How to propagate Petunias through cutting
A comprehensive guide on how to propagate Petunias through cutting and related knowledge about the timing and methods for cutting Petunias, let's find out together.
If you already have potted Petunias at home, you can choose to propagate them through cutting, which can save the cost of seedlings and is easy to learn with a high survival rate. In spring and autumn, choose good cuttings for propagation, which has a higher survival rate than in summer. Below are the methods for propagating Petunias through cutting.
I. Cutting Time
The best time for propagating Petunias through cutting is spring and autumn. The survival rate of cuttings in summer and winter is not high. If you want to propagate during these seasons, you need to keep the indoor temperature between 13-18°C, which can also result in successful cuttings.
II. Preparing Potting Soil
The propagation medium for Petunias can be sawdust and garden soil, mixed in a ratio of 2:8 and mixed evenly, then sterilized and set aside.
III. Choosing Cuttings
From vigorous Petunia plants, choose healthy branches free of diseases, cut them with sterilized scissors to about 10-15 centimeters long, avoiding old branches. Remove the leaves at the base, retain 1-2 leaves at the top, cut the bottom at a diagonal angle, soak in root-promoting water for 40 minutes, and then place in a shaded area to dry.
IV. Planting Cuttings
Prepare a suitable pot, not too large, fill it with potting soil and smooth the surface. Make some holes in the soil with a tool, insert the Petunia cuttings into the holes, and slightly press the soil around them. Water the pot, and place it in a well-ventilated area for care. The temperature needs to be controlled between 15-25°C. If the temperature is too high, it needs to be lowered promptly. Once rooted, they can be transplanted.
