In Clark County Nevada do tomato blooms need to be set with some kind of spray?
To a gardner from a gardnerNO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IF you do that your tomato bulbs wont look their best or grow as big. You should not put anything but water and sunshine on them and some miricle grow. :) FROM A FARMER...farmers use auxine spray which is a plant hormone to help tomatoes set, this is because the tomatoes need "shake pollination" which is something bumblebees do but common honey bees normally used for pollination do not. you can of course "shake" the plant but in large scale farming its not economicalN777-YOU CALL YOURSELF A GARDENER WHEN YOU ARE SAYING THAT TOMATOES GROW FROM BULBS!*to whomever wrote ^^^ I fixed some spelling checks and notice how you also said tomato bulbs.
How does light and darkness effect the growth of plants?
Most plants get energy by photosynthesis, a process in which the plant's cloroplasts asorb the energy from the sun and convert it into processable energy. When a plant is in darkness, it cannot asorb sunlight, therefore it won't get sufficient energy. When gardining, be sure to provide the plant with adaquate light, but not too much or the plant could die.
