In case you still want to incorporate fertilization to your plant care routine, add fertilizer to the soil before planting. Already established plants should be fertilized in early spring.

Potting & Repotting
You can plant your Hypericum plant anywhere from spring through fall. Here are the step-by-step planting instructions:
- Prepare the bed: Break up the existing soil to 12-16 inches deep. To improve drainage and add some extra nutrients to the soil, add some organic matter. You can add manure, peat moss or garden compost for this purpose. It is recommended to add fertilizer to the soil before planting to encourage blooming. Add a granulated or all-purpose fertilizer labeled 5-10-5.
- Position your plants: Accord to the spacing and height suggestions on the plant label, position your plants. This might cause some headache, but what you aim for is to put your taller plants in the center or in the background of the landscape. This way shorter plants will be placed in the foreground, creating a beautiful aspect.
- Remove the plants: Gently remove your plants by bracing the base of the plant, tapping the outside of the container to help the soil loosen. You can rotate the container while tapping continuously until the plant pulls from the pot.
- Dig the hole: Try to dig a hole two times larger than the roots ball. Gently rake the roots apart and place the plant into the hole.
- Cover the planting hole: Fill the empty space around the root ball. Make sure that the soil is even with the surrounding soil. You can also add a thick layer of mulch to help the soil retain moisture.
