Is K "per year" like N?

We have our lawn analysis (492F44). It indicates the amounts of K and N needed. The timing chart for N says "per year," but the K recommendation does not specify a time frame. Is it correct to assume a "per year" application for the K recommendation, too?

garden question

Our tomatoes had a blight/fungus this year. Any suggestions on next year? Do I have to treat the ground with something. A farm supply told me to treat the plants next year with a copper fungicide. I really don't want to spray the plants with chemicals.
Any suggestions?
Thank you.

White oak sudden death - black underneath of bark

Hi! I have a tree that died suddenly in our backyard - a large white oak. It's very upsetting because it was so sudden.

We had a few large branches that were dying removed -- they were over the house. Just a few months later, another branch that a swing was attached to died.

We held off a few weeks on getting that branch removed because we had just had others removed and it wasn't in danger of falling on anything.

Then, within a course of 1-2 weeks, the bark started to fall off in large pieces with black showing underneath (see photo). We had the swing branch removed to try to help the tree, but the tree service reported that the tree was going to die.

Others have said it's not dead and we should hold off cutting down the tree because it could bounce back. I have attached photos of the tree.

All the leaves appear dead on the tree now. It has a sister tree right behind it which is doing fine except some sap bubbling out of one spot in the bark. The bark does looks a little darkened and damp in places, but it hasn't lost any branches or bark and the leaves appear fine. Our back yard is generally shady and moist -- lots of moss.

I have three questions:

  • Is the first tree past gone based on the photo? If not, what can I do?
  • Should I be concerned about the second tree nearby (could it catch the fungus or whatever from the first tree)?
  • Should I remove the first to save the second? What can I do to prevent this from happening to the second tree?

Having the first tree removed will obviously be very costly so I would ordinarily wait to have it removed, but I will try to remove it as soon as possible if it helps the second tree.

Thanks very much for your assistance!

We are sad to lose our first tree and want to help the second one if possible.

Best, Audrey

Death of an Oak Tree?

We have a large oak tree that in less than a month has gone from healthy green leaves to almost all leaves being brown and dead. This is in the middle of summer while a sister oak right next to it is perfectly healthy. Any idea what might have caused this? Can anything at all be done to try and save it?

Fertilizing native spruce, aspen, chokecherry

Hi,

I live in Fraser, CO, at an elevation of ~8800'. Our winters are, as I'm sure you are aware, brutally cold and long. I have extensive landscaping, consisting primarily of native species; e.g., Colorado spruce, aspen, Canada red chokecherry, twinberry, serviceberry, dogwood, etc. I have fertilized in the past, but would like to know your thoughts on this; i.e., what ratio fertilizer (same for all or different), liquid or otherwise, particular brand, when and where? Thank you very much. Greg Horstman

Headspace in jars

I can tomatoes from my garden. With all i've read about the variance of acid in the tomatoes I've gone with a pressure canner to minimize the possible issues with that factor in canning. What I've found on 2 of my batches is after processing my jars have more headspace than intended and I can't find a well referenced answer to tell me if this is an issue. The recipe called for 1" of headspace and several jars now appear 1 1/2" I have checked the seals and there appears no issue with a good seal on the lid. Can you advise if the excess headspace means this batch can't be put up? thankyou

Also, I should add that my front yard faces south, it is open to wind and sun since nothing nearby shades it.

I am looking for one specimen/shade tree for my small(but not tiny) front yard. I'd like it to shade my house but not grow so tall so that it would be a danger to my house. I think 20'-30'would be ideal. The front of my house is taupe & almost plum colored brick. Someone suggested several possiblities for me and I went off to a nursery. I decided on Syringa reticulata '? Snow' cultivar. The salesperson said that they only carry plants that are suitable for our area. However,after coming home, I looked it up and read that in Zone 7 & higher that the "leaves emerge early & often desiccate or become necrotic by mid to late summer, not a good doer in the heat of a southern summer. " My question to you is that do you know of any planted in our area and how are they doing? They are scheduled to plant this /Saturday. I know that you are busy, but if you could respond fairly soon, I would appreciate it greatly.

Painting the Outside of Wood Raised Beds

We always have done organic gardening, but as the years go by, we are less able to work a large garden. We are now going to build raised bed vegetable boxes which will be on the deck of our home and will be visible from the street. Three questions: 1. If we paint the outside of the boxes, but not the inside, will chemicals still leach into the soil? 2. Is food grade plastic for the liner, a safe alternative? 3: Are Earth Boxes and Grow Boxes (that are available for sale) safe for organic gardening?

I have a Northern Red Oak in my front yard that appears to be slowly dying....

I have a Northern Red Oak in my front yard that appears to be slowly dying. The tree is about 12" in diameter at the base. It is pretty well established. This year it seemed to leaf out rather thinly. Other than that it looked okay. Midway through the summer one of the lower branches started to brown on all of the leaves and then turned completely brown and dead. This branch was right at the top of a frost crack suffered some years earlier. I thought this to be the reason. Several weeks later another branch up in the middle of the tree did the same. Now another branch on the other side is starting to do the same. Is my tree dying? Is there anything that can be done? Ron

Please help identify this weed. I used round up 5 weeks ago to restart my yard. Last Saturday (8/30) I dethatched to about 1/2", removed the thatch, amended my soil per my soil test results. About Tuesday or Wednesday I started noticing this weed. Now the weed is fairly dense as you can see in the picture. I did notice my neighbor's established weedy yard also contains the same weed that is about the same size. Do you know what it is and if it is a concern with my new grass?
