FAQ

Answers to Your Queries

When should I prune my shrubs?

Generally speaking, spring-flowering shrubs, such as lilac and forsythia, bloom in spring on the growth of the previous season; sometimes referred to as old wood. The best time to prune spring-flowering shrubs is after they have flowered. This allows them the summer time to establish growth needed for blooms in the spring.

Summer-flowering shrubs, such as potentilla and spirea, bloom in summer on the current year’s growth; referred to as new wood. Prune summer-flowering shrubs in late fall after a good frost or very early in spring. These shrubs will bloom in summer on the current year’s growth.

Prune evergreen shrubs, such as juniper and yew, in early to mid-April before new growth begins. Light pruning may also be done in midsummer.

When is the best time to prune shade trees?

February through March is generally regarded as the best time to prune most deciduous trees. The absence of foliage at this time of year gives the individual a clear view of the tree and allows the selection and removal of appropriate branches.

Also, the walling-off or compartmentalization of wounds occurs most rapidly just prior to the onset of growth in spring. Oaks are an exception. The winter months – December, January and February – are the best time to prune oak trees.

Deciduous trees can be pruned at other times of the year with little or no negative consequences. However, if possible, avoid pruning deciduous trees in spring when trees are leafing out and in fall when trees are dropping their leaves.

When is a good time to plant containerized trees?

Spring or fall works equally well for containerized tree planting.

Fall is a great time to plant containerized or balled and burlap (B & B) deciduous tree(s). Putting trees in the ground in the fall gives them time to recover from transplant shock and establish a healthy root system before dormancy. 

Ideally, any tree planted in the ground should go in around Labor Day with frequent and consistent watering through mid-October. By spring they will be comfortable in their new home and weather conditions will promote leaf and root formation in preparation for summers' stresses.

When is a good time to plant conifers?

Containerized conifer trees have a limited root system. Their roots have been going around in a circle for a major portion of their lives. 

Conifers that are purchased and planted in the fall, especially late fall, do not have enough time to grow their roots in the surrounding soil and become established. This can leave them extremely vulnerable to high winds, heavy snow loads and winter injury. 

Many can enter winter dormancy in a water-stressed state and suffer additional needle injury. Conifers will continue to lose moisture from their needles all winter long even though the tree is dormant. 

If the soil is frozen there is no water uptake from the roots and if the air temperature becomes 40 degrees on a bright sunny day, a conifer tree's needles will be losing moisture with no way to replace it, resulting in "Winter Burn." 

This holds true for leaf trees as well - except there are no leaves on the trees so that the impact is less. When planting conifers in the fall, make sure to plant early and water regularly and thoroughly up to the time frost is in the ground.

When should I trim my Knockout Roses?

In their first two to three seasons, shrub roses can be left unpruned. This ensures the pruning of a mature plant. 

Young plants need trimming only to remove dead or dying parts. A mature knockout rose should be about 4' high and 4' wide. You can sometimes go a year or two between trimmings to allow the plant time to reshape. 

In the late winter or early spring, just as the buds are forming and no new growth has occurred, remove one-third (rule of thirds) of the canes. You can cut healthy shoots back by one-third to one-half of their existing length without damaging the plant. 

If you cut the canes back further than that, however, you might stunt the growth of the bush, which will then spend more time producing foliage to replace lost growth rather than putting its energy into flowering. 

Be aware of crossing canes and remove one so that they do not rub and open wounds that allow any disease to enter. Remove dead canes, especially those towards the center. This allows better air circulation and reduces disease possibilities.



When do I do major cutbacks on my bushes and shrubs?
You can do these once the bushes and shrubs go dormant which depends on the weather during any given year. They usually go dormant between the months of October and January.

When can I trim Spring flowering shrubs and still have flowers that will bloom the following season? Ex- Lilacs, rhododendron, azalea, etc?
They can be trimmed immediately after they bloom and you will still get flowers the following year. You usually have 3 to 4 weeks before the plants start to form the buds for the following year.

When should I trim evergreens and broadleaf evergreens such as boxwoods and yews?
You can trim them in early Spring after freezing temps have passed but before new growth starts to appear. This is usually March through April. You can also trim them in late Summer through mid-Autumn after they are done growing for the year which is usually July through September. 

When do I cutback my perennial plants excluding coralbells, geraniums, grasses, creeping phlox, thyme, or groundcovers?
A: You can do this in early Spring usually March-April or in late Autumn once the perennials are dormant for the year. You can also do it anytime throughout the Winter time if you’d like as well. 

When do I cutback ornamental grasses?
You can do this early Spring, March through April.

When is the best time to plant Trees, shrubs, perennials, etc?
Spring is a great time to plant, usually March-May. Try and avoid the hot months of summer. Another good time to plant is in the Autumn, usually September-November. If neither of these times are available for you to plant, then you can also do it once the shrubs go dormant during the winter months. 

When is the best time to fertilize trees, shrubs, and perennials?
Immediately when planting the new specimen. If it is an existing specimen then early Spring, usually March-May, is the best time to fertilize because this is right before everything starts to need and use a lot of energy to grow for the year. Always avoid the hot months of summer or just use a very weak fertilizer during this time. Autumn is not the best time either because shrubs are beginning to go dormant. If you do fertilize in the fall use a dormant fertilizer or a slow release fertilizer, this will suffice.

How do I fertilize my trees, shrubs, and perennials?
If it’s a new planting use soil amendments including Wagner’s soil mix. Pair this with a slow release fertilizer tab or a nutri pak. If it’s an existing specimen, then use the appropriate amount of fertilizer stakes that you pound into the ground for a direct specific application. If you want to go indirect then you may use a granular fertilizer such as milorganite that you just spread all around the area on top of the ground.

How often should I water newly planted trees, shrubs, and perennials?
You have to be proactive when considering when and how often you should be watering. Every variety of tree, shrub, and perennial requires a different amount of water as well as how often they need it. Best rule of thumb is to always keep your eye on the specimen and if it is wilting or looks droopy then it is telling you it needs water. Soak it in very well if it gets to that point. After soaking let the specimen dry out and then soak again, repeat until its root system is fully established. Arborvitaes require a large amount of water and they will not tell you when they need a drink by looking at the foliage. By the time an arborvitaes foliage shows stress it is usually too late.
  
What is the best way to water trees, shrubs, and perennials? 
The goal is to acquire a deep root soaking for the plant and very minimal water run-off and waste. To do this use a garden hose or watering can with a very slow trickle of water coming out. Tree watering bags, made specifically for trees, take all the guesswork out of the equation. You can also use a bucket that is filled with water. Drill a small hole or two in the bottom of the bucket and set next to the specimen that is to be watered. Natural gravity will do the rest of the work for you. Just refill the bucket when necessary.
 
How often should I water established or mature trees, shrubs, and perennials?
Only water if the specimen is wilting or we go 2 weeks without water in the midst of drought conditions.

How do I prepare trees and shrubs for winter, newly planted or mature?
You need to deep root water the specimens before freezing temperatures become regular. Another thing to do is to spray evergreens and broadleaf evergreens with “Wilt Proof”. Apply this to the foliage, it will hold in moisture over the winter months’ n help prevent winter burn.

When is the proper time to trim shade and ornamental trees?
Winter or mid-summer is the recommended time frame, preferably in the winter. Doing it in the winter will cause the least amount of stress to the tree.

When is the best time to trim fruit trees and small fruit?
Winter is the best time but you can also do it in early Spring before everything starts to bud out. 

What is the best time of day to fertilize your lawn?
Late afternoon is the best time to do this.

How much does it cost for a landscape design?
It depends on a variety of factors such as the size of the project and how many labor hours it will take to come up with the design. As well as the specifics of each individual design and what the client all wants out of it such as all the details. Pricing is figured on an individual basis so just call us to set up an apt!

Is there a warranty on your tree and plant stock that you sell?
Yes, there is a 1 year guarantee on everything we sell with no questions asked as long as we installed the job or if the client purchased the proper material to install it with. Ex- Wagner’s soil mix, compost, peat moss, fertilizer tabs or packets, nutri-paks, mycorrhizae, or planta gel. If none of these things were purchased to install with the specimen, then some questions may be asked before replacing the specimen for free.

Where do your trees, shrubs, and perennials originally come from that you sell at Wagner Nursery Inc.?
Everything comes from northern growing nurseries where the trees, shrubs, and perennials are specialized for our growing zone and climate.

What is the best time of the day to water?
The best time of the day to water is in the early morning or late in the afternoon.

How do I protect my investment (new tree) in general or from a rabbit or deer?
You can purchase a mesh tree guard or a roll of tree wrap from us for the trunk. You can purchase mulch from us for around the base of the tree to hold in moisture and to keep the mower and weed whacker away from the trunk to avoid scarring and damages. You can purchase liquid fencing from us to keep unwanted animals from eating it. If you have bad wind issues you can purchase a tree staking kit from us. 

How do I insure my new or existing tree, shrub, or perennial is going to do its best, as far as growing and health goes?
Use at least one of the following items, preferably a combination of some of these items as well as proper watering- Wagner’s soil mix, compost, fertilizer stakes, peat moss, fertilizer tabs or packets, nutri-paks, mycorrhizae, or planta gel. 

Do you transplant trees?
We can give you an estimate to transplant a tree or trees as long as the trunk of the tree is no larger than 3.5 inches wide measured 6” from top of root ball.

After purchasing sod from Wagner Nursery Inc. how long do I have to wait before I can mow it?
Usually you must wait about 2 weeks. The best way to tell is to pull up on the sod and see if it is rooted in yet or not. You want to mow after it has rooted in.

Should I fertilize the new sod I have just purchased?
Yes, you should fertilize the new sod. Make sure to apply the fertilizer onto the ground before you install the new sod. Any starter fertilizer is suitable, we carry triple 13 or 12-25-13 or anything with a large middle # in the sequence. The middle # is phosphorus which helps root growth. 

What do I do about the brown spots in my yard?
Remove the dead or dying grass and replace it with fresh grown sod from Wagner Nursery Inc. You can also regularly fertilize and it will eventually fade with new grass creeping in and taking over its spot.

How do I plant a potted tree, shrub, or perennial? 
Remove the pot from the root ball, break apart and bust up the root ball so roots are not going around in a circular motion, dig a hole twice as wide as the root ball, make sure the hole is no deeper than the depth of the root ball, and as you start backfilling the root ball with excavated dirt add water to eliminate air pockets until the specimen is firmly planted in the ground. 

How do I control weeds in my existing landscaping beds without having to pull them every few days?
Get on a regular maintenance plan that includes regular pre-emergent applications that will eliminate weed seeds before they germinate. Do this 4 times a year starting in the early spring and then every 2 months after. The pre-emergent will not eliminate weeds 100%. To take care of anything that sneaks through use a weed spray to spot treat and kill small weeds that appear. Stay on top of it because if they get out of control it’s a nightmare trying to regain this control.

When I plant a fruit tree can I plant just one or do I have to plant two of them?
It all depends on the variety and species of the fruit trees you will be planting. Some do need a pollinator and some don’t. As a good rule of thumb always assume they do need another pollinator. This pollinator tree with be of the same type of fruit as the first tree but will need a be a different variety. Ex- If planting a honey crisp apple then plant a pollinator tree that may be a red delicious apple. By doing this it insures that you get bountiful fruit and ample harvests every year because proper pollination has occurred. 

Why is my evergreen tree killing all of the grass around and under it?
This happens mainly because evergreen trees create a lot of acidic byproducts as a result of their natural life cycle. This is shed from the tree in forms of needles and dust etc. Grass typically does not like or thrive in acid environments and that is why it dies. Another reason could also be from the shade that the tree causes. Most grass varieties do not like to be in the shade.
