Hi, I'm new here and live in a 9B.
I'm about to plants a third tropical hibiscus. I have two others that are doing okay. They produce new flowers about other day as long as I stay on top of the deadheading. I have a new red one that I'm about to plant up against a east block wall in my back yard. Is against the wall and getting afternoon sun okay? I figured that this would be a good way to cover this unsightly wall and add color to that side.
What's the best way to plant this hibiscus in the sandy soil that we have? What should I amend/mix with the soil before and after?
I have a product called Ultrasol k Plus, it's NPK is 13.7 - 0 - 46.3. Since Hibiscus have such a great need for potassium, would this be okay to use also while planting? I have other products, yet this is the one with the highest potassium. Another I have is called "Gardner & Bloome Palm, Tropical & Hibiscus Fertilizer" 4-6-4, which seems rather weak.
Thanks.
