Pests
Aphids and whiteflies are the primary problem pests with Diascia.
Disease

You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.
Planting Trinity Sunset Liners
We recommend 1 starter plant per 4 inch pot or 1801, or 3 starter plants evenly spaced in a 1-2 gallon container. Use a well-drained soil in your pots and plant your liner deeply directly in the middle of your pot. Cover the ellepot completely with soil..
One pinch about 10 days after transplanting to your final container should be sufficient.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
