Low e will certainly effect plant growth. Ultraviolet Light (UV) Ultraviolet light is comprised of three different wavelength ranges of light. UVC (200-280nm) has the shortest wavelength and most energy, but is potentially the most stressful to plants and human skin causing sunburn and can be very damaging to human eyes. Fortunately, for humans and plants atmospheric absorption eliminates the majority of UVC shortwave light. no need for a window film to block it. UVB (280-315nm) has a short wavelength, high energy and also causes sunburn in humans and plants. UVB is known to damage protein and nucleic acids in plant cells, causing decreased metabolism and decreased number of flowers. UVB can have positive effects as well.. A plant responds to the stress and sunburn from UVB wavelengths, by creating it’s own sunscreen in the form of trichomes and cretinoid. Exposure to UVB radiation is also known to reduce a plants biomass, plant height and leaf area, but increase leaf thickness. lack of UVB causes leggy plants. Finally, UVA and near ultraviolet light (315-400nm) has the longest wavelengths of UV light and can be very beneficial to plant development. Wavelengths in the UVA spectral range are included in the absorption spectrum, particularly in the 380nm range. The absorption spectrum is the range of wavelengths of light that are absorbed by green chlorophyll for photosynthesis. Additionally, research has shown that exposing plants to UVA light can also inhibit mold growth and fungal development. Far-Red and Infrared Light On the far end of the spectrum (>700nm) you find far-red and infrared wavelengths of light. Far-red and infrared light have very long wavelengths, and very little energy. Infrared wavelengths are not visible to the human eye and only can be felt as heat. We know that blue and red light is optimal for plant development, but research conducted in 1957 has shown that combining blue light and red light with far-red/infrared light (700-760nm), led to an increased rate of photosynthesis due to the Emerson effect. The protein Phytochrome is the only known receptor that is sensitive to far-red/infrared wavelengths. Plants use Phytrochrome to regulate when a plant is to switch from vegetation state to flowering, and the time of flowering, due to the length of daylight or exposure to artificial light. The appropriate amounts of far-red and infrared light can also be a very effective at promoting robust stem growth, proper node spacing, and more flowers and fruit. Too much IR radiation can also be an issue because to a plant the majority of IR radiation is felt as heat. consider the amount of light (PAR or PPFD) needed to successfully grow your plants. then decide if low e is sufficient for you. It may lack certain lighting requirements.

1.) Yes 2.) It boils down to what your expectations are. If you want a desireable long lived shade tree then NO. If all you want is some shrubby thing to look nice in a parking lot tree island for up to 10 years then you're in business. 3.) If you go treating the stump, you could end up killing the entire tree. If you want to make it a multi-stem, you can do what the growers do which is to cut it at the base then select the best looking stems that sprout. One thing to think about is that turning it into a multi-stem isn't necessarily going to prevent sunscald in the future. That is a very common problem with silver maple hybrids.

well the small nat thing could be from a dying fruit (pepper) I will search more, as of now i cut all fruit off of plant and moved plant 50 feet away from my other pepper plants just to be safe... I am tired of playing this pepper plant game, now i have a ghost pepper which is real healthy and starting to grow lil peppers, along with a scorpian plant which is doing realllll well. with a lil birds eye pepper which is sucking up the miricle grow and is dark green and doing real good... almost crazy for so cal right now.... so I dont want want was is going on on the lil black dragon tree thing to spread.... ya feel me?

Lucky_cloud: I believe it! I assumed they would eventually return, but I’m suspicious as to how long that would take. The story behind the photo I posted is that our Knockout rose bush was sacrificed when we had some exterior work done. 5 years later it has sprouted from what must be just a root fragment. Just one little rose stem on it lol. Life will find a way! I have a few extra squares so maybe I’ll just fill those up with some new pepper plants and see what happens to these in the mean time... :)
