What happens if I'm not satisfied?

Please call or email us, 855-797-5268, or We'll ask you to send photos of your plant so we may evaluate what happened, but we do not need you to send a plant back to us. Once we get the photos we'll be able to process a replacement or refund immediately.

What is the guarantee that I will receive healthy plants?

We take great pride in our plants and make sure they are healthy and vigorous when they leave our greenhouse. We guarantee our plants and will send replacements if needed. Please have your order number and a photo of your plant ready, then let us know via email at so we can work to resolve your issue as soon as possible.

What is the difference between the container sizes?

The difference in plant maturity between each of the sizes is approximately: 4.5 in. Quart = 6 months old, 1 Gallon = 1-year-old+, 3 Gallon = 1.5/2 years old.

Plant Care

Is this plant hardy/will it survive here?

Hardiness depends on the location you are in and the plant itself. Find out what USDA hardiness zone you are in at and check the plant tag and/or the product page to find out which zones are right for the plant.

What is the light requirement for my plant?

You can locate the light requirement for your plant on your plant’s tag or on its product page. Full sun is 6-8+hours of direct sunlight, Part Sun/Shade is 4-6 direct hours of sunlight, and Full Shade is 4 hours or less of direct sunlight.

When is the best time to plant?

Generally, the best time to plant perennials and shrubs is in the spring or fall. Cool temperatures, reliable rainfall, and short, bright days help plants make a quick and easy transition to your landscape. Depending on when you plant, make sure the threat of frost is gone before planting in spring and you provide at least 6 weeks before your ground freezes in fall. If you are unsure, mid-November is a safe planting deadline for nearly everyone in the U.S.

How and when do I cut plants back?

This completely depends on the plant itself. Please see the product page for specific maintenance information.

How do I protect my shrubs for the winter?

As long as the plant is planted in the ground 6 weeks before the first frost no additional protection is required. However, we do recommend applying a 2-3” layer of mulch around the plant as it acts as a blanket for the roots.

Can I leave my potted plants outside for winter/ how to overwinter containers?

If the plant is rated two zones lower than your current hardiness zone it is safe to stay in the pot outside all winter (example: plant hardiness zones are 3-7 and you live in zone 5 or above). If not, we recommend storing the container somewhere cold that does not go below freezing, like a garage, shed, etc, and wrapping the container in burlap or other material to further protect the roots. Plants that lose their leaves in the winter do not need sunlight during dormancy but evergreen plants do and would need to be placed near a window.

How do I change the color of my hydrangeas?

With the exception of some hydrangeas, such as the white varieties, most hydrangea bloom color depends on the pH of your soil. The more acidic your soil, the bluer the bloom. The more alkaline in the soil, the pinker they become. Too encourage pink, add lime. The pink will not appear right away but over time. Add aluminum sulfate to the soil to encourage blue flowers.


Can I grow a shrub in a container?

Yes. However, unless, you have a very large container or a dwarf plant it will eventually need to be transplanted from its container and into the ground. The growth rate and current maturity of the plant will determine when transplanting is necessary.

How close can you plant plants to each other?

Ultimately, this is based on your preference. Most plants will grow in close proximity to one another. Planting them close together prohibits the plant from expressing their true botanical form. This may be preferred if you are attempting to form a screen or hedge.

If the preference is not to have the plants touch each other when they reach maturity, first determine the mature spread of the plant in question. The mature spread of each plant is displayed on each plant product page and plant tag.

How deep do the roots grow?

Generally, a plant’s roots will be about the same size as the plant is on top of the soil. Deep rooting depends on the species, the soil, and the availability of moisture. Very heavy and hard clay discourages deep root growth. Sandy or loamy soil allows for deeper root penetration. The farther away the roots are from the plant, the smaller the roots are in circumference.

General Concerns

Do you use Neonicotinoids or pesticides on your plants?

No, we do not use Neonicotinoids. We mainly use biocontrols to combat pests on our plants. We do use pesticides occasionally to ensure you receive a healthy plant with no harmful bugs. The pesticides we do use are Neonicotinoid free and will not cause harm to any pollinators or humans that touch it. We time the usage of pesticides to ensure that it is not in your plant’s system when it is shipped. We only use pesticides that have less than a 24-hour active period. All chemicals dissipate long before it is put in a box and shipped to you.

Is this plant invasive/does it reseed?

No, our plants are noninvasive. Some are seedless and others have seeds that are not viable. Proven Winners has bred the invasiveness out of the plants so that it has only the good qualities and none of the bad.

What is the pH of the Premium All Purpose Potting soil?

Our soil is designed to be neutral, between a pH level of 6.5-7. It is made from a blend of Premium Canadian sphagnum peat moss, processed softwood bark, and horticultural-grade perlite. It contains a professional wetting agent and dolomite lime to buffer soil pH.

Will deer eat my plants?

Some of our plants are deer resistant; some plants are not. However, even “deer-resistant” does not mean it’s “deer-proof.” Deer will eat just about anything if they are hungry enough. You may want to try using a deer repellent such as PlantSkydd around the perimeter of your yard to keep deer away from your plants. Please see the product page to find out if your plant is deer resistant.

How fast/quickly does this plant grow?

It is difficult to categorize the growth habits of the many plants that we sell. A slow-growing shrub would be a plant that grows less than a foot a year. A fast-growing shrub may grow in excess of 2.5 feet a year. Growth rates of the various plant classifications are estimated based on the plant being placed in ideal conditions with good fertility, adequate moisture and planted properly.
