Q: I received my avocado Wurtz tree yesterday. Per instructions I
have put the tree in a pot first. However I am having difficulty deciding
what to trim off. Yesterday I removed obvious damaged leaves. However as you
can see, the leaves are lighter in some areas and contain yellow and red in
some spots. What would you advise? Given this is a critical state as I do not
want to shock the tree after the trip, I would like to do everything possible
to protect it and ensure viability.
A: Your Avocado tree looks great and healthy overall. You've done excellent job planting it. Wurtz is a good, vigorous variety, while the tree is somewhat dwarf,
great for containers.
You are right, it is the best for the tree to leave it alone and do not
trim or remove leaves any more, until it starts showing new growth. Then it will
be obvious what needs to be trimmed. Reddish/orange color of young leaves is
normal. If any spots or dots - no need to remove those leaves yet. Wait
until the plant grows more leaves. It needs them for photosynthesis, in order to
become stronger.

Avocado is good for you. It's one of the Superfoods. Even cats know this fact.
Did you know that Avocado comes in hundreds of varieties, not just green and black?
Healthy Plants - Q&A from Mr Booster: Feeding Avocado Tree
Q:We bought one of your avocado grafts and it's doing great, lots
of buds for fruit. It's still in a pot and fertilizing with the Sunshine Boosters. Should we continue with this product? We'll plant
it in the ground in March. Thought you'd enjoy pictures of our wonderful
tree. No freezing temperatures in Riverview, but when it got down into the 30s,
the plant came in. One good thing about growing in the pot. I'll be buying
some more Sunshine Boosters. This stuff is working great on all our plants.
A: Congratulations with a good job on growing avocado over
winter. Avocado trees are not easy, we are happy to hear that your plant is ready
for production, this is amazing! We've noticed that Sunshine Boosters perform
miracles. Here are some suggestions for you:
1) Continue fertilizing with Sunshine Boosters according to the feeding chart
2) When ready to plant, dig a large hole and fill it with good soil full of
organic matter (compost mixed with existing sandy soil will be good). Make
sure to plant the tree on 3-4"high elevation, like on a little hill. Avocados
need perfect drainage and can't tolerate wet feet. See more info on planting and planting instructions (pdf).
3) Water daily with a hose, do not rely on sprinklers. Avocados like water
(considering perfect drainage)
4) Continue applications of Sunshine Boosters at least until the tree is established and starts
growing new branches with lots of leaves. After that, you can switch to
slow-release fertilizers once a month if it makes it easier, but if you can, continue
Sunshine Boosters at least on weekly basis - they really boost plant growth!

How to protect tropical plants in Winter
Winter tips and podcast

Winter can be tough on plants, especially on tropical varieties. But with a little preparation, you can protect your garden and keep your plants safe from the cold. Here's how:
Winter Care Tips for Tropical Plants
Cut watering: Reduce watering to prevent root rot. Cold + wet = dead roots.
Water before frost: Thirsty plants are more vulnerable. Water them before a cold night to prevent damage.
Wind protection: Wind is more harmful than temperature drops. Plant near structures like houses or trees for shelter.
Prepare for long cold periods: If cold weather lasts for hours, use all available protection, including Christmas lights and propane heaters.
Don't use dry fertilizer in winter: Heavy fertilizing encourages tender growth, which is more susceptible to cold damage. Sunshine Boosters liquid fertilizers are safe to use year around as their intake is controlled by reduced watering. Use fabric covers, not plastic: Plastic can cook plants in the sun, while fabric allows better ventilation.
Photo above: we cover our plants in the nursery with a thin synthetic fabric (sintepon) called "frost cloth" or "strawberry cloth". It is light, breathable and allows light and water to go through unlike plastic that creates heavy water pockets.
Prepare for Cold Nights
Wrap plants: On cold nights, cover individual plants or trees with sheets or blankets to shield them from wind chill.
Use Christmas lights: A simple string of lights can add extra warmth, protecting your plants during frosty nights.
Use propane heaters: For added warmth in a larger area, place a propane heater near your plants. Make sure to follow safety guidelines and keep the heater at a safe distance from flammable materials. This can help maintain a few extra degrees of warmth, especially in more open garden spaces or temporary greenhouses. Always ensure proper ventilation to avoid harmful gas buildup.

Large Collections? Build a Temporary Greenhouse
Affordable winter greenhouse: For large plant collections, you don't need an expensive greenhouse. A mobile carport with plastic or fabric covering, costing around $200, can house up to 100 plants!
Photo above: Temporary wrapping around plant collection with a plastic or frost cloth protects from a windchill. It may also win you a few degrees even without a heater. In this particular case, according to our temp sensors, with 30F outside, it was 41F inside this "dome", no heaters used.
Southern Exposure and Garage Storage
Southern windowsills: Compact tropicals can thrive on southern-facing windowsills, getting plenty of sunlight during the day.
Move plants inside: If you have larger collections, move them into a well-lit garage for the colder nights or longer periods.

Key Factors for Survival
Cold duration: Tropical plants can survive brief cold spells but long durations, even above freezing, can be deadly.
Wind-chill: Wind chill can be harsher than the temperature itself.
Exposure: Southern-facing slopes hold heat longer, making them ideal for your plants.
Humidity: Proximity to lakes or oceans can create a milder micro-climate.
Gradual temperature Drops are safer. Plants adjust better to slow temperature changes than sudden cold blasts. Gradual cooling allows plants to prepare, reducing the risk of damage.
Strengthen Plant Hardiness
Health and maturity: Well-established, healthy plants are more cold-hardy. Boost plant immunity: Use products like SUNSHINE-Epi to improve cold resistance. Apply it before and during cold snaps to protect your plants. Healthy plant is hardy. Make sure to fertilize your plants on regular basis - healthier and stronger plants are more cold hardy.
With these steps, you can protect your plants and help them survive the winter months. Stay
warm and keep your garden thriving!
