The soil is damp right now. Not wet, nor what i'd call soggy, but is damp to the touch. It last rained 2 days ago I think. Grew them in the same place last year, so the drainage hasn't changed... they did great last year :/

Hi - I am no expert (I am having my own problems as well) but is there a chance that it could be sunburn? If there was a string of sunny days before the edges started turning brown, and the plants were indoors previously, I think that could be a possibility. Good luck and green growth to your leaves!

Any damage that is showing on your plants is mechanical - that means it came to be from shipping and other transport, handling or jostling. It is not the result of diseases or insects nor does it look like any watering issues. In reality, these plants look pretty darn good considering most big box stores do not take the slightest bit of care with their plants (hence the evidence of damage you are seeing). As to fertilizing, you need to identify your plants and then do a bit of research, as not all plants benefit from similar fertilization methods nor do they require it at the same time. Cacti and succulents have different needs than do tropical foliage plants and flowering houseplants (orchids, African violets, flowering gift plants) have yet another set of needs. In general, an all purpose liquid fertilizer used at 1/2 to 1/3 strength with every other watering is appropriate for most tropicals during their primary growing season (March through October) but you can get by with quite a bit less. I'd suggest you post this on the House Plants forum both to get accurate ID's on your plants and their advice as to when, how much and with what to best fertilize what you have.

the plant is perennial ... the canes are biennial ... after a cane fruits .... berries.. whatever ... it dies... and is cut out [usually in spring.. when it shows no sign of life] ... later in the season ... new shoots emerge ... and those will berry the following season ... and continue the cycle .... they look like they are short of water ... run your drip system... then go dig some small holes near the plant ... and find out.. if you are running the drip long enough.... to get water to the root zone of the plant ... meaning 3 to 8 inches down.. where the roots are .... just use a hand trowel.. or a sharpened old tablespoon ... minimal sized hole .... in my sand.. i would have to run the drip 3 to 4 HOURS ... ... i have no clue how many gallons that is.. it really doesnt matter ... its all about how water moves thru your soil ... thru the root zone ... imo.. with years of drip take experimentation ... i found out.. that no one can tell you .. how to water in the soil in your garden... and all you are left with is digging holes.. and finding out ... sooo .. if those fruited this season ... they are going to be dead come spring.. so who cares what they look like now ... my attention would be don on new emerging shoots.. and how they look ... in other words.. there is nothing to do about.. nor worry about ... you state they are not proper.. but i cant find them in your pix ... as the canes decline .. towards death .. they do continue to process sunshine.. to store energy in the roots ... dont go cutting them out because they are ugly ... there are full sun plants .. i hope the shade seen in the pix.. are the max shade for the day .... ken ps: in pic 3.. whats the wire.. and twine.. and what not????
