Q. Can I Grow Contorted Hazelnut Tree in Container

Can I grow a Contorted Hazelnut tree in a container? If so, what size container would I need? I’m told the tree grows roughly 8-10 feet tall.

Anything can be grown in containers as long as you can give them enough water (and provide adequate drainage), light and food. This article should help: https://www.gardeningknowhow.com/ornamental/trees/tgen/growing-trees-in-containers.htm

Q. Dogwood and Hazelnut Trees

When planting new dogwoods, how deep (I’ve raised them from ‘twigs’ and they have no ‘rootballs’) should they be planted? I’m in the middle of nowhere on the side of a mountain. I have a well, septic sand mound,  two vernal ponds and LOTS of water (depending on the season), wildlife and four dogs. What is the root depth for these trees? How about buildings, foundations, crawl spaces, etc? I want to ‘permanentize’ these — all have endured a ‘touch-n-go’ young life.

You will want to plant them at the same level they are at now. The roots will grow down a few feet, but dogwoods are pretty non-invasive with their roots, which is why they are frequently used as foundation trees. There is little chance they will harm any walls or foundations near them.

Q. Grub worms

Grub worm is becoming one of the most root pest issues in my hazelnut plants. Therefore, is there any solution other than nematodes?

Root maggots are not a common pest of hazelnut trees, so there isn't much information. This article might be of some use: https://www.gardeningknowhow.com/plant-problems/pests/root-eating-insects-identifying-vegetable-root-maggots-and-root-maggot-control.htm
A bT product might work for you: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/using-bacillus-thuringiensis.htm
If you have any horticultural resources available to you, through a nearby university, botanical garden, or government dept of agriculture, you might look there for information on this pest and its control.

Q. Corkscrew Hazel

I have a corkscrew hazel growing in a pot (garden is small). It started off well last year but this year all leaves curled up and dried out. I sprayed with a ‘bug killer’ for various bugs and have added phosphate to water, but didn’t seem to help much. No leaves now but tiny buds appearing, though they don’t seem to grow much before dying off. Help!!

I don't have any experience with this plant, but since doing research for your question, I'm dying to try it myself. Go to this site: http://homeguides.sfgate.com/care-transplant-corkscrew-hazel-tree-86594.html -- Sorry, I couldn't get it to come in as a link, but the information is very useful. I hope it helps to fix your problem. Happy Gardening!

Q. hazelnut tree watering

How often should I water my plant transferred from ground to pot? I transferred a hazelnut plant from ground to pot. I live in California San Bernardino Mountains. Climate in spring is mild, about 65 to 75, and in summer 85 to 95 degrees.

I would keep the soil consistently moist, but not damp/soggy - be careful not to over-water. You should never let the soil of a hazelnut dry out completely. The soil you use should be well-draining.

Q. leaves turning yellow and brown

The leaves on my hazelnut trees and my grape vine are turning yellow and brown. The growth is much less vigorous. My honeysuckle also seems to be less vigorous. Can I save them? The honeysuckle and grape vine are 5 years old and the hazel is only one year old.

Since both planting are showing signs of the same browning leaves it would indicate an insect or fungus issue.
Examine the leaves and plants carefully to see if you can identify any pests or signs of fungal disease.
You can treat with Neem OIl as is does work as both an insecticide and fungicide.

Q. Twisted filbert tree

How deep do I plant it and to keep it small, do I keep it in a container when I plant it or just keep it pruned?

Dig a hold that is 3 to 4 times wider then the pot and plant the tree as deep as it was in the pot.
Make sure you do not damage the roots while removing from the pot and backfill with the soil from the hole. Do not add foreign soil.
Add 3 inches of mulch to help with moisture retention.
Keep the soil moist for the first year. 2nd year water when the soil is dry.
Watering deeply once a week is preferable.

A container planting is not recommended for this tree.
