Are There Aphids in Your Landscape?

AphidsViaMoi

If you have ever seen clusters of pear-shaped insects on the stems of your plants, you may have an infestation of aphids. I see them on rose bushes, especially, but they may be found throughout the different areas of your landscape. They come in colors like green, pink and black.

What Problems Do Aphids Cause?

Aphids are very fond of cutting into stems and sucking out the juice from plants. This can stunt the growth of the plant. The aphids also may pick up bacteria, viruses or fungi and transfer them to other plants, spreading disease.

In the case of grass, this action can cause your grass blades to turn yellow and orange before dying. Other plants may show problems like yellowing, curling and wilting of leaves and possibly death.

They also can be problematic because of a sticky substance they expel, called honeydew. It can get onto surfaces and cause damage. When it is left on plants, the wet sugary conditions can encourage a fungal problem called sooty mold. While it is overall not too harmful in many situations, it will cause discoloration of your plants.

Why Are Aphids Difficult to Destroy Completely?

These insects can reproduce very rapidly, producing a new generation at intervals of approximately two weeks. They do not even need males to reproduce since they employ a process called parthenogenesis. In fact, aphids are born pregnant! As you can imagine, it can be hard to keep up with the pest population since even one surviving aphid can repopulate an area.

What Are Some Ways to Get Rid of Aphids?

On your smaller plants and shrubs, you can try spraying them with water to knock them off. You want to do this early in the day so that the leaves have time to dry out and avoid diseases. Insecticidal soaps may also be beneficial, as well as encouraging insects like ladybugs that feed on aphids.  If the problem is severe, lawn care companies can spray with pesticides, though this will also kill off the good insects.

You may have noticed that there are ants living near the aphids. They are protective of the aphids since they like to harvest the sweet honeydew. Controlling ants will make the aphids more vulnerable as you take measures to get rid of them.

How to Keep Your Plants Healthy This Summer

Keep your plants healthy this summer with appropriate care.

Are you wondering how to keep your plants healthy during the warmest time of the year? Plants can naturally become stressed during summer, so you will need to watch over them carefully. Here are three ways to make sure your garden is in tip-top shape.

Scout Around for Insects, Pests and Other Problems

You definitely want to stay on top of problems so that you can treat them before they become too serious whenever possible. Some signs you may notice, among others, include:

  • Wilting
  • Rotting
  • Cankers
  • Spots on leaves
  • Leaves that turn yellow or brown
  • Holes in leaves, branches or trunk
  • Webbing
  • Galls
  • This one seems obvious, but insects themselves are seen

Once you notice a problem, you can do research to see what is causing it and how it can be treated. There may be several different methods including mechanical, cultural, biological and chemical controls.

Keep Your Watering on a Consistent Schedule

As I have mentioned before, it is usually better to water your plants just a few times a week, making sure that it is for a long enough period that they can get the amount that they need. If you do notice a plant that seems extra wilted, go ahead and give it a drink. However, do make sure that it needs water as overwatering can, strangely enough, cause wilting also.

Consider Moving Potted Plants to Shade

Container plants can have problems sometimes since their soil area is smaller than plants in bedding areas. The roots do not have the chance to fully spread out and can struggle when the soil dries out.

One way to help slow down this problem is to move the pots to an area that is a bit cooler. This can be under an umbrella or close to your house. You could also consider bringing them indoors as needed if it is really hot.

There are some factors to think about when deciding to move potted plants. Make sure that the specific plant is able to handle partial shade, since many need full sun. Your nursery should know if it can or you can search on the Internet by using the plant’s name.

If you bring them inside, you would need to harden them off when you do set them back outside. The environments are quite different between your house and your garden (with the latter usually being harsher,) so the plant can go into shock if it is just set outside. When you harden off, you take them out for a short period on the first day and gradually lengthen it over the course of about a week.

Are There Foxtail Weeds in Your Grass?

Foxtail weeds can appear in your lawn

If you have noticed that some areas of your lawn look a bit different and there are spikes of seedheads shooting up, you may have foxtail weeds in your grass.

There are three different species that you commonly see throughout the United States. They are:

  • Giant Foxtail (Setaria faberi)
  • Green Foxtail (Setaria viridis)
  • Yellow Foxtail (Setaria glauca)

 Why Are Foxtails a Problem?

They form in clumps and tend to remain upright, breaking up the uniform appearance of your lawn. They send up seedheads that are full of seeds, producing new plants. These seeds are also able to cling to animals and clothing, causing potential pain and problems.

These species can act as a host for nematodes, which can then affect your lawn. Foxtails also produce chemicals that can actively harm other plants in the area to reduce competition through a process called allelopathy.

Controlling Foxtail Weeds

One way to help control these species is to apply preemergent herbicides. Since these plants reproduce by seeds, stopping them before they can really get growing is helpful. However, if seeds were dropped in that location before or are blown in, they can germinate after the herbicide has worn off. Applying more than once a summer can be helpful in this case to control foxtails and other weeds with similar tendencies.

As with all weeds, keeping your lawn grass in a healthy state helps keep undesired plants from taking over. Properly growing grass forms a good root structure that can grab the nutrients it needs and the plants can shade out seedlings.

Can You Overwater a Lawn in Summer?

Overwatering A Lawn is Possible

As the weather heats up, you might think that your lawn needs as much water as possible to survive the summer and grow properly. Can you overwater a lawn in summer?

Water Longer and Less Often

It may seem counterproductive, but you only need to water once or perhaps twice a week in many situations. If you try to set your sprinklers so that they water a little daily, the roots get lazy and stay near the surface so that they can grab the water there. If the weather is especially hot and you do not water, the grass is now prone to scorch and other problems.

When you water longer and less often, it trains the roots to go deeper into the ground. In times of drought, there is a greater chance of your grass being able to find some moisture since the roots are longer and more widespread.

Plants Can Drown Too

If your lawn is continually wet, your grass might drown. Plants actually do take up oxygen from the soil as part of their respiration. If the roots sit in water for a long time, they cannot get the oxygen that they need and can end up effectively drowning.

Too much water surrounding the roots for an extended time can also lead to problems like root rots and other fungal diseases. Fungi are especially drawn to moist areas and thrive there.

How Much SHOULD You Water, Then?

Cornell University here in New York suggests that all you need on average is an inch of water per week. You can experiment with your sprinklers to see how long you need to water to achieve that goal using a device like a rain gauge or simply collecting water in a can. You also need to examine how your soil absorbs the water to make sure it’s not being applied too fast.

It’s Time to Prune Spring Flowering Shrubs and Trees

 

Prune forsythia after blooming

Forsythia should be pruned after it is done blooming in the spring

You may have heard that you should do much of your pruning in the spring while your trees and shrubs are still dormant. However, this could destroy the floral display of some species. Why would this happen and which species are affected?

Last Year vs. This Year: Wood and Buds

Trees and shrubs vary on when they produce their flower buds and generally fall into two groups: the “planners” and the “procrastinators”. We are prone to imagine that they fall on the procrastination side and produce flower buds every spring as new wood emerges. These are safe to prune in late winter or early spring before the plant blossoms since you won’t be disturbing the blooms.

However, some trees and shrubs do fall more into the “planner” category. They are efficient and start forming their flower buds in the fall before the next growing season since they tend to put forth their flowers so early in the year. If you were to prune them while they are dormant, you definitely run the risk of stripping away a lot of the flower buds and destroying your blossom display. Instead, you would prune spring flowering shrubs and trees once they are done blooming.

Which Trees and Shrubs?

This is by no means a comprehensive list, but here are some of the most common trees and shrubs that should be pruned after they are done blooming. It is a good idea to ask a professional about the specific trees and shrubs in your yard to be sure.

  • Azalea and rhododendron
  • Beautybush
  • Deutzia
  • Flowering crabapples
  • Forsythia
  • Hawthorn
  • Honeysuckle
  • Kerria
  • Lilac
  • Quince
  • Viburnum
  • Weigela

Do you have any of these trees and shrubs in your garden?

Fertilize Your Lawn at the End of May

 May is a good time to fertilize your lawn

Growing season is into full swing these days. Plants everywhere are blooming and your lawn has woken up and started growing again. Now that it’s had a bit of a chance to come out of its winter slumber, you should fertilize your lawns around the end of May.

Why Should You Fertilize?

Plants are like people in that they need proper nourishment to grow. Plants are designed to pull water and nutrients from the soil. However, some areas may have become depleted over the years or had low levels from the start. Adding fertilizer is like a human taking a vitamin to ensure that they are getting everything that is needed to stay healthy.

What Kind of Fertilizer?

It is always a good idea to get a soil test every new growing season so that you can make sure that you are adding the proper nutrients. The laboratory will tell you what is in short supply. The three main nutrients that are on a fertilizer package are nitrogen, phosphorus and potassium. The three numbers on front (written like 5-5-5) let you know the percentage of each nutrient that is included, in that order. Grass is always hungry for nitrogen, so your best choice of lawn fertilizer will include that.

How Much Do I Need?

The amount will vary depending on the product that you are using and the results if you had a soil test performed. You will need to have the square footage of your lawn handy as this will be involved in figuring out the amount to apply. The label will tell you how much to add for every 1000 square feet or similar measurement.

Do a Spring Lawn Mower Tune Up Now

Do a spring lawn mower tune up every year

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.

Check Over and Replace Parts as Needed

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.

Clean and Sharpen Your Blades

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.

Add Fresh Oil and Gas

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.

Get Your Irrigation System Ready for the Growing Season

Tune up your sprinkler system this springSpring is here in all its glory. Plants are coming alive again and the temperatures are creeping up. There are still days here and there that are colder, but it’s definitely on the upswing. For much of spring, rain is enough to take care of all of your landscape’s watering needs. However, you should work on getting your landscape ready now for the rest of the growing season.

Can You Turn It On Yet?

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.

Get Your Irrigation System Back Up to Speed

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.

Turn It On Carefully

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.

Apply Your Pre-Emergent Weed Control Now

PreEmergentWeedControlFlickranneh632One of the best ways to control weeds, of course, is to never let them get started. A good dose of pre-emergent weed control will keep seeds from germinating and dominating your lawn.

When Should You Apply It?

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.

What About My Grass Seeds? Will They Be Affected?

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.

Why Do a Split Application of Pre-Emergent Weed Control?

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,

It’s Spring Lawn Assessment Time!

Spring Lawn Assessment Including Raking

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.

Dethatching and Aeration

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.

Raking Out Fungus

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?
