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

TopTropicals

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!

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.

Triple Sec Mango

TopTropicals.com

By Onika Amell, tropical plant specialist

Q: I live in Mesa, Arizona. I am considering purchasing two of you Triple Sec Mango trees. Can you please give me some information on this variety and how to grow it successfully here in hot and arid Arizona, if at all?

A: Triple Sec Mango is a new name for the superior variety Seacrest. The aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy, mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you live in an area of Arizona with hardpan (extremely compacted desert soil) or caliche (layers of soil cemented by calcium carbonate) you will have to learn how to deal with such soil types. Amend the soil as needed.
The best time to plant is spring or fall to give your Mango a chance to get established before the really intense Summer heat starts. Alternatively, protect the tree with a shade cloth. Tender, new growth will not stand a chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young trees especially will also need winter protection when temperatures go near or below freezing. Always plant trees in a location where they will be protected from cold wind. Consider staking your newly planted Mango trees for the first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good quality mulch around your tree as it helps to trap moisture, keeping the ground and the roots beneath it cool. Keep mulch a couple of inches from the trunk of the tree. Avoid a location that gets full day sun. Morning sun, afternoon shade is ideal. Give regular watering until the tree is established. Once established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.

Horned Holly - a cool bonsai plant

By Onika Amell, tropical plant specialist

Q: I live in Chickasaw, Alabama. I am a beginner bonsai grower. I received a lovely little Horned Holly as a birthday present and I want to know if it is a suitable plant to bonsai?

A: The Ilex cornuta - Horned Holly, or Chinese Holly, is very popular as a bonsai species. It is loved for its very beautiful and distinctive rectangular foliage and for its small, white flowers which give way to large, red berries. The berries are larger than those of the European Holly. The leaves are rectangular and unusually shaped with three large spines at the apex. This bonsai will take both sun and shade, but semi-shade is preferred in midsummer. If indoors, give it plenty of bright light. When kept outdoors, your Horned Holly bonsai will need some frost protection and should be sheltered from strong or cold winds. It will need a fair amount of water and should not be allowed to completely dry out. Watering during the heat of summer is especially important, as well as in spring right before the fruit production, and should be reduced during winter. This species will also appreciate regular misting of the foliage. Repot this bonsai every 1 to 2 years in early spring, using bonsai soil - TopTropicals Adenium Soilless Mix. Fertilize the holly every two weeks throughout the growing season using either a balanced fertilizer diluted to half strength. We recommend for this purpose Tropical Greenhouse Plus - Plant Booster. Pruning should be done in early spring.
Horned Holly is also very popular as a hedge plant as it grows dense and compact. It will grow to between 3 and 5 feet tall and will spread to an equal distance, giving it a round, shrubby form. It is cold hardy! Zones 6 through 9. It will tolerate a wide variety of soils as long as it is well-drained. It likes sun or part shade. It is heat and drought tolerant once established, and are often used in xeriscaping. Its branches produce dark olive-green foliage that is often cut for indoor decorations during the holidays.

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.

Australia Planting 1 Billion Trees To Fight Climate Change

TopTropicals.com

Australia plans to plant 1 billion new trees to fight climate change, by the year 2050. That is a lot of trees and is the first real effort the country has made toward combating climate change. The only real problem is finding enough space to plant that many trees...
A billion trees is a billion trees, and even with a team of 30,000 people planting a tree per day for the next 31 years, the final tally would still only be 339,450,000 trees. Australia will need a tree army to get that many trees planted by 2050... Read the whole story...

How about planting just one tree today and save the World one step at a time?

Pretty in Pink... and Purple Prince for her!

TopTropicals.com

By Onika Amell, tropical plant specialist

Q: I have a bare spot in my front garden, behind a low wall, in part-sun. I'm hoping to find an evergreen, flowering ground cover that will cover it quickly. Any ideas on finding something with the ability to eventually also cascade over that wall? I live on Marco Island, Florida.

A: Barleria Repens - Small Bush Violet, is a tough, fast-growing evergreen that blooms from late spring to autumn. Of the many Barleria we see in the tropics, Pretty in Pink is one of the most striking! The name tells the whole story: pretty and pink. A lot of gardeners enjoy using them as a ground cover. They will quickly cover a large area - their stems root readily as the plant crawls along. They are easily propagated by lifting the rooted runners or using cuttings. They also reseed easily. Flowers are followed by seed pots that explode open when dry, dispersing 4 seeds at a time! But perhaps best liked by many gardeners, is their habit to cascade. It will be well suited for covering the bare area in your garden and spilling over that wall beautifully.
When used as a ground cover, remember to pinch out young shoots to encourage bushiness and prune the plant back hard after flowering to keep it neat.
Barleria repens will also adapt to different situations in a garden if you need them to. Although they usually form a rounded to spreading bushy shrub, 2 ft high by 3 ft wide, they will climb when you give them support. They are often allowed to lean into nearby trees and shrubs.
Hardy to 28F, Barleria repens is pest-free and fairly frost-tolerant. They love sun and part shade, as well as well-drained soil and plenty of organic material. Avoid planting it in deep shade as it will get leggy and reluctant to flower.
They will thrive when fed with a slow release fertilizer at intervals of 6-8 weeks, throughout the growing season.

There is another cultivar of this exact variety that has blue-purple flowers, it is called Purple Prince! It couples perfectly with Pretty in Pink! :)

Monster hybrids of Monstera: juvenile and mature

by Mark Hooten, the Garden Doc

Q: I am a rare plant collector and obtained a very interesing cultivar of Monstera from you that says it's a hybrid Monstera adansonii x obliqua. Is there a named hybrid? The leaves on this specimen that came in 1 gal pot are much larger than the plant I have grown in a 3 gal pot for a few years, under name of Monstera friedrichsthalii.

A: Due to their diversity, it is hard to find verified hybrids in the genus Monstera. M. friedrichsthalii is apparently an old Florida name for what is actually technically M. adansonii. The "primitive" juvenile growth is very different from the much larger more robust form that only occurs when it is allowed time to climb a tree, in which case the foliage becomes very different and much larger with many many more fenestrations (holes) of various sizes. If you visit our Garden Center, you can see the mature form climbing the oak tree in our Shade Garden in front of our office - we use this mature plant for propagation. If you take a cutting and don't let it attach to a bark/trunk and climb upwards, it will quickly revert to the wimpy juvenile form. Seems that even climbing a pole indoors, it never actually develops into the truly mature more complex adult stage. Some juvenile forms growing on a tree if given too much shade, do not develop into the larger mature form. Move it in more light and allow it to climb, and it will look very different, but still is the same plant under different conditions.
