Natural selection must be used to eliminate weak characters of the variety or breed. What is the disadvantage of self-pollination? The tube will then be removed and replaced with a fresh one so that the pollinator can pollinate the new plant. For example, if a plant is pollinated by a bromeliad, its pollen will be introduced into its flower by means of a pollen tube, which is attached to the petiole. This is done by introducing pollen from a different species into a flower that has already been fertilized by one of its own species. In some species, however, it is not possible to remove the stigmatic stigma, and thus the plant will not be able to fertilize itself. How do most flowering plants avoid self-fertilization?Ī common way of preventing self-fertilization is to have the pollen shed in species in which both pistillate and staminate flowers are found on the same individual. Next, it’s a good idea to fertilize your plants every two to three weeks. It will also show you how much of each of these elements is present in your garden soil.

You can do this by using a soil test kit, which can be purchased at your local garden center or online. If you want to keep your tomato plants healthy, you’ll need to do a few things.
