Click on links below to jump to that question.
We have three beautiful Norfolk Island pine trees (in large pots) that thrive outside. We keep them in a greenhouse climate during the winter on the south side of our home. This year, the greenhouse took a hit from a winter storm and exposed the plants inside to temperatures around 19 degrees. Obviously, they took a serious hit and have browned out at the top, to about 8″ above the soil. Are they DEAD, or will they possibly come back this spring? If they will come back, what pruning tips can you give me?
If part of the tree is still alive, it can survive but, unfortunately, it will be deformed. Once the main trunk is killed at the top, several side branches will take over to become trunks. Even if only one branch steps forward, the tree will be oddly shaped. Pruning itself will not harm the trees, but they will not regain their former shape.
One of the branches of my Norfolk pine is broken. Not all the way, as the needles at the end are still growing, but it isn’t straight like the other branches and can’t hold itself up. How do I repair it or strengthen it so that it still gets nutrients to the end of the branch? The tree lives inside all of the time.
If it's broken along the branch, you could use bamboo kebob skewers or popsicle sticks as splints, and string or yarn to wrap the branch so that the broken pieces are held together; in time, new tissue should grow. If the branch is broken at the trunk, use string or yarn tied from the broken branch to the trunk or the branch above, so that the broken part is held up to where it's supposed to be, then wrap branch and trunk with tape, any kind, doesn't matter. Once again, new tissue should grow.
Obtained 26 seeds from eBay. Good quality seeds. Planted some in moistened potting soil, some in vermiculite, and the rest in a 50/50 mix of potting soil and vermiculite. I keep them covered, mist the surface lightly every day, 70 plus degree environment, good natural light location. 16 days have gone by and there are no sprouting signs yet. Can you give me some additional advice and encouragement? Any good reference books?
Should the bottom fronds of a Sago Palm be cut off each year? My Norfolk Island Pine is losing its fronds and has stopped growing. We have had it eight years and was getting top heavy in the small pot so we repotted it a few months ago. I read on one website that it was probably in shock or needed misting. I have been doing that. It is near an east window so gets only morning sun. Can it be saved?
No, you do not need to prune sago palms. They actually do better without being pruned. It likely is shock. A little fertilizer that is high in phosphorous and consistent watering will help, but other than that, it just needs time. Many plants will recover just fine from shock so I would not lose hope for it.
Cutting one or two exposed tree roots is not recommended as a control method, except as a last resort. There are some other things you might try first, as in this article: https://www.gardeningknowhow.com/ornamental/trees/tgen/exposed-tree-roots.htm
Seed pods, yes. Your tree is a female, and there would be a male close enough for pollination, so every few years you can expect seeds. A shop vac is a handy tool for picking up the sharp little seed pods.
