Does Gravel in Pots Increase Drainage – The Latest Science

Logic would have you believe that adding gravel or pot shards in the bottom of a pot or container will increase drainage and this has been a common practice for a long time. More recently some gardening experts and scientists have declared this to be a myth, claiming that gravel does not increase drainage when … Read More

Oklahoma Food Forest


I am continuing to build up my property after taking a break after burnout last year (I spent 2-3 months of intense yardwork to prep for a wedding plus my regular gardening and home remodeling).

I have purchased a Stella Cherry tree. This is my second time purchasing a cherry tree and want to make sure I’m doing everything right to make is survive. It’s full size is up to 30′ tall with a 15′ spread. The one i have coming is 4-5′ tall.

I have a spot in the front yard I plan to put it that has more dappled sunlight than it does direct sun. I amchoosing thos due to the heat and the other trees can be thinned out later on.

My soil is horrible so I always amend my holes.

Anything special to really give this tree a fighting chance?

I plan to use strawberries as a ground cover.

I’m also bring in 2- Pecans, 2- figs, 2 hardy kiwi, 2- goji berries, 2 thornless raspberries and 2 blueberry. Also got some asparagus and rhubarb (advice on this would be great too) to put in. I only had 3 of 20 asparagus crowns show up last year.

We already have 3 peach trees, 2 nectarine trees, 1 apricot, 3 apple (one is crab apple), thornless and wild blackberries, pear tree, and wild elderberry.

Similar but unique: physiological response to drought and growth of pure species and interspecific hybrid clones of Eucalyptus

Abstract

Key message

Eucalyptus grandis and hybrids with red gums and E. urophylla exhibit different strategies to deal with long-term drought, involving differences in stomatal regulation, plant hydraulics, and growth.

Abstract

Eucalyptus species are important in commercial forestry for their rapid growth and adaptability. In the context of climate change, evaluating the drought responses of different genotypes is critical for enhancing resilience and productivity. Genetic improvement often involves crossing fast-growing, high-quality species with drought-tolerant ones. Understanding trade-offs in pure species and hybrids is essential for optimizing forest management. This study examined physiologic and growth responses to water restriction (WR) of E. grandis (GG), E. grandis × E. camaldulensis (GC), E. grandis × E. tereticornis (GT), and E. grandis × E. urophylla (GU1 and GU2) clones at the sapling stage across two drought cycles. Measurements included leaf-water potential (Ψ), relative water content (RWC), stomatal conductance (gS), pressure–volume traits, hydraulic conductivities (kS, kL), percentage loss of hydraulic conductivity (PLC), specific leaf area (SLA), and chlorophyll content. Results revealed different drought response strategies among clones. GC and GT hybrids were more “water spenders”, exhibiting high PLC (> 80%) due to limited stomatal closure, along with higher chlorophyll levels that maximized carbon gain and growth under drought. GC exhibited both elastic and osmotic adjustment, while GT showed only elastic adjustment. GG was the most drought-sensitive clone, relying on strong stomatal control, osmotic adjustment, and low cavitation, which limited carbon assimilation and resulted in the greatest growth reduction. GU hybrids shared physiologic similarities with GG but showed varying growth responses to WR. These findings suggest some hybrid clones may outperform pure E. grandis under WR, with significant genotype variation even among hybrids sharing similar parental species.

Trump purge raises extinction threat for endangered species, fired workers warn

Scientist sounds alarm over ‘canary in the coalmine’ species including beetles and spiders

Donald Trump’s blitz on federal science agencies has increased the risk of endangered species going extinct, fired government experts have warned.

The new administration, and its so-called “department of government efficiency”, led by the billionaire Elon Musk, has fired thousands of employees at science agencies, with funding halted at the National Institutes of Health and the National Science Foundation.

What do you guys think about no-dig gardening?


My parents have got a lot of olive trees. They dig up the soil for airing every year. But summer times are so dry and we don’t have chance to water it very often. Im searching about the no-dig gardening and wondering if it would help trees grow better or soil to stay more humid if we didn’t disturb the soil every year. If you know any knowledge please let me know.
