How Are Your Plants Grown?

Our container grown perennials and shrubs are grown in our climate-controlled greenhouses in Western Michigan. They have been in a cool greenhouse and can withstand some light frost (30-32 degrees F.) We try to keep our plants cool so they can better adjust to their new outdoor environment, especially early in the season.

How Many Plants Should I Order?

For the most part, garden plant spacing comes down to personal taste and what you want in a landscape. The following are some general guidelines for plant spacing.
The first thing is to determine the dimension of your planting area. Keep in mind that closer spacing will allow plants to fill in quickly, discourages weeds, & helps shade the soil, thus reducing evaporation.

CLICK HERE for our Plant Estimator Chart

As a general rule, the average spacing for perennials are 10-12" on center.

Ground Covers
Ground Covers should be spaced 6-12" apart depending on the variety and how quickly you want to fill the area.

Taller Plants, Shrubs
When planting for shrubs and taller perennials, consider their ultimate spread.
Take the overall plant height and divide by half. (Example: 48/2=24). 24 inches is the spacing distance you can use between plants.

We make Buying In Bulk extremely affordable with savings from 5-40% off the single-plant price.

The more plants you buy of a certain variety, the more money you save!

How do I know if a plant is hardy in my area?

The United States Department of Agriculture (USDA) has devised a system to provide gardeners with a basic guide to plant hardiness. The Hardiness Zone Map system divides the United States and Canada into numbered zones based on lowest average winter temperature. Even within a zone, different micro-climates exist, such as large urban areas which may be warmer or land situated at different elevations.

Click Here to find your Hardiness Zone 

 Return to top of page

What Effects Plant Hardiness?

The Hardiness Zone Map is a valuable tool but it is not foolproof. There are a variety of factors that can influence the hardiness of a given plant in a garden. These factors include: soil type, drainage, snow cover, exposure to wind, winter, rainfall (or lack of), as well as fluctuations in temperature.

Do I need to prepare my soil?

We just can't help but re-emphasizing the importance of soil preparation. If you think of plants as your children, they need nutrients and room to grow. Click here for our article on Soil and Moisture Basics.

How often should I water?

A general rule of thumb is to water about 1 inch a week. It is critical that the first year with newly planted material you don't skimp on watering. Mature, second year plants have roots that run deep into the soil, so their watering needs may be a lot less.When we mention that a plant is drought tolerant, we refer to an established second year plant. If your plants begin to wilt, it is time to water.

Will my plants flower the first year?

As a general rule, you will enjoy flowers the first year with plants from Great Garden Plants provided they are planted early enough in the spring season to become established.
