Why Do My Cuttings Keep Dying?
Comments (10)The rooting of cuttings is energy-driven, and most houseplants 'peak' insofar as their energy levels are concerned in late summer, so late summer will find hobby houseplant growers realizing their highest strike %s if they follow a few simple guidelines. Oxygen is an element essential to the success of cuttings. You want LOTS of air in the medium you're using to root cuttings. Use a coarse medium that doesn't support perched water; or, if it does support perched water, be sure you use a container deep enough that the proximal end (closest to the roots) of the cutting is NEVER covered by a film of water. Think 'DAMP', not 'WET'. You'll also want to reduce the leaf surface area in most cases, eliminating some leaves or cutting them across the veins. This is to help reduce the amount of transpiration. If the plant can't keep up with the volume of water lost through foliage, the plant will SHED the foliage as a normal drought response, which is not conducive to rooting. Essentially, when you're trying to propagate cuttings, it's a race to establish a healthy hydraulic connection between roots and shoots before fungal organisms rot the plumbing. For that reason, try to steer clear of a medium that contains any form of mineral soil - garden soil, topsoil, unsterilized sand ...... Here is an effective way to keep humidity levels high & assure a high success rate: Neatly cut the top of a clear gallon jug. Stick your cuttings in a coarse, sterile medium like washed and screened perlite (in open shade). The plastic tray has holes in it so it drains after you water the cutting. After the cutting strikes, remove the screw on cap to allow more air circulation, then gradually remove the 'tent' entirely. I've probably done at least 100 cuttings to share already this summer using this or a similar set-up. Here is a Ficus microcarpa recently rooted under the milk jug for a friend. Notice the wick hanging down to drain excess (perched) water from the soil - practicing what I preach about the 'damp, not wet' thing. Let me know if you want a pic of some of the other cuttings done in such a manner; especially let me know if you have questions ..... Al...See MoreRose leaves turning brown but not drying or dying..
Comments (1)They appear to have suffered a freeze to me. It isn't surprising your tree rose foliage isn't affected. Cold air sinks, pooling at the lowest levels. The coldest air could have been below the head of the standard where the lower foliage would have suffered the cold damage. It could also be the genetic difference in cold hardiness of the foliage between the variety shown and that budded to the tree, or both. The leaves are softer, thinner and more susceptible to freeze damage at higher temps than the canes. Kim...See MoreHelp! My cuttings leaves have all turned brown
