Are Sunpatiens perennials and will they grow in the shade?
Sunpatiens are perennials in zones 10-15. All other zones they are grown as annuals.
You may plant your Sunpatiens in shade or sun.
I have a pot of Sunpatiens that have tons of leaves but no blooms. i used potting soil with fertilizer in it so I don't know if I should fertilize.
The fertilizer that comes in potting soil usually isn't very high in Phosphorus or Potash which is what the plant needs to encourage new flower development. Look for a fertilizer that is safe for potted plants and that is higher in Phosphorous and Potash than Nitrogen. When looking at the label look for a fertilizer that has higher 2nd and 3rd numbers than the first. The first number is your nitrogen and is used predominantly for foliar development.I think Miracle Gro makes a flower fertilizer or look for something like Super Bloom which is a water soluble fertilizer. Feed according to label instructions preferably early in the morning and make sure the plant isn't dry at the time of fertilization to assure you will not burn the plant. I usually water the day before I feed my plants and then water after the application of the fertilizer to water it into the root zone.
If you potting mix had a slow release fertilizer, that should be enough fertilizer for your plants.
To much nitrogen will actually inhibit flowering.
Make sure the soil is evenly moist.
You can add a small amount of Phosphorous to encourage blooming. Bone Meal will work for this.
My red sun patients get white edges almost like bleaching. What can I do to avoid this. They get intense sun for a couple of hours in the afternoon
Avoid overhead watering or splashing unto the leaves.
The plants are still growing and I have rooted some cuttings also, but nothing blooms.
They may have been stressed from heat, humidity. Did you protect them from frost over winter? If not, that probably did them in. If they suffered heat stress, fertilizinng, watering and cutting plants back by about a third should revive them in a few weeks.
I brought my sunpatiens into the house about 3 weeks ago before any signs of frost. The leaves appear to be discolored and it appears to have some type of insect problem. I have attached a couple of photos, I am hoping that you may be able to help me with a solution to my problem please?
The first photo looks like spider mite damage but the second photo looks more like mealy bugs (unless it is spider mite webbing). To treat both you can spray with Neem oil.
Can Sunpatiens be planted successfully under a Black Walnut tree?
Unfortunately not. They are not juglone tolerant. You do have quite a few options, though. This article will help:
