Hi, I'm Justin Hancock, a Costa Farms garden guru. I love Mandevilla and I bet you do too. These plants have gorgeous trumpet shaped flowers in stunning shades of red, pink and white. They flower all summer long and thanks to new advances in Mandevilla breeding, the dwarf mounding times as well as viners so you can grow them on trellises to help cover walls. If you buy a Mandevilla, here are easy tips to plant it so you can enjoy success all summer long. First off, slip it out of the pot. Now if your Mandevilla is really root bound you may find that this is a little tricky. If it's a plastic pot, squeeze hard. I sometimes put it in the ground and even squish it with my knee if it's really root bound. Once it comes out of the pot, you'll see how badly root bound it is. If the roots are circling on the inside of the pot like this, it's really important to help spread them out. So gently massage the root ball and spread the roots so that they're not all growing pressed up tight against the pot. Once your root ball is nice and loose, it's time to fill it with potting mix. Now I advise using a good high quality potting mix, don't use soil from your garden. Garden soil can introduce diseases, insects, pests and other problems. Plus it doesn't drain very well. So fill your pot with the potting mix. When selecting a pot by the way it's important to make sure that you have good drainage. Mandevilla don't like the roots sitting in water so a drainage bowl is important to allow all that extra water to escape. Also it's helpful to repot in a pot that's only a couple sizes bigger. You don't want to go to a huge pot right away, otherwise that can be stressful and shocking to your Mandevilla. Once you fill it up with potting mix, water it well, move it to a sunny spot and then simply enjoy the beauty all summer long.
