What Avocado is better - Type A or Type B?



Avocados are divided into two types based on how their flowers open - Type A and Type B. This has nothing to do with how the fruit looks, only with how the flowers work.

TYPE A:
The flowers open as female in the morning of the first day, then close. On the afternoon of the second day, they reopen as male.

The most popular type A avocado varieties:
Bernecker, Black Prince, Catalina, Choquette, Day, Donnie (Doni), Fantastic, Florida Hass (Haas), Lila (Opal), Loretta, Lula, Mexicola, Mexicola Grande, Red Russell, Reed, Russell, Simmonds, Ulala (Oh La La, Super Hass) , Waldin, Wurtz (Dual Type, A&B).

TYPE B:
The flowers open as female in the afternoon of the first day, then close. The next morning, they reopen as male.

The most popular type B avocado varieties:
Anise, Bacon, Beta, Booth 8, Brazos Belle (Wilma), Brogdon (Brogden), Buck, Ettinger, Fuerte, Hall, Hardee Red, Hialeah Red, Joey, Kampong (Sushi), Marcus Pumpkin, Maria Black, Miguel, Monroe, Nishikawa, Oro Negro, Pollock, Poncho (Pancho), Thomson Red, Tonnage, Winter Mexican, Wurtz (Dual Type, A&B), Yamagata.
  • 🟢 Each tree can make its own fruit (it’s self-fertile), but if you plant both types together, they will help each other make more fruit. The flowers of A and B types open at opposite times, so bees can carry pollen between them more easily. This means better pollination and a bigger harvest.
  • 🟢 For home gardeners, one tree is enough to get fruit, but having both A and B types nearby will give you a larger crop. If you grow avocados in pots, it’s a good idea to have at least one of each type.


✍️ In short:
One tree = some fruit
Two trees (A + B) = lots more fruit!

7 secrets of a Happy Avocado Tree

Q: I purchased an avocado tree from local garden centers three times but every time it dies on me. My neighbor has a nice tree in his yard and it grows beautifuly. I just purchased one online from you and I need to know what I was doing wrong? Are there any secrets how to make an Avocado tree happy? I have a big garden and several mango trees, but no luck with Avocado...

A: Avocado tree is famous for being such a pain to establish. But once it starts growing, it's growing! We will share a few simple tricks how to make it right.

1. Plant high and provide good drainage. Wet feet is number one reason for failing an avocado tree. It doesn't like wet soil and won't tolerate soggy conditions. Plant it in the highest spot of your yard and slightly on a "hill" (3-4"higher than the surrounding ground).
DO NOT plant Avocado tree in low spots or wet spots of your yard. Save those spots for Cannas or Black Sapote or even a Mango if you want a fruit tree there.
2. Use quality soil. Use only well-drained soil with high content of organic matter. You may add compost to existing sandy soil, or add some professional potting mix that contains pine bark and perlite. Remove rocks from the hole if you see any while digging. Dig a big hole and fill it with a good soil; compact the soil in the hole very well before setting the root ball. Reminder: plant the tree high!
3. Water regularly. After planting an Avocado tree in a nice high spot with a good drainage, start watering it... daily! Avocado likes water, although it doesn't like wet feet! Once you figure out this combination, you've got the recipe of success. Water by hand daily for the first week after planting, then twice a week for couple weeks, then once you notice new growth - you may rely on sprinklers, but keep watching the tree and don't let the soil over-dry. It must be slightly moist, but not soggy.
4. Fertilize. For such finicky tree, we suggest mild formulas of fertilizers. Dry fertilizers may burn roots, especially of a young tree. Even smart-release granulated fertilizers should be used very carefully. The best way to feed your young avocado tree - get a complete set of Sunshine Boosters Pro system. It has all necessary elements for all stages of plant development and never burns the roots. Sunshine Boosters Pro can be used with every watering - no need to guess how much and when. Besides, it is a natural fertilizer based on amino acids - exactly what you want to use on your fruit trees and other edibles!
5. Boost immune system of the tree. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of the tree and protect it from diseases. Epi makes plants (especially young plants) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
6. Do not prune until you see significant growth. The tree is small and can use as many leaves and branches as possible for photosynthesis and healthy metabolism. We suggest to avoid pruning for at least the first year. On the second year your tree most likely will be covered with flowers (assuming you followed fertilizer program). Let it go through the blooming stage and setting fruit; prune in Fall after fruiting is over.
7. Keep number of fruit to minimum for the first crop. Don't let the small tree exhaust itself. Keep just 2-3 fruit to develop. The next year, no need to control fruit quantity, the tree will develop as many as it can support.
P.S. If you got the tree from a mail-order, remember to establish it in a pot before planting in the ground; move gradually from shade to sun. Follow planting instructions.

Ten best fruit trees to grow in Florida and Southern landscapes

🏆 Ten best fruit trees to grow in Florida and Southern landscapes.
# 2: Avocado Tree.
  • Avocado (Persea americana) is a must-have in any tropical or subtropical garden, along with the mango. It’s a favorite fruit known for its health benefits and superfood status.
  • Cold Hardy: Some varieties can survive temperatures below 25F, making it more cold-tolerant than mango trees.
  • Beautiful and Productive: Aside from the fruit, it's a lovely ornamental tree.
  • Grafted Varieties for Quality Fruit: Many plant enthusiasts enjoy growing Avocado from seed. Keep in mind that only grafted trees guarantee quality fruit and production right away, while seedlings take 7-8 years.
  • Growing Secrets: The avocado tree can be a bit tricky to establish. The two main secrets to successful growth are:
  • a) Good drainage
    b) Regular watering
    Avocados don’t like to dry out, but they also can’t tolerate wet feet. To ensure proper drainage, plant the tree on a raised mound (4-6 inches) and keep the soil consistently moist.
  • Compact Varieties Available: There are several compact varieties ideal for container culture, small spaces, and patios. Dwarf "Condo" varieties like Wurtz and Fuerte are perfect for containers, while semi-dwarf options such as Russell, Lila, Mexicola, Poncho, and Yamagata also perform well in smaller gardens.

Hardy avocados

Q: I intend to gift three avocados, at least one type A and one type B, to a friend who lives in an area where the temperature never goes below 25F. The idea is to give them a ripening season as long as possible. Which combinations do you suggest, and which are the A and B?

A: When talking about "A" type and "B" type in Avocados, it is referring to the flowers. An avocado will produce both male and female flowers on the same plant. "A" type means that the flowers are female in the morning and male at afternoon. "B" type means that the flowers are male in the morning and female in the afternoon. If you plant to start a commercial growth, then it's important to create a proper mix of both types. However, in hot and humid climate a single tree produces flowers of both types, so it is not necessary to have both A- and B- types planted together in backyard. Even a single tree produces enough fruits for home gardener.

It is also important to know that while there are more cold hardy avocados, it refers to a full grown established tree. They will still need protection from the cold until they are bigger and more established. One can not expect a small tree, which was planted in June, to survive the first winter. It'll take few years until the tree is "harden" enough.

Wurtz Avocado: Fruits from May to Sept. Dwarf hybrid. It is very compact and slow growing, reaching only about 8-12 feet at maturity. Distinctive weeping growth habit. Suited for planters, containers, patios, greenhouse use. Great for dooryard or container growing. The tree can handle temperatures to 25(F) degrees. Production is good and it is a consistent bearer.

Day Avocado: Fruits July to Sept. Day avocado is green, smooth skin and is shaped like a club. The fruit is of very good quality and has a nice buttery consistency. The slender tree is relatively cold tolerant and produces July through September.

Fuerte Avocado: Fruits Nov to June. Relatively cold hardy variety. Green fruit, elongated,flavor excellent, buttery. Vigorous compact tree with decidedly alternate year bearing habit. Ripens November to June.

These three will provide you with fruit ripening during the whole warm season. For the most cold hardy avocado varieties, see this info sheet.

When Bigger means Better

Large  Avocado  trees  in  containers

Everybody loves shopping online nowadays, and plants are no exception. Buying plants by mail order is not uncommon anymore; it only takes one click, and luckily, there are many sources - from big shopping malls like Amazon to small backyard nurseries that sell their seedlings on eBay or Facebook - all delivered to your door. But plants are alive... So when doing your online plant shopping, you must ensure that you fully enjoy your experience and are happy with a healthy plant that a) doesn't die; b) recovers quickly; and c) starts growing fast, so you can see flowers and fruit as soon as possible.

The rule of thumb for shipping plants: bigger plants undergo shipping better, experience less stress, less leaf drop, and recover quicker than plants with smaller root systems. So when it comes to buying plants online, the bigger, the better. Unfortunately, many mail-order plant sources may sell you a tiny twig that has very few chances of surviving. Shipping is very expensive today, so shipping a bigger size plant may cost more than the plant itself.

Below is a piece of advice on how to make the best plant selection for your garden...

5 important rules on how to buy trees online

1. Find a source with bigger plants. Check reviews, ask friends for recommendations, inquire from the company about the size of their plants and how they pack their plants for shipping.
TopTropicals offers well-established, strong plants with developed root system, in container sizes 1, 3, 7, 15 gallon, directly from a tropical Florida growing farm. Our unique plant-packing techniques are state of the art!

2. Price not always reflects the size and quality of the plant
TopTropicals offers many deals, discounts and sales, while still providing the biggest and strongest plants grown in real tropical conditions.

3. Most fruit trees must be grafted to produce good fruit. Make sure you are not purchasing a seedling when it comes to Mango, Avocado, Peaches and some other trees with named varieties that don't come true to seed.
TopTropicals offers only grafted - Mango, Avocado and a large number of other tropical cultivars.

4. Pick up when possible from the nursery your ordered from, or get a delivery, instead of shipping the plants. A drive to the nursery will save you more time and money in the future, plus you can hand-pick the biggest and healthiest specimens.
TopTropicals is open 7 days a week for your convenience. Visit our Ft Myers Garden Center or Sebring Farm to select the biggest plants.

5. Take advantage of X-Large size plant material if you live outside the tropical zone and are trying to zone-push your tropical garden. Bigger plants will establish faster and have more chances to survive cold winters. Again, it will save you money in a long run (although bigger plants may be more expensive, but their survival rate is much higher when it comes to cold nights).
TopTropicals offers X-Large flowering and fruiting trees (7-15-25 gallons), and most of the varieties you see in our online store can be custom-ordered in big sizes. Delivery and installation available.
