Happy Hobby: growing tropicals from seeds

Q: What is the best time to start tropical plants from seeds? Should I wait till spring?

A: If you want to feel happier, get into gardening. If you want to feel God, start plants from seeds and watch New Life grow from a tiny grain. Fall is a perfect time to start tropicals from seed.
Traditionally, people prefer sowing seeds in Spring, especially temperate species for a vegetable garden: tomatoes, peppers, cucumbers... My grandmother up North started them in early Spring in paper cups on a windowsill, then once the temperatures went just above freezing, she planted them out in the garden beds, and that early start always helped her to have the best early crop in the neighborhood.
When we deal with tropical plants, "just above freezing" is not warm enough. Which means you have to grow small babies indoors for quite a while, providing additional heating when needed. Heating pads always work best. If you keep your living space around 75F (ideal for many species), this is a perfect temperature to get your seeds started. Tropical plants are not like annual tomatoes that try to grow through the season as fast as possible. They take time. So the sooner you start, the more chances to get small seedlings just in time when Spring air outside is "warm enough" for those tropicals - at least in 70's.
A great advantage of starting tropical seeds indoors is controlled temperature and moisture. In the plant world, environment extremes are not good for the germination process. Mild conditions of your home or a greenhouse create better chances for successful growth. Seeds won't get overheated in the hot Summer sun, and won't rot because of a sudden heavy rain. Just keep in mind that some species require light for good germination.
For the best seed germination:
- Use only well-drained mix - we recommend special Seed Germination Mix #3, professional grade. Put seeds not too deep (1/2 inch deep or less) to allow air circulation
- Soak large seeds for a few hours with Sunshine-S solution
- Keep warm (75-85F) and in bright light
- Keep soil slightly moist but not soggy
- Apply micro-element booster SuperFood to baby seedlings for vigorous growth

How to get Passion Vine to flower?
From Mark Hooten, the Garden Whiz

Q: Several months ago, I purchased a passionflower vine, a red one with lots of flowers. I ended up putting it in a much larger pot with a large trellis, using a popularly advertised bagged potting soil recommended at a big box store. I have given it a blue colored water-soluble fertilizer every couple of weeks as recommended. However, while the vine seems very happy, growing faster than i can keep winding it around the trellis, it has not flowered all summer. I there something I am doing wrong?

A: Passionvines as a group (and there are some 500 different kinds!) are sort-of unusual among popularly grown ornamentals because they have "nitrogen issues". This is because, even though unrelated, they are much like most legumes, as they maintain a symbiotic relationship with certain beneficial soil bacteria which allows them to gather atmospheric nitrogen and store it in their roots. When they have an overabundance of nitrogen, they simply stop flowering and produce rampant leafy growth while never flowering. They only flower well after a period of healthy vine growth, because the plant had finally used up all of its stored nitrogen.
Since you had both used a bagged potting soil which likely already contained fertilizer with nitrogen added, as well as bi-monthly doses of a liquid fertilizer which also contains nitrogen, it has been receiving so much nitrogen it only knows to grow more vineage until the nitrogen is used up. If and when that happens, it will again begin to flower. This rule applies of course not only to flowering but also to fruiting varieties of Passiflora: the more flowers, the more fruit you get!
So the answer is - for the time being, just stop giving it supplemental fertilizer and it will start flowering for you sooner than later!

From Anna Banana: Shipping and planting during hot weather

Q: I received email notification that my order was delayed due to hot weather. Why? And do I need to do anything special if I plant when it is hot?

A: When plants are shipped via FedEx Ground, it is hot in the truck! According to our FedEx area manager information, if outside temperature is 100 degrees, inside the truck it can be 130! We don't want to put your plants through that much stress. We monitor the weather at destination, and as soon as it cools down a little bit, your order will be shipped.

Planting during hot weather:
1. For a mail-ordered plant follow planting instructions and never plant it from the box directly into the ground. Keep it in a pot the size of a root ball until the plant recovers from shipping stress, re-grows root system and adjusts from several days of darkness to a bright light. Move the pot gradually into brighter light, eventually into a spot of its permanent home. Do not over water the pot. Once you see new growth - the plant is ready to be transplanted into the ground.
2. Use only quality soil, containing lots of organic matter (compost, peat moss); soil conditioner is beneficial (pine bark). Plant it on a little hill, so growing point is elevated 1-1.5"above the rest of the surface.
3. Put a good layer of mulch around the plant, at least 1-2" thick, and not too close to the trunk as it may cause stem rot on contact.
4. Water daily with a garden hose until the plant shows active growth - then watering may be reduced every other day or less, or you may rely on sprinklers and/or rains.
5. If the sun is too hot, use shade cloth (or simply a white bed sheet) to cover the plant for the first few days (use bamboo sticks for support). It will help the plant to establish without heat stress. If leaves start dropping - this may be a sign of excessive light and heat. Shading is the way to reduce it.
6. Use SUNSHINE booster to help plants overcome heat stress, and shipping stress. It really works!

Remember that a plant has a very slow nature, unlike creatures from animal world. Give it some time and never rush it into new conditions. Go slowly and patiently - this is the only way to get a reward of a fruit crop or a beautiful flower.

Shipping plants during hot weather. Any temperature limitations?

Q: I want to order a plant that you have only one left in stock; however the weather is extremely hot in my area right now. Do you have any temperature limitations when you ship your plants?

A: We ship plants year around and do our best to watch weather forecast at destination. However the forecast may change to worse within a day or two while a plant is in transit. To ensure your plants have a safe trip during extreme weather, follow these steps:
- notify us if you want to wait until weather permitting so we hold your shipment until further notice;
- make sure to track your package and be at home at time of delivery. The only time when a plant can get temperature damage, from our experience, is when the box is left on your doorstep while too hot (or too cold) outside.
- you may use your business as shipping address if no one is home during regular business hours of delivery.
- unpack the box immediately and follow planting instructions. Keep plant in shade until recovered; never plant directly from a box into the ground; never plant into hot, full sun: protect a new plant with a shade cloth for a few days until established, and water as needed.
- use SUNSHINE booster to help plants recover from shipping stress. It really works! For only $4.95 with FREE shipping!

Care for ultra-tropical plants

Some tropical plants like Durian, Breadfruit, Cacao are rare in plant collections and require true tropical environment for successful growing and most likely greenhouse conditions unless you live in mild tropical climate like Hawaii. These plants are hard to find and are not cheap. They can be shipped to you in original containers via Express mail and usually take trip well as long as there are no delays or overheating (or cold) during transportation. To enjoy your rare plant collection gem, please make sure to follow these recommendations:
- Keep your eye on delivery, track the shipment and make sure package is not left outside in the heat or cold.
- Unpack immediately and put plant in humid, warm environment with filtered light. Remember, "warm" for tropical plant means 78-85F.
- If a plant is wilted, put clear plastic bag over leaves to increase humidity for a few days. Keep the branches covered with clear plastic, in shade only - to avoid overheating.
- Keep soil slightly moist and don't let dry out. These plants like water as well as good drainage.
- Keep plant in original container until recovers from shipping stress. If necessary, re-pot in 2-3 weeks in bigger pot with rich organic potting mix, containing a lot of peat moss, and perlite or bark for good drainage.
- Grow these plants in warm and mild conditions, in filtered light, high humidity, with no temperature extremes. Remember to keep these plants at temperatures above 50F at all times.
