Growing an Avocado From Seed Q&A

Q: Can I grow an avocado tree indoors year-round?

A: Yes, you can! But keep in mind, avocado trees need a lot of light. Make sure to place it in a sunny spot (preferably south-facing) or use a grow light to help it thrive indoors.

Q: Are avocado trees self-pollinating?

A: Yes, avocado trees are self-pollinating, meaning they don’t need another tree to produce fruit. However, having two trees can improve fruit production by increasing pollination.

Q: How much space do I need to plant an avocado tree?

A: Avocado trees need a lot of room to grow—expect them to reach 30-40 feet tall and 20-30 feet wide! Be sure to plant them at least 15-20 feet away from other trees, structures, or fences to give them room to spread out.

Perennial Herbs For Your Garden Q&A

Q: What’s the difference between a perennial and an annual medicinal herb?

A: Perennial herbs come back year after year, so once you plant them, you’ll have them for a long time! Annual herbs, on the other hand, only last for one growing season, so you’ll need to replant them each year. Perennials like mint, echinacea, and yarrow save you the hassle of replanting every spring.

Q: How can I harvest medicinal herbs without killing the plant?

A: The key is to harvest selectively! Only take what you need from each plant—this lets it continue to grow and regenerate. For herbs like mint and sage, you can snip off the top leaves regularly to encourage fresh growth. For larger plants like echinacea or valerian, cut back the flowers once they’ve bloomed to keep the plant healthy.

Q: What’s the best way to use my herbs for medicinal purposes?

A: There are tons of ways to use your medicinal herbs! Fresh leaves can be used in teas, tinctures, or poultices. Dried herbs ar

Early Spring Blue Flowers Q&A

Q: Are early spring blue flowers annuals or perennials?

A: Most early spring blue flowers like Crocus and Iris reticulata are perennials. They come back every year, giving you reliable, beautiful blooms each spring. However, some, like Scilla and Chionodoxa, are typically planted as perennials, too, but depending on your climate, you may treat them as annuals if they don’t come back reliably in colder areas.

Q: Aside from blue flowers, are there any white flowers that bloom in early spring?

A: Absolutely! If you’re looking to mix things up, there are some gorgeous white flowers that bloom just as early as blue ones. Snowdrops are a classic—these delicate flowers pop up right when the snow is melting. Anemone is another great option; it has simple, pure white blooms that are perfect for adding a clean, crisp touch to your spring garden.

Q: What’s the best way to combine white and blue flowers in my garden?

A: For a stunning contrast, try planting blue ones like Crocus and Iris reticulata next to white ones like Anemone or Lily of the Valley. The combination of the cool blues with the fresh white blooms will create a striking visual impact. You can also create a natural look by planting them in clusters or drifts across your garden.

Best Types of Avocado Tree

There are a bunch of avocado varieties, but here are some of the best ones to grow:

Hass

The OG. This is the most common avocado you’ll find in grocery stores. It has a rough, pebbly dark green to black skin and a rich, creamy texture that makes it perfect for guacamole and spreads. It’s a highly productive tree that thrives in warm climates and can tolerate some cooler temperatures. If you’re looking for an easy, reliable avocado, Hass is the way to go.

Fuerte

This variety is larger and smoother than Hass, with a slightly thinner, glossy green skin that stays green even when ripe. It has a nutty, buttery flavor and is known for its excellent quality. Fuerte avocados are one of the best cold-hardy options, making them a good pick for growers in areas with mild winters. They also tend to have a longer season than Hass, providing fruit in fall and winter.

Bacon

No, it doesn’t taste like bacon (unfortunately), but it is one of the best choices for people in cooler climates. It has a smooth, thin green skin and a milder flavor compared to Hass. The tree is highly productive and grows well in areas where other avocado varieties might struggle due to colder temperatures. If you’re outside of the usual avocado-growing zones, Bacon might be your best bet.

Reed

If you like large, creamy avocados, this is a great choice. Reed avocados are bigger than Hass, with a round shape and thick, slightly bumpy skin that stays green when ripe. They have a buttery texture with a slightly sweet flavor. One of the best things about Reed avocados is that they don’t ripen all at once, so you can leave them on the tree for longer and enjoy fresh avocados over a longer period.

Pinkerton

Pinkerton avocado tree

A solid option for small gardens or container growing. The Pinkerton avocado tree stays relatively compact but is still highly productive. The fruit is long and pear-shaped with a slightly pebbly green skin that darkens as it ripens. It has a creamy texture and a rich flavor similar to Hass. If you’re growing in a limited space but still want a good fruiting tree, Pinkerton is a fantastic choice.

When and Where to Plant Your Avocado Tree

When

The best time to plant an avocado tree is in the spring, right after the last frost has passed. This gives the tree plenty of time to establish strong roots before the hot summer months or colder winter temperatures roll in. If you live in a tropical or subtropical climate, you can plant year-round, but spring is still ideal for the best root development.

Where

Outdoor Planting

If you live in zones 9-11, plant your avocado tree outside in a sunny spot with at least 6-8 hours of direct sunlight daily. These trees get big (30-40 feet tall), so give them space—at least 15-20 feet from other trees and structures. Choose well-draining soil to prevent root rot, and if your yard retains water, plant on a slight mound. If you’re in a windy area, use a windbreak to protect the branches and fruit.

Indoor Planting

For colder climates (zones 8 and below), grow your avocado in a large pot with drainage holes. A dwarf variety like Wurtz (Little Cado) is best, as it stays under 10 feet tall. Place it near a south-facing window for 6-8 hours of sunlight, or use a grow light. Keep temperatures between 60-85°F, away from drafts or heaters.

How to Plant an Avocado Seed

Growing an avocado tree from seed is a great learning experience, but it requires a lot of patience. Seed-grown trees can take 5-13 years to bear fruit, if they ever do at all. If you’re okay with the wait (or just want a cool houseplant), here’s how to grow an avocado from seed:

Step 1: Prepare the Seed

  1. Eat an avocado – The best part of this whole process! Keep the large seed inside.
  2. Rinse the seed – Wash off any leftover avocado flesh with lukewarm water. Be gentle—don’t remove the brown outer skin, as it protects the seed.

Step 2: Set Up for Sprouting

  1. Insert toothpicks – Stick three toothpicks evenly around the middle of the seed. These will act as supports to hold the seed over water.
  2. Suspend the seed in water – Place the seed over a glass or jar of water, with the pointed end facing up and the broad, rounded end submerged in water.
  3. Choose the right spot – Keep the seed in a warm location but out of direct sunlight. Avocado seeds need temperatures around 65-75°F (18-24°C) to germinate.
  4. Change the water regularly – Replace the water every 2-3 days to prevent bacteria and mold growth.

Step 3: Watch It Grow!

  1. Be patient – Sprouting takes 3-6 weeks, so don’t get discouraged if you don’t see progress right away.
  2. Look for signs of life:
    • The seed will crack after a few weeks.
    • Roots will emerge from the bottom and grow downward.
    • A stem will grow from the top.
  3. Trim for stronger growth – Once the stem reaches six inches long, cut it back to three inches to encourage a bushier, healthier plant.

Step 4: Transfer to Soil

  1. Check the roots – When the roots are thick and the stem has leaves, the seed is ready for planting.
  2. Choose a pot – Use a 10- to 12-inch-wide container with drainage holes. If you’re planting outside, pick a sunny, well-draining spot.
  3. Use well-draining soil – A light, sandy mix works best. Avocados don’t like heavy, compacted soil.
  4. Plant the seed – Bury it halfway into the soil, with the top still exposed.
  5. Water gently – Keep the soil moist but not soggy. Overwatering can cause root rot.

📌 Note: Trees grown from seed are more for fun project than function. If you want homegrown avocados, go with a grafted seedling instead!

Planting Avocado From Seedling (The best choice to bear fruit)

If you want avocados sooner (3-5 years) and with guaranteed fruit, buy a grafted avocado seedling from a nursery. These trees are bred for fruit production and have a rootstock that ensures better growth and disease resistance.

Step 1: Choose the Right Seedling

  • Select a healthy plant – Look for one that is 12-24 inches tall with bright green leaves and no signs of pests or disease.
  • Pick the right variety – Some avocados thrive in warm climates, while others handle colder temperatures better. Make sure to choose the right type for your location.

Step 2: Planting Outdoors (Best for Warm Climates, Zones 9-11)

If you live in a warm climate, planting your avocado tree in the ground is the best way to help it grow large and productive.

  1. Find the perfect spot - The tree should receive at least 6-8 hours of direct sunlight daily. Make sure also to keep it 5-20 feet away from buildings, fences, and other trees
  2. Prepare the soil - Avocados prefer loose, well-draining soil with a pH between 6 and 7.
  3. Dig a proper hole - Make the hole twice as wide and just as deep as the seedling’s root ball.
  4. Plant the tree - Remove the seedling gently from its container. Then place it in the hole with the trunk base slightly above soil level to prevent rot.
  5. Water thoroughly - Give it a deep watering after planting. Continue watering 2-3 times per week for the first few months.
  6. Protect from wind and frost - If you live in a windy area, plant near a fence or use a windbreak. Young trees are sensitive to frost, so cover them with burlap or frost cloth in cold weather

Avocado Plant Care Requirement

Soil

Avocados hate wet feet, so well-draining soil is a must. Sandy or loamy soil works best since it prevents water from pooling around the roots. If your soil is heavy or clay-based, mix in some sand or compost to improve drainage.

Watering

Water deeply once or twice a week, making sure the soil soaks up moisture but isn’t constantly wet. Let the top few inches of soil dry out before watering again.  In hotter months, you may need to water more frequently, but always check the soil first.

Temperature and Humidity

These trees thrive in 60-85°F and prefer warm, humid conditions. They don’t handle frost well, so if the temperature drops below 50°F, either move your tree indoors or cover it with frost cloth to keep it warm.

Sunlight and Location

They love full sun and need at least 6 hours of direct sunlight daily to grow well. If you’re growing one indoors, place it in the sunniest window possible or supplement with a grow light to keep it happy. Outdoor trees should be planted in an open area with plenty of sunlight and protection from strong winds.

Avocado Maintenance Tips

Fertilizer

Feed your avocado tree with a balanced fertilizer (like 10-10-10) during spring and summer to keep it growing strong. Avocados also love extra nitrogen, so consider using a fertilizer higher in nitrogen for better leaf and branch development.

Pruning

Prune your tree in early spring to control its height and encourage branching for a fuller shape. If you’re growing an avocado tree indoors, regular pruning is a must to keep it from outgrowing its space.

Mulching

Spread a layer of mulch around the base of your tree to retain moisture, regulate soil temperature, and suppress weeds. Just make sure to keep the mulch a few inches away from the trunk to prevent rot.

Potting and Repotting

If you’re growing your avocado tree in a pot, you’ll need to repot it every 2-3 years as it outgrows its container. Always use a pot with drainage holes to prevent root rot. As the tree grows, gradually move it to a larger pot to accommodate its expanding root system.

Overwintering

If you live in a cold climate, bring your potted avocado tree indoors before the first frost. Keep it in a bright, warm spot away from cold drafts. If it doesn’t get enough sunlight, consider using a grow light to keep it happy through the winter months.

Common Pests and Diseases (And How to Handle Them)

Pests

  • Spider Mites: Look for tiny webs on the undersides of leaves. If you spot them, treat with neem oil or insecticidal soap to knock them out.
  • Aphids: These little pests often show up as clusters of small bugs on new growth. Blast them off with a strong stream of water or use insecticidal soap to get rid of them.
  • Scale Insects: Look for small, bump-like growths on the stems and leaves. Use a soft cloth to scrape them off and treat the area with neem oil for full control.

Diseases

  • Root Rot: Often caused by overwatering, root rot can quickly harm your avocado tree. To prevent it, let the soil dry out between waterings, and make sure your pot has proper drainage.
  • Anthracnose: This fungal disease causes dark spots on fruit and leaves. Treat with a copper-based fungicide to control the spread and keep the tree healthy.
  • Powdery Mildew: You’ll notice a dusty, white coating on the leaves. To fix this, improve airflow around the tree and, if needed, treat with a fungicide to clear it up.

Harvesting Avocados

  • When: The key to picking an avocado is maturity. The fruit should feel firm, but not too hard, and have a slightly darker skin color than when it was first developing.
  • How: To harvest, gently twist or cut the avocado from the tree, leaving a small piece of stem attached to the fruit. Avoid pulling too hard, as it can damage the tree or the fruit itself.
  • Ripening: Once harvested, avocados don’t ripen on the tree, so place them on your kitchen counter at room temperature. Within a few days, the skin will darken, and the fruit will soften, signaling it’s ready to eat. If you want to speed up the process, try placing the avocado in a brown paper bag with an apple or banana.
