Watering Your Trees and Shrubs in the Fall

Fall leaves

We don’t really think about watering our trees and shrubs (or other plants, for that matter) during the winter since snow is made up of water, after all. However, since the ground is often frozen and it is difficult for water to reach the roots, it is essential that you follow a special watering schedule in the fall so that you will have the best possible outcome for your trees and shrubs.

Beginning of Fall

As fall begins, you should stop watering your trees and shrubs for a few weeks. Rainfall should take care of the plants’ needs naturally. If you were to water at this time, the tree would start sending out new leaves and growth. When the first frosts hit, this would be a recipe for disaster as the tender stems are susceptible to cold damage. Let the deciduous trees finish up their leaf change and food storage. Evergreen trees will not change their leaves, of course, nor will they entirely stop growing during the winter. It is especially important that you make sure they get some watering before frosts.

Late Fall

Once the leaves have changed colors and fallen off, you should start watering again as needed. If it is raining frequently, you do not need to worry about doing this. As is the case with your lawns, you do not want to water frequently and shallowly. Do a deep watering every few days to encourage the roots to dive downward. This will help them find water during the winter and be protected from freezing temperatures.

As soon as the first frosts start occurring, stop watering your trees and shrubs. This is especially important if there is snow on the ground. If you have added enough water, your trees and shrubs will have a better chance of surviving the drought conditions of winter.

Fall Lawn Fertilization

FertilizerBostonLibraryMany people think that spring is the optimal time to fertilize your lawn. It makes sense, right? The plants are just waking up and need a burst of nutrients to get them off to a good start. However, what you really need to focus on is fall lawn fertilization to keep your grass at its best. Choosing this time means that your grass roots will grow and strengthen themselves, improving the overall system. Fertilizing in spring (especially if that is the only time that you do it) is not as good since it encourages blade growth more, resulting in more mowing and potential problems.

The first step you should perform before any fertilization is to do a soil test. You would run into trouble if your soil already happened to have had good (or a bit overabundant) levels of the main nutrients (N-nitrogen, P-Phosphorus, K-Potassium) and you added more unknowingly. This also helps you check the levels of other nutrients and make sure that you get the correct blend. Here in NY, you can contact the Cornell Nutrient Analysis Laboratory or the local Extension Service for testing.

Once you know that you should indeed add a round of fertilization, wait for the right window. If you maintain your lawn frequently, Cornell University advises that you should do a round of fertilization at a rate of one pound for every 1000 square feet in your yard around Labor Day and another in November before Thanksgiving. If your yard is a bit more low key, only the November feeding is necessary.

Know your first freeze dates and watch the weather. If you try to fertilize when it is warm in late fall, a cold snap that is likely around the corner will negate your efforts and even raise the potential of damage from freezing temperatures.

Tune Up Your Sprinkler System for Fall

FallLawnFlickrmikecogh

Your grass may have needed extra water throughout the summer to help it combat heat and drought. As fall approaches, though, it is time to adjust your sprinkler system for the last few months of the growing season.

In autumn, the temperatures start falling. Rainstorms start happening more frequently. With these changes in the weather, it makes sense that you will need to irrigate less. You especially want to make sure that you do not stimulate excessive new growth as it may be damaged from early frosts. You do not want to completely stop watering yet, though. Your plants are busy storing up reserves before they go dormant and need a moderate amount of irrigation.

Consider installing a rain sensor in your sprinkler system as this is designed to override your scheduled sessions should it start to rain. This will save your lawn from being over-watered (keeping it healthier and saving you money) and conserve in the landscape to boot. These days they range from simple electric devices to high tech systems with Wi-Fi capability.

Near the end of autumn, you also want to start winterizing your system so that the pipes will not burst. This is a process where you remove all liquids from the system before the frosts get into full swing. After water is drained out, an air compressor is used to blow out any remaining moisture. Call us to get help in making sure that your system is properly winterized and avoid costly damage.

Lawn Renovations and Enhancements

Laying down sod in a yard

Sod can be used in lawn renovation

Fall is a great time to take a good look at your grass and assess its condition. If wear and tear is minor, you may be able to just overseed. However, if it has taken a beating over the previous months, consider doing some lawn renovations and enhancements. This is a way to improve large sections of your yard without completely starting over.

You start by testing your soil to make sure there are not any underlying problems that would also affect the new seedlings. Dig down a few inches in several locations throughout the lawn and combine it into one sample. Send it off to a soil laboratory (like that available from the cooperative extension service) for analysis. They will tell you if any nutrients are lacking and can give recommendations on what to use.

Next you need rid of the existing lawn in the areas that you want to improve. You need it to be completely bare, so spray it with an herbicide that kills both grass and weeds. You don’t want a kind that will be long lasting, since that would just affect any grass seeds you sow. You also want to make sure that you do not get any on the lawn that you do want to keep.

Assess the condition of the thatch layer. You may likely need to remove some of it, as this is a common cause of problems in your yard. Loosen up the soil and apply any recommended fertilizers and amendments.

Once these steps are taking, you are ready to add the new grass. by the first part of fall lest early winter frosts cause damage. You want to do this Possible choices include seeds, sod and plugs. You can add the same type of grass or add another kind that works well for the planting site conditions. Keep it moist for the first few weeks to help nurture the plants and prevent them from drying out.

Are You Ready to Overseed Your Lawn?

Reseeding a lawn

Newly germinated grass seed in an existing lawn

Over time, bare spots may start appearing in your lawn. These can be due to insects, diseases, summer stress or thick thatch. Once you have successfully treated the underlying problem, you can work on repairing your grass. If the damage is not extensive, an inexpensive way to do this is to sow new seeds over the existing lawn.

The perfect time to do this is coming up, as your new grass plants will do best if planted at the end of August or beginning of September. The worst of summer (heat, drought, weeds) is over and fall rainstorms will help keep your seedlings watered. You do not want to perform this task later than this, though, as you run the risk of frosts harming the new plants.

Mowing

The first step is mowing your lawn. The University of Nebraska Extension Service mentions that it should be about 1.5″ high at this time. This will allow the seeds to be able to hit the ground. It also means that more sunlight and water will reach your seedlings.

Thatch

Next, you need to determine if you have a problem with thatch. If it is not too thick, you can simply run a rake over the lawn to help loosen up the soil a bit. Otherwise, you will need to remove the thatch layer so your new grass will not have problems growing. UNES suggests either using a power rake, a sod cutter or a core aerator.

Seeding

Once the thatch is gone, you can start seeding. Call Cornell University’s Extension Service to see what varieties they are currently recommending for our area. As Healthy Lawns, Clean Water advises, “Overseeding rates should be 4-6 lbs for perennial ryegrass, 6-8 lbs for tall fescue, 2-4 lbs for fine fescue and1-2 lbs for Kentucky bluegrass per 1,000 square feet.” Run a rake over the lawn again to help get the seeds into the top layer of the ground.

Watering

Check often to make sure that the soil does not dry out as the seeds are germinating and while the seedlings are young. Use light syringe cycles as needed, but do not overwater. Following these steps will rejuvenate your lawn and keep your yard looking great.

How Is Your Turf Looking?

Unfortunately there are some weeds throughout this lawn.

Unfortunately there are some weeds           throughout this lawn.

Have the hot summer temperatures taken a toll on your turf? Now is the time to be extra watchful for two problems that can crop up and harm your lawn right when it is naturally stressed.

Brown Grass?

Many lawns are made up of cool season grasses. These will green up before warm season grasses, but can struggle when things start getting hot and dry and may go dormant. You can help prevent this with syringe cycles on the warmest days. Water early in the morning so that the most moisture can travel down to the roots. The grass should perk up again as long as it is getting regular water.

Brown grass can also be a sign of insect problems like grubs. When you are assessing a lawn where some has turned brown, see if other symptoms are present. With grubs, for example, the grass can be peeled back easily since the roots have been cut.

Weeds?

In sports, they say that the best defense is a good offence. The same is true for your lawn; the best way to keep weeds at bay is to make sure that your grass is hearty and healthy. Water it regularly and don’t mow it too short. Plan on adding weed and feed in the fall when they are most vulnerable. This will help set a good stage for the following years. If there are just a few weeds, remove them by hand.

Monitoring these two situations in summer helps you keep your lawn going strong. Call us if you need help getting rid of weeds or brown spots.

Help Your Trees, Shrubs and Other Plants Recover From Summer

Stressed out plants

These plants have begun to wilt.

Summer can be a rough time for your landscape. The combination of heat, longer days and lack of rain can make it hard for your plants to grow and maintain themselves properly. They may start to droop and die. How can you help your plants recover from summer?

The first step is to recognize that your plants are indeed having problems. Signs of summer stress from drought and heat include:

  • Wilting
  • Yellowing
  • Scorched leaves that are brown and dry
  • Leaf loss (defoliation)
  • Slower growth
  • Insects or diseases (stressed trees are less able to fend off these problems)

Do keep in mind that these can also be signs of other problems like nutrient deficiencies, insects, pests and other problems. Scout around your garden to make sure you are not missing any clues.

Try to Prevent Problems Before They Start

One of the best ways to help your plants have the best growth is to choose ones that are well suited to the conditions in your landscape. Native plants originally come from a region and can handle the weather better. Drought tolerant plants in general will adjust to lower water levels.

Watering the Right Way

When you water, ensure that it is actually reaching the plant. Do not water during the hottest parts of the day unless you see plants that are wilting. If you do water them, do so from the base so less is lost to evaporation. Consider installing drip irrigation since emitters are placed right by the plants. As a rule, water for longer periods so the moisture goes down farther into the soil and the roots will follow. It may take some time for plants to recover if they have been stressed for a while.

Should You Fertilize?

You might think it would be a good idea to add some fertilizer to give the plants a boost. This can be detrimental, though. The uptake of the nutrients will stress the system and make it harder for the plant to repair itself as needed. For some plants, you can add some fertilizer in the fall. However, other plants may be harmed if they put out new growth just before a frost.

What Is a Syringe Cycle for Lawns?

SyringeCycleFlickrThatRamenQueen

You usually do not need to water your lawn more than a couple of times a week for proper growth. Sometimes, however, it can be beneficial to do a short syringe cycle in the hottest part of the year, to combat patch disease, and when starting or renovating your lawn.

As a general rule, the ideal time to irrigate your yard is in the early morning hours. If you try to do it in the middle of the night, the water stays on the blades longer and leaves them susceptible to fungal diseases. If you were to water in the middle of the day, the hot sun will evaporate much of the moisture before it really has a chance to reach the roots.

It’s Getting Hot, Hot Hot

When it is really hot and your lawn is showing signs of stress (i.e. turning brown, though you will need to rule out other causes like insects), it can be helpful to do a short irrigation period called a syringe cycle. You do not need to worry about the fact that it is not going to reach the roots as its purpose is to protect the blades from the worst of the heat.

Fighting Against Patch Disease

If you are battling a disease like summer patch, Iowa State University Extension and Outreach advises that performing syringe cycles to reduce stress in your yard can help defeat this problem.

Keeping New Grass Alive

When you first add seeds or sod to your yard, perform extra syringe cycles each day so that they do not dry out. This is essential since the plants have not had a chance to properly put down roots and can die off quickly. Once the roots have become established, you can create a standard watering schedule.

Treating Grubs in the Lawn

White grub in soil

There are several reasons why brown spots start to develop in your yard. One of the most common problems found is the grub. These baby beetles can wreak havoc if there are many of them, so it is important that you start treating the grubs in your lawn once you determine the problem is severe enough.

Grubs are the larval stage of scarab beetles. The adults lay their eggs in the soil. The grubs grow under the surface of your soil and chomp away at the grass roots. If they are present, you will be able to peel away the grass as if it were a carpet. Grubs curled up into a C-shape will be visible. Count how many are present to determine the extent of the problem. As the PennState College of Agricultural Sciences mentions, you should treat for grubs in the lawn if you have 5-10 or more grubs per square foot.

If you are willing to let your grass go dormant for a bit in the middle of summer, this may kill the beetle eggs and stop the infestation. However, many people do not want to have an unattractive brown yard, so treatment is required. Pesticides like imidacloprid are applied in the later months of summer to kill off the larvae. Other treatments like predatory nematodes and milky spore may also be effective in controlling the grub population.

If you think that you may have problems with grubs in your lawn, give us a call. We can assess the situation and rule out any other problems. We can also apply the proper treatments to help banish those pesky grubs.

The Importance of Deep Watering for Lawns

Make sure that you only water as much as needed, when needed.

Make sure that you are watering when needed, not on a daily schedule.

Summer is in full swing now and the weather is getting hot. Your lawn must be getting thirsty and will need to be watered daily, right?

If you did water your lawn a little bit each day, that is actually likely to stress your grass out more over time. Frequent but shallow irrigation prompts the root system to form closer to the surface. If a spell of drought and/or hot weather hits, the soil is likely to dry out and the grass could start to show signs of stress and even die if the problem lasts long enough.

Deep Watering Is Best

Deep watering your lawn as needed will cause the moisture to move down further into the soil. The roots will follow and reach down into the ground where there is not as much evaporation. If the weather is dry, there is now an extensive root system that will allow your grass to have a better chance of finding water and surviving.

You do not want to just crank up your sprinklers and let them go all day, however. Your ground will have a certain infiltration rate (how much it can absorb at a time) based on your type of soil (clay retains water very well and too much will not be taken up, for example), level of thatch present and other factors. Cornell University suggests that you can figure out what the rate is in your yard with the help of a coffee can that has had both ends removed. You would observe how long it takes for 1″ of water to drain, then note the length of time needed to fill it 1″ where the sprinklers hit.

You can use your infiltration rate to determine how long your sprinklers will need to be going. On average, lawns in New York need to replace 1″ of water a week, says Cornell University. If it rains one week, you may not need to do any watering at all.

Give your lawn a better foothold by using deep watering instead of shallow daily irrigation. Give us a call if you need help to figure out your infiltration rate or adjust your sprinklers.
