A rain sensor is mounted somewhere on or near your house (such as a fence or gutter) and can be either hard wired or wireless depending on the type and how much your budget allows. Many use a part called a hygroscopic disc to collect any rain that happens to fall during the day. These discs are designed to expand when water hits them. When they reach a certain size, they flip a switch. The system sends a message that overrides the sprinkler system and causes it to stop watering or not turn on at its normally scheduled time.
You do not need to worry about resetting your sprinkler system after the rain sensor is triggered. They are designed to dry out once the moisture stops and then your regularly scheduled sessions will continue as normal unless rainfall is again detected.
An additional feature found on some of these rain sensors is the ability to stop the system if freezing weather sets in before you have winterized your system for the year. If the pipes are full of water when the weather gets too cold, they can burst. Installing one of these types of sensors can stop this from happening.
If you are interested in adding a rain sensor to your current irrigation system, give us a call. We would be happy to help you choose the right one for your landscape.

When the spring rains start to fall and grass awakens from its dormancy, it is time to take out your garden tools and check them over. Every year you should do a spring lawn mower tune up to make sure that it is working properly and ready to go.
Lawn mowers are a lot like cars when it comes to basic maintenance. Disconnect your spark plug for safety and look at the engine. Notice your spark plugs, oil filters and air filters and change them out to keep your mower running well and make it easier to get it started. If there is corrosion present around the spark plugs, clean it off. Check the wheels, string and other parts to see if there is too much wear and tear.
You may have already done this as part of your preparation for the end of the gardening season, but it’s a good idea to look at the blade now. You don’t want to start mowing and damage your grass because the blades are dull. Remove it from the mower and clean off any rust after securing it firmly in a vice or similar device. Use a file to sharpen the edges and make sure it is balanced once you are done. Otherwise, it could cut oddly or cause other problems.
As part of this general tune up, do an oil change to make sure that your mower has the best chance of starting up and running smoothly. It is also a good idea to use fresh gasoline as it will degrade over time.

Even if the air temperatures are above freezing, the ground can still be frozen for a little while more. Find a spot where you can easily try to dig down and see if the soil has thawed yet. You want to be able to reach at least one foot down.
You properly winterized your sprinklers last fall and shut them down, so they should be ready to go, right? The freezing temperatures in winter can be harsh, possibly dealing damage to your watering lines. There could also have been damage from snow plows or other garden equipment. Sprinkler parts also fall apart over time from normal wear and tear.
Before you turn it on, walk around your yard and physically inspect sprinkler heads, valves and other parts of your system to see if they show signs of problems. Make sure that the water pressure is not too high. According to Rainbird, a sprinklers manufacturer, this range should be within 40-65 PSI (pounds per square inch). We can help you measure this if needed and otherwise check over your system.
As Hunter Industries mentions, you should start turning things back on slowly. If you switch the valves on full blast, the surges can damage the pipes and cause problems. Make sure the timer settings are appropriate for the time of year; you need less water in spring than in summer, so start out lower. Once you have turned everything on, walk around again and see how the various sprinkler heads are doing. Note if there are areas that are especially wet, since this can be a sign of a leak.

Did you know that too much water can drown roots? It seems strange since they are built to take up liquids. However, they also need to have access to air. If there is constantly water present, the roots won’t be able to process the air and die.
Too much water can also cause the roots and other parts to catch fungal disease or rot, since both are more likely to occur in wet situations.
It is also a safety issue since someone could slip and fall when they are walking across your yard.
There are several reasons why water is having a hard time draining into the soil. Investigate around your landscape to see if you can find signs of the following:
There are other problems that would be harder to alleviate, like if the natural level of the groundwater is high or your yard is underneath a slope.

One of the main weeds that you are trying to avoid is crabgrass. You want to apply just before that starts germinating. If you do it earlier than that, it is quite likely that rains and snows will lessen the concentration or even wash it all away. If you wait until too late, you risk the possibility of crabgrass germination starting robustly and the chemical does not have a chance to affect the seeds, wasting the opportunity.
As Cornell University mentions, crabgrass germination is usually most successful when the ground temperatures are in the range of 59F to 65 F. You want to do your weed control just before this happens for the best results.
This kind of herbicide works because it affects seeds during the germination phase. Grass seeds are not immune to this process and they will fail to sprout if you try to grow them when a pre-emergent has been applied. You should have at least a few months time in between reseeding and pre-emergent weed control. Fall is another good time to try patching up your lawn.
You could seed your lawn a few weeks before your herbicide application in the spring. Cornell also mentions that parts of your landscape with little or no plants will warm up sooner since they have one less layer protecting it. Patch up your lawn first and there should be enough time before the crabgrass starts that you can have a successful grass germination rate.
If you try to do only one application, you may still have problems with crabgrass and other weeds. Seeds may be blown or carried into the area and germinate after the herbicide has been washed away. When you do a second application a few weeks later, you can catch these stragglers and keep weeds at bay,
Call us today to get your applications set up. We can help keep those pesky weeds away from your beautiful lawn.

You may have seen tips that a round of dormant oils is useful at this point in the year to help control pests. What are they and why would they be useful?
Dormant oils are usually formulated using petroleum as a base. It is called a dormant oil because of the time when you are supposed to apply it. Some types are now able to be used at other points in the year due to advances in manufacturing. They are used on a wide variety of plants, trees and shrubs.
When you spray it on an insect or mite, it coats their body and keeps them from being able to breathe. Some formulations directly damage certain insects, further leading to their demise.
These oils are typically sprayed on plants to fight pests like aphids, caterpillars, mites and scales. I had to use some horticultural oil when my container peach tree was attacked by red spider mites. I have also used it to try and fight a double dose of aphids and mealybugs on a banana tree houseplant. If I had used a dormant oil on the peach tree at the right time of year, it may not have had that problem.
Some pests can be harder to control than others. Scales can be especially difficult sometimes since some have an armored exoskeleton that is difficult to penetrate. You may need to apply more later in the growing season when the insects and their young larva may be more susceptible.
You are trying to catch any insects that made the plant their home during the winter. Some plants do not do well if dormant oils are used while they are actively growing since the oils can damage their leaves and other parts. When the plant is dormant, there is no foliage present, so it is safer to use.

When you are doing your spring lawn assessment, note whether there are any weeds present in your lawn. In addition to removing these, you may want to use some preemergent weed control before the growing season really gets into full swing.
Lawn chemicals are formulated to be able to affect plants in different ways, so it is important to read the label to make sure that you are buying the right kind. In the case of a preemergent herbicide, it is applied early in the growing season and stops weed seeds from germinating. If there are already weeds present, they will not be effected and will need to be removed using another method.
You also need to make sure that you sow any new grass seeds before you put down this type of chemical. It will be able to affect any seeds that are present and your hard work would be for nothing. Make sure that you do your lawn reseeding and preemergent applications a few months apart from each other for the best chance of success.
Now is about the right time to start putting down your herbicides. You want to do it once the temperatures have started to rise a bit (mid-50s to 60s or so), but not too much farther past that since seeds present will start to sprout. You can also do some in early fall, which will help keep down the weeds in the following growing season.

Spring cleanup season is now in full swing. Your next task is to do a good lawn assessment so that you can see what might need to be done.
Over time, lawns tend to build up a layer of living and dead parts on the top of the soil that can make it difficult for water and nutrients to reach the roots. Every spring you should check the thickness of your thatch to see if you need to take steps to remove it.
If you do have too much thatch, one way to help remedy the problem is dethatching through raking. This action can remove some of the built up matter and allow your grass to breathe better. You can use a power rake or vertical mower to complete this process. If you do not own either of these, they can usually be rented at your local home improvement stores or you could have us come through and dethatch.
Another tool that you may want to rent or contract out is core aeration. These machines remove small plugs of grass and soil, opening up the thatch and improving the health of your lawn. You should water the ground before doing this as it is difficult to do when the soil is dry.
You may also have noticed that there are dead patches in your lawn that has pink or white fungi on it. These could be caused by a type of fungus called snow mold. As the weather warms up, the grass will repair itself and usually green up nicely. You can help accelerate this process by doing a light raking to help the grass dry out and get rid of the snow mold.
What else do you do as part of your spring lawn assessment?

Spring is only officially about two weeks away at this point – huzzah! Now is the time for a good spring garden cleanup to usher in the growing season.
On a day when the snow has melted, look around and pick up any trash that may have blown in during a storm. You can also rake up any leaves that were left over from last fall. Those would likely be a great addition to your compost heap or, if you have enough, in its own pile to create leaf mulch. There are some plants like black walnuts that bear harmful chemicals in their leaves and other parts, and should not be included.
If you have not put down fresh mulch yet this year, now is a good time. It will help protect your plants throughout the year and freshen up your landscape to boot.
Look over your machines and tools to make sure they did not get rusted or otherwise broken during the winter. Sharpen them as necessary, especially if you did not do happen to winterize your equipment.
You can prune many trees, shrubs and perennials at this time. Go over your trees and shrubs to make sure that there are not parts that are dead, damaged or diseased. There are some like maples where they may bleed too much sap if they are pruned too early, so they should be trimmed later in the season.
If you are running short on time or would just prefer that someone else prep your landscape, give us a call. We would be happy to discuss a plan to get your garden into tip top shape for the coming growing season!
What do you do as part of your spring garden cleanup?

Spring is finally just around the corner! I went to my parents’ house today and saw a few variegated bearded iris blades peeping through the soil. It won’t be too long before they fully emerge and proudly display their gorgeous purple blooms.
This is one time of year where it can be a little nerve-wracking in your garden. Some of your bulbs, trees, shrubs and other plants may start putting out leaves and even flowers, but the threat of frosts is not over. If the temperatures fall too much, the plant could be damaged.
Thankfully, many of the spring-flowering bulbs are naturally adapted to lower temperatures. Think about how you sometimes see the earliest-blooming flowers like crocuses peeping up through a blanket of snow. As long as it isn’t prolonged or especially severe, they will usually be fine overall, especially if you mulched as part of your final fall cleanup.
You might have a little more to worry about if they have already put forth their buds or blossoms, since these are more easily damaged. You could add some mulch as part of your spring garden prep. In a pinch, you could make a shelter out of household items like milk jugs (cut off the bottom) or sheets. For the latter, only use them when it’s currently cold and remove during the day if it warms up past the 40s (Fahrenheit). Nurseries and garden centers also sell protective devices like row covers.
I hope that your spring flowers emerge soon if they haven’t yet. They seem so hopeful after a long dreary winter, don’t they?
What kinds of bulbs did you plant? Are they up yet?
