Phlox paniculata "David"
I have just bought a seedling of the above variety and wonder if it can be grown in a container. Also, How can I avoid mildew which has been a problem with my already established phlox of which I don't know the variety. Thank you.
Yes, and watering is the key to mildew prevention.
They will take a couple of seasons to get established so it might be worth growing them on a bit in plant pots to grow a good root system before you plant in the garden. They stand and a better chance of surviving if you do. Once they are big enough to plant in the garden I would give them a good mulch of compost to retain moisture. Mine have taken 3 years to be fully established, but worth persevering with them.
Life's tragedy is that we get old too soon and wise too late.
Thats good advice, Thank you I'll do that. Where I live the soil is a sandy so I will buy some good compost and I think there's something called Rootgrow. The plant is only a baby in a 9cm x 9cm pot so if I graduate the pots over a few months, It should be successful ? and then ready to put in the ground. Thank you.
