If they were able to grow, then they obviously weren't planted too deep. Most sunflowers can be planted up to six inches deep and still germinate, though it will take longer to make it to the surface.
Yes, bamboo can grow submerged in water, as long as the water is not too deep and the plant has access to oxygen.
In the tropical place because in the tropical temperature it is not too hot or too cold
Unless you grow a dwarf type of sunflower, such as "Teddy bear" you would not grow them in pots. Most sunflowers grow tall, and become rather top-heavy. Sunflowers need lots of room to grow--including the roots, which need to spread out beneath the soil in order to anchor the plant. Even muli-stemmed sunflowers, whose individual flowers are fairly small (for a sunflower), get top-heavy because of the number of flowers on the stem. So, if you absolutely MUST grow one in a pot, select the shortest cultivar you can, and still put that in an over-sized pot. So, sunflowers grow better in the ground, but it is possible and challenging to grow them in pots.
The leaves and stems of a sunflower are green -- they are reflecting, not absorbing, green light. The colors that give the plant the most energy are at the purple end of the spectrum (red and blue) - those colors with the highest light energy.Blue light - responsible for vegetative or leaf growth (fluorescent light)Red plus Blue light - encourages flowering (full spectrum or "grow lights)dark colors, not light
If u want to grow up a plant for tomorrow,, start a new plant! You can plant a plant with milk, it grow ups for the second day and it is too easy.. For know how plant a plant with milk, search here: How a plant with milk can grow up? good luck!
yes but if you put too much the plant will die
A plant willcertainly not grow if you soak it in water. All living things need air. Any type of plant is a living thing. And it needs air too. So no, a plant will not grow if soaked it water
Insufficient sunlight or water. Some plant seeds will not germinate if the temperature is too cold.
If plants get water they will grow and you will have a beautiful plant. Well they need sunlight too.
The level at which a seed is planted can affect its growth due to factors like soil quality, sunlight exposure, and temperature. Planting seeds at the appropriate depth ensures they receive enough moisture and nutrients to sprout and grow successfully. Planting too deep or too shallow can lead to slow or unsuccessful germination.
may Some sunflowers take longer than others to mature---plant most when all danger of frost is past or start seed indoors and put plants outdoors in spring. The smaller varieties can be planted as late as July.
heat but you have too put water in the plant
