We have a maple tree in our front yard, facing south. We have a maple tree (type?) that lately has been leaking black stuff on our sidewalk. Does it need to be cut down?

A maple tree leaking black sap could indicate several issues, including fungal cankers, bacterial wetwood, or insect infestations. Black sap is often associated with diseases or conditions that damage the tree’s tissues, such as slime flux (bacterial wetwood) or bleeding canker, which are visible as dark sap or slime oozing from the bark.
Here’s a more detailed breakdown of possible causes and what to do:
Possible Causes:
· Bacterial Wetwood (Slime Flux):
This condition is caused by bacteria entering the tree through wounds, producing a slimy, blackish ooze and potentially fermenting into alcohol.
· Fungal Cankers:
Cankers are lesions on the bark caused by fungi or bacteria, and can ooze dark sap.
· Insect Infestations:
Certain insects, like aphids, can feed on the tree’s sap, causing a sticky, sugary substance that can attract ants and other insects.
· Bleeding Canker:
This is a disease that causes cankers on the tree’s trunk, often accompanied by dark brown or black sap.
What to do:
· Identify the Cause:
Observe the tree closely for signs like dark spots, cankers, or insect activity.
· Remove Cankers:
If the tree has cankers, carefully remove them and treat the wound with a 10% bleach and water solution and then use an ‘end cut’ product to cover the wound.
· Address Insect Infestations:
If insects are the problem, try organic solutions like soap and water or dormant oil. If you want to use dormant oil the window closing quickly and you would need to do it now.
· Manage Stress Factors:
Ensure the tree has adequate water and sunlight, and consider fertilizing if needed. Trees under stress are more vulnerable to disease and insect infestations.

Hi there! I want to add a large plant/shrub in my partial shade garden. I live near a lot of deer traffic – must be deer resistant. I have lilacs, hostas, and 2 oak trees nearby.

Try a barberry.

Need about 10 feet of plastic edge with large roll, and the joiner pieces to repair some lawnmower damage and shifting separation. Do you sell that

We do sell landscape edging however we do not sell the roll variety but rather the industrial grade 20’ lengths. If you come down we may have some lose ends left over from a project and could help out with a smaller piece however that’s all dependent on if we have any extra. Otherwise you’d need to buy a 20’ piece. It does come with a connector and stakes though and extra of both are available.

Do you sell emerald green arbovitae evergreens?If so, what’s the tallest ones that u sell?Looking to create a privacy fence and would prefer trees that have some excellent height already.Cost per tree?Thank you!

We do not sell Emerald cedars as they do not live in our climate. We do have Brandon cedars, Siberian cedars, Holmstrups cedar and spire cedars which can be used to make a nice fence/hedge. Each comes in varying sizes and price points. Best to chose your crop based on the length and the width you have to work with and then we can help you.

Follow this link and type in the names of the crops mentioned above to see the heights and widths available and that will drive your decision OR call the store and we can walk you through the process based on the detail you provide.
