Do you have an office that does testing of the seals on pressure canners. If so where is it located and do I have to make an appointment

I was given a wood slab supposedly from an ancient tree. Apparently this tree the grain runs longitudinally up and down the tree rather than in rings around the tree. Moreover, this tree has a less than substantial root system. To store moisture, this tree actually sewlls up soaking up moisture and expanding to store the moisture for dry times. Did or does such a tree exist? If not what kind of wood do I have a slab from?

I live in Gambier OH Zone 5. I want to grow seedless concord grapes. The seller says only up to zone 6. since concords do well here, is that correct?

I see Euonymus alatus Burning bush is listed on the invasive plant species.  Is it ok to use the Euonymus japonicus 'Green Spire' as a good and safe alternative for a 9' tall evergreen hedge?  Is it likely that in time this too will be placed on the invasive plant list?  I also looked at the  E. kiautschovicus 'Manhattan' but I see it is not likely to reach the desired height and is susceptible to Euonymous scale. I considered Boxwood but there does seem to be a lot of Boxwood blight around, so ruled that out unless you have other information.   I'd welcome your advice and recommendations. Thank you.

My lawn is full of creeping buttercup. Can I kill it by covering my lawn with newspaper and then a layer of mulch? Can it still survive under cover?

What cruel animal could have so wantonly and recklessly striped the bark off my poor tree?

Would you recommend a tomato variety for the Colorado front range please?

I have planted two tomato vines in large well drained pots for the last three years with terrible results. I tried what I thought was a hot weather variety this year thinking I would get better results. The plants had plenty of blooms but no tomatoes this hot summer. Once it turned off cooler, I began to get tomatoes and, in fact, having brought the plants indoor now have six large tomatoes growing on one vine.

Clearly I need a tomato variety for these hot 90 degree days and, perhaps, for this Brighton, CO altitude.

Any recommendations?

Thanks,

Clark

Hello, I have a question about what plant you would recommend for growing in my yard that is very strongly evergreen scented and that doesn't get too big. One that could also tolerate partial shade would be good but not necessary. I've been looking into Alaska cedar or Leyland Cypress but could use some expert advice. Thanks!

Hello, I have a question about the large little leaf linden trees that grow in the parkway in front of my house. I notice that it is very hard to grow grass or other plants under them. My guess is that they make lots of shade and have shallow roots that compete for moisture. But I am wondering if they have any other effects on the soil such as allelopathy, etc. I notice all my neighbors have this same issue. Just wondering if there is a way to eventually grow some healthy plants near these trees. Thanks!

I have had these for several years and they do bloom. I dug them up thinking that there might be weeds creating a problem. What should I do with these if I want to get them to bloom? I appreciate your help.
