HOW TO GROW ICE PLANTS FROM SEEDS
Ice plants are drought-tolerant succulents and they can perform well in poor soil. Another thing that you have to keep in mind is that these plants are invasive. So plant them by considering this.
Ice plants can be grown by multiple methods like growing from cuttings or using the division method. But in this article, we are going to see how we can grow this plant from seeds.
Follow the steps given below to get the best results.
- First thing first, you need to get some good quality seeds from your trusted plant store. An average or low-quality seed would possibly not germinate at all.
- To germinate these seeds, use seed starting trays or small-sized plastic pots. It’s better to start the plant in a container so that you don’t have to disturb the plant. This is needed only when you want to grow the ice plant in containers.
- Fill the pot or tray with good-quality potting soil. Make sure the soil also has good drainage. This is important for the germination stage but once the plant is established, it doesn’t get affected by poor soil.
- It is recommended to pre-water the soil to let it adjust properly and not remain too dry when you are starting the new pant.
- You have to leave a quarter-inch space between the soil and the top of your container or pot.
- Now add some gravel on top of your soil.
- When are you planting your ice plant? This is the important question and the answer should be that you have to sow the seeds 4 to 6 weeks before the last expected frost so that you can transplant them outside at the best time.
- Now add some seeds to the gravel and let the seeds reach the soil by tamping slowly.
- There are two most important things that you need to keep in mind while sowing the ice plant seeds.
- First of all the seeds must not get covered by soil or gravel. They should only touch the soil.
- The second important thing is that sunlight must also reach properly to the seeds. This means your chosen location must get enough sunlight. If you fail in this step, don’t hope for the seeds to germinate.
- Indoor planting of ice plants is also dependent on light. Choose the spot that gives plenty of sunlight. Also, the temperature must remain above 60 degrees Fahrenheit.
- There is also another way of sowing the seeds in the soil. The technique is called tilling. It is easy to use when you are growing in containers.
- In this method, you can use a small stick and start gently pricking your container soil with it. You are hard on it as excessive tilling is harmful to the soil.
- Now sprinkle the seeds on the soil.
- These seeds must not be buried in the soil and should remain over the soil surface.
- You can add a very thin layer of sand if you desire.
- Now it’s time to spray water on your ice plant seeds to keep the moisture level required by your seeds to germinate.
- Soggy soil or too much watering would surely cause problems for you.
- The watering routine should continue like this till your see new plants sprouting out. Just keep them moist only.
- At this stage, you must be having a bunch of very young little seedlings of ice plants.
- Now if you plan to move them outside in your main garden space or outdoor garden, you need to harden them off.
- On the first day only keep the small plants in direct sunlight and under outdoor weather conditions for one hour only.
- Next day you can add half an hour more to the previous day’s time.
- Similarly, keep on increasing this exposure time. Keep this practice for about 2 weeks. This process is known as hardening off.
- After you are done hardening them off, you are good to go to transplant them outdoors.
- One last thing before planting them outside is to make sure that the frost danger has passed.
- By keeping one and a half feet of distance between each new plant, you can transplant them in full sunlight.
- Once the plant is established, no more care is needed. Not even regular watering routines. They are drought tolerant.
- You also don’t have to worry about adding any kind of fertilizer to your soil, they can give good results in poor soil also.
- Now sit back and watch the beautiful eye-catching flowers growing in your garden space.
