Oak trees are proving to be more important to ecological balance than previously thought. Of the 60-plus native oaks in the United States, 22 of them are right here in Illinois. Homeowners know them for their majestic size and shape, and this time of year, for their colors of red, yellow and gold...

Raspberries are a wonderful addition a backyard, providing us with berries for fresh use while they are in season and for preserving to enjoy later. Raspberries are a perennial, giving us many years of production, though there should be some annual pruning done. This will prevent that row we...

Here we are, nearing the end of May. Maybe the beds in the backyard look OK, or maybe not? We love our lawns, yet grass can move into our landscape beds in a stealth-like manner while we are waiting for better weather for weeding and edging. Putting a strong clean line on the landscape beds really...

It happens every year, almost like clockwork. (I say "almost" because not every tree leaf disease shows up every year.) Another good point to make right way is common leaf diseases are rarely fatal to a tree. Some of our common tree leaf diseases are: Anthracnose, often seen on sycamores; and...

So many things, only so much space to get them down. I think the weather has been both good and bad, depending on your perspective right now. Lawns usually begin to slow down a bit, as the natural spring flush begins to pass, but as long as the rains continue, grass will continue to grow at an...

Raise your hand if you are cooking for the holidays? My guess is there are quite a few of you. Ever think about all the fresh vegetable waste that goes in the disposal or garbage can? Cooks can get busy and not think about the compost pile or bin sitting just outside. If the pile or bin is large,...

Late summer and fall are great times to plant ornamental and shade trees in the home landscape. The weather is comfortable for us and the trees can begin to establish themselves in yard before the cold weather sets in for the winter. If you are planting a flowering ornamental like a crabapple or...

The fall foliage show is back by popular demand (and because we cannot stop it anyway). Those reds, yellows, and oranges now have begun to subside, and soon enough a night of really below freezing temperatures will bring that to a close. Then, all those leaves will end up in the landscape. Our...

You know it is finally spring, not by the calendar, but by the first landscape maintenance trucks hitting the road without snowplow attachments. Mother Nature is struggling a bit; we are having warmer days, but the nights are still crisp. Those warmer temperatures are needed by many blooming plants...

Time to address several good questions that Master Gardeners have gotten already this early spring. We are right on schedule for some; others will have to wait, being weather dependent. Q: I need to trim my oaks and maples. Do I do it now or wait? A: We have about two weeks (by...

Now that the vegetable gardens have been planted for a few weeks, questions to the Master Gardener help desks have switched over from "How do I?" to "What's going on with my vegetable plants?" Here are a few commonly asked questions: Q: My spinach and lettuces are sending up flower stalks before I...

Bird feeders will bring in a variety of migrating birds during the early spring on their journey to summer digs. This is before there is much for them to eat elsewhere, in nature or in home landscapes. Our winter resident birds that have hung out with us all winter still need that seed too. Be sure...

That magical average frost-free date of May 5 for our area is quickly approaching. Given the weather patterns we have been having, sticking to the May 5 date may not be a bad idea this year. We read about that average frost-free date where there is still a 50/50 chance of a frost and then that "...

Our weather has very likely already messed up any plans for getting those early plants in and seeds sown. No one has a clear crystal ball right for when consistent spring weather will happen. If you have sown seeds for later planting as transplants, keep them from getting any taller until they can...

Many weeks have gone by since containers and hanging pots were planted. At the beginning, watering was easy; plants were small with a limited root system so the container or pot held lots of available water for good growth. Fast-forward to now, and the water management has changed as the plants...

Many of our fall yard and garden efforts have been delayed by weather. So what should we be getting done? One of the ongoing efforts has been to keep the lawn mowed, and, if we haven't already, now we need to contend with the leaves that came down in great numbers. There is very likely more than...

An unofficial windshield survey shows an alarming level wilting foliage on ornamental and shade trees planted in the last two to three years, along with trees planted this spring. It takes an extended dry period to have tree foliage wilting. It is obvious when flowers, vegetables and our lawns need...

You would not think of intentionally planting poisonous plants in the home landscape, but that is exactly what the University of Illinois - College of Veterinary Medicine has done on campus, and for good reason. They have created an actual garden to grow...

Mosquitos are adjusting to our ever-changing weather patterns just like our plants in the home landscape this season. May into June would be our traditional time mosquitos start show up for the summer. This season, April had the rain and not May, so mosquitos can be behind a bit. Mosquitoes favor...
