I get that sometimes. It's usually from a bug that is inside a stem. Look above where you find the waxy white substance and check out the tips of stems (usually old stems). Are there any that are open/hollow (the stem looks like a straw)? If so, cut a bit below it until you get to a place that the stem is no longer hollow. Take the piece you cut off and slice it open sideways and you will usually find a little insect (larvae stage or tiny winged stage). I remember Martha Stewart always said that when she pruned her hydrangeas, she put elmers glue on the cut tips to discourage borers......I have no idea if this works.

Pygmy dates have a natural white coating on their leaves called tomentum. It is very natural and normal for many palms. You could post a picture to make sure but its most likely fine.

Flattie, play nice..... he was just asking a question...not such a strange way to start a post. The silver dwarf is a Trachy species

I found this on https://www.gsa.gov/portal/content/113602 Removing Linoleum Adhesive From FloorsProcedure code:965001SSource:Ohj - Shirley Maxwell & James C. Massey, 9/30/92Division:FinishesSection:Resilient FlooringLast Modified:08/02/2016 REMOVING LINOLEUM ADHESIVE FROM FLOORS PART 1---GENERAL 1.01 SUMMARY This procedure includes guidance on removing the mastic adhesive left behind when linoleum flooring has been removed. Linoleum flooring was very popular from 1863 to 1974. It was used historically as an original floor treatment in some GSA buildings. Linoleum's chief ingredient was linseed oil, pressed from flax seed, which became a tough, elastic material when exposed to air. The process essentially consisted of mixing linseed oil and gum with ground cork or wood flour, and pressing it onto burlap or canvas. It was then glued down to concrete or wood floors using a mastic cement. See "General Project Guidelines" for general project guidelines to be used along with this procedureThese guidelines cover the following sections: Historic Structures Precautions Submittals Quality Assurance Delivery, Storage and Handling Project/Site Conditions Sequencing and Scheduling General Protection (Surface and Surrounding) These guidelines should be reviewed prior to performing this procedure and should be followed along with recommendations from the Regional Historic Preservation Officer (RHPO). PART 2---PRODUCTS 2.01 MATERIALS Clean, potable water Vinegar Citrus degreasing solvent such as "Limo Sol", or approved equal. Dry ice Chemical solvent such as isopropyl alcohol, paint thinner, xylol, lacquer thinner, or paint stripper. 2.02 EQUIPMENT Heat lamp or hot-air gun Putty knife or scraper PART 3---EXECUTION 3.01 ERECTION, INSTALLATION, APPLICATION NOTE: A waterproof glue is usually applied at the edges and seams of the linoleum; the center of the felt layers is usually attached with a water soluble paste. Soak the mastic area in hot water for 20-60 minutes or until soft.\ If this is not effective, try adding vinegar or high-strength citrus degreasing solvent to the water and then soak for 20-60 minutes until soft. If mastic still will not soften, try applying heat to the surface using a lamp or hot-air gun. -OR- Try freezing the mastic with dry ice to break the bond with the substrate. If no other methods are effective in softening the mastic, test a chemical solvent on the area. NOTE: Be sure to test in an inconspicuous area to determine appropriate chemicals and strengths before proceeding with cleaning. Scrape away the softened mastic using a putty knife or garden edger.
