    Default Fertilize while in spike confusion

    I would think this has been asked already but I haven't found it. I'm a bit confused with fertilzing when a plant is in spike. I've always watered on a regular basis with a weak solution. But I've read a couple of times about not using fertilizer with an orchid in spike since it may cause the bud to drop. When using a weak solution does it matter? I can't imagine that anyone with a huge collection of orhids could withhold fertilizer every time something is in spike. I have a Dendrochilum ready to bloom soon I hope. I also purchased 2 new orchids in bud. I've been able to flower a jewel orchid with how I've been doing things. I don't want to screw these ones up.

    You are quite right Nicki that it's not practical to withhold fertilizer when you have a large number of plants that bloom at different times. In my case i follow my fertilizing regime regardless of whether the plants are spiking, budding or blooming. As long as the solution is weak I don't have a problem with bud drop. Also I fertilize in the cooler part of the morning to minimize burning. My friend who owns a nursery with a few thousand plants, says in his case it's nigh impossible to to practise 'selective' fertilizing, but he agrees that a few plants with a more delicate bent might be sensitive to fertiser applied while in bud.

    Monopodal orchids like vandas and phalaenopsis grow continuously even when they're in bud and blooming. Naturally they need some nitrogen to grow. I read an article recently that said phals given nitrogen while in bloom will hold their blooms longer. On the other hand some other orchids have distinct growing periods and blooming periods. Some of those orchids can abort their buds and go into a growth cycle if given too much nitrogen. I think your approach is probably a good one because it will provide enough nitrogen to the monopodal orchids and probably not enough nitrogen to interfere with the bloom cycle of other orchids.

    I weakly feed and fertilise while in bloom with no advers affects, I'm doing an experiments at the moment where I have inherited a couple of Epidendrums that are in spike but the buds has not fully developed some of them are in really bad shape so i'm seeing if the fertilising will perk up the spikes and produce flowers...
