Philodendon with Root Rot

    Date Posted: Thu, Jun 15 - 11:35 am

    Question

  • Hello, I have a Philodendron Deja Vu. It has shed all but one remaining leaf, which appears to be getting too dry. It has three root sections (not sure the proper word) the other too appear to have some root rot. Is it possible to repot the section with the one remaining leaf? Is there anything else I can do to help it survive and thrive again or is it a goner?
  • Answer

  • Hello, I'm sorry to hear your philodendron is struggling. Based off of what you have said, I'm concerned the plant may be getting over watered leading to leaf spot and/or root rot. Leaf spot is common with philodendrons and starts with leaves turning yellow and then eventually brown. Typically, it is due to damp and soggy soil from over watering that allows bacteria and fungus to thrive. To treat this, stop watering the plant and apply two spoons of baking soda mixed with soap water on the affected parts and keep the plant out of direct sunlight. Soggy soil can also lead to root rot. The best way to treat root rot is to change the soil immediately and be sure to use a well draining soil mix (similar to what you would use for a cactus). Let the soil dry out some in between waterings, using the finger knuckle test to determine if the plant needs water or not. Most of our local plant nursery's also have extremely helpful staff members that will look at your plant if you bring it in and make more specific suggestions, or even repot it for you. Good luck!

Pests

    Question

  • What's wrong with my tomatoes? I've been gardening for years, but have never seen this issue with tomatoes before. This is my first time gardening in Hanover, VA. I believe the space has been used for gardening before. I didn't do a soil test. The only soil amendment has been bloodmeal. All of my tomatoes, regardless of size, look fine while green, but as they ripen, they appear to have white spots underneath the skin. When I cut them open, they all have a sort of white pithiness throughout the outer flesh just under the skin. The flavor is okay but the skins are tough and crunchy, and it's consistent throughout the 6 varieties I've planted. I haven't seen any issues with the foliage. I'm really stumped on this one but I am wondering if this is a new-to-me disease or an outcome of inconsistent watering (due to some unforeseen circumstances, they're largely surviving on what falls from the sky plus one weekly watering). I saw a few earlier in the season that have blossom end rot, but these ones don't have decay at the blossom end. Any thoughts? Thanks for your insights!
  • Answer

  • Hello there, this does sound discouraging!! I have to admit that I have never had this issue but I did a little research and found some resources that may help you. The first website is from Texas A&M. It's useful because it shows pictures of ripe fruit in trouble and identifies the problem. I'm making a guess that Cloudy Spot might be your issue. Of course, I must emphasize that this is a guess, having never seen the problem you describe firsthand. Cloudy Spot indicates stink bug infestation--https://aggie-horticulture.tamu.edu/vegetable/problem-solvers/tomato-problem-solver/ripe-fruit/. If that's right, the VA Tech website has a video on how to trap the culprit--https://vtx.vt.edu/articles/2019/10/Stink_bug_Media_Advisory2019.html, I like this solution because there is no chemical insecticide involved. The trap in the video was created to trap the bugs in homes but can easily be used in the garden as well. If my guess is wrong, you have another option. VA Tech has a plant disease clinic where samples can be tested and identified. Because Richmond City does not currently have an extension agent due to a staffing vacancy, you can contact the Chesterfield office and get the details on submitting samples. There is a $35 fee as well as paperwork that must be submitted with the sample(s). You can contact them at this email address-- Chesterfield MG Help Desk: vce@chesterfield.gov. Best of luck sorting this out!!

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!

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.

Yellow Spots on Rhododendron Leaves

    Date Posted: Wed, Aug 18 - 2:01 pm

    Question

  • My large rhododendrons have some yellow specked leaves. Been watering every other day. What are you suggestions
  • Answer

  • Hello! Thanks for your question. Given our recent warm and humid weather conditions, the problem you are having with your rhododendron is certainly not uncommon. I suspect your plant has a fungal condition called leaf septoria (yellow leaf spot). It sounds as though the condition on your plants is not widespread at this point and there are a few steps you should take to rid your plants of this fungus. First, remove the affected leaves to get rid of as many fungal spores as possible. Secondly, take away any fallen leaves from under the plant and keep the area clean. Discard all removed leaves in the trash (not compost). Mulch the area under your rhododendrons; this helps prevent spores from spreading. It will also help retain/absorb the water when you are watering the plants, and reduce splash upwards. And when you water, it’s best to use a soaker hose at the base of your plants, versus overhead watering. Watering overhead and watering in the evening can increase fungal disease development on these plants. You can also apply a simple, all natural spray solution consisting of the following: one quart of water in spray bottle with 1 teaspoon of baking soda; add 1/2 teaspoon of canola oil and a few drops of dish soap; shake the solution well and spray on the plants. Good luck with this - improved weather conditions in the coming weeks hopefully will help as well! Let us know if you have further questions. Thanks! And of course keep a close eye on your other grow bags with your other vegetables for any similar signs. Good luck with your garden, and wishing you a strong yield!

Lawn options-seed or sod

    Date Posted: Wed, Aug 18 - 2:00 pm

    Question

  • I’m trying to decide what to do about my front lawn. It’s a little under 60 square yards. Everything is killed off and tarps are covering the ground now to keep weeds from growing. There is no shade, all day sun. I would like to know if Tall Fescue is the best choice and also should I seed or sod. Cost is not the issue since it’s a small area. I hope you can give me some advice.
  • Answer

  • Well, I know you didn’t ask this but what about foregoing a lawn and planting a dooryard garden instead?. I’m not much of a grass person. A patch of clover is more to my liking, at least it gives the honey bees a place to land, adds some nitrogen to the soil. Maybe a combination of a lovely shrub border, a small tree, a mix of tall and low-growing perennials, groundcovers? Since it's a small area the expense wouldn’t be staggering and you can always phase in the plantings. Something to consider.... That being said, I think you’re doing a good job of preparing for a fall planting by covering the space and killing off the weeds. If I haven't persuaded you to take a different approach, I’ll try to answer your question about seed or sod. You didn't mention why your lawn was "killed off". Is there an issue with the soil? If so, you should request a soil test kit from the Richmond VA Cooperative Extension Main Office: (804) 786-4150. The results will let you know what, if any, amendments you'll need to add. I think the choice of a tall fescue is fine and fall is a good time to start a cool-season grass. When purchasing seed, check the bag to make sure you are buying all seed and no filler. Look for the two Virginia-Maryland labels affixed to the package so you know you are buying seed mixtures or blends which comply with the quality standards of the Extension Divisions of Virginia Tech and U of MD. First, you'll need to prep the soil. Remove all the dead weeds you've killed by covering and make sure there are no roots left in the ground. This can be tedious but it will pay off in the long run. Work in any amendments your soil test dictates. Add a layer of compost, you can till it in, or if your soil isn't compacted, adding 1-2 inches to the surface should suffice. Grade the soil with a rake so the surface is smooth and uniform. At this point you can seed. Disburse the seed with a spreader and go back and forth across the lawn, then in a perpendicular direction, attempting to get an even amount of seed across the surface of the lawn. You can add another fine layer of compost so that there is good contact between the seed and soil. (For a larger lawn you would roll the seed at this point.) Then you'll need to water immediately thereafter and continue to water until the seed germinates. (Be careful when watering, keep the soil moist, don't wash the seed away.) After that a total of 1-2 inches of water a week should keep the grass in good spirits. Hand pull weeds. An established lawn could take up to 2 years with seed. If this doesn't sound like fun, you can clean up the soil as above, amend as needed, grade it with a rake, and lay sod. Do not let the sod dry out. You'll need to water the sod daily for a couple of weeks (of course, less if there's rain). During this period the sod will be putting down shallow roots into your soil bed. Avoid walking on the sod during this period. After about a month the sod will have established a better root system. Around this time it will need to be mowed. Set the mower to 3 inches. The sod will provide a quicker route to a nice green lawn if the expense is acceptable. I hope I've covered all your options. Good luck with the project!

Watering roses

    Date Posted: Wed, Aug 18 - 1:48 pm

    Question

  • Hi i have a row of drift roses on the front on my yard, they are in full sun. I had been watering them every other day with the lawn but noticed that a few bushes had yellowing leaves which then turned brown and crispy. I am assuming that is a sign of being overwatered? Any suggestions on how to make the flowers last so they don’t turn brown so quickly in the heat? Thanks!
  • Answer

  • Hello there, My first instinct is that you are, in fact, over watering your roses. How long have the roses been planted? If it's been a few years then watering once or twice a week should be sufficient. Is the soil well draining? Roses don't want to sit in consistently wet soil. Are you able to gauge how much water, in inches, your roses are receiving. one to 2 inches of water (rain+water combined) should keep them healthy. I believe that's about 4-5 gallons of water a week. Also, I don't think the heat is causing the roses to brown but the effects of over watering are. Back off on the watering a bit. Try to avoid the foliage and water the soil around the plants and see that they get soaked rather than sprinkled. I suspect that less water weekly (avoiding the foliage whenever possible) and a couple of good soaks a week will make you and your roses happier. Good luck!

Yellowing Aster

    Date Posted: Wed, Aug 18 - 1:46 pm

    Question

  • Hi we have a row of fall aster and notice that this year and last as the rest of the plant grows large and bushy the base starts to get yellow and then dries. the plant seems to be getting enough water. Is this normal?
  • Answer

  • Good morning, and thank you for your question! My first thought is that you may have a watering issue. I’m assuming your aster plants otherwise have normal growth, are not stunted, and bloom well. Asters do prefer well-draining soil and like to keep well watered. However, they do not like overhead watering or sprinkling. Doing so can result in development of a fungal disease. Watering should be done at the base of the plant where fungus would first develop. It also helps to use a good organic mulch around your aster plants to help retain moisture and prevent splash to the lower leaves which can cause the yellowing. As a side note, be on the lookout for leafhoppers on your aster. They can spread bacterial disease (phytoplasma), which is a more serious problem to deal with, but with this you would likely notice other symptoms such as stunted growth and deformed flowers as well. If those symptoms develop, the plants would need to be removed as there is no cure. It does not sound like you are experiencing these specific problems with your aster, and proper watering and mulching would be the best first steps to implement. Good luck with this, and let us know if further symptoms develop.

Majesty Palm dying

    Date Posted: Tue, Aug 17 - 8:40 pm

    Question

  • I have a majesty palm that sits in a corner by my living room windows. It doesn't get very much light there (but I don't have anywhere else to put it) so I added a growth light. The light delivers red and blue light for 4/hrs every night and is set up about 5 feet away. I also have a terracotta automatic water in the soil, which keeps the soil most without being soggy. Nonetheless, the plant is dying. The fronds have been turning brown from the outside in and now I've had to cut away two complete fronds which and a third is on the verge of death. What am I doing wrong and is there anything I can do to still save it?
  • Answer

  • Majesty palms are very particular about the level of light required, but it sounds like you are dealing with that effectively with the grow light. One factor you did not mention was your soil. These plants require very well aerated, loose soil which drains well. Make sure your soil is not too dense, particularly since you are irrigating with terra-cotta automatic watering. I have three majesty palms and all are sitting in north facing windows. They are getting only indirect light all day. One of them was initially in densely packed soil, and was not doing well, so I repotted in a very loose soil and the palm seems much happier. Also, these plants love to be fed. I use a miracle-gro continuous release palm plant food, so you may want to try that.

Tomato-Blossom End Rot

    Date Posted: Tue, Aug 17 - 8:37 pm

    Question

  • I'm just starting to see fruit on my tomato vines, but unfortunately they look to already be developing blossom end rot. I'm using a mixture of organic soil with fertilizer and perlite, and I'm not sure if the plant is salvageable. What can I do to help this plant? And what advice can you give for other tomato plants to prevent this blossom end rot? Is there something I can apply early on to prevent this? Thanks!
  • Answer

  • Hello there, This is a pretty standard issue with tomatoes. Generally, the cause is inconsistent watering and/or a calcium deficiency. So the first step would be to establish a consistent level of watering for your plants. Of course, Mother Nature plays a role here as well, you can't control that. If you're sure that watering is not the problem, then you need to think about calcium. Without testing the soil you won't know the level of deficiency. But if you want to proceed, there is a short-term fix. I haven't tried this myself because the cause for me was generally a watering issue, but you can spray the plant with a calcium solution. That will buy you some time to increase the calcium content in your soil. There may be enough calcium in the soil but the ph of the soil may be preventing the plant from absorbing it. I don't understand all the chemistry of this but soil ph is the root of plant happiness. A ph of around 6.5 will do. Try adding some fast-acting lime (don't use dolomitic lime) and working that into the soil about 12 inches deep.The lime frees up the calcium from the soil. As I said previously about chemistry....This is a time-honored practice so it should work for you if, in fact, you find that watering is not the problem. If you would like to have a soil profile done, please let us know and we can send you a soil test request kit. Good luck with the tomato harvest!
