Planting/Care Instructions

Before planting, have your soil tested to see what amendments are needed. Click this link to check your frost dates: Frost Dates. Check the light preferences for your plant and choose your plot accordingly. Even if you have the perfect soil and ideal location, you still need to choose the right time of the year depending on what you are planting.

When you receive your plant, soak the root ball in water for 20 minutes upon arrival before planting or potting. Gently break up the root ball. This will help the roots of the plant to grow out into the soil. Dig a hole slightly larger than the root ball of your plant. Fill in the hole tightly with soil to avoid any air pockets. Add a bit of slow-release fertilizer to help new plants to grow quickly. Add the recommended amount per fertilizer instructions. Be sure to water your plants. In addition, pull weeds out when they appear. They take nutrients from the soil.

Additionally, certain plants may need staking. Whenever they become too heavy to stand on their own, add bamboo stakes for the plants to lean against or tie up for support.
Prune plants as needed to encourage growth. If you have trouble keeping up with your pruners, check out our locally hand-made leather pruner holster here.

Lastly, enjoy your Kumson Forsythia and your time in the garden!

Please Note: We currently do not ship plants to Alaska, California, Hawaii, Oregon or Washington. These states have strict shipping regulations against pests from other states. Extended transit time is also a factor in this decision. We are sorry for the inconvenience. Many factors influence which plants will thrive in a given location. Heat, cold, and elevation are just a few that can have a big impact.
Plants may have been recently potted up and have not completely rooted in. Please grow them in the pots one full growing season, before planting in the ground or potting mix may fall off of the root ball.

I wasn’t sure how bareroot plants would do!

They did super well! And in the peak heat of summer. The plants were just beginning to bud when I put them in the ground.

Kumson forsythia purchase

This shrub is not easy to find. Locating it here AND at a very reasonable price was great. All aspects of ordering and delivery were painless. Very happy with the size and quality. It’s now growing well in the garden. Will be back in the fall to look deeper into their offerings.
