Ideal Time to Transplant Avocado Seeds into Soil

After 4 weeks of transplantation, you should at least get a good sprout from the seed. But in some cases, it can take up to 8 weeks. So, try to be patient as a young plant starts to sprout from the avocado seed.

When you get a proper sprout with solid root structure and the stem is 15 cm in length, cut it back to about 8 cm long. After this cut, it will start to grow again. When it reaches 15 cm, this is the ideal time to transplant the seed from water into the soil.

How to Transplant Avocado Seed into Soil:

  • First take a 6 to 8 inches pot in which the avocado seed should be transplanted. Make sure that there are enough drainage holes at the bottom of the container. Otherwise, there is a chance for the plant to get overwatered that will result in root rot.

  • Put a mixture of garden loom or potting soil in one part, perlite, or vermiculite in the second part and peat moss in the third part. This mixture will make the soil lightweight for good air circulation and adequate water drainage.

  • Position your avocado seed in such a way that the roots spread out into the soil and the top of the seed doesn’t get covered by the soil completely.

  • After gently placing the root, fill around the root structure with soil. Take utmost care not to injure the root system. Do not put excess pressure while feeling in the soil. Otherwise, this will create inadequate air pockets inside the soil resulting in poor drainage.

  • Keep watering your plant until the water runs through the bottom of the feet smoothly. Try to keep the soil moisture good but don’t make it too soggy. You can continue the watering process once or twice a week, depending on when the soil dries up.

  • You can always use fertilizer to boost the growth of the plant. Most gardeners recommend using Nitrogen, Phosphorus and Potassium in a 10:10:10 ratio. In addition to natural light and atmosphere, these fertilizers will enhance the nutrition consumption of the plant.

  • Place your avocado plant in such a location that receives enough sunlight. You can place it near a window that is directed east or west.

Should I Transplant Malnourished Plants?

If the leaves look beautiful green and healthy, then you can just keep the plant in water. There is no need for transplantation. But as soon as the plant starts to show any sign, for example, if the leaves start to become yellow or the tip of the leaves start growing brown or become curly, you should immediately transplant the avocado plant in soil. Any of the symptoms mentioned above indicates that the plant is not receiving the adequate nutrients it needs. That is why, you have to transparent the young plant into the soil as quickly as possible.

Does an Overwatered Avocado Plant Need Transplantation?

  • As you grow an avocado plant inside a glass of water there is a chance that the roots may get overwatered. In this case, the plant will start to show symptoms indicating the urgency for transplantation into soil.

  • Check properly if the tip of the leaves has become brown or the nerve-like structures on the leaf start to become dark green and pale. Also, look out for any kind of yellowing or curling in the leaves. If you find out any of these symptoms it is obvious that the plant is being overwatered.

  • As you’re giving excess water and nutrients through the roots, the plant is trying its best to stop the photosynthesis process in the leaves to prevent the consumption of excess nutrition. Try not to transplant during cold winters, especially in the middle of the season. But if you don’t have any option, go for it.

How to Rescue a Dying Avocado Plant by Transplantation:

  • Try to perform the transplantation process in sunny and warm weather. Because if you transplant them in colder weather, the soil will tend to have less humidity and temperature resulting in a transplant shock. Then you have no shot to save your plant.

  • If your avocado is a houseplant, at first select a fair pot that is minimum 6 to 10 inches deep. If your plant is bigger, then a bigger pot would be suitable. Otherwise, you can use any smaller pot of your house that can fit the root system of the plant properly.

  • Use a soil scoop to drop soil in the pot both before and after the plant is being placed. As this is the first time your avocado plant grown in water is being transplanted into soil make sure that the soil height is at least 6 inches.

  • Don’t grab the plant by its seed to pick it up. In many cases when you try to pick up by holding the seed there is a chance that they will break apart. Always remember that even at this stage, the seeds act as a storage area of nutrients for the plant. So, it is better to pick up the plant holding the stem.

  • Use your hand to make a small hole at the middle of the soil and place the plant in that hole very gently. Don’t push the root against the soil too hard, that will damage the entire root structure.

  • Use the scoop to pour soil near the roots. Be careful not to pack it down.

  • Bury the seed just about a quarter way up from the bottom. Never bury the entire seed in this stage of transplantation. Otherwise, it will start root rot.

  • After the transplantation is done, you must water your plants. note that as your plant is already about to die never use cold water to provide hydration. If you use cold water, it will slow down the growth process much more resulting in a quick death. Therefore, always use room temperature water to help your dying plant grow quickly and become healthy.
