Doubts with my cymbidium - Orchid Board

Orquiadicto · #1 03-31-2012, 08:15 AM

I just saw this "cone" on one of my cyms. It looks different from the other new growths so I keep saying to myself it could be a spike. Do you think it could be a spike? It is much thicker than the rest of the growths when they started-
One other question is, why are the tips on some leafs browning? Too much fertilizer, too much water, too much sun, or too little of all?
please help me.

I'm curious about the leaf tips too. I have no experience with cyms and this is a constant issue on mine as well! Congrats on the possible spike! I'm jealous. Never been able to get mine to spike, only kill the plants, lol...

Are the browning leaf tips from leaves that are old?

You may have a flower spike coming along, just as you presumed.

The browning leaftips are indeed from "old" leaves. At least, not from the pseudobulbs that haven't bloomed yet.

It may be natural. Old leaves on Cymbidiums die back.

I know a phrag's leaf tips will brown/burn with to much fertilizer. Cymbidiums like to be feed but as with anything, you can have to much.

Looks a bit like nitrate burn to me also underwatering creates dieback.

This is usually seen when a grower has gone too long a period between watering and then used too high a strength fertilizer on a dry media.

Now winter seems to be definitively come to an end, I have my cymbidiums outside in the garden together with all my other orchids (except the blooming ones). The other day there was some heavy rain during the night and day. Do you think this rain might have affected them? It seems as if the pseudo bulbs on one of the cymbidiums is going yellow and also a leaf on my odontoglossum. I put them inside again a few days till chances of rain were over and now they're back again outside. I hope they will thrive.

I'm afraid what I thought might be a spike turned out to be a new growth. Of course that is something good as well because it means the plant is healthy and it is growing and spikes do come from new growths, don't they. So the more growths, the more possible new spikes. Anyway, I saw these two other "things" (pictures 2 and 3) that defintely look different from the new pseudobulbs. Please, confirm my wish and tell me they are spikes forming.
On another cymbidium I saw this (last two pictures). Do you think this could be a spike? I never had new spikes on any of my cymbidiums before, so I'm realy excited about the possibility it could be a spike.
