To help you along with your succulent endeavours we thought you might like to have a glimpse of what we've learned throughout our 30 years of 'succulent' growth.Soil:
We've found that the best 'soil' for succulents is not a soil at all. It's a soiless mix!
We use Pro Mix, or Sunshine mix number 4 or 8. To this we add perlite for enhanced drainage.
Pro Mix is available in a 3.8-foot vacuum-sealed bag weighing about 55 lbs, If you buy one we will add the perlite and mix it for you in our mixing machine. Mixing it by hand is quite a chore.
For convenience to our customers, Solar Gardens also sells a bag for $3 that is enough to pot up about 2 ten inch bowls. If you require a larger bag, please don't hesitate to ask as we have other sizes available.Terracotta Bowl:
Any inexpensive terracotta pot will work for potting up succulents.
When choosing a pot for growing succulents, make sure there is a hole in the bottom. If there is not, you will need to put one in. Use a Dremel with a bit used to put holes in ceramic tile. The bit is available at Home Depot or other hardware stores.
Terracotta draws a lot of water away from the roots of the plants when over-watered. It also retains a lot of heat collected from the sun during the day, keeping the roots warm in the nighttime low temperatures. Remember that cold, wet roots kill cacti and succulents!Water and Fertilizer:
At the beginning of March, we use a mixture of one rounded teaspoon of 20-20-20 fertilizer to a 2 gallon watering can. Never use chlorinated water or water from a water softener as the salt and chlorine may harm your plants.
Too Much or Too Little Water?
- From March to October, use fertilizer every time you water.
- From October to March, do not use fertilizer when you water (which will be infrequently).
- From March to October, water succulents as needed when the soil throughout the bowl becomes dry.
- Remember that these plants are used to dry conditions, and thrive on neglect.
- It is actually better to underwater these plants than to overwater.
- For example, when your pot becomes very dry, your plants may become a bit soft to the touch and wrinkly. This is a good sign that the plant needs a drink.
- When succulents are over-watered (and we see this especially in winter November through March when the days are considerably shorter and cooler), they may die or their leaves turn yellow and fall off (usually beginning with leaves closer to the bottom).
- In March and April we definitely err on the side of watering less, sometimes only watering once or twice monthly.
- In the months of October to December, do not fertilize.
- During winter months, succulents need only enough water to keep the roots alive. In reality, this amount of water is very little. With light levels low and our days being so short, water sparingly during these months (ie. infrequently and with only a small quantity of water).
- If the leaves start to turn soft, wrinkle or drop (in that order) then your succulents need water desperately.
- If your leaves drop without first having turned soft then wrinkly, that is a sign of overwatering.
- Many people's succulents begin to stretch in January as the days start to get longer. This is a telltale sign of overwatering in December or January.
- If you want your plants in your bowl or arrangement to remain more compact and not grow as much, do not water as much at any time of the year.
- However, if and when your plants do stretch, use a sharp pair of scissors or shears to cut the plant back near the bowl. Always leave a few leaves on the stem to ensure a few pups of growth.
When purchasing fertilizer, one should not buy the largest container or quantity available. Buy smaller quantities at a time. When fertilizer sits on your shelf too long, it will turn hard and become difficult to accurately measure. We sell 20-20-20 in a 500 gm container. This size is not available at most garden centres, but this is the only way that we like to sell it in order to limit your waste and unnecessary cost.Overwintering:
Many, many people do not want to overwinter their succulents and that is just fine. No need to feel guilty. However, many avid gardeners do want to overwinter their succulents and that is great too. Today, succulents are more affordable, less scarce, and prices are more reasonable than in the past. Understand that every living plant (like us...unfortunately) will die at some point. However, succulents will live a lot longer than a dozen cut roses that will last a week (if you're lucky and will cost at least twice as much) even if you're changing their water everyday.
Succulents can outlive annuals and many perennials simply by understanding their seasonal growth habits. Solar Gardens' succulent class bowls cost $65 plus tax (but contain at least $125 value if all plants are purchased individually), are in a 10" diameter terra cotta bowl and contain 13 to 20 different varieties of succulent plants. These plants should surely last the spring, summer and fall (6 or 7 or 8 months) with little to no care outside on your patio or balcony. Keeping that in mind, if you would like to try to overwinter your succulents as some avid gardeners do (and again..don't feel guilty if you don't), here are a few tips:
Since winter days are so short, the plants really prefer to stay dormant (alive, but not growing) and they still need as much light as possible to stay alive. So putting them in a garage or basement or closet with no light will kill them. During this time they require vastly decreased amounts of water since they are not actively growing. Plus, succulents are desert plants and require little water to begin with even when they are actively growing.
We have found that most people kill their succulents during the winter with too much water (and not enough light - see the "Grow Light" section below). During the winter, succulents will still need a bit of water. But how much is "a bit of water"? Well, that is a very hard question to answer since the amount of water they need depends on many variables, such as - how warm or cold the room is, how much (or little) light they are receiving, how many plants are in the pot, how big (or small) the pot is, what the pot is made of (ceramic, terra cotta, glass or plastic), how big (or small) the plants are, and how much drainage each individual pot allows (if it has drainage at all). In general, a good rule of thumb is to add a small amount of water if the soil is exceedingly dry. With our class 10" terracotta bowls, you might add a cup of water occasionally during the winter but only if the soil is very dry.
So in a nutshell, most succulents die during the winter dormant period from COLD and WET roots. The key is to water infrequently with a small amount of water, just enough to keep the roots alive during dormancy. When overwintering, succulents prefer a sunny window (south is best), hardly any water, and a temperature above freezing.
The absolute BEST way to overwinter succulents is under grow lights....Grow Lights
For those that are very serious about overwintering succulents we highly recommend grow lights. We carry a fantastic, amazing type at our Avalon shop.
Lastly, don't be too upset if you haven't overwintered your succulents successfully. Like most things in life, it takes trial, error, time and patience. Not everything works (and grows) successfully all the time....unfortunately!Who Doesn't LOVE a Summer Holiday? Succulents are no Exception!
Whether you've overwintered your succulents or purchased new ones in the spring, fall or winter, they ALL enjoy a summer holiday outside. But you should be aware of just a few things before moving them outside.
#1. When placing outside NEVER let them freeze. Often we play it super safe and bring them indoors for the night if the forecast minimum is for +3 C. It's OK to leave your plants out during the day if it is above freezing, but in the spring we generally don't put them out during the day unless the temperature is going to be about 8 C or above. Of course some prefer not to put them out until about the 3rd week of May when (hopefully) the freezing is over and you don't have to bring them in at night. Whenever you put them out, keep an eye on your weather app.
This is equally important in the fall if you plan on bringing them in to overwinter.
#2. It's really hard on your succulents if you take them from your low-light houses, greenhouse and/or grow lights and put them out in direct sunlight. If placed out in the sun without acclimatizing, they will sunburn for sure. The sunburn won't usually kill the plant (if it is not too severe), but it will create dead looking areas on the leaves. These areas will never heal, so the leaf will be scarred for its' life.
#3. To acclimatize your succulents to the sun, introduce them to the great outdoors gradually. For the first 3 or 4 days place them in the shade all day. After that, place them in a partly shady spot for another few days and then they can go into the direct sun in about a week.
#4. Your succulents don't HAVE to be placed in the direct sun for the entire day. Most succulents will be happy all summer on a deck that may only get sun 3 or 4 hours of sun a day.
The main benefits of giving your plants a summer holiday are 3-fold:
- when your plants are outside they will be happier and appreciate the fresh air and its movement.
- you'll enjoy the benefits of added colour and less stretching of your plants (unless you're watering them too much).
-they will gain strength with direct sunlight which will give them more energy to help get them through our terribly LONG winters.Overwintering Living Walls
In our living wall class, you may have planted your wall with either all hen and chicks (sempervivum), all other succulents that can't freeze or a combination of both. If your wall has nothing but hen and chicks in it skip to the next paragraph. If planted with all succulents that can't freeze (all succulents other than hen and chicks that are non-hardy in our climate) you can either overwinter the entire wall indoors or pull out the plants and plant them in pots either individually or like we do in the succulent bowl class - group together in a lovely arrangement using as many bowls as you need. If your wall has a combo of both types then you must separate the hen and chicks from the non-hardy succulents. For overwintering the non-hardy varieties be sure to read the section 'OVERWINTERING" above
The ABSOLUTE best way to overwinter the hen and chicks in your living wall is to lift them and plant them in your garden in the fall. Make sure they have thick snow cover all winter (it's good to have a place to pile all that driveway snow). Then in the spring you can lift them and plant them back into your living wall (It's so much fun to replant them into the wall in the spring and make up a new design). This is a little more work than just setting your planted living wall outside and hoping it will survive. Having said that, many of our living wall clients have very successfully overwintered their living walls right in their frames. If trying this, be sure your plants have a good snow cover as well.Bugs:
If you can see bugs on your succulents (aphids, fruit flies or cotton ball-like "downy mealy bugs"), use End All. End All is a green product made with pyrethrum (from the citronella plant).
Before you take your plant indoors in the fall, give it a good spray with End All. Spray from the edge of the bowl inwards, up and around, under the leaves. Wear a pair of rubber gloves and a respirator when spraying your plant in order to take proper safety precautions.
We always have End All in stock year round.
If you see small cotton balls on your plants you have mealy bugs. Before spraying with End All it will definitely help if you first remove any cotton balls that you see with a Q tip.
Unfortunately bugs are a fact of life and can occur on your plants any time of year. Of course bugs can attack your plants when outside and can be transferred into your house if you are overwintering your plants. Also, bugs and bug eggs can be brought into your house at any time of year. Small bugs and their tiny (usually invisible) eggs can be brought into your house by hitching rides on fruits, vegetables and grains that you buy at the grocery store. If your plants seem bug-free in the winter and then suddenly bugs appear (especially those annoying, tiny flying fruit flies) then they (or their eggs) have hitched a ride directly from the grocery store to your kitchen. The key is to be vigilant all year-round. Inspect your plants every week (even in the winter). It is much easier to deal with a few insects than a whole swarm of them.
End All is an oily substance that will stay on the plant surface for a couple of months and will actually enhance the colour of your plant! Solar Gardens carries it year round in our retail centre. As succulent specialists, we can say that End All in our experience is safe on succulents. However, if you are considering using it on non-succulent plants, we cannot guarantee that End All will be safe on all plants. You would need to research that as all plants are different.
Solar Gardens uses a systemic commercial product in late February and early March, which is drenched into the soil for the new active roots to absorb the chemical and ensure no bugs will exist. The chemical we use lasts for 8-9 months, and a one-time application per year is all that is needed. This doesn't mean that bugs cannot exist on the plants. But it does mean that for 8-9 months after our drenching, any bugs that bite into this plant will ingest the chemical and die.
Mealy-bug infestations can also be managed using a commercial product. Only commercial growers have access to it. It's expensive and requires additional precautions. As a result, it is not available to the general public. If you have a severe infestation, we can treat your succulents for you using this commercial product at our acreage.
