Checkbox-imageBOOST YOUR SOIL

One of the best ways to be successful when planting this fall is to amend your soil (50% soil amendment to 50% original soil). Then seal in moisture with a fresh layer of Altum’s Hardwood Mulch.


The time is now, my friend. Perfect conditions, less watering, less stress on your plants and healthier plants come spring. Remember the root ball should be level with the soil line and the wider the hole the better—loosens the soil and gives roots room to grow. Check out the Step-by-Step Planting Guide. We have great results with Fertilome Root Stimulator, too.


If you buy bulbs now while the selection is good, then  strategically plant them (with some Dutch Bulb Food) when the ground has cooled come October, you’ll be in for a lovely spring surprise.

Put together your own concoction of mums, pumpkins, pansies, ornamental grasses, seed pods, curly willow branches, cabbages and kale in containers, windowboxes or beds.

Let’s grow together. Stop in, call 317.733.GROW and find what you need online.
