LadyBugs guarding your plants!

Q: I have a bunch of Ladybugs in my garden, I wonder if they eating my plants? Do I need to get rid of them?

A: Ladybug (Harmonia axyridis) is, in fact, one of the best insects you can find in your garden, it is a natural predator that takes care of many bad bugs, including aphids. Keep them happy and bring them to your garden. Ladybugs actually are cultivated as natural pest control, and you can even buy them for your yard, instead of chemicals!

Ladybug larvae eating aphids:

The wonderful insects that dine only on landscape pests and don't harm good bugs or plants are called 'beneficials', and ladybugs definitely fall into this category, but not the way many people think. It's the ladybug's larvae that are voracious predators of soft-bodied problem insects, especially aphids.

When is the time to repot?

Q: According to your instructions, I understand that plants need to be placed in bigger pots. But my question is, say I plant each plant in 18in x 18 in x 18 inch square pots, how many weeks, months or years can the soil be good for these plants? When will it be time to change soil? Any specific soil recommendations?

A: Repotting is required usually once a year. It depends on the plant and growth rate of course. The best way to check if a plant needs stepping up is to check its root system. Carefully turn the pot upside down and pull the pot off the roots (make sure to support the plant from the bottom). If a root system is very dense, it is time to repot. It is an easy check with smaller plants; if a plant is large and hard to turn "upside-down", check drainage holes: if roots start growing through the holes, it is definitely time to step up. Make sure to use pot size only a few inches bigger in diameter than the existing one: just enough for the root system plus 2-3 inches extra space; do not use oversized pots to avoid root rot. Use only new quality potting soil and make sure it has perfect drainage characteristics. We recommend Professional Soilless Mix

When to fertilize and prune tropical fruit trees?

Q: Can tropical fruit trees (Soursop, Mango, Star fruit, etc) be given plant food any time of year? Also can they be trimmed this time of year/summer?

A: True tropical plants (including fruit trees) need plant food most of the year in real Tropics, where temperatures have very little fluctuations, and active growth season is close to 12 months a year. In subtropical areas when temperatures in winter drop below 65F, plant metabolism slows down, so it is recommended to fertilize only during the warmest period (March through November). So yes, Summer is the perfect time for fertilizing your trees; their metabolism is at the highest point and they can use more food!

Trim your fruit trees right after harvesting. Obviously, you don't want to prune branches before or during flowering or fruiting. The specific time of the year for pruning depends on the plant - every tree has its own flowering/fruiting season. However, avoid pruning right before winter: young shoots promoted by pruning are tender and can be cold damaged.

Recommended fertilizers for fruit trees:

Fruit Festival Plant Food - Super Crop Booster
Mango-Food - Smart Release Fruit Tree Booster
SUNSHINE-Honey - for sweeter fruit
SUNSHINE SuperFood - microelement supplement

Growing desert roses

Q: I purchased a Desert Rose and planted it in Adenium mix. I keep it in full sun with once a week watering assuming this is a desert plant that likes lots of sun. Some leaves turned yellow and now I am not sure should I move it into shade or need to water more? Or maybe fertilize with something?

A: Desert Rose - Adenium, unlike cacti and other succulents, prefers filtered light. It can grow in full sun but leaves look healthier in light shade. Watering must be very moderate, however don't let soil harden like a rock: water again right after the soil gets dry. We suggest to use special Adenium Mix. Cactus mix may work well, as well as regular potting mix, in which case it is recommended to add a bit of limestone (we simply put sea shells on top of the pot - it looks very pretty!) - because adeniums prefer slightly alkaline soil (while most of tropical plants like acidic soils). If leaves turn yellow, this may be a sign of underwatering. Use water soluable fertilizer with high phosphate as foliage spray, and only on healthy plants, according to label dosage. It helps both caudex growth and flowering. Make sure to avoid fertilizer contact with a caudex.

Adenium Plant Food - Flower and Caudex Booster
SUNSHINE-BC - Caudex booster
Adenium Soilless Mix

How to propagate plants from cuttings. Top (Tropicals) secrets.

TopTropicals.com

Q: After pruning my jasmine, I have so many branches and I don't have a heart to through them away, can I use them to make more plants? Please tell me what size cuttings and do I need to remove leaves? Should I just stick them in the ground? Will they root? I don't know if you will be willing to share your secrets?

A: We are always happy to know that you grow more plants, and make our World better! These are some useful tips for the propagation of tropical plants using cuttings:

- Cuttings and leaves. Use cuttings 2-5"long. Strip leaves from the bottom. Cut larger leaves in half to reduce evaporation.
- Soak cuttings for 15-30 min in SUNSHINE solution.
- Mix. Use special well-drained mix with lots of soil conditioner: we have a special professional propagation mix for cuttings.
- Mist. Put community pots or trays with cuttings in mist, or if you don't have mist - cover the pot with a clear plastic bag to create a mini-greenhouse.
- Shade. Keep propagation pots in bright shade and never allow direct sun rays.
- Rooting hormone: yes, use it if you have it. Not only it promotes root formation but also prevents from fungus so the cuttings won't rot. We use Dip-N-Grow.
- Rooting and food. Check in 2-3 weeks for roots. Once you see the little roots, begin fertilizing with a special Baby-Plant Food and make sure never exceed recommended doze otherwise you may kill the cuttings.
- Establishing. Once roots start growing, plant in 4" pots in a well-drained potting mix and watch the beauty grow! Gradually move to the full sun only when little plants establish and start new growth.

If you are lucky to make more rare plants than you can use, contact us, we will buy them from you or trade for your dream plants! In fact, one of our customers from many years ago started selling us baby plants that he propagated from our plants, and now has a successful business (Karma Nursery); we buy a lot of plants from him every month!
