    Not really recommended. It can clog pores and attracts dust. Depending on the variety, truly clean plant leaves have a natural sheen of their own. If you really really want to shine leaves up, wipe with a 1:1 milk:water solution. Not as bad as mayo but not as good as natural leaves!

      Yay! That's great! I'm glad you didn't give up on your plant.


      Jobe's sticks are probably fine but they aren't my favorite. The *potential* problem is that while the sticks dissolve in the soil slowly, IF a stick happens to be inserted too close to a main root (and that can happen even following the directions on the package), that root can get a fertilizer burn.


      I prefer fertilizers that are dissolved in water. My favorite used to be sold under the brand-name "Peter's" but it's now sold as "Jack's" at least in my part of the country. (Could be a regional thing.) It's a blue powder you mix with water. It comes in a red, blue, and white tub that looks like a soft margarine tub and it goes a really long way. There are different formulas but for non-blooming houseplants, the general 20-20-20 formula is best. If you mix it at quarter-strength, you can use it every time you water **while plants are actively growing**. In the northern hemisphere that means March-Sept. The only houseplant I'd not use that for is a fern. Ferns tend to do best with a fertilizer called "fish emulsion." (But look out if you have cats. It IS made from fish!). Even if you don't use Peter's/Jack's I'd use a liquid. Miracle-Gri makes one that's good, for example.


      All that said, I'd not fertilize your mayo-damaged but alive- and-coming-back plant just yet. Yes, plants need nutrients to grow just as humans do. But just as when a human has been very sick, giving food to a plant that's been sick isn't a good idea. It's kind of like giving someone who just came out of a coma in ICU a big juicy burger and fries. The person's body can't digest the food or absorb nutrients at that point. And your plant is sort of in the same situation. Wait until summer, don't over-water in the meantime (given that there aren't many leaves) and then fertilize lightly until fall. And cheer the patient's recovery!


  • Yes, I've read in several places that it works and is safe.

    just spray it off in shower with warm water; the leaves need to breathe to complete the process of photosynthesis vital to plant growth,health and survival. PROCESS-The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata.

    This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.The photosynthesis reaction makes glucose and the respiration reaction break it down. In photosynthesis, the energy which goes into the reaction is light energy. In respiration, the energy which comes out is chemical energy.
