round up

Is it a normal practice to use roundup on grain crops to time the harvest for consistancy and moisture content?

I realize this question should not have been asked in this forum. Sorry.

Italian plum died - suckers continue

How do I deal with continueing suckers? given your reply -More than likely, your Italian plum was grafted onto a root stock, which provides hardiness and growth regulation, but is not the tree you selected for the fruit production. These suckers may or may not be an edible plum (sometimes they use other Prunus). I would not recommend that you train the suckers, as it will likely never result in a nice tree. Plus, root suckers can be structurally unsound, since they are generated from root systems.

Unfortunately, it sounds like you will have to replant.

We have Arborvitae that are planted in the SE corner of our backyard, they get filtered sun and also are partially covered by Fir tree limbs that hang over our fence. They were planted last year around August 2014. We have been told Arborvitae needs full sun, is this correct, do you have any suggestion as to what the problem might be. We want to replant but are not sure if this is the right location for them

tree bark removed

A small boy, old enough to know better, though, has peeled away an area of bark on the trunk of my conifer - about six inches in diameter. I can see sap oozing out. Is there something I should put on to protect it? He also peeled completely around a two inch segment from a branch near the main trunk of my medium sized Japanese maple tree. Will that branch survive? Thanks for your help! Pat

60 year old 75ft Doug fir w/pitch eruption

Abt 4 months ago my Doug fir (w/diameter of abt 4ft) suddenly on its SE side developed a very large eruption of pitch (abt 35ft from the ground) a 10ft long flow, abt 8" wide at the outflow, widening to abt 27". The pitch is thick looks dry (whitish) and looks as if there have been several eruptions. For 20 yrs a doghouse (4ft x 4ft) sat abt 2 1/2 feet from trunk on the NE side. The last 3 -4 yrs, has seen an increase of broken, nude, lower limbs on the Doug's east side. We got rid of the doghouse a few weeks ago. I can't see any physical reason for this waterfall of pitch, and I am worried as the tree is a close and valued friend of many years. Please help. What could cause this belching of pitch? What can I do to help the Doug? I appreciate any info or answers.

My rhododendrun’s do not bloom!! Maybe I will see a scanty bloom here and there (short lived). They are planted on the NE side of my house and get morning sun now. They have been in planted in my yard for over 20 years. I have given them rhodie food. I see buds but they don’t produce the beautiful rhododendron flower. What could be my problem? Thank you for your help. ~ Barbara~ Sent from myMail for iOS
