Min. Temps. Too Low
for extended periods.Examples:
N.Europe, Central US
US E.Coast |
Higher Min. Temperatures
Examples:
Jubaea, Nannorhops, Trachycarpus, Sabal minor. |
If freeze is marginal:
1. Fertilize in the fall to lower freezing point.
2. Use modern chemistry to enhance plant cells.
3. Cover with a blanket or plastic.
4. Apply thick mulch layer.
Hard freeze or if you want to save leaves/stems:
1.Use heating wires and a cover.
2. (Bananas): Cut in half, build a cage, and
fill with leaves. |
Min. Temps. Too Low
and very shortExample:
Southern US |
Higher Min. Temperatures
Examples:
Sabal, Serenoa , Washingtonia, Butia, Phoenix.. |
If freeze is only a few hours:
1. Amend soil with sand.
2. Fertilize in the fall to lower freezing point.
3. Use modern chemistry to enhance plant cells.
4. Have a sprinkler running.
5. Cover with a blanket or plastic.
6. Apply thick mulch layer. |
| High Fall Temperatures. Example:
S. US | Dormant Stage by Winter | - Change fertilizer by mid summer to
potassium only.
- Harden Plant with:
1. a rootstimulator (Superthrive)
2. a bio-catalyst (Ecosane). |
Low Fall Temperatures or
Short, Low Summer HeatExample:
N. Europe, N.W. US,
Canada | Heat And Grows Slowly | Apply liquid fertilizer every 1-2 weeks
|
High Spring Temps.
With Spring Freezes.Example:
S. US | Prolonged Dormant Stage
in Spring | 1. Let your plant grow but
watch the weatherforecast and
do as above (Min.Temp.Low.).
2. Prolong dormancy with:
a. delay pruning
b. delay spring fertilizing
c. use only rootstimulators and bio-catalists.
d. leave artificial protection in place |
| Low Spring Temps. Example:
N. Europe
Without Spring Freezes. | Heat And Grows Slowly | In early spring:
1. Prune dead and old leaves.
2. use granular long-term fertilizer
2. use liquid fertilizer every 2 weeks
|
| Low Summer Temps. Example:
N. Europe, Canada | Heat And Grows Slowly
Ex:Sabal spp. | 1. use granular long-term fertilizer
2. use liquid fertilizer every 2 weeks
3. build a cold-frame: Plastic cover w/space above ground. |
| Winter Moisture Example:
N. Europe, US Pacific NW | Dry Dormant Season
Examples:
Phoenix spp., Brahea spp., Washingtonia spp., Chamaerops humilis sbspp. | build an impermeable canopy (other protection):
four stakes supporting a plastic.
