Pests & Diseases of Agaves
Rabbits and other rodents may eat fleshy leaves or into the starchy core of a plant. These pests can be excluded by wire mesh fencing, which should be partially buried in the ground to discourage burrowing.
The main pest is Agave Snout Weevil Scyphophorus acupunctatus, a glossy black beetle-like insect with a pointed snout, typically seen in late Spring and early Summer. The adult insects feed on sap from the leaves and may introduce harmful bacteria. However, the real damage is done by their larvae which infest the starchy core and roots of a mature plant leading to wilting leaves and collapse of the plant. The female weevil lays eggs on the base of lower leaves of a plant that is ready to bloom. The consequences for an Agave monoculture, such as for the production of Tequila, can be devastating. It is unlikely that this particular species of weevil will occur outside the native range of Agaves, but other types of bugs can sometimes be seen feeding on leaves (left). Although Agave Snout Weevil prefer the broader-leaved Agaves, any genera within the Agavaceae e.g. Beschorneria are at risk.
Any snout weevils seen around a plant should be killed and a systemic insecticide applied. Prophylactic treatment with a systemic insecticide of an Agave collection within the native range of the weevil, may be advisable. Obviously this is impractical if any part of the plant is to be consumed or fermented.
Once a plant has collapsed, it is too late for treatment. The infected plant should be removed and burned, along with any grubs that can be found. Watering nearby plants with a systemic inecticide may help to control the pest.
Agave edema (oedema) is a physiological condition, so not contagious. It is caused by watering during the heat of the day when the stomata are closed or by watering on a warm, dry day just before a change in the weather causes cool, humid conditions. The leaf takes up water faster than it can be dissipated by transpiration through the stomata and the epidermis separates from the underlying tissues and balloons out under pressure. Later on the damaged areas will collapse and leave unsightly brown or white scars. To avoid Agave edema, water during early morning or evening when it is cooler.

Ruth Bancroft Garden spectacular, part 2 of 3

Late winter in the Ruth Bancroft Garden (RBG) means aloe flowers. But aloes aren't the only plants in bloom. In this recent post, I featured several different “ice plants” or “mesembs” here are some more:
|Aloe branddraaiensis, not the most spectacular aloe based on the leaves, but the flowers are really nice|
|And even more|
|Aloe 'Creamsicle', a Brian Kemble hybrid between a yellow-flowering Aloe arborescens and a yellow-flowering Aloe ferox|
|Aloe speciosa, the appropriately named tilt-head aloe, in front of Aloidendron 'Hercules'|
|Arctostaphylos 'Ruth Bancroft', with Agave ovatifolia on the left|
|Arctostaphylos 'Ruth Bancroft' and Agave ovatifolia|
|Arctostaphylos 'Ruth Bancroft' flowers|
|Agave ovatifolia 'Orca'|
|At the Ruth Bancroft Garden, it's easy to get distracted by the large, showy plants. But there's a huge variety to discover lower to the ground. Here's a good example, an ever expanding carpet of Sedum rubrotinctum.|
|Mangave 'Mission to Mars' and Aloe schoelleri|
|Mangave 'Mission to Mars', growing to impressive proportions in this sunny spot|
|Euphorbia echinus, one of the euphorbia species from Morocco|
|Euphorbia caput-medusae from near Cape Town|
|Euphorbia inermis var. huttonae (right) and Euphorbia caput-medusae (top right)|
|Large clump of Agave mitis|
|Agave mitis var. albidior and Senecio mandraliscae (left), Senecio ficoides 'Skyscraper' (right)|
|The newly restored pond|
|Senecio ficoides 'Skyscraper' from the Sunset Western Garden Collection, a great option where a vertical accent is needed|
|Unnamed Brian Kemble Mangave (Mangave 'Macho Mocha' crossed with Agave pablocarrilloi) about to flower|

Such a treat reading your post, so much eye candy and not to mention your superb photography!
Chocolate Edge, major want!!
The photo of Euphorbia echinus had me thinking of an Escher painting. It's a beautiful garden. I was surprised by the pond area but I think it looks wonderful.
That clump of Euphorbia echinus is mesmerizing. Individual plants are a bit meh, but en masse, wow!
The pond was part of Ruth's original garden but degraded over the years, as is typical of old water features. Now it looks better than I ever remember.
The group of Mangave 'Mission to Mars' is very impressive and has a "plucked from the headlines" name: I love it.
I find the small plantings in rocks to be my favorite. There was such treasure in the previous post (part #1, moss and Aeonium!) as well as the stunning colors of Cheiridopsis denticulata and the succulent grouping nestled in rocks by the pond. I'd love to see how it inspires you to create tapestries in your own garden.
LOL, I wonder if the recent Mars landing of the Perseverance rover has led to increased demand for Mangave 'Mission to Mars'?
Another scrumptious look at the RBG!
Scrumptious is a good descriptor!
I was going to go in Feb and now it's March. How did that happen ?? At least I can visit virtually via your photos-and Brian Kembles' 'whats in bloom' videos !
Agave mitis var. albidior (White Agave) – Succulent plants
Agave mitis var. albidior (White Agave) is an attractive, medium-sized, clump-forming Agave with rosettes up to 60 cm tall and fleshy, up to 20 cm wide, up to 60 cm long, glaucous-gray leaves that gracefully curve upwards. The leaves appear unarmed but have a soft terminal spine and minute, backward curving, brown spines on the edge of the leaves. The flower spike is up to 1.5 m tall and the flowers are yellowish-green to purplish.
Scientific Name: Agave mitis var. albidior (Salm-Dyck) B.Ullrich
Synonyms: Agave albicans, Agave celsii var. albicans, Agave concinna, Agave micracantha var. albicans, Agave micracantha var. albidior, Agave mitis var. albicans, Agave ousselghemiana.
Common Names: White Agave
How to grow and maintain Agave mitis var. albidior (White Agave):
It thrives best in full sun to light shade. A south or south-east facing window works great.
It prefers to grow in well-drained soil. Use standard succulent or cacti potting mix.
It prefers warm spring and summer temperatures 70ºF/21ºC – 90ºF/32ºC and cooler fall and winter temperatures 50ºF/10ºC – 60ºF/15ºC.
In spring, water this plant when the top inch of soil is totally dry. Don’t let the soil become completely dry. In the winter and fall, when growth is suspended, water very lightly. Too much water can cause root rot or cause the leaves to become pale and flop.
Fertilize with a standard liquid fertilizer every two weeks during spring and summer. Do not feed during fall and winter.
It can be easily propagated from offshoots which is the fastest and most reliable method of agave plant production. Agave plants put out offshoots from the base of the mother plants that are easily removed to begin a new plant. Growing agave from seed produces a large number of plants quickly. A moist, sterile soil mix containing equal parts perlite and sphagnum peat is ideal for germinating seeds in a warm location with indirect light. The soil must stay lightly moist until the plants are established. A clear plastic covering helps keep the soil moist during the two to three weeks until the seeds sprout, then a daily misting keeps the seedlings moist until ready to transplant.
Pests and Diseases:
It has no serious pest or disease problems. Watch for mealybugs and scale.
