When to Plant Perennials

Perennials are a great addition to any garden or landscape. Unlike annuals that need to be replanted every year, perennials come back year after year, saving you time and money. One of the most important things to know about planting perennials is when the best time is to do so. In this article, we'll go over some guidelines to help you decide when to plant perennials.

First Year vs. Established Plants

It's important to note that the planting timeline for perennials can vary depending on if you're planting new, first-year plants or established plants that have already been growing in containers or in a different location. For first-year plants, the best time to plant is in the early spring. This is when the ground starts to warm up, and the plant will have time to establish itself before summer heat sets in.

For established plants, the best time to transplant them to a new location is during the fall. This is because the temperatures are cooler, and the plant has a chance to acclimate to its new environment before the winter cold sets in. If you need to move an established plant during the spring or summer, you can still do so, but you should take extra care to make sure that the plant doesn't go into shock.

Frost Dates

Another factor to consider when deciding when to plant perennials is your area's average last frost date. This is the date when you can assume that there won't be any more frosts or freezes until the fall. Most perennials prefer to be planted in the ground after the last frost date has passed. You can find out your area's average last frost date by checking with your local gardening center or by doing a quick Google search.

If you're not sure when the last frost date is, you can also check the soil temperature. You want the soil temperature to be at least 50 degrees Fahrenheit before you plant your perennials. If the soil is too cold, it can stunt the growth of your plants or even kill them.

Weather Conditions

Lastly, you should consider the current weather conditions when deciding when to plant perennials. If the temperatures are consistently hot and dry, it's not the best time to plant new perennials. They'll struggle to establish themselves in the heat, and you'll have to water them more frequently to keep them from drying out.

On the other hand, if your area has been experiencing a lot of rain or high humidity, it's also not the best time to plant. The excess moisture can cause root rot and other fungal diseases that can kill your new plants.

Conclusion

In conclusion, the best time to plant perennials can vary depending on several factors, such as whether you're planting new or established plants, the last frost date in your area, and the current weather conditions. By taking these factors into consideration, you can ensure that your perennials have the best chance of establishing themselves and thriving in your garden or landscape. Happy planting!
