What pot is good for Medinilla?

Q: I just acquired a Medinilla plant. I have a cylindrical tall clay pot that I would like to repot this beauty into. Would like to know if a deep pot is good for this type of tropical plants even if the medium is lightweight with bark and perlite allowing adequate drainage. Would appreciate your advice.

A: Medinillas are very close to epiphytes, meaning they like high air humidity and very good soil drainage characteristics. Clay pots usually provide good air circulation, as long as they are not glazed. If you add a lot of soil conditioner into your mix, like orchid mix and perlite, the tall pot will provide a good drainage. Tall pot is also great for displaying the beautiful pendulous blooms!

Plastic pots work well too, as long as you provide a well-drained soil for the plant. If a nursery plastic pot is not pretty enough, you may place it in a fancy planter; however, make sure never let the pot sit in water, Medinillas do not like wet feet.

How to keep iguanas away?

Q: Really enjoy all the plants that I have got from you, but having a hard time keeping iguanas eating everything! We are not on the water, any solution to keep them out?

A: Iguanas may become quite a problem in the garden. Our first suggestion would be - get a Duck as we have (Duck Dobi), she is so dominant and keeps any wild animals away from the property, including gators... and cats! They are scared of her! Dobi thinks she owns the place.

Here are a few other ways to control iguana problem in your backyard:

1. Rid your lawn of dropped fruits. Iguanas love fruit. And they love low-hanging fruit or fruit that's easy to get to. If you have fruit trees, take the time to pick up your yard and dispose of any dropped fruit.
2. Keep a lid on a garbage can. Put your garbage cans in a place they can't get to, or put a cinder block on your can lid.
3. Do not leave pet food out. If you're putting a bowl of dog food or a plate of cat food out for your pets, you're inviting iguanas into your yard.
4. Fill iguana holes. Iguanas like to dig. Wherever you see a hole, fill it. Stuff rocks into the hole first, then fill it with dirt and top it with sod. The iguana may return to dig again, but he won't dig through large rocks.
5 Do NOT feed the iguanas. Don't be friendly with them, so they won't come back.
6. Wire netting around plants. You can use wire netting or screens to prevent iguanas from entering plants and shrubs.
7. Spray them with a hose. When you see an iguana in the yard, spray them with the hose. They also hate loud noises. Constant harassment can keep them from returning.
8. Keep your yard clean. Excessive overgrowth or yard storage are great places for iguanas to hide.
9. Do not leave food out, unattended. Iguanas are mainly herbivores but that doesn't mean they won't smell something good and want to eat it. They will TRY anything.

Hopefully these tips help keep your iguana problems to a minimum.

How to grow Parijat indoors in winter

Q: I purchased Parijat plant last year spring. It had good growth in Summer, after that I kept the plant inside the house in winter. A couple of weeks it was ok, after that the plant lost leaves. What is a better idea for growing Parijat plant indoors in Winter?

A: Nyctanthes arbor-tristis, Parijat - is a semi-deciduous plant, which means, it may lose its leaves during unfavorable conditions such as drought, cold, low light and/or humidity. In your case, the plant dropped leaves because of the stress of moving indoors that includes reducing light and humidity levels. When a tropical plant loses leaves during winter, this means it goes into a dormant stage. If this happens, you need to reduce watering and keep the plant on a dry side, water in only when the top level of the soil feels dry to touch. Do not fertilize.
Try to place the plant in a well-lit spot such as a windowsill. If the windowsill and the window glass feel too cold for touch during wintertime, you may place a sheet of a Styrofoam underneath the pot, and a sheet of a bubble-wrap between the plant and the window glass, to create an extra barrier from cold. The plant may re-leaf during wintertime; if not, it may wait until spring, be patient.
Bring it back into outdoor light when minimum temperatures rise above 65F and resume fertilizing.

Repotting Artocarpus with a taproot in ground

Q: The Chempedak I bought from you almost 3 years ago which I had repotted twice has a thick taproot growing in the ground, which I noticed this past winter. I was going to repot into the largest size pot almost half of a 55-g rain barrel. Can I try to dig/save as much of the taproot before repotting, will it die if I had to shorten/cut what I can't dig out completely? I hate to put it in the ground for fear it may not make it when we have severe cold/long hours of frost. I live in west Cocoa, Central Florida, 9b.

A: Yes, you can repot the tree and keep it in reasonable size container after trimming the roots. Most of the tropical trees (fruit trees not an exception) can be grown in containers even if in Nature they grow into vigorous large trees. The key is, trim the roots every time you transplant it. The process is similar to trimming branches and both don't hurt the plant as long as done right and moderately. You should trim the overgrown and spreading limbs at the same time. You may trim as much as 10% off root system at the time of repotting. This will cause the root system to branch out and become fuller, similar to branches, which is a good thing. If a tree grows a taproot like in your case, it is not necessary to try "saving" and digging out the whole root that may go down for a few feet. You may cut it off without major damage to the tree since the rest of its root system will continue to support the plant metabolism. Just keep in mind that the plant will be stressed for a while - so put it in bright shade and water regularly until signs of stress go away (wilted or dropping leaves may occur). This particular type of tree - Artocarpus - is pretty strong and vigorous so the stress should be minimal.

How to get Strophanthus tree to bloom?

Q: I purchased from you three of these plants - Strophanthus bovinii and I wonder if you could help me. The plants are out of control growing large limbs to the sides and I would like it to grow more upright. Is this possible? Second, it does not flower. What type of fertilizer should I use and how often? How about the watering schedule? I have them in an eastern exposure but possibly they are not getting enough sun? Right in front of them, there is a large tree outside the curb of my house. What should I do about that?

A: Strophanthus bovinii - Wood shaving flower, is quite a unique plant that is very rare in cultivation, this is why very little information is available on its cultivation due to limited experience among gardeners. We have had this plant in our garden for over 12 years and this is what we can advise.
In the nature (Madagascar) it supposedly grows into a large tree, however, from our experience, it tends to be rather bushy, umbrella-like large shrub. Yes, you can train it into a tree by trimming branches growing side-wise, and by removing lower branches. The best time for pruning is early spring when the tree starts new growth and re-leafs (it is semi-deciduous). As far as flowering, the plant is very particular about blooming season, with profuse flowering in Summer (here in SW Florida), however it may produce more flowers sporadically throughout the year.
It thrives in full sun but will tolerate bright filtered light. If a large tree is shading it too much, try to trim some limbs of that large tree to allow more light. Water needs of Strophanthus bovinii are very moderate, so you can rely on your sprinkler system or water once a week for established plants.
You should use 2 types of fertilizers - slow release (once a month) and water-soluble bloom booster (frequent applications are safe):
