Hello, I was wondering how many use a foliar feeding on their daylilies.If so what is it and how often is it applied?
Mine are planted closely and sidedressing now would be difficult. I have been busy with the wedding and other family affairs. Just wondering if this could help them green up!

Thanks,
Teresa

I use Miracle grow that I add to the water and pour over the foliage.
(I have a small city garden so watering by hand is not a problem Whistling )

During the summer I apply it about once a week, I think (more or less)

I use a 16-4-8 or something close, I buy from the Farmers Co-Op, its a lot cheaper buying it in 25# bags than what you get at the box stores. It's applied every two weeks.

What is the name I need to ask for? We have a Rural King and a Southern States?
I have used the M. Grow that goes on the water hose before.

THanks for posting.

While I was searching info on foliar feeding I read that no plant can asborb P by foliage, and if the P is high it can damage foliage.
So a foliar feeding should be ony N-K and not the common N-P-K. It should be applied on leaves and not on flowers.
Does anyone know about this story of phosphorous being dangerous to foliage?

It is not true that no plant can absorb phosphorous via the leaves. The plants will take up more foliar applied P if they are P deficient, however. Older leaves may not benefit as much from foliar fertilization either. Not specifically for P, but yes, highly concentrated foliar fertilizer can damage the leaves. Some nutrients aren't well translocated from the leaves to other parts of the plant either. I don't know why one might want to apply fertilizer to flowers? Confused

Don't forget also that plants need more than just NPK. Foliar applications are often used to supply micronutrients, especially when soil application may get "blocked" by the soil pH. It doesn't matter how much NPK you apply if any other nutrient is deficient, any nutrient deficiency will have a negative effect on the plant and limit its performance.

Foliar fertilization can give plants a boost and may get a quicker response than applying to the roots but plants do need a lot of NPK so I believe foliar application is more useful for plants growing in the soil where nutrients are naturally present even if not fertilized. If you were to try and supply all the NPK (and other nutrients) via the leaves to plants in pots then it might be difficult to provide enough without damaging the leaves.

I have used Miracle Grow in the past (I had the dispenser that attaches to the end of a hose), but have switched to time released BB's 16-16-16. It's more work to fertilize the plants, but I only need to do it spring, and early fall, rather than every week or two with the foliar application. I have been thinking of switching to something with a higher N, from what I have seen that is really what Daylilies love, and enhances performance.

Sue, I had to laugh because I always come up with some nonsense read on the internet Hilarious!
I wonder why people writes articles like that. Internet is such a dangerous place!

Well there is an element of truth to it, but the first part is an exaggeration, plants can take up some P through the leaves although maybe not as well as some of the other nutrients. Another common statement is that you need to foliar feed when the stomata are open. In fact studies have shown that nutrients are taken in from foliar application better at night when the stomata are closed. There's also less risk of damaging the leaves then.

I am wondering if it would be best to use Osmocote and just be careful and put it around the base of each clump. Careful, not to get it on the leaves. ??

I apply a twelve month slow release when the plants are planted in the fall or spring, the foliar feeding is just a little booster, unless you apply it every day.

Fred do you think a scoopful would be ok around the base? I don't grow in pots.

If there clumps I would put two tablespoons, sprinkle it like your putting salt on your grits, around the entire plant.

Teresa - That is what I use and my plants bloom like crazy! I love that slow released fertilizer.

That's what I use too (that Osmocote, I buy from Amazon every year) - for my daylilies and clematis.

It's a 15-9-12 formula. That's a very good formulation for daylilies, but people should be aware that in certain soils, phosphorus can collect, or "bind", and there is a real possibility of inducing phosphorus toxicity through over-application or years of accumulation.

Because most good garden soils contain adequate amounts of phosphorus and potash, many daylily growers are using fertilizer formulations which are higher in nitrogen.

There's a very good link on Rich Howard's CT Daylily site;
http://www.ctdaylily.com/trimmer_fertilizing.html

A soil test is always advised in order to establish a baseline for future feeding.

As a side note, periods of high temperatures and humidity along with plentiful rainfall have been known to cause some time-release fertilizers to "dump". That's worth looking into as well. I don't really get that type of weather, but because I grow in containers (which often run warmer than the earth), and water lightly but more often, I apply time-release fertilizers at reduced rates, as a "nutrition insurance" baseline, and supplement with liquid fertilizers whenever I feel the plants need a little boost. For that I use half-strength Dyna-Gro Foliage Pro (9-3-6) to which I add nitrogen using General Hydroponics FloraMicro (5-0-1).

Guess I'm a bad Mommy. My daylilies don't get much fertilizer at all. I do top dress with my home made compost when I have it and last year used some chicken compost from the university here in town one time. I have used Spray and Grow and Bill's fertilizer years ago and just ordered some more to try this year and see if I notice a difference. I use Osmocote on my clematis, peony and to renew my potting soil in containers when I reuse it, but haven't tried it on daylilies.
