    Watering Carmel creeper plants #889459

    Asked November 06, 2024, 7:31 PM EST

    I have received three different ways to water my Carmel creeper plants. First I was told that the only way to water was by soaker hose. Then I was told to water by hand. I wanted to do a drip system, but was told not to do that because it would cause root rot. My gardener also said to do a drip system. Would appreciate a response. Additionally it would be on a sprinkler system so how long to water and what size of emitter. The plants are on a hill and the purpose is to have them grow to prevent erosion. Thank you in advance for your assistance.

    Oak wilt status still at "Caution"? #889455

    Asked November 06, 2024, 5:58 PM EST

    Hi! I see on your website it still says (11/6/24) the oak wilt status is "Use Caution". Is this correct? We are still not safe to prune oaks? Last year the status changed to "safe" in mid October.

    Maple tree bark #889452

    Asked November 06, 2024, 4:52 PM EST

    Why is the bark on my Maple tree growing in long strips that now stick out from the trunk? This seems to be a recent change. The tree is mature (more than 25 years old) and in a sunny location. Picture included. There are several of these big strips around the trunk. They are not detached -- very sturdy, but sticking out from the trunk in long strips.

    Green Giant Arborvitae Browning #889432

    Asked November 06, 2024, 12:40 PM EST

    These trees were planted about 3 years ago and this is the first time I have noticed this browning on the interior needles. It was only about a month ago that I first saw something on one of them, but now it’s on all of them and appears to be getting worse. It is definitely only in the interior needles closest to the trunk and I would say mostly on the shadier side of the tree stand. What do you think is going on here? Is the browning anything to worry about and if so anything I can/should do? Thanks!

    deer damaged young tree #889431

    Asked November 06, 2024, 12:04 PM EST

    We recently moved from CO to Marshall. The deer are really hard on landscape plants. They wreak havoc on new landscape plantings, but beyond nibbling leaves they had been leaving the tree transplants alone. However; last week they tore apart our weeping Japanese maple (attached a couple of pictures). I think it will survive but my question is whether I should do anything to help it survive (e.g. wrap the damaged trunk or put [tar] on the damaged bark)
