Propagating Supertunias: A Comprehensive Guide To Growing These Vibrant Plants

What are Supertunias?

Supertunias are a type of flowering, perennial petunia that is part of the Solanaceae family. They have been developed from classic petunia varieties and come in a wide variety of colors, sizes and shapes. A few sub-varieties include Pixie, Wave Petunias, Surfinia Petunias and Mirage Petunias. This hybrid flower is remarkably easy to grow and create lovely displays with vibrant colors for any garden or outdoor space.

How to Propagate Supertunias

Propagating supertunias is relatively simple as long as you know what steps to take. The faster you can propagate them the better since they tend to be somewhat sensitive when it comes to weather conditions like heat or cold temperatures. Here’s how:
1) Start by gathering your supplies: scissors; rooting hormone; pruning shears; vermiculite (or other rooting medium); potting soil; plastic pots with drainage holes at the bottom
2) Cut off several young stems from an existing plant that has abundant growth using sterilized scissors (dip blades in rubbing alcohol before each cut). Each cutting should consist of 4-6 leaves on top and 8 inches below the tip (including 1 inch of stem attached). Make sure no flowers are present on each cutting
3) Dip lower ends into root hormone powder before placing them in individual containers filled with moistened vermiculite/rooting medium mixture or perlite mixed with peat moss for better aeration – this will encourage root growth
4) Place containers inside clear plastic baggies then place them in indirect sunlight indoors until new shoots appear – this could take up 10 days depending upon temperature & humidity levels outside
5) When roots begin appearing, transplant clippings into fresh potting soil mix immediately so they become well established over time – add organic fertilizer after planting if desired

Tips For Caring For Your New Plants

After propagating supertunia plants it’s important to care for them properly while they establish themselves outdoors: • Keep plants well watered but avoid overwatering as this can lead to root rot & diseases • Fertilize every two weeks during their first year • Pinch back stems regularly throughout season especially between spring summer months so plants stay bushy & full looking • Prune back mature blooms frequently throughout growing seasons help keep shape intact & promote more flower production
