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.

How to get shade quickly... and stay away from oaks

Q: I just moved from Tennessee into a new house in Florida and there are no trees on the property, the yard is brutal hot. What can I plant so I have some shade real quick? I like Florida shady oaks, how long will they take to grow?

A: First of all, do not rush into oak solution. Oaks are beautiful shade trees, however they have at least 2 problems:
a) Oaks are slow growers and unless you are willing to wait some 20 years... you won't get that desirable shade that quickly.
b) We have hurricanes in Florida... sometimes. A hurricane can damage any tree, however with oaks it may be the worse case scenario - the branches of those giant trees are huge, hard and heavy and in unfortunate situation when you need to remove or trim a broken tree, it may cost you... a few thousand dollars.

These are solutions that are more economical and practical:

1) Selection. If you have room, get one of these most popular Florida shade trees: Royal Poinciana, Golden Shower, Hong Kong Orchid Tree, Red Kapok, Bottlebrush, and many others. See full list of fast growing shade trees. Or simply get a Mango Tree and have delicious fruit too! Many varieties of Mangos are very large and fast growing.

2) Do it right. Even if you are planting a smaller tree, 1-3 gal size, it may become a nice shade tree within 2-3 years and start providing your driveway with desirable shade. The keys for fast growth are -
a) Good soil. Dig as big hole as possible and fill it with good rich soil containing compost. See planting instructions PDF.
b) Water. Do not rely on sprinklers and rains. Water your tree daily for the first week, then at least twice a week for another month. After that, irrigation system will be enough.
c) Fertilizer. Put a few handfuls of fertilizer in a planting hole. Then fertilize once a month during warm season. Apply micro elements for even better results and faster growth.

3) Ask experts. Contact our office for advice. We will suggest the most suitable shade tree for your yard based on features of your property: location, soil, exposure, etc.

Full Sun Garden vs Shade Garden

"Someone is sitting in the shade today because someone planted a tree a long time ago." (Warren Buffett)

Q: I live in California and I have a large area of my garden in full shade. Are there any plants that will be happy there? I am looking for something colorful. I also have a smaller area in front of the house that has full sun almost all day long, but I am afraid this can be too hot for flowering plants? Can you recommend something?

A: Full sun gardens have a strong, bright look while shade gardens have cooler, subdued appearance. Both types of gardens are fun to design and maintain as long as you pick the right plants.
Full Sun Garden is the easiest to grow. Depending on exposure, it may require some plants that can tolerate the hottest summer days and the dry conditions in your area. The good news is, the majority of tropical and subtropical plants prefer full sun, so you have a large selection to pick from - fruit trees, flowering trees, shrubs, vines, and small perennials. The more sun, the more flowers and fruit you will get! However, keep in mind that sun gardens require more water, but generous mulching will help to minimize watering.
Shade Garden is much more restful in appearance, but sometimes may be a little more difficult to work with. As shade trees grow bigger and thicker, it may become too dark; nothing will grow in total darkness. In this case you need to prune back some branches to let more light in. Filtered sunlight or dappled light coming through the leaves of the trees is beneficial and considered light shade, which would be the best light conditions for shade loving plants to thrive. Although shady cooler spaces attract more insects and will require more attention to control them, they also have some advantages over sun gardens. You can enjoy working in cooler conditions, and your garden will require less water. Many foliage plants look more deeply colored and healthier than in full sun; white flowers shine instead of looking washed out!
Our favorite shade plants are fragrant brunfelsias , clerodendrums, and of course colorful gingers and heliconias. You may also consider ornamental foliage of Calatheas, lush Alocasias, Colocasias, and colorful Cordylines. Check out our shade loving plant list for more colorful suggestions. These are also great for indoor gardens!

Quick shade for your driveway

Q: Please help! We just moved into a new house in Florida and don't have any mature trees yet, but the sun is already brutal! Can you suggest any super-fast growing shade tree that can make shade over my driveway as soon as possible?

A: Check out Giant Potato Tree - it is very fast growing, has very large leaves plus very pretty purple flowers as a bonus year round! The pictured tree was planted from 3 gal only 6 months ago, and already covers with shade the whole car. It is small to a medium size tree, but one of the fastest growing. If you are looking for a larger tree and willing to be more patient, here is the full list of tropical and subtropical fast growing shade trees. Most of them may take a few years until they reach a mature size, however, in order to enjoy your shade tomorrow, you must plant the tree today!

Clay or plastic?

Q: I purchased an Avocado tree and planted it in a nice clay pot that I bought in a special pottery place. My tree looked very healthy when arrived but after a week leaves become droopy and started yellowing. I was advised this was a sign of over-watering. I watered the tree only once since I got it 2 weeks ago. What is wrong with my plant?

A: Unfortunately, the fancy pot may be the reason. Although clay pots (plain clay, without glaze) are considered to be good for root health, however, the root system is hard to control and difficult to check without disturbing. Clay pots with fancy glaze and painting may have a drainage problem. We have noticed that cone-shaped pots are usually problematic for drainage, and a plant always has "wet feet". Avocados like watering, but cannot tolerate sitting in water. If you want to avoid root problems and still like to keep a beautiful look of your treasure plant, you may use a fancy planter, where you can put your plant growing in a plain plastic black nursery pot of much smaller size than a planter: its vertical walls are perfect for drainage, and the pot is easy to remove for re-potting or inspecting. Make sure to put a layer of drainage rock on the bottom of the planter so your efforts won't be in vain.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:
1) Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4) Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?

A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.

1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.

2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.

3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.

4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.

5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Seeds germination in summer

Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?

A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:

- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.

- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.

- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4" diameter).

- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.

- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.

- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.

- Do not overwater young seedlings, keep soil slightly moist but not soggy.

Our honest advise on Holiday Gift Plants

Q: Any suggestions on gift plants? With Holidays around the corner, I've been thinking of getting a present for my grandma, she lives in FL and is an experienced gardener. I also have a friend that lives in CA, also warm climate, but she doesn't have a green thumb. Any "easy" plants I can try for her?

A: Live plant is a perfect gift, as we all know. However when ordering a plant online as a present, for a happy experience, you should have three things to consider:
1) Gardener's experience. Planting instructions are included with every order, and usually success is there if you follow them. But all plants go through shipping stress (some more, others less) and need time, patience and love to recover. Also, a plant will need a new home after shipping: a pot and a good soil mix. It would be wise if you add potting mix with a gift order; the plant should be planted in a permanent pot as soon as possible, but normally can wait a day in a packing bag until its new owner gets a pot, if it is not ready yet.
2) How easy the plant is? If buying a plant for a beginner, chose something easy, as well as showy. Adeniums - Desert Roses, Jasmines, Clerodendrums, Cordylines are always a good choice. Calatheas, Gingers and Heliconias are always showy, even when not in bloom. Spice trees and herbs are fun, easy to grow and one can enjoy their aroma right away without waiting on them growing bigger. Miracle Fruit is an awesome present, it comes with detailed instructions how to grow the Miracle!
3) How easy the plant ships? Some plants can be easy in cultivation, but they don't take shipping well. After being in a dark box for a few days, most plants usually recover well in experienced hands. When making a present, you want something showy, not just a stick to arrive. Besides Adeniums and Jasmines, many fruit trees usually take shipping without a problem - such as Mango or Sapote trees. You may not want to start with Avocado, Papaya, Carambola, or Cacao - unless they go to an experienced grower - these may take some time and skill to etanblish. Fig trees are super easy in shipping, but figs may drop leaves in Winter - for this same reason, you may think twice about deciduous plants like Sugar Apples, Grapes, Mulberries or Persimmons to be sent as gifts. On the other hand, if you are sending a deciduous tree to a gardener who can appreciate the variety, this may be a good choice - dormant plants take shipping with less stress!
