Question 1

When shouldn't you prune trees?

Accepted Answer

•

Pruning trees during the summer can be a bad idea because the new growth will take place during the hottest months of the year, which can stress your tree out. Similarly, pruning during the early fall can be a bad idea, too, because you’d be stimulating new growth when most trees are aiming to go dormant.

Pruning recommendations will vary by the type of tree, but generally, waiting until winter to prune your trees is a good idea.

Question 2

Is hiring an arborist worth it, or can I hire a standard tree company?

Accepted Answer

•

Hiring an arborist is usually more expensive than hiring a standard tree company, but it’s typically well worth the investment. If you suspect a tree is infested or diseased, hiring an arborist can help avoid the same fate for nearby trees, and prevent removal. Arborists might also be necessary if you’re dealing with tree removal or trimming near power lines, as uncertified removal companies often aren’t permitted to service these trees. Finally, if your aim is to preserve the health of your trees, an arborist is absolutely worth the money.

Question 3

How long should I water a tree?

Accepted Answer

•

How often and long you should water a tree depends on the species and if it is mature or newly planted. The amount of water is also based on the tree's size. A good rule of thumb is approximately 5 gallons per inch of the trunk's diameter.

Adjusting watering to the recommended suggestions for the tree type and weather conditions is vital. For instance, watering trees during a drought is necessary, and you may need to water more frequently than usual.

Question 4

Does Dutch elm disease affect other trees?

Accepted Answer

•

It’s not as common for Dutch elm disease to affect other types of trees, especially if the surrounding trees aren’t elms. However, it is possible for DED to spread to other trees, particularly in northern states, like Minnesota. In fact, it’s a good idea to use geography to identify wood and determine which types of trees are in your yard.

Unfortunately, the complex and shallow root system of elm trees makes surrounding elm trees particularly vulnerable to DED. Early discovery is key!

Question 5

Can forestry mulching grind stumps?

Accepted Answer

•

Yes, forestry mulching can grind stumps, but the level of effectiveness depends on the equipment used. Drum mulchers can break down smaller stumps, but larger or deep-rooted stumps may require a dedicated stump grinder for complete removal. If full stump removal is necessary for replanting or construction, additional excavation may be needed. Always check with your forestry mulching provider to confirm whether they offer stump grinding and if their equipment is suitable for your specific needs.
