Question 1

When is the best time to fertilize my American pokeweed?

Accepted Answer

If you grow your American pokeweed outdoors each year, this perennial plant will send new growth shooting out in early spring. The emergence of those leaves is a sign that the time is right to begin fertilization for the year.

Often, a American pokeweed will perform just fine with a single application of fertilizer when the spring arrives. However, if you wish to maximize the growth of your American pokeweed, you can repeat the feeding multiple times throughout the spring and early summer. If you choose this route, you can feed your American pokeweed about once every month to a month and a half.

Question 2

When should I avoid fertilizing my American pokeweed?

Accepted Answer

In the late fall and winter, your American pokeweed will enter a dormant phase in which it will no longer produce new growth. At this time, you should avoid fertilizing your American pokeweed. If you choose to fertilize multiple times during spring and summer, you should begin reducing your fertilization rate as summer approaches, as your American pokeweed 's growth rate will also slow.

Overall, it is never a wise choice to fertilize your American pokeweed during times when the weather is unseasonably hot or when the soil is extraordinarily dry. Fertilizing in either of those cases can stress your American pokeweed and cause it to perish prematurely.

Question 3

What type of fertilizer does my American pokeweed need?

Accepted Answer

Fortunately, choosing the best fertilizer for a American pokeweed is a very straightforward task. These plants will thrive on a general-purpose garden fertilizer that has equal amounts of nitrogen, phosphorus, and potassium. A fertilizer that has a ratio of 10-10-10 or something similar will be very effective. When in doubt, be sure to avoid fertilizers that have high amounts of nitrogen.

Most of the best fertilizer for a American pokeweed will come in a granular form. These fertilizers should be slow-release and will be very easy to apply to the soil. It can also be helpful to feed your American pokeweed using an organic soil amendment such as compost.

Question 4

How do I fertilize my American pokeweed?

Accepted Answer

Wait until your American pokeweed has just barely poked its first leaves through the soil's surface in early spring. Once you see that sign, apply a granular slow-release fertilizer with a balanced formula to the soil that surrounds the base of your American pokeweed.

You can repeat a similar process later in the season if you choose. When reapplying fertilizer to a American pokeweed, you should, again, apply the fertilizer to the soil at the base of the plant rather than to the plant itself. At times, this may require you to move some leaves out of the way to access the soil above the roots. It's also often a good choice to water your American pokeweed before and after you feed it.

Question 5

What happens if I fertilize my American pokeweed too much?

Accepted Answer

The American pokeweed doesn't necessarily need to receive high volumes of fertilizer each year, which means overfertilization is entirely possible. If you overfertilize your American pokeweed, you will likely notice first that the leaves have turned brown.

Overfertilization of American pokeweed is especially common if you use a fertilizer that has higher concentrations of nitrogen. High nitrogen content will likely cause the leaves of your American pokeweed to become discolored, lose much of their moisture, and begin curling at the margins. Many gardeners avoid such complications by limiting fertilization of their American pokeweed to once per year in early spring.
