My lemon tree has an 18-inch circumference. Do I really need 18 spikes (1 spike per inch)?

No! you need to measure or estimate the diameter of the trunk of your tree about 1foot above the ground. 1-2 inches takes 2 spikes 3in.3, 4in.4 and so on. the circumference of the tree makes no difference. the spikes should be placed at least 30 inches from the trunk of the tree. Spikes need to be placed at the drip line around the circumference of the tree. If your tree is only 18in. at the drip line it is probably to small for spikes.

I believe instructions are to use one spike per inch diameter, not circumference. Check the instructions again to confirm. I am certain that you do not need 18 spikes for your tree.

So, the rule is 1 spike per inch of TRUNK DIAMETER, not the limb circumference. My peach trees are ~10 ft. tall, have about 3" diameter trunks and 8 foot limb spread (~100 inches) and I feed them with 3-4 spikes each. Its kind of confusing because it says to place them around the drip line (limb diameter), but the number of spikes is figured from the trunk thickness (in inches). You'll need a caliper (micrometer) to figure, I bought a Hornady brand here on Amazon for $18.

The tree's circumference is easy to measure and is directly related to diameter...the diameter is equivalent to circumference divided by pi. In your case, that is 18/3.14 or 5.73. You will need 6 spikes.

The spikes are about 4 inches long. You could simply cut them down if you wished, but as they are cut shorter I would think they would be less effective. They are very thin and do not show much.

Gilbert, you only cut off a tiny piece of the end. I've used these spikes for years when I go on vacation.depending upon how much water you'll need you can also use a 1 QT (liter) bottle.I only use mine around my peppers and toms. while I'm gone for about ten days!need more info just ask. Len

There are no spikes, I put an orange 1/2 on the center hanging pole, not very convenient.

I don't know for certain, but the purpose of the spike is to help the plant bloom. Period. I would count on a different product for your purpose.

It is a function of tree size, and based on the circumference about 4 ft off the ground. We did this last year, so I don't remember the exact amount, but our trees are mature, about 10-20 inches in diameter. (circumference is about 3 times the diameter -- I'm a math teacher, sorry) We used about a half gallon per tree, on average. You should be able t go to the Bonide website for an exact answer. By the way, we switched to a granular systemic this year -- it was easier, but still pricey for mature trees.

There are different spikes for evergreens. Evergreens need a different nutrient mix then trees and shrubs so it's best to use the evergreen spike for evergreens and tree and shrub spikes for trees and shrubs. I have quite a bit of trees, shrubs and evergreens so I've used both spikes for years and they do a great job. My trees (all types) look great!

Yes there is a spike. It's about 4 or 5 inches long and is made of plastic.

I think one foot per pot, less the root ball of the plant. I cubic ft. per pot would be more than enough.

I suppose they could be trimmed to shorten the length but the spikes are a bit brittle and cutting might shatter the whole spike. Hope that helps.

Yes. However, I would set it up a week before you leave and make sure the water is getting to the plants. I live in the desert southwest and the spikes have worked for me for over a month at a time.

It comes w/ a quite substantial metal spike that fits snuggly into the bottom of the post that you see in the picture. It should be adequate in most types of soil. Overall I thought that these were very well made for the price.

No, i did not need the spikes since my floors are hard wood. On carpet however, I would recommend them.

Get a mallott and pound in the spikes should be okay, trellis hooks up to the spikes you pound in the ground.

Yes you can use the spikes for houseplants but not a full spike. I noticed when using a full spike the leaves burned. When using the spikes you want to use pieces of s single spike or dissolve one spike in a bottle of water then feed quarterly.

The spikes must be 10" from the main stem of the bush. They work great on the roses in my yard

It depends on the diameter (i.e., trunk width at 1 ft from grade) of the trees. If 1-2 inches, then plan on 2 spikes per tree. Above 2 inches, its basically 1 spike per inch diameter.
