Dennis says: It’s time to prune your roses

2 weeks, 2 days ago Tip of the Week

Roses have long been a popular plant in the landscape. The use of roses has changed dramatically over the last 10 to 20 years as we have moved from growing the large flowering hybrid teas to the easy care shrub roses. No matter what type you grow both types benefit from proper pruning in the early spring, just as growth is starting. To read more … Continues »

Plum trees 2

What to do about oddly shaped plum tree?

2 weeks, 6 days ago Q&A

I have two fruiting plum trees (see photo) that were planted on the same fall day about 3 years ago. At the time, they were the same size. You can see one of them has grown very nicely and has a nice shape. The other has never really done all that great. It has a very odd shape and suffers a lot when we have high winds. I’ve had to pluck green plums off of it because they will weigh it down almost to the point it touches the ground. What can I do to help the little one out? Or is it a lost cause? I can’t for the life of me figure out if or how I should prune it to help encourage it to grow in to a stronger tree. Or should I just cut my losses and try to re-plant? - Mitch - Continues »

Raised bed? 2

Raised garden bed: Will this work?

3 weeks ago Q&A

Hello! So I need some guidance. This year my spouse and I would like to build a small raised bed on the side of our house for herbs and possibly a vegetable or two. The side of the house that we would like to build it on is full sun. The only downside is that our space is fairly limited. There is around 3.75 feet (starting from the neighbor’s driveway) and is around 12 feet in length. We were thinking that the raised bed would be no more than 2.5 feet by 10 feet. Attached is a picture so you have a better idea. We also plan on pulling up the stones. Our house is older (circa 1920’s) and our foundation is stone. Considering it’s such a small amount of space, I’m not anticipating huge amounts of excess water. With all of that said, I have some questions: 1. Is a raised bed doable? 2. Would this impact the foundation? Bess Continues »

What to do about a crab apple tree with the roots chopped?

3 weeks, 1 day ago Q&A

We have a 25 year-old weeping flowering crab apple tree planted in front of our house where foundation repair occurred over the winter. There was a trench dug between the house and the base of the tree. The tree roots that crossed the trench were chopped out. I suspect the tree could now benefit from an extensive watering. Is that thinking correct? If so, is there any point in watering this spring on the side of the tree where the roots were removed? - Mike - Continues »

Dennis says: It’s time to control crabgrass

3 weeks, 2 days ago Tip of the Week

One of the most common problems we face each year in the lawn is fighting weeds. Crabgrass tends to be one of the biggest problems as it takes off under the stress of summer. Crabgrass, although a problem for most people, is one of the easiest weeds to eliminate, given the right product is applied at the correct time. To read more… Continues »
