Pollen Sources

Is there a source near the Denver area where I can buy pollen, to hand-pollenate my backyard fruit trees? I have a Bing cherry and a Honeycrisp apple. I don't think there are others anywhere near my home, so I'll probably have to pollenate them myself.

Thank you for taking the time to consider and respond to my inquiry.

New growth on bareroot fruit trees?

In March, I planted several bareroot apple trees. Each are approximately 3-4' tall. One has growth at top of the trunk, but several others have growth near the base of the tree. This growth appears to be above the graft. Should this growth be removed, or allowed to grow? If the existing trunk does not recover, should it be pruned down? Thank you!

Black WAlnut/juglone

I have bought a home in Trinidad with a huge black walnut tree. I’ve discovered that it puts out juglone, which is toxic to many plants. W hat can safely plant beneath it? The planting area is probably only 15’ x 30’, and I understand the roots extend 50’ to 80’.

soil testing

I'd like to bring a soil sample in for testing. I have lost a red maple, an arborvitae, and a dogwood -- all within a 10 foot radius. I'm thinking that the sewer lines may be ruptured or leaking even though I don't have any problems with the toilets in the house. In the past I have used your services for Ph testing of the soil in my garden.

Weed identification

Our backyard backs up to a small pond and there are some kind of plant/weed that is in the shore area of the pond and has spread into our yard. It seems to have a thick root and spreads quickly. When it seems to be full grown, it is about 6' tall. We have included a picture up close of what it looks like when it starts growing and also when full grown. We are wanting to see if it can be identified and determined what we can do to get rid of it without harming our lawn or the pond.

Colorado Proven

I am an Oklahoma OSU Extension Master Gardener, visiting my son in Colorado Springs. I'll be here about 3 weeks and one goal is to help them get their backyard presentable. I am unfamiliar with the growing season and plant selections in this area. Do you have a fact sheet or publication that lists Colorado proven plants? I'm looking mostly for low growing shrubs and perennials that are low maintenance (for obvious reasons) :)
Any help is appreciated.
Edit: I've decided to put 3, hardy, dwarf (6-8'), colorful trees along the back fence. Suggestions appreciated.

What is this and where can I buy more

This plant grew in our garden a couple of years ago. We are not sure how it got there, birds or wild flower seeds perhaps. I have take a picture to Gertens and several other places and no one knows anything about it. It is about 4 ft tall, red tubular flowers, fern like leaves. The hummingbirds and butterflies love it. Please help.

Mystery Disappearance

This morning while checking flower beds I noticed one of Japanese Lily plants was missing. Planted this spring 3 plants, two doing great, but third was not flourishing as much. Well this morning it was completely gone. Hole looks like it was pulled up not pull down. Is in courtyard with no signs of gophers or similar creatures. Do have gray squirrels. Could they be at fault? What can I do to prevent? Thank you

Lawn Moss

I live in West Lakeland and outside of fighting Buckthorn we have enjoyed the area these past thirty years. Our place has very large Red and White Oak trees that yield a lot of shade. My problem now is yard moss that is growing everywhere even in sunny spots some places it feels like you are walking on sponges. The last few years the problem has increased considerably.

Arbor Vitae

We live on Lake Michigan so we get very cold winds. I put up a snow fence this winter to protect my trees from deer, etc. The arbor vitae is healthy on top but dead up to about where the snow fence was. There was no salt, etc. there. Would you have any ideas of what may have happened and if I need to get rid of it and replant something hardier to have a full plant to the ground again? If so what would you recommend that is that cylinder shape?
Thank you.
