were turning down ward looking wilty any suggestions as to what might have
happened over night? please help as to we have put alot of time and money and
patiance into these plant and would love to save them? thank you
Dear Jennifer:
Sorry it has taken so long to get back with you. Do make sure that you have an ability to vent
the gas by-product from your heater. I agree, you need to keep the tomato plants above freezing,
but some gas heaters give off deadly gases which is the same reason we don’t use them around
people in an enclosed area without proper ventilation.
The process of growing plants is certainly one that most of use the trial-and-error system.
My best,
Stan

Hi Stan, I live in north jersey, not a real rainy climate in the summer but
every year come end of july, august I get hit with black spot, it’s like clock
work. I try everything. I spray with orthos disease control as recommended
before it hits and then do everything that is recommended by everybody when it
hit and nothing stops the block spot. I remove all the leaves that are infected
into the garbage, I remove the top layer of soil and give a good spraying and
with in a week it is back. by the end of the summer my bushes have no leaves
left on them every year. I have decided to buy 10 new disease resistant rose
bushes and get ride of the ones I have. It just bothers me that- thats what I
have to do to get good bushes. Any advise before I do this. I have tried
everything. Thank You Stan
Dear Michael,
It sounds like you are doing all the right things. Maybe these need disease resistant roses will decrease your problems.
Planting them where they will be get the early morning sunlight, often helps the leaves to dry early and cuts down on some
of this fungal problem. Let me know how these new roses do for you.
My best,
Stan

im having a hard time learning how often to water my garden…i live in north
florida…and i planted some onions and brocoli and radishes last november and
got absolutely no harvest…so im trying again..but i want to know , how often
should i warer my garden..thanks
Dear William,
How often to water depends upon a number of factors. How much organic matter is in the soil? This helps to hold water. It is one
of the reason most commercial soils have a good deal of organic matter, such as peat and/or compost mixed in with other elements
such as wood chips, bark and inert ingredients such as perlite. Small plants require more water than established plants. Remember,
the Horticultural rule: if a plant dries, it dies. Most gardens should be in an area with 6-8 hours of sunlight daily. Plant where the garden
will not be in direct competition with the roots from other plants, shrubs and trees.
My best,
Stan

Any suggestions?
Dear Trish:
My next Home Show will be in June at the Tropicana Field, you could bring a soil sample. Consider growing junipers and/or dwarf hollies (cold hardy) which are very excepting of our Florida sand. Improving the soil with peat moss and Black Kow manure would also be a good first start. Make sure the mulch is a couple of inches thick and that water is being applied during the dry times.

Hello my question is that i have a dieffenbachia house plant. I have seen gnats
around the top of the soil but just a few. I spray them with a garlic solution
or sometimes a soapy spray for plants because i though they were whiteflies. But
i started seeing them more on the bottom of my pot. I don’t know what to do to
get rid of them.. My other plants which are dracena or corn plants are ok. I see
maybe on or two in the top dirt but not like my other plant.
Dear Rosalina:
Try a Neem oil on houseplants, it’s low toxicity makes it friendly in the home setting. There are a number of pesticides labeled for indoor use. The fungus gnat often comes in some of our potting soils. Sometimes re-potting in fresh, new soil is a more simple solution than spraying the base of the plant repeatedly.
My best,
MRGT
For most parts of the country, spring has sprung and summer is just around the corner. Many of your favorite plants were injured by the cold. How do you know if these plants will survive? Use a pocket or paring knife to scrape along the outer bark of the stems working your way back from the tips to the base of the trunk. In some cases, it may be dark brown along the edges, keep working until you find a light green cambium layer; at this point, Mother Nature has made a decision for you. Trim off all dead plant material.
Question: I have about 25 different varieties of tomatoes in my Tarpon Springs garden. I have noticed that the leaves are getting these brown spots on top of them. I do not know what this is, can you help?
Wow, 25 different varieties! This is very impressive and I would like to say I am envious of your crop diversity. If you are or did experience brown spots on your leaves you have a fungus in my opinion. Not to worry you have options in helping your success for your next years crop, I would recommend getting some Dithane M45 or any other general fungicide and be certain to follow the label instructions to the letter.
Question: I have a small greenhouse business and this year I seem to have a problem with a green-like algae/ fungus that grows on the surface of my pots and flats. What is it and how do I get rid of it? Will Decree fungicide work?
You are correct it is green algae and your more than welcome to try “Decree” Fungicide, but my understanding of that product is that it is very specific in its inhibiting mode of action. One idea for you would be to be very careful in how you use this but you could use a diluted concentration of bleach and clean your planting beds, trays, and other equipment that the algae is growing on. Keep in mind algae has very little effect on plant growth and nearly every greenhouse has some algae growing within it.
When plants are trimmed, the diseased parts are removed, and pruning roses involves doing just this, as well as maintaining the shape of the plant. Keep the stem of a rose healthy with help from an urban horticulturist and gardening adviser in this free video on growing roses.
Temperature has a great effect on plants, as very hot and very cold weather can prevent a plant from setting blooms, and it can even cause the plant to start dropping foliage. Keep plants at their proper temperatures for the best results with plant advice from an urban horticulturist in this free video on gardening.
