What Pet Friendly Method Should I Use to Clear Grass Along a Chain Link Fenc

I have moved to a home with an established yard surrounded by a chain link fence and two dogs. I want to create a bed along the fence in an area the dogs seem to ignore for my hybrid iris collection. I previously would have used Roundup, but my partner will not allow it around the dogs. Salt or vinegar were suggested by I am afraid these will affect the soil composition prior to replanting. How can I clear the grass short of digging it out?

Boiling water. It is as effective as Roundup in killing weeds and has no lasting effect on the soil. Just boil some water and pour it on the plants you want to kill. Be aware though, just like Roundup, boiling water will kill any plant material it touches.

Iris

The roots are showing out of the ground. Is that a problem? Should I be transplanting?

Bearded Iris Moving in April

My bearded iris did not bloom last year and I think it is partly that they get too much shade now and partly that they need to be divided.
Unfortunately, due to where they are planted, I cannot get to them in the late summer (they are behind a huge rugosa rose against a wall).
If I move them now, when I can get at them and divide and replant, I assume I will lose all bloom for this year. But since they did not bloom last year, I really lose nothing. Should I replant now, or store in garage until later in summer? They are such a lovely color, I hate to lose them. Thanks in advance!

It should be ok to go ahead and replant them now to a more suitable location.

How Can I Prevent Weeds in My Flower Beds?

I have hens peck and other low growing vines that are so hard to pull and then they come right back. They are in my Iris beds that are raised beds.

With these weeds, persistence and diligence are the keys. You have 2 options. The first is to keep a close eye on the beds and snip the weeds off at ground level as soon as you see them appear. These repeated attempts to regrow will eventually result in the plant using all of its energy reserves in int roots and dying.

The other thing you can do is use weed barriers. Layers of newspaper, landscaping cloth and even thick layers of mulch can act as barriers. This will prevent the weeds from getting light and they will die from a lack of sunlight.

Why Don’t My Iris Plants Flower?

My irises have great green leaves but hardly any blooms! I did put some bone meal and lime on. How much or what else can I do? We live in Zone 7.

ANSWERS

The most common reason for irises failing to bloom is overcrowding. Dividing and transplanting them usually helps. In addition, it can be attributed to poor pollination. Try to entice pollinators (bees, butterflies, etc.) to the area with brightly colored flowers.

Iris Weed Control

I have a large iris patch and have a lot of clover and violets. What can I use to control or kill the clover and violets plus some weeds? Also, what sort of fertilizer should I use? I live in Georgia.

Note: To prevent harm to iris plants, you should either pull them up by hand or spot treat carefully. Boiling water can also help kill these and other weeds, but care should still be taken as to not get any on the irises.

A high phosphourus fertilizer, like bone meal, can be applied to irises if non-flowering is an issue.

Moving Iris in the Yard

I have large white Irises in the yard and want to move them, some are blooming now. When is the best time of year to move them? I live in eastern KY and wanted to know if a gardenia bush would live here if planted outside?

ANSWERS

Yes, gardenias can be planted outdoors in your area. The best time to transplant Iris is 2-3 weeks after the finish of blooming.
