I have had this plant for 2-3 years now and recently (about 2 months ago) I started noticing some problems on the leaves such as dry spots, bumps and brown near the edges and base. What can I do about this? I water the plant about once every 5-8 days, it gets plenty of light (as you can see from the pics). I have never fertilized the plant and I also dust it off about every 2 weeks. enter image description hereenter image description here enter image description here enter image description here

  • Brown tips is usually a sign of too much water. Try to water it when the top layer of soil feels dry (finger deep). Some fertilizer might also be a good idea, especially during the spring/summer periods. – benn Aug 28 '18 at 15:59

I think your yucca plant looks fine, for a houseplant. If you have such a plant for 2-3 years in your home, it will look more or less like yours.

I cannot see exactly what you mean with the bumps and brown spots. The brown at the base (stem) is normal, it is because the stem under it is brown. You can tear off some of the lower leaves (pull down at the stem), the plant will look better then (because the lower leaves droop/hang very much). But best time to do this is spring though, just before growing season starts (now it is a bit late in growing season and it is coming to an end soon).

You say that you never fertilize it, well that might be one cause of a bit yellowing leaves. I give my Yuccas some liquid fertilizer (Pokon) every 2-3- weeks during the spring and summer. Furthermore, the plant will be happy when you repot it every 2-3 years, in a slightly larger container with fresh potting soil. Also you water it quite often, it would be better to water it every two weeks or so, and wait until the upper part of the soil is dry (half finger deep). Brown tips of the leaves are often a sign of too much water (but you have no picture of that).

  • Ok, I see. By the spots and bumps I meant whats happening on the last picture. those small yellow spots are elevated, is that normal? – Mihkel Aug 29 '18 at 16:28
  • Those spots look like scar tissue from mechanical damage. Maybe by dusting it off, is it on the new or old leaves? – benn Aug 29 '18 at 16:34
  • Those are on some relativily old leaves, at the middle of the plant. I can assure you its not mechanical damage. – Mihkel Aug 30 '18 at 13:18
