Our weather continues to put a lot of disease pressure on our flowering crabapples and apple trees due to the cool and wet conditions. The disease that is easily seen right now is Cedar Apple Rust (CAR). CAR is a two-host rust, and right now, it can be seen on the cedars and junipers as a strange...

What do bees, ants and termites have in common? At some point in the year, they all swarm. Our honeybee may be the most obvious example as the queen gathers up thousands of support bees from the existing hive and heads off to find another location to set up shop. Those swarms can be seen hanging...

Collecting, storing and using rainwater is a great way to maintain beds and landscape during those times when Mother Nature is not giving us enough water. A rainfall of one inch per hour on a 1,000 square foot surface will yield 10 gallons of water per minute, so it is possible to fill that barrel...

If plants could think, they probably are wondering, "What is going on? Why am I trying to grow in such difficult and changing weather conditions?" I am sure migratory birds and other wildlife are wondering the same thing. There are groups and organizations that monitor just about everything these...

Landscape care strategies have certainly changed since it has gotten dry and hot, and now we have gotten scattered rain events giving water to some and not others. We are seeing the end of the spring bulbs with foliage yellowing and drying down, which is accelerated by the hot dry conditions. The...

Although most Master Gardener help desks are on hiatus right now for the winter, questions still come into the office. It is interesting to see the seasonality of the questions this time of year, and this month, there is a thread among most of them – houseplants. Q: I love my...

This week's column is all about some unwanted indoor insects, but not your usual Box Elder bugs and spiders that made their way indoors this past fall. Homemakers are in full swing baking our favorite cookies and other holiday treats. With that baking comes the potential for all those pesky pantry...

Pesticides are used every day, but many people are not aware of their properties and that they may even be using them. A pesticide is any chemical (synthetic or natural) that is used to repel, control or kill a pest; this might be weeds, pathogens that cause plant diseases, insects or rodents. The...

Back in December, this column talked about doing our best to prevent an outbreak of any one of several kinds of pantry pests in the home. Some of what was shared included sealing bulk amounts of dry pet foods, including the birdseed used all winter for outdoor feathered friends, and limiting,...

Weather Injury on our Plants All of Illinois has seen and experienced some very different, and not so typical, weather the last two months, and we are still waiting to see what is next. March and April seemed like weather from late spring and, on a few days, even early summer....

Birdseed and firewood are two common topics that come up this time of year. Both take some planning to be successful. Feeding the birds means starting earlier than later. Birds need to know early on that there will be something to eat on a regular basis if you want them to hang around in your yard...

Calls to the Master Gardener Help Desks about using bark mulches in the home landscape and gardens has prompted a Q&A column this week. Organic mulches are used on new plants to help them establish and lessen transplant shock. Mulches conserve soil moisture; keep weeds and grass from...

Now that nearly every shade tree and ornamental are in full leaf, gardeners have been spotting some "spots" out there. Those spots can range in color from light green on a very green leaf (oak leaf blister) to black dots coming together to give a much larger blotch of black (tar leaf spot on maples...

Boy, there has certainly been a lot of news coverage this past week or two about our higher than usual and even record-setting temperatures. Just about every arboretum and botanic garden, and even Extension, has been called on for interviews. No one's gardening crystal ball has been very clear,...

This summer, the return of beetles has been evident after an all-time low from the drought in 2012. Beetle numbers have climbed each year since then and this summer have a very strong presence again. Female beetles are attracted to moist soils and locations where there will be plenty of food for...

For those homes having suffered greatly from all the storm water, getting the lawn back can take some time. Grasses have a very limited period to come back once under water, just a few days, and yards in many areas were covered a lot longer. If the water came and went but left the lawn covered...

Colder weather, frozen soil, fallen and windblown leaves, and later any accumulated snow, all will force rabbits to take shelter and begin to look for food anywhere they can. Once the ground is frozen, rabbits will have fewer places to take shelter or hide. Foraging for food will mean staying a lot...

Welcome to another year of gardening! You would think January would be a time for gardeners and homeowners to sit back a bit, yet questions keep rolling in to Master Gardeners and Extension Educators. Let's check out a few of them: Q: With bitter cold weather, is there anything I...

We store our summer bulbs because they are not winter hardy compared to our spring bulbs, which generally are planted in the late summer and fall months so they will bloom for us the following spring. these are also different from those late summer to fall bulbs that also are hardy. Summer bulbs...

Once the fall school term approaches, many home gardeners give up on the vegetable garden as other activities and projects seem to need more attention. Vegetable gardens can provide fresh produce well into October and maybe even early November depending, on what is grown. As the growing season...
