Sarah Pryor tasted her very own garden fresh carrot as a little girl, and she has been chasing the thrill of growing fresh produce ever since. She shares her planting tips, frugal projects, and canning madness on her blog, Coffee to Compost.

Summers can be so hard on flowering plants. Torenia continues to bloom heartily, even in hot and humid summers. It is easy to propagate too.

The technique of rooting in water is a simple propagation technique that ensures enough moisture gets to the stems, and lets one check the progress without digging!

First, cleanly clip some cuttings. Cuttings at least 6 inches long are best.  Remove the leaves that will be below the water line. Leaves submerged in the water will rot and pollute the water.  If possible, have a node at the bottom of the stem. Roots usually come from nodes (spots from which branches or leaves grow) first.  Some also remove flowers and buds; but torenia will root, even with buds.

Once they have a good start on a root system, they can be planted in a pot of homemade compost or potting soil.  Harden off the wishbone flower for a few days by keeping it watered and shaded, then plant.  Other plants that can be propagated using this method include basil, oregano, coleus, sweet potato, and tomato.

    I read hibiscus can be propagated in water with a little bit of Hydrogen Peroxide, I want to say a table spoon per gallon of water but google it because I’m not positive. I read that you want to take green cuttings (new growth) in the middle of summer and place them in the water with all but the last two leaves on top removed. Like the author of this article stated, do not let any leaves touch the water. If the top two leaves are large then cut them horizontally in half. Then cut at a 45 degree angle, near a node is best, like stated above. You can use a rooting hormone but it is not necessarily needed in order to root the cuttings. Any brown or dark green stems can be rooted but you have to place them in soil. The cuttings will develop white roots in the water. The roots will turn light brown with age. At this point you can place the rooted cuttings in potting soil or whatever soil you like best.

    Hi, i am a novice gardener.i have two torenia pants. When I bought them they has plenty of flowers. The media was bad so i re posted them. That was 3 weeks ago. They had flowers for a week or so after that buds started to drop before becoming flowers. I had them in shades first but now I have them in direct sun light. Buds are forming but no flowers. What am i doing wrong? Please help.

      You need well drained soil and full sunlight. However do not allow the soil to dry out. Keep it moist but not wet.

      I use a mixture of potting soil, perlite and peat moss on my balcony pot.
