Transplanting Perennials During Growing Season

When it comes to planting and transplanting perennials I prefer to plant in the fall or spring months. The weather is more suitable  in the spring, cooler days and the rainy season provides the hydration that newly planted perennials need to develop a strong root and to grow into healthy plants.  That is not to say that you cannot transplant or plant in the summer.  It can be done but the summer plants need tender loving care.  

Today I received word that all of my foundation plants needed to be moved; Hosta garden with fern and toad lilies.  My black-eyed Susan, and my rose garden also  need to be moved 10 feet away from my homes foundation. In the front I have my Liriope border grass also needs to be transplanted, presently it is growing next to the sidewalk and is in the line of fire from construction workers. 

My yard and garden has been set for the last several years and now I need to transplant 30 hosta, 12 fern, 24 liriope, 12 toad lilies, 6 roses and a 10 x21 square feet wildflower garden and all plantings must be completed by the end of June or they will be trampled by excavating equipment and foot traffic.

The first thing that I did was look over my preexisting garden to see if there was any room for the perennial transplants.  There was enough room in the back garden to transplant the wildflowers.   

The hostas would be moved into a garden that will encircle an oak tree. Rose bushes will be planted in clay pots and the border grass will be given to my neighbor so they can plant along their walkway.

When it comes to planting in the summer I prefer to transplant in the late afternoon or on a cloudy day.  This will reduce transplant shock. 
I also think it is a good idea to plan to transplant on a day when rain is in the forecast.  Tonight there is a 40% chance of rain so I am transplanting perennials.


A perennial that is planted during the summer months requires tender loving care.   I recommend planting in well drained soil that has been amended with compost.  Break up the clumps of soil so that the soil is loose and mix with all purpose continuous release plant food.  

 After perennials have been planted apply 3 to 4 inches of organic mulch.  This mulch will aid in keeping the roots cool and retain moisture. 

Set up a soaking hose to keep the soil evenly moist.  A faucet timer is helpful as transplants in summer need  a lot of hydration.  I water 1 hour in the morning and 1 hour in the late afternoon. 

Check the soil around the perennials daily to make sure it is evenly moist.

Great post! Transplanting perennials can be so tricky in the heat of summer. Just one more fun tip if you have any chronic wilters after the move -- cover with an overturned cardboard box. The shade from the box will help reduce respiration / transpiration while the plant gets established. After a few days, remove the box for morning sun and replace for afternoon shade. After one week, the plant should be fine.

Amanda Plante...Thank you for the helpful tip. I like the shelter from a cardboard box idea. So far the the transplants are okay. I moved them on a cloudy day, followed by a nice rain and today is sunny and cool. Tomorrow back into the 90's and I will follow your tips.
