Just got my first greenhouse & the Mississippi River is already testing my setup

I live in a stilt house on a small island on the Mississippi River in northeast Missouri, I’ve been here just over a year & have been wanting to start growing my own food as well as flowers to sell for extra cash in town. I finally got a way to do it figured out since I can’t put down raised beds or anything permanent on the ground & even using stock tubs wouldn’t work since trying to move those when they are full when a flood is coming in would be a disaster. My deck is too tiny to really do anything with also.

My mom (thanks neighbor!) helped me get this little greenhouse & pontoon to set it on & it just got delivered last weekend. The river decided to start coming up past flood stage a few days ago & still has about another foot predicted to go. So, we had to scramble to have my dad help secure everything today (greenhouse to pontoon & steel-cabled the pontoon to a couple of the concrete pillars my house is on). Thankfully I have a full set of waders to be able to get to the pontoon even if the flood comes up more than predicted this time or in future worse floods :)

One big question I’ve got is, can I use the river water for extra nutrients? Or would that not work? I’ve been keeping a couple house plants alive & watching lots of YouTube & but any tips for a newbie greenhouse gardener would be super appreciated, thanks!

Pineapple finally growing from a store bought cut top.

We have had this pineapple plant for 5-6 years. It came from a store bought pineapple cut top that my sister planted. We thought it would never grow a pineapple & just be a cool plant, but last year it started getting really a lot bigger. This year, it finally happened! A small pineapple started to form, now it’s taking off. This growth so far is astonishing! It seems to almost double in size by the day!!!!!

Pictures 7 & 8 are less than 24 hours apart 😳 Do pineapple’s usually grow super fast once they start to form??? We are so excited lol 😂 🍍

What happened here?

So my guess is, grafting and different speed of thickness growth?

Seen in Mannheim (Germany).

The other trees in the street were either the one or the other kind, why would you graft two of these together?

Just bragging on my Azaleas!! I love them sooooo much. I know they need trimmed but I didn't get to it in time this year before the blooms. I will when they're done so we can see out of the windows again lol

Gardening takes over my life part 2

I have adhd and always fixate on random stuff. This year I decided to start a fig nursery 🤣

All these years I’ve been mass gardening and today I made $960 selling fig trees. Holy smokes

Spring has SPRUNG!

Southeast VA zone 8b

Moved to VA from MA 9/24. Last spring dug up my front lawn and made a pollinator garden and holy shmoly do things grow so much faster here. Cannot wait for summer #2, have so many plants that I started from seed to be planted in any empty spots....but the empty spots are shrinking by the hour as everything is busting loose with this weather we are having (bright sun, low 80's)!!! How are things for you?

Red cage mushroom aka basket stinkhorn

I found this colony of mushrooms in the garden today. Apparently they have a horrendous smell to attract insects, but these did not smell. Maybe after first emerging from their white 'egg' structures? This one seemed a little older. Happy spring everyone!

Hugelkultur Question

First year gardener here… looking to fill these up with top soil and compost soon. 8x4x1 bed.

Are some of these logs too large to use at Hugelkultur? I know they can take years to decompose. A couple of them easily take up 5-6 inches of depth. Will they interfere with some of our plants root systems? Can the roots grow around the logs or tap into them for nutrients? Anything I’m missing?

Any insight would be greatly appreciated.

Thanks!

Should I dead head these hydrangeas?

Just moved into this rental in November, love hydrangeas but not sure what kind these are and if I should dead head them to promote new growth. Property management didn’t give any instructions on how to care for them.

Starting my pollinator garden :)

San Diego, CA - I started my pollinator garden in my raised flower bed this weekend. I’m going for a “cottage-y vibe” - see picture 2. 💐

So far I have foxgloves, delphinium, lavender, salvia, gaura, columbine, alyssum, and creeping thyme.

If it gets too crowded I may move some of my flowers to another raised bed I have.

What to do about hostas

We bought a house in November and are now just discovering the plants we inherited. The front walkway seems to be filled with hostas. This is good because it’ll fill in without much effort! This is bad because I don’t like hostas and wanted to do something more colorful like creeping phlox. I also, not knowing anything was there, planted some peony bulbs where the hostas are now coming up. Is there an easy way to remove or at least thin out some of them?
