Summer is great time to plant perennials. Whether it's filling in an empty spot in the garden, moving a plant from one location to another or maybe you just moved into a new home and want to get your landscape started, or you've got the week off and want to work in the garden. The simple answer is yes, you can plant perennials this time of year. Your plants will survive and thrive if you keep these things in mind. Do your actual planting during the coolest part of the day. Early morning is usually best, though late afternoon into early evening will work, if it's cloudy. Do the hard work in advance. Get the planting spot ready by digging the hole as deep and twice as wide as the container your plant is in. Improve the planting site by adding organic material such as Sheep, Peat and Compost, peat moss, compost or coconut coir to the hole and to the dirt you just dug out. Mix the organic material 50:50 with the existing soil or roughly half. This is called "amending the soil" and products such as compost, peat moss, coconut coir, aged manures are called "soil amendments". Adding amendments will make our typical clay soils more useable to the plant. Amendments allow the clay soil to drain better and frees up nutrients in the soil. Once the hole is dug and amended, fill it with water and let the water drain. Do this twice, before you plant. This will ensure the soil around the plant's root ball is wet. If you want to add some Root Stimulator, now is the time to do so. Water your plants thoroughly before planting or transplanting them.
