You can plant most SunPatiens varieties from seed.
What temperature is ideal?
A SunPatiens seed requires a certain temperature range in order to germinate. Outside of this optimum range, germinating your SunPatiens seeds is still possible, but your success rate will be less.
Most plants’ ideal temperature range to germinate is 68 – 86 degrees Fahrenheit.
When to sow the SunPatiens seeds
Choosing the best time to sow your SunPatiens seeds depends on when you are planning on planting them outside.
Typically, SunPatiens seeds should be planted 6-8 weeks before you plant to plant them outside. Check your seed packet for the specific timing of your planting.
It’s definitely possible to plant SunPatiens outside of this window, but you may need to nurture the plant more inside before it’s warm enough to plant it outside.
Knowing when to plant an annual outside can be tricky, so make sure it’s not too early in the season when you plant your SunPatiens outside.
How long will it take for SunPatiens seeds to germinate?
Your SunPatiens seeds should germinate 7-14 days after they are planted.
This timeframe may change depending on how consistently you are keeping the soil moist and in the light. A seed that isn’t well taken care of will take longer to germinate or die before ever sprouting.
How to plant SunPatiens from seed
To plant SunPatiens from seed, you can follow the following steps
1. Purchase the SunPatiens seeds & potting soil
This can be done at many garden centers or greenhouses. If seeds are not available this way, many online stores offer SunPatiens seeds for sale.
Your SunPatiens seeds will grow best in potting soil rather than topsoil, so make sure to purchase some potting soil to plant the seeds in.
2. Find a container to plant in
You’ll need a container for your soil and SunPatiens seed. Seeds do not need much space to grow. In fact, you can plant multiple seeds in the same container and then separate the sprouts once they germinated and plant them in their own spot.
For a home solution, egg cartons or egg trays can be a good place to plant seeds and have them sprout. These containers provide more than enough room for a seed to germinate.
3. Plant your SunPatiens seeds
To plant the SunPatiens seeds, fill your container with potting soil. No need to fill it to the brim, as water runoff may overflow the container.
Now it’s time to plant your seed. The general rule of thumb with seeds is to plant them 2 to 3 times their length. You’ll want to error on the side of not planting them deep enough.
To plant the seed, you can poke a hole in the potting soil with your finger, or use a stick.
Cover the seed up with potting soil once you have placed the SunPatiens seed in the hole.
4. Water your newly planted SunPatiens seed
Water the SunPatiens lightly. Be careful not to overwater it. A SunPatiens seed only needs damp soil to begin its germination.
Transplanting SunPatiens seedlings
After the SunPatiens seed has sprouted, you can transplant it into another container.
To do this, push your finger down below the sprout and gently pull up so that minimal roots are damaged.
Once you have a free SunPatiens sprout, you can plant it in another container and gently water it in.
