When the cycads give new leaves on the young plants, normally this time of the year in South Africa, do I need to cut all the old leaves off? My wife does this because she feels the stem will grow faster, but I feel the old leaves need to protect the new leaves.
You are correct that the plant still needs the old leaves. Old leaves that are still green are providing energy for the plant and helping it grow, and the plant will be healthiest if the old leaves are left on. The new leaves of cycads sometimes appear to grow very slowly, but this is normal and not a concern.
Any leaves that are completely dead and brown can be cut off.
I have two plants, one I've had a few years and the other a few months. My problem is with the new one. It has something growing on it. They range in color from almost clear to black lumps on the needles. The lighter the color the smaller the lump. I haven't found any on the older plant.
This appears to be a Scale infestation.

I have long fronds growing out of the center of my cycad. They don't look like leaves and are now turning brown and curling on the ends. In reading about the other palm plants on your site, I see that the palms on the patio have very similar looking shoots growing out the center. What are these and do I leave them alone?
It sounds like you are describing a flowering event on your plant.

I have a cycad palm. I purchased it and found it had bugs. Treated that, but in the meantime, the palms started to turn yellow and fall off. I still have the bottom part of the plant. Can I get that to grow and, if so, how? I have kept watering it in the hopes of it coming back.
If the base is firm, it is likely still alive and could recover.
Reduce the watering and only water when the the soil is dry.

We have a lovely cycad growing in a raised bed on our front lawn, and this year it has 3 large shoots attached to the main trunk, plus it has just had a massive creamy coloured flower in the centre, and now coming out of that is 22 new very healthy fronds, and the old ones are starting to go yellow. Can I remove the shoots and place them in pots with potting mix for transplanting? And would it be ok to remove the old fronds, as this would make the plant look so much nicer? I await you reply. Regards, Malcolm.
Sounds like you have 3 pups, and yes you can remove them and propagate them.

Can you help us? Our cycad has gone yellow. Thank you.
Yellowing in any plant can be a sign of a few problems, including too much or too little water. If the cycad has just turned yellow without any change in environment, the most likely cause is nutrient deficiency.

Good Afternoon, My name is Charles, I'm an experienced gardener from New Orleans. I've collected rare and exotic tropicals for years, but recently my horticulture buddy got me hooked on Cycads. Over the last couple months I've done plenty of research on how to culture Cycads, but for some species I've had a tough time finding information. I'm still unsure how much of the caudex I should bury for some? I guess my second question is: do arid species vs more tropical species prefer their caudex at different depths? I have a Cycad Mitcholitzii and a Z Fischeri which I believe like to stay fairly moist, and three Z Pygmaea which like to dry out(trying to find info on them is a nightmare). Also, the pygmaeas are seedlings, not sure if that is a factor. I would greatly appreciate any advise Thank you, Charles
