Winter is coming tips

Reminder from Kristi, the Tropical Flower Girl

As the weather gets cooler, many of you move your potted tropical plants indoors. Please remember:
1. Leaf drop. Lower air humidity, lower light and short day may cause some leaf drop. This is normal for seasonal environment change.
2. Reduce watering as it gets cooler and darker. Under lower light and in cooler temperature, plants won't need much water; some plants go dormant and only need minimum water (so soil doesn't completely dry out). Excess water may damage roots and kill a plant in winter.
3. No dry fertilizer in winter. Active growth stops. Let the plant to go into dormancy or simply have a rest. You can continue liquid Sunshine Boosters according to regular dosage chart with every watering. Since the watering is reduced, the plants will get only as much food as needed for getting through the winter.
4. Watch for insects by inspecting leaves regularly. They may attack plants more likely in the indoor conditions. You may use organic NoBug insecticide especially for your indoor plants.

Tahitian Gardenia

Q: I am interested in your Tahitian Gardenia and I would love to try and grow this plant in a large container/fabric pot. The soil here where I live is terrible as it's hard rock, clay, and sand! So I'm not sure if amending the soil would help to plant in the ground? Can you tell me if this will do okay in a container or best in ground? I live here in Las Vegas, NV (zone 9a). Any information would be great to help me make a this decision, I love the selection of cool tropical plants you offer! Also my daughter does Tahitian/Polynesian dance and this would be a cool "topping on the cake" if she could have a live Tiare flower in her performances.

A: Tahitian Gardenia will be doing best if grown in container in your area. In its natural habitat, it grows full sun but also it enjoys mild weather conditions and high air humidity. All gardenias prefer acidic soils. In your area, if planted in the ground, it may be exposed to some harsh conditions: too high temperatures, too hot sun, dry air, and as you mentioned - heavy clay and sandy soil. You can enjoy this plant grown in container, which can be moved as needed away from too much sun during summer months. Use well-drained potting mix. Use plastic pot, do not use fabric or clay pots - soil will dry out too quickly.
Also remember to fertilize this plant on regular basis with a liquid fertilizer SUNSHINE Pikake - Fragrant Flower Booster.
Grow gardenia in full sun or semi-shade during the hottest months. You may spray it with pure water if the air too dry and hot. Enjoy your Tropical Beauty and good luck!

Mango leaves and fertilizing

Q: I received a mango tree we ordered last week (I am in California) and am trying to make sure we take care of it properly. I noticed the corners of some leaves have began drying out. I wanted to see if there was anything else we should be doing or if it is something normal. Overall the tree looks good and the leaves have perked up, but I noticed the dry tips on a handful of leaves. Any help is appreciated! I have not fertilized in the pot yet or applied the mango sunshine booster.

A:Your mango tree looks pretty healthy, and these dry leaf tips may be caused by overall shipping stress. You have dry air in California, and temperatures may be getting up, this may cause additional drying effect. You may start fertilizing with a liquid fertilizer, it will help the plant to get stronger and grow faster - then heat and dry air won't be a problem as soon as the plant becomes better established and hopefully go into a bigger pot soon, or in the ground. Make sure to provide regular water if you have hot dry summers.

Establishing Mamey Sapote

Q: I purchased Mamey sapote last fall and am very excited about having it in my yard. It lost leaves during the winter, but then budded and put on a lot of beautiful leaves. I was hand watering since this covid stay at home event, and thought I'd put it in a larger container, 10 gallon. About 2 months after transplant and hand watering the leaves turned yellow. I cut back on watering, allowing some dryness between. Some leaves now have fallen off, but looks like new ones forming. What have I done and most importantly now, what do I need to do so she survives? I haven't yet decided exactly where to plant her... so hoping she can stay in container for a bit longer while recovering.

A: It is possibly a combination of over-watering and seasonal changes (re-leaf). During this time of the year, Pouteria sapote loses old leaves and grows new ones. This plant is semi-deciduous, which means, it drops leaves during unfavorable conditions (too dry, too wet, too cold, to hot, etc. = any stress). The new buds are healthy. Give it a couple of weeks. Reduce watering. Don't water again if the soil is still moist. If planted in the ground, it will be easier to control the moisture, as long as you plant it high enough (at least 3-4"above the surrounding area, like on a little hill, for a better drainage. See how to plant a tree.
Once you notice a new growth and healthy leaves, give the plant some food:

How not to kill gardenias?

Q: I have tried to grow gardenia in pots for years and never keep them alive. When i look on camellia websites they say fertilize potted plants twice a year. I'm confused as I tend to kill them with kindness haha. Also, if our tap water has high cal/mag and that stops the gardenia getting other nutrients why would I make up the feed with tap water? So confusing and online is mixed messages...

A: Gardenias are not the easiest plants to grow, however, they are easier in pots than in the ground: they prefer acidic soils, and in many areas soils are alkaline. The most important factor is balanced and sufficient nutrients. In the ground, plants have no limits to reach out to different elements by spreading their root system. In a pot, once all the good stuff is consumed, plants start suffering nutrient deficiency. This is why a balanced feeding program is important.

Generally speaking, Cal/Mag in tap water cannot be bad, because they are essential elements, good for plants (in proper amounts). However, just Cal/Mag is not enough. This is why you need a balanced liquid fertilizer for plants that prefer acidic soil. Excessive Cal/Mag alone can create nutrient lock up, especially if they are chelated with EDTA like in dry fertilizers, which are not fully accessible for plants.
We recommend natural, Amino-Acid based fertilizers that are completely consumed by a plant and are safe to use with EVERY watering, even in Winter. They are scientifically formulated and cover all plant needs. For your gardenias, you should use SUNSHINE Pikake - Fragrant Flower Booster.
Another important factor is proper watering. Gardenias like regular water but don't like wet feet = well drained potting mix is a must, similar to Abundance professional growing mix.
