How To Grow An Avocado Tree from Seed
Step 2: All avocado pits, despite not being perfect round shapes, have a top and bottom side. From the ‘bottom’, the future roots will grow, as for the ‘top’ the sprout will do the same. You can find which is which by looking after the slightly pointier end. When you noticed that, you found the top. In opposition, the bottom will have a flat end. It’s important to place the bottom in water, so the roots will begin to gently grow.
Step 3: Next, stick 4 toothpicks into the top side of the avocado seed. Make sure the injections are made pointing down at a slight downward angle and are spaced evenly around the circumference. Wedge the toothpicks strongly because they will allow you to place your avocado base in the water but still have the fruit hanging over a glass.
Step 4: Place the glass with the half-submerged avocado in a place with sunlight. Use a clear glass for this operation, so you can observe when the roots start to grow. It’s useful for warnings of mold, bacteria and fungus growth, so you can change the water when it’s needed. You can do the latter regularly every day, as many professionals recommend, but it’s better to change the water every 5-7 days.
Step 5: Sprouting can take as long as 8 weeks, although many websites suggest only 2-4 weeks. The best advice is to be patient. And pay attention so the seed goes to the necessary stages of sprouting: the outer brown seed skin will slough off as the top of the avocado pit will dry out and form a crack; the crack will extend and to the bottom side of this, a tiny taproot will begin to emerge; this will grow longer and longer until a small sprout will peek through the top of the avocado pit. Don’t forget to maintain the taproot submerged, because not doing so will be synonymous to the death of your plant.
Step 6: There are a few tricks when it comes to planting the newly born sprouts. When the stem reaches 6-7 inches in length, cut about 3 inches off it, as this will make the new part grow faster. Cut and put it in a rich humus soil pot, when it has reached 6-7 inches again. Use best with an 8-10inch diameter pot. Before placing in a sunny area, make sure that you leave the top half of the seed exposed.
Step 7: In this stage of planting your own avocado, you need to know two things about its relationship with water: the soil should always be moist. If you start to see yellow leaves, it’s a sign you exaggerated and over-watered it. No need to panic though. Let the plant some time to absorb the water and continue after it has dried.
Step 8: Encourage the plant to grow larger, by pinching out the top two sets of leaves. Do this when the stem has reached about 12 inches in height. Repeat the method when another 6 inches have grown additionally on the plant.
Step 9: If you happen to come across some nasty bugs, like aphids, you will need to wash them off the avocado. You can do this by showering or gently hosing down your plant. When there are no more pests on it, spray the avocado tree with a solution of water mixed with a few drops of dishwashing liquid and one teaspoon of neem oil. Check in 4-5 days to see if it’s clean. If not, repeat the process until it is.
Step 10: In the autumn or winter, if it gets cooler than 45 degrees F, you must bring the baby avocado tree indoor, so it won’t freeze to death.
