over this really wonderful resource on native plants for our area https://www.plantvirginianatives.org/plant-rva-natives as the free downloadable guide has an amazing amount of information to help get you going in the right direction! Happy gardening!
Question

Allium Leaf Miner
-
Date Posted: Sun, May 28 - 8:55 pm
- I think I might have allium leaf miner in a few of my overwintered leeks. I took pictures, video and saved a sample in a ziplock bag containing the reddish brown egg. I’m not particularly worried about the crop but wasn’t sure if I should contact you since it’s a relatively new invasive pest. It seemed like covering and exclusion measures will be my best bet going forward. Thanks!
- I'm sorry to hear your leeks have been hit by the allium leaf miner. There are a few prevention techniques to consider going forward. 1. Solarization. The garden bed can be covered with clear plastic for four weeks over the summer, being sure to bury the edges so heat is trapped. Solarization will kill allium leaf miner pupae, decrease soil pathogens, and increase beneficial microbes. 2. Rotation Planting. Refrain from planting members of the allium family in the same bed for one year or longer since the pupae will overwinter in the bed. 3. Cover crops. Consider planting members of the cabbage family in the bed prior to planting allium. The sulfur produced by the cabbage crops will transfer to your allium making them more pungent and less desirable to the fly. Another benefit is that brassica plants decrease the amount of nitrogen available in the soil which is beneficial as flies are more drawn to high levels of nitrogen in plants. 4. As you have already mentioned, row covers. Cover the plants at planting time in the fall (September/October) and remove for the winter. Plants will need to be covered again for the spring (March/April) before overwintering pupae emerge. Since the allium leaf miner is very small, it's important to be sure the edges of your covers are pinned down well or buried. Thank you for reporting this finding so the spread of allium leaf miner can be monitored and best of luck with your future plants!

Rhododendrons
-
Date Posted: Wed, Apr 26 - 3:24 pm
- I have several rhododendron bushes in my front yard. They usually bloom once a year. I would like them to bloom more often. I don’t understand why one of the bushes leaves turned completely brown and died. Will this bush come back? Should I pull it up? What can I do?
- Hello there, Rhododendrons bloom once a year, in late winter into spring depending on variety. You could add other varieties with different bloom times to extend the show. You could also add some azaleas (which are in the same family). Some of those do bloom twice a year. The variety Encore comes to mind. As for the browning of the leaves and leaf drop, a number of issues could be causing that. Poor drainage, leaf burn from too much sun, winter burn, nutrient deficiency. It's difficult to diagnose in this manner. But you can try this practice - if you give the plant plenty of time to begin spring growth—waiting until late spring—you can then scratch the bark on dead-looking branches with your fingernail. If there is green wood underneath, the branch is still alive. Leave it be and it may very well leaf out. If it's brown underneath, the branch is dead and you can prune it off. Also, you can visit one of the Master Gardeners that man the desk at your local library. Call the library to see when the Help Desk is in session. Any information you have about the plants-photos, samples, will be helpful. But sometimes you need to assess the planting environment to narrow down the problem. You can also get a soil testing kit and the results will help you improve the nutrients and condition of your soil to ensure future plant health.

Ilex glabra-Inkberry
-
Date Posted: Thu, Apr 20 - 8:37 pm
- We planted 5 ilex glabra bushes in October. One of them suddenly (within less than 12 hours) had it's leaves turn brown/black and fall off. The stalks and stems all seem fine, and it still has some leaves on one side. The other ones all seem fine, although they haven't grown much and have a few yellow/brown leaves. Do you know what happened and what we can do to protect the plants? Thank you!
- Hello there, Sorry to hear of your situation. Unfortunately, it's difficult to diagnosis from this distance. It could be soil, possibly chlorosis, maybe spider mites. First, I would contact the garden center where you purchased your plants. Often, plants are guaranteed for a year. So if you have proof of purchase I would definitely tell them about the condition of your shrubs, what they advise and what they can do for you. You could also check in with one of the Master Gardeners that man the help desks at the library branches. Check out your local library and find out what days and times the help desk is manned. It may still be difficult to diagnose without seeing the actual planting. Bring pictures and as much information about where the shrubs are situated. You can also get a kit for a soil test from the Master Gardeners, which may be helpful to ensure the future health of the 10 plants. There is also a plant clinic but again, I would start with the garden center where you made your purchase. And, of course, check in with a Master Gardener. They are a wonderful resource.

Starting a new garden
-
Date Posted: Sat, Mar 25 - 4:25 pm
- Hi! I live off of N 18th St. and my apartment building has a very large bed that has been empty for a while and that I would like to start growing in (herbs and vegetables). I plan to come pick up a soil kit to test the current soil in the bed. Is that a first step you'd recommend? After testing the soil, are there specific veggies and herbs you'd recommend for the climate/area we're in? Are there any recommended local places that I could get starters and/or transplants? I also have read that I'll likely need to turn the soil to loosen it up. Welcome suggestions. Thanks! - Marg
- Hello Marg, Nice to hear you're interested in growing food. My first question/concern is if you have cleared this project with the owners or property manager of the apartment you're living in. That would be the first item on the check list. After that, testing the soil is a necessary step. Then, depending on the results, you would add any needed amendments. You can never go wrong by adding compost to the bed. Compost is a good addition because it can lighten heavy soils and enrich sandy soils. As far as what to plant, that would really depend on what you want to plant. I would make a list of desired vegetables and herbs and then see what zone they are appropriate for. Your basic tomatoes, zucchini, basil and parsley will do fine here. The important thing is to check the zone and maturity dates for whatever you are planting. If you want to plant spinach or lettuce or similar greens be aware that they like cool temperatures so they'll need a head start. When it gets too hot they will "bolt" or go to seed and be done for the summer planting season. You can pull them and replace them with a heat-loving vegetable. They can also be planted again as a fall crop when the weather starts to cool a bit. You can find seedlings at most garden centers. I think that Lowe's, Home Depot and similar stores offer some organic seedlings. I would check about both types of stores to see if they offer what you want to plant. Please check out the Master Gardeners who man the help desks at your local library. Check in with the library to see what days and times the gardeners are available. They will give you a wealth of information and advice. Also, if you go to the Main Library there is a seed bank (in an old card catalog) near the indoor entrance. The availability of seeds waxes and wanes but it's worth a try! Good luck with your project. Happy gardening!
Question

Chamomile lawn
-
Date Posted: Sun, Mar 05 - 1:28 am
- Hi there! We live in the Museum District, and have a very small front lawn area, currently covered in mulch, in direct sunlight. We are interested in planting a chamomile lawn there. Do you know anyone who's done this in the area? Do you know where we could source chamomile plants, as opposed to having to sprout the seeds ourselves? Any suggestions in particular? We know that once we plant it, we can't walk on it for a few months. Many thanks!
- Hello there, this is a nice idea. I'm thinking you're thinking of Roman chamomile, the perennial (the low growing version which is short lived but will self seed, which is a plus). Unfortunately, I don't have a source for chamomile plugs. However, if you have a nursery you like you could try calling them to see if they might be able to order some plugs for you so your lawn gets off to a quicker start. You may also be able to save some money by buying plugs. I know you have a small space to work with but I'm wondering if you wouldn't want to add another layer to the planting, to maximize the pollinator opportunities. It might be nice to have the ground covered with chamomile and some other plantings of echinacea or rudbeckia in a grouping or two. Either way, I think you'll be happy with the change. Good luck and happy gardening!
Question
Answer
Native shrubs
-
Date Posted: Mon, Jan 09 - 5:37 pm
- Hello, I am looking for a shrub to plant as a privacy screen. I will be planting along the south fence line of my property; however, the fence line itself is already planted with Chinese privet trees (ugh) that can't be removed, so anything I plant may get some shade from these trees. I'm looking for something 5-6 feet tall that will provide a sight barrier without getting too bushy (I don't want it to intrude too far into my yard). Native and/or pollinator-friendly would be a big plus! Any thoughts?
- Hello there, too bad about the privet but your planting will help to bring some pollinators and wildlife into your garden. The first shrub that comes to mind is inkberry (Ilex glabra). There are many varieties of this plant out there with different mature heights. So when shopping be very careful to read the tag and ask questions about the ultimate height and width of the plant you are choosing. The plant is evergreen and has small white flowers (not terribly noticeable) in spring that develop into small dark blue to black berries. Other native choices are mountain laurel (Kalmia latifolia) and evergreen bayberry (Morella caroliniensis). Mountain laurel can grow to 12 feet or more but can also be pruned to control height and create a bushier shrub. It has beautiful blooms in spring and is evergreen. It does like some shade so maybe the privet will help with that. It does not like clay soil. Bayberry is also evergreen and can mature around 7-10 feet. It's not too particular about soils and can take shade. It has small flowers that develop into those waxy gray blue berries most people are familiar with. All these choices are native and will attract pollinators and wildlife. Best of luck with your project!
