When Is the Best Time to Grow Phlox?

It is not easy to determine the end of frost. She further recommends that you ask at your plant nurseries in the zone or refer to the farmer’s almanac to determine the last days of frost.

Step One: Choose the variety of phlox that you want to grow

Do some research on what kind of phlox you are looking for! Phlox can come in a daunting number of colors and sizes, and what you choose will depend on your needs. For instance, there is phlox variety tall that is usually used as fence lining. Some of them are dwarf plants that are essentially mildew resistant. There is a choice with colors too. You could choose the one that suits your garden furniture and aesthetics better.

Step Two: Choosing the right location

Phlox needs a place to grow where it can get a proper amount of sunlight. Some of the varieties could also do with lesser light or filtered light. However, there is always a risk of contracting diseases if the plant receives less sunlight. It is also seen that they produce fewer buds.

The amount of sunlight that your phlox needs will significantly depend on the variety that you have chosen. In case you have opted for a phlox that is going to be planted in the shade, look particularly for a variety that is mildew resistant.

Step Three: Do the soil test

Phlox requires a lot of moisture in the earth, but the last thing it needs is waterlogging. The simplest way to determine if a spot in your garden is going to be ideal for growing them is to examine it after heavy rains. If the water stands and stagnates, be wary. But if the water is absorbed and the soil is well-drained, go for it.

Step Four: Plant the phlox

Dig holes that are twice the size of the ball roots of the phlox plants. If you are planting multiple plants, make sure to have at least one to two inches of space between them to encourage ventilation.

Gently set the phlox plants into the earth without hurting the roots and pat the earth around it. Water the plant extensively for the first time.

Step Five: Water the plants well throughout the growing season

Dryness in the soil can affect the plant adversely. Always water the plant at the bottom. Excessive water on the leaves and stem can encourage the growth of mold and mildew.

Step Six: Use a good fertilizer

Using a fertilizer or plant food that has a 10% potassium, 10% nitrogen, and 10% phosphorous. Repeat the fertilization once again at the flowering stage. Every alternate year, it is recommended to add manure to the soil.

Step Seven: Mulch the plants

Once the summer begins, mulch the plant extensively. Mulching will help in keeping moisture in the soil intact and also ward away unwanted critters.

Step Eight: Prune the plants

Let only 6 to 7 stems on each plant. This will increase air circulation and prevent diseases. Pinch the stems to discourage quicker growth. Remove the dead flowers. In some varieties, newer blooms will come when you discard the dead flower heads.

Step Nine: Protect your phlox from diseases

Make sure that they get adequate sunlight, air, and water. Remove the dead foliage and water early mornings disciplinarily. Remember to remove all the mulch by autumn; otherwise, rot and fungus will overtake.

Step Ten: Protect your plants from the phlox bugs
