Its fair to say that the goal of many gardeners is to create a self-sustaining yard.

So you might think that active spreaders would be welcome in the home garden.

What do I mean by spreaders?

It can be dropped by birds and will grow anywhere, and more frustratingly, its usually not evengoodmint.

But when you do get good mint, though, remember that it will spread.

In fact, mint will spread beyond a container through the roots.

For that reason, you should keep it in a planter on concrete to contain it.

I was excited to growhorseradish,and why wouldnt you be?

Save a few roots for spring, so you might replant.

Fennelis such a jerk.

So it demands its own space, and then proceeds to take over that space and anything nearby.

How much fennel can anyone really use?

Less than I am growing, for sure.

Diligent thinning, and really considering if you actually want fennel to begin with, is warranted.

Astersare actually wonderfulthey’re usually native, and an ideal late-season flower.

The same could be said for yarrow, which blooms all season long.

However both will self-seed themselves into infinity and beyond, taking over any space, including your lawn.

Dont be afraid to tear them out by the bunch, ideally before they go to seed.

I dont know why people growlemon balmon purpose.

Grow lemon verbena or lemongrass instead for an annual herb that has many of the same properties.

Savoryis a delightful green that I enjoy mostly to force garden guests to try the shockingly lemon-tasting leaves.

But also, savory is a fast spreader, and it will take over the space.

To keep it in check, actively dig out full divisions of the savory throughout the season.

Do not let it go to seed, which it will cycle through multiple times a summer.
