It's Easy to Plant your Black Knight Butterfly Bush

Step 1 - Dig Your Hole

Select a site with full to partial sun and moist or well drained soil for your Black Knight Butterfly Bush.

First, dig each hole so that it is just shallower than the root ball and at least twice the width.

Then loosen the soil in the planting hole so the roots can easily break through.

Use your shovel or try dragging the points of a pitch fork along the sides and bottom of the hole.

Step 2 - Place Your Plant

Next, separate the roots of your Black Knight Butterfly Bush gently with your fingers and position them downward in the hole.

The top of the root flare, where the roots end and the trunk begins, should be about an inch above the surrounding soil.

Then make sure the plant is exactly vertical in the hole.

To make it just right, use a level.

Step 3 - Backfill Your Hole

As you backfill the hole, apply water to remove air pockets.

Remove debris like stones and grass and completely break up any dirt clumps.

Water your Black Knight Butterfly Bush again after the transplant is complete.

To help retain some of that moisture, it's recommended that you place mulch around each plant to a depth of 2"-3" up to but not touching the trunk. Organic mulches such as wood chips also help to better soil structure as they decompose.

I ordered two of these, one died and the other grew at a fantastic rate. Planted it in late April and it was about 3 ft high in some places by mid-July. Really beautiful and the butterflies practically swarmed it

Our Butterfly Bush was packaged well and arrived safely. There were actually three bushes in that pot and I planted one in my 'secret garden,' one in the front yard and gave one to my neighbor. All three have responded well to their new environment and produced beautiful deep purple blooms within a very short time which I enjoyed tremendously. It seems every time I sat down and enjoyed the blooms, I saw at least one butterfly. You weren't kidding! Thank you so much for the wonderful addition to our home

sun sensitive
made the mistake of putting it where it gets partial sunshine(due to seasonal movement of sun), now growing only one direction to reach the sunlight, but not really the plants' fault! Still attracting butterflies though!!

I bought one of these last spring and planted it in early June. It grew and had beautiful, beautiful flowers on it! I was looking forward to it blooming again this year, but unfortunately my new lawn service guy cut the bush right to the ground today! I will have to buy another one ASAP to get it in the ground for this season

I bought this plant in the spring and it is not exactly what I was thinking. I thought it would grow straight up, but does not. It is very unruly and is staying close to the ground - no trunk yet and now it is August. I do have more branches and it has stayed healthy despite being moved once already, but this looks more like a weed than a bush. It has nice purple flowering ends, but not 1 butterfly has been seen on it. I live in IL so maybe that has something to do with it? I have seen bees on it, but I bought for butterflies. I wish I would have purchased this locally where the bushes grow straight up and I saw butterflies on them. Oh well

Do deer bother this bush?
A shopper on Sep 8, 2014
Best Answer: My plants were located inside a fenced yard, so the nearby deer couldn't get to them. Unfortunately my plants didn't survive the unusually cold weather we had last winter near Washington DC.

Does this take full sun?
A shopper on Jun 7, 2014
Best Answer: I purchased two. One was placed in an area where it had limited sunlight exposure and did very well. The other was placed in a different location with full North Carolina sun all day. It did not do nearly as well. I have had butterfly bushes before that did very well in the sun. Both are now emerging into their second season. Looking forward to how they will respond to their surroundings without the trauma of initial transplantation.

How long does this bush bloom?
A shopper on Oct 6, 2014

do these bushes come back from the ground or the plant think mine died but are shoots at the base?
sandy w on Jun 15, 2014
Best Answer: If it still has shoots coming from the base, it's not completely dead. I would make sure that the roots are covered and that there are no air pockets around the roots, and give it water. Maybe you could buy some of the special planting mix that fast-growing-trees.com sells? It has lots of nutrients that growing butterfly bushes need.

I am seeking Buddleja Todaras (LAVENDAR Nectar Bush) Is this the correct one? I'm concerned that Black Knight would be a dark purple which I would not want. I am not a wholesaler; can I still purchase from you? Do you have any outlets in San Diego County?

Best Answer: We carry the Buddleia davidii 'Black Knight' bush and it has darker blooms. We are located in SC.

Will my Trees and Shrubs Look Like the Photographs?

Most trees and plants on the website are pictured in their mature form. Depending on the product and growth rate, mature development can take years for your plant to resemble the photos.

Picture the last time you took a walk in the woods. The young trees were not miniature bonsai versions of mature trees. Instead they were naturally thin and lanky. Young trees are programmed to race toward the light, before the competing vegetation crowds them out. Once established at 10 feet or more, they start developing a wide canopy and shedding lower limbs.

Bare Root trees are shipped without dirt or any green foliage showing. Some customers who have never planted bare root before, think that they received a "dead stick" with roots. These dormant trees are basically sleeping over the winter as most trees do. Because of their hibernation-like stage, this is a great way to transplant these trees. Since a bare root tree lacks foliage, they need very little moisture.

Most Trees and Shrubs are Pruned Before Shipping... at No Cost to You

Pruning makes plants appear to be less-full than the ones you may have seen at your local big box garden center. A retailer's goal is to have plants look their best while sitting in the store. Our goal is to have them look the best after you plant them.

Pruned trees and shrubs not only travel better, but become established much quicker. So rather than supporting extra foliage, they put their energy into sending out deep roots. Once that happens, your plants become hardier and quickly explode with new top growth. Above the ground, pruning helps your plants develop a more attractive form.
